CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority from U.S. Provisional Patent Application No. 62/004,706, filed on May 29, 2014, which is incorporated by reference herein in its entirety.

BACKGROUND

[0002] There is much current interest in the food industry in plant-based protein concentrates from, for example, soybeans, corn, wheat, and other protein containing grains. Plant meal may be conventionally extracted with alcohol to remove carbohydrates. The extraction process may increase the amount of protein, but may be inefficient or ineffective at removing non-digestible matter conventionally referred to in the field as Anti-Nutritional Substances (ANS). Plant-based meal may include ANS such as trypsin inhibitors, antigens (glycinin and b-conglycinin), phytic acid, and non-digestible oligosaccharides such as stachyose and raffmose. Stachyose and raffmose may be the most challenging ANS to remove from plant-based meal products.

[0003] Further, for example, conventional chemical methods of separating ANS polysaccharides from soybean meal typically may remove only half of such polysaccharides. For example, conventional processes may convert soybean meal containing about 50% proteins and about 40% polysaccharides into a soy protein concentrate containing about 70% proteins and about 20% polysaccharides. Biochemical processes such as microbial and enzymatic degradation may convert polysaccharides to oligosaccharides or more soluble sugars, but such processes may cause hydro lytic cleavage of proteins (e.g., in soybean meal), resulting in degraded protein and lower nutritional value.

[0004] An example use of plant-based meal limited by the presence of ANS is in aquaculture feed. Protein in conventional aquaculture feed is based on fish meal, which is costly and has an undesirable environmental impact. It is desirable to supplement or replace fish meal in aquaculture feed with plant-based meal, such as conventional soy protein concentrate. However, conventional soy protein concentrate still includes ANS, e.g., non-digestible oligosaccharides such as stachyose and raffmose, which are poorly digested by many fish, lead to impaired growth, and may be rejected, especially by carnivorous fish such as cod or salmon. In addition, undesirable "fishy" or "earthy" flavors may develop. Consequently, the amount of fish meal that can be replaced by plant matter such as conventional soy protein concentrate is limited by ANS.

[0005] The present disclosure appreciates that improving plant meal by removing anti- nutritional substances may be a challenging endeavor.

EXAMPLES

[00103] EXAMPLE 1.0: Chemical treatment of soybean meal with 1.5% hydrogen peroxide and catalyst at atmospheric pressure.

[00104] A 3-neck 500 mL round bottom flask was fitted with: an overhead stirrer, using only glass and polytetrafluoroethylene stirring components; a polytetrafluoroethylene coated thermocouple; a heating mantle and heating mantle controller; a water cooled condenser; and a gas inlet for purging, coupled to an argon gas source. About 50.03 g of defatted soy flour (NUTPvASOY® 7B, Archer Daniels Midland, Decatur, IL), 52.2 mg manganese oxide (cat# 63548, Sigma-Aldrich, St. Louis, MO) and 235 g of steam distilled water was added to the flask to form a reaction mixture. The mixture was stirred and heated to 60 °C under an argon purge. When the mixture appeared as a uniform slurry, about 15.23 g of a 30% aqueous solution of hydrogen peroxide was added drop-wise while maintaining the temperature at 60 °C. The reaction mixture was stirred at 60 °C for 1 hour, then allowed to cool to ambient temperature overnight while mixing. The resulting solution was a light tan color, similar in color to the starting reaction mixture.

[00105] EXAMPLE 1.1: Procedure for chemical treatment of soybean meal with 1.5% hydrogen peroxide and catalyst at high temperature and pressure.

[00106] A 100 mL pressure reactor (PARR, Moline, IL) was fitted with a stirrer and a gas inlet. About 33.33 g of defatted soy flour (NUTRASOY® 7B, Archer Daniels Midland, Decatur, IL), 35.2 mg manganese oxide (cat# 63548, Sigma- Aldrich, St. Louis, MO) and about 156.67 g of steam distilled water was added to the reactor to form a reaction mixture. About 10.0 g of a 30% aqueous solution of hydrogen peroxide was added to the reaction mixture at once before closing the reactor cap. The reactor was charged with nitrogen gas at 222 pounds per square inch (PSI) then heated to 120 °C. The reaction mixture was mixed at 120 °C for 1 hour, then the heating was removed and the reaction mixture was allowed to cool to room temperature while mixing. The resulting solution was jet black in color with a strong odor.

[00107] EXAMPLE 1.2: Procedure for chemical treatment of soybean meal with -1.5% hydrogen peroxide and catalyst at elevated temperature and pressure.

[00108] A 100 mL pressure reactor (PARR, Moline, IL) was fitted with a stirrer and a gas inlet. About 33.72 g of defatted soy flour (NUTRASOY® 7B, Archer Daniels Midland, Decatur, IL), 32.8 mg manganese oxide (cat# 63548, Sigma-Aldrich, St. Louis, MO) and about 157.5 g of steam distilled water was added to the reactor to form a reaction mixture. The reaction mixture was made into a uniform slurry with no clumps using a homogenizer (IKA® Works Inc., Wilmington, NC). About 10.0037 g of a 30% aqueous solution of hydrogen peroxide was added to the reaction mixture at once before closing the reactor cap. The reactor was charged with nitrogen gas (about 240 PSI), then heated to 60 °C. The reaction mixture was mixed at 60 °C for 1 hour, then the heating was removed, and the reaction mixture was allowed to cool to room temperature while mixing. The resulting tannish brown mixture was centrifuged to separate a supernatant fraction from a solid fraction. Both fractions were freeze-dried. The freeze-dried portion of the liquid fraction was about 11.32 g, and the freeze-dried portion of the solid fraction was about 15.31 g. These results indicate that about 42% of remaining solids were water soluble in the liquid fraction.

[00109] EXAMPLE 2: Procedure for chemical treatment of soybean meal with -0.75% hydrogen peroxide and catalyst at elevated temperature and pressure.

[00110] A 100 mL pressure reactor (PARR, Moline, IL) was fitted with a stirrer and a gas inlet. About 33.40 g of defatted soy flour (NUTRASOY® 7B, Archer Daniels Midland, Decatur, IL), 16.2 mg manganese oxide (cat# 63548, Sigma- Aldrich, St. Louis, MO) and about 155.25 g of steam distilled water was added to the reactor to form a reaction mixture. The reaction mixture was made into a uniform slurry with no clumps using a homogenizer (IKA® Works Inc., Wilmington, NC). About 5.0218 g of a 30% aqueous solution of hydrogen peroxide was added to the reaction mixture at once before closing the reactor cap. The reactor was charged with nitrogen gas (about 243 PSI), then heated to 60 °C. The reaction mixture was mixed at 60 °C for 1 hour, then the heating was removed and the reaction mixture was allowed to cool to room temperature while mixing. The resulting tannish brown mixture was centrifuged to separate a supernatant fraction from a solid fraction. Both fractions were freeze-dried. The freeze-dried portion of the liquid fraction was about 6.16 g, and the freeze-dried portion of the solid fraction was about 15.33 g. These results indicate that about 28%> of remaining solids were water soluble in the liquid fraction.

[00111] EXAMPLE 3: Treatment of soybean meal with enzyme cocktail.

[00112] A IL reactor was fitted with an overhead stirrer, a thermocouple, a heating mantle with temperature controller, a water cooled condenser, and a homogenizer (IKA® Works Inc., Wilmington, NC). About 110.25 g of defatted soy flour (NUTRASOY® 7B, Archer Daniels Midland, Decatur, IL) and about 1 volumetric L of steam distilled water was added to the reactor to form a reaction mixture. The overhead stirrer was set to high to high to disperse the soy, and the homogenizer was set to a setting of 3. The pH of the reaction mixture was adjusted to 6.02 with glacial acetic acid by monitoring with a pH meter and slowly adding acid. An enzyme cocktail (about 0.51 g of a multi-enzyme complex containing a wide range of carbohydrases, including arabanase, cellulase, β-glucanase, hemicellulase, and xylanase; VISCOZYME® L, cat# V2010, Sigma- Aldrich, St. Louis, MO) was added to the mixture by drop-wise addition. The reactor was heated to 60 °C and allowed to mix for 22 hours. The resulting mixture was cooled to room temperature and centrifuged to separate a supernatant fraction from a solid fraction. Both fractions were freeze-dried. The freeze-dried portion of the solid fraction was about 74.99 g. These results indicate that about 25% of remaining solids were water soluble in the liquid fraction.

[00113] EXAMPLE 4: Procedure for treatment of soybean meal with enzyme cocktail of EXAMPLE 3, and additionally, alpha-galactose and invertase enzymes.

[00114] A IL reactor was fitted with an overhead stirrer, a thermocouple, a heating mantle with temperature controller, a water cooled condenser, and a homogenizer (IKA® Works Inc., Wilmington, NC). About 110.65 g of defatted soy flour (NUTRASOY® 7B, Archer Daniels Midland, Decatur, IL), 16.2 mg manganese oxide (cat# 63548, Sigma- Aldrich, St. Louis, MO) and about 1 volumetric L of steam distilled water was added to the reactor to form a reaction mixture. The overhead stirrer was set to high to disperse the soy, and the homogenizer was set to a setting of 3. The pH of the reaction mixture was adjusted to 6.02 with glacial acetic acid by monitoring with a pH meter and slowly adding acid. The reactor was charged with 4 tablets containing alpha-galactose and invertase enzymes (1.41 g, of BEANO®, Prestige Brands, Tarrytown, NY), and the reaction mixture was stirred for three days. An enzyme cocktail (about 0.54 g of VISCOZYME® L, cat# V2010, Sigma- Aldrich, St. Louis, MO) was added to the mixture by drop-wise addition. The reactor was heated to 60 °C and allowed to mix for 22 hours. The resulting mixture was cooled to room temperature and allowed to mix for 2 days. The resulting mixture was centrifuged to separate a supernatant fraction from a solid fraction. Both fractions were freeze-dried. The freeze-dried portion of the solid fraction was about 56.54 g. These results indicate that about 36% of remaining solids were water-soluble in the liquid fraction.

[00115] EXAMPLE 5 A: Bulk treatment of soybean meal to produce improved meal.

[00116] A 1 gallon pressure reactor was preheated to 60 °C and charged with a homogenized mixture of 578 g toasted soy flour, 2600 g of deionized water, and 5.5 g of manganese dioxide. The reactor was closed and the reactor bolts were tightened with a torque wrench. An addition vessel was charged with 170 g of 30%> aqueous hydrogen peroxide and was fixed in-line with an inert gas inlet coupled to an argon source. The reactor was charged with 230 PSI of argon and the 30%) aqueous hydrogen peroxide was forced into the reactor with the argon pressure. The reaction was stirred for 1 hour and then the produce was immediately removed from the pressure reactor.

[00117] EXAMPLES 5B-Q: The process described in EXAMPLE 5A was repeated batch- wise 16 more times for a total of seventeen times.

[00118] EXAMPLE 5R: Preparation of dried, treated and preserved improved meal

[00119] The resulting combined dispersed flour slurry from EXAMPLES 5A-Q was centrifuged to separate a liquid supernatant fraction and a solids fraction as a cake. The solid cake was flash-frozen in liquid nitrogen and the resulting frozen solids cake was freeze-dried, resulting in brittle flaky chunks. The freeze-dried solids were ground to a texture of crumbly flour. The freeze-dried solids in crumbly flour form were collected to achieve 15.8 pounds of treated flour. The 15.8 pounds of treated flour was further mixed with about 34.1 g of potassium sorbate and about 13.71 g of sodium benzoate to give a treated and preserved improved meal.

[00120] EXAMPLE 6: Proximate analysis and determination of ANS reduction via various methods.

[00121] Samples were obtained for ANS carbohydrate removal using mechanical extraction with water, chemical oxidation according to EXAMPLE 5A, and enzymatic hydrolysis according to EXAMPLE 3. Additionally, samples of soy milk were obtained before and after bacterial fermentation with Lactobacillus. All samples were dried and ground to a fine powder by using a coffee grinder (Severin, KM 3872, 230 V and 90 W, Severin Elektogerate GmbH, Sundern, Germany) prior to analysis. The proximate composition of the experimental feeds was determined, i.e. for moisture (oven-drying at 105 °C overnight), crude protein by CN analyser (Vario Max CN, Makro-Elementaranalysator, Element analysensysteme GmbH, Hanau, Germany) (N X 6.25), fat by extraction, non-starch polysaccharides/carbohydrates or ANS, and ash (oven incineration at 480 °C overnight).

[00122] FIG. 3 is a graph 300 showing the relative weight fraction of ANS carbohydrates removed using mechanical extraction (about 5 weight percent removed), chemical oxidation (about 15 weight percent or greater removed), and biochemical digestion via enzymatic hydrolysis (about 25 weight percent or greater removed). FIG. 4 is a graph 400 showing the weight fraction of ANS carbohydrates in soy milk before and after using biochemical digestion via bacterial fermentation with Lactobacillus. The total carbohydrate fraction of about 42 weight percent in fresh soy milk was reduced to about 30 weight percent in fermented soy milk; thus, the weight percent reduction according to biochemical digestion via bacterial fermentation was about 12 weight percent. The raffinose and stachyose content of the product meal is less than 0.5 weight percent.

[00123] EXAMPLE 7: Comparative feed trial results in yellow perch. [00124] Diets: Nine fish feed diets were prepared as described in FIG. 5, table 500, and FIG. 6, table 600 as follows.

[00125] Diet 2 was formed with 50% of the fish meal protein from diet 1 replaced by roasted soybean meal (RBSM). Diet 3 was formed with 100% of the fish meal protein from diet 1 replaced by RSBM. Diet 4 was formed with 50% of the fish meal protein from diet 1 replaced by RSBM and combined with the enzyme cocktail. Diet 5 was formed with 100% of the fish meal protein from diet 1 replaced by RSBM and combined with the enzyme cocktail. Diet 6 was formed with 50% of the fish meal protein from diet 1 replaced by soy protein concentrate (SPC), e.g., the improved meal.

Diet 8 was formed with 50% of the fish meal protein from diet 1 replaced by SPC, and combined with the enzyme cocktail. Diet 9 was formed with 100% of the fish meal protein from diet 1 replaced by SPC, and combined with the enzyme cocktail.

[00126] Yellow perch (Perca flavescens) were selected for trial and monitored for growth, nutrient and other performance attributes. The yellow perch (297; av wt.= 11 g) were prepared in nine groups with three replicates. Each group was housed in a flow through system (18 inch tank). The water parameters were maintained at a water temp: 19 - 24°C, pH: 6.5 - 7.6, DO: 6.5 - 7.7). The fish were hand- fed 2-3% of body mass of the above diets, 4 times per day, for a period of 10 weeks.

[00127] FIGS. 7 and 8 are graphs 700 and 800 showing various results of this EXAMPLE. FIG. 7 depicts graph 700, showing body weight gain in percent across diets 1-9. Roasted soybean meal diets 2-5 showed lesser weight gain compared to control diet 1. Roasted soybean meal diets 2 and 3, with 50% of the fish meal protein from diet 1 replaced by RSBM, showed better performance than diets 4 and 5, respectively, with 100% of the fish meal protein from diet 1 replaced by RSBM. Further, diets 3 and 5, with addition of the enzyme cocktail, showed better performance, respectively, than diets 2 and 4, without the enzyme cocktail. Soy protein concentrate diets 6 and 7, with 50% of the fish meal protein from diet 1 replaced by RSBM, showed comparable performance to control diet 1 and better performance than diets 8 and 9, respectively, with 100% of the fish meal protein from diet 1 replaced by SPC. Further, diets 7 and 9, with addition of the enzyme cocktail, showed better performance, respectively, than diets 6 and 8, without the enzyme cocktail.

[00128] FIG. 8 depicts graph 800, showing body feed conversion ratios in total dry feed fed in g/ total body mass gain in g across diets 1-9. Roasted soybean meal diets 2-5 showed less efficient feed conversion ratios compared to control diet 1. Roasted soybean meal diets 2 and 3, with 50% of the fish meal protein from diet 1 replaced by RSBM, showed better performance than diets 4 and 5, respectively, with 100% of the fish meal protein from diet 1 replaced by RSBM. Further, diets 3 and 5, with addition of the enzyme cocktail, showed slightly better performance, respectively, than diets 2 and 4, without the enzyme cocktail. Soy protein concentrate diets 6 and 7, with 50% of the fish meal protein from diet 1 replaced by RSBM, showed comparable performance to control diet 1 and comparable performance, respectively to diets 8 and 9, with 100% of the fish meal protein from diet 1 replaced by SPC. Further, diets 7 and 9, with addition of the enzyme cocktail, showed better performance, respectively, than diets 6 and 8, without the enzyme cocktail.

[00129] Based on this fish trial there is a potential to replace a portion of fish meal in aquaculture feeds. In this example, 50%> to 100%) of fish meal could be replaced compared to the control diet.

[00130] PROPHETIC EXAMPLE 8: Feed manufacturing.

[00131] The treated and preserved flour from Examples 5A-5Q will be ground in a hammer mill through a 0.8-mm screen, mixed, preconditioned and extruded in a screw extruder equipped with a 1.0 - 2.0 mm die. The extrusion process will be optimized to obtain a bulk density >520 g/L in the pellets before drying, in order to facilitate slow sinking of the feed after drying. The pellets will be dried to 930 g/kg dry matter and then coated with cocktail enzymes using a mini- coater. The diets will be formulated to be equal in protein (~38% of wet basis), lipid (~10% of wet basis) and digestible energy (-21 MJ kg ^-1 ), and designed to vary in the type and inclusion level of the protein source. The following feeds will be manufactured.

[00132] PROPHETIC EXAMPLE 9: Fish feeding and sampling.

[00133] Feed-trained yellow perch fish (nos. 324, wt. ~ 25 - 30 g) will be stocked into each of three flow-through tanks (replicates) for each diet feeding group (treatment and feed control), and be acclimated for two weeks before the experiment. Fish will be fed to satiation, and mortality will be monitored during the period of acclimation. Once experimental fish feed normally, the experiment will start with 12 fish per tank/replicate. During the experiment, all fish from each tank will be weighed individually each week. Throughout the experiment, fish will be fed the experimental diets using automated feeders delivering pellets from a conveyor into the tanks at programmed intervals. Feeding rates will be 2.5-3.0% of body weight (BW). Feed amounts will be calculated and adjusted weekly based on biomass estimates. Each diet will be fed to fish in duplicate tanks, and the fish will be fed three meals per day (08:00, 14:00 and 20:00 h). Water exchange rates in all tanks will be kept the same. Daily water temperature and DO will be recorded for each tank, and pH, ammonia and nitrite will be monitored weekly.

[00134] Uneaten feed will be sieved from the outlet water and feed intake will be monitored. At the beginning and the end of the experiments, fish from the tank will be euthanized with an overdose of MS-222, and stored at -20 °C for whole body proximate analyses and mineral compositions.

[00135] PROPHETIC EXAMPLE 10: Proximate analysis and determination of ANS and amino acids.

[00136] All samples will be ground to a fine powder by using a coffee grinder (Severin, KM 3872, 230 V and 90 W, Severin Elektogerate GmbH, Sundern, Germany) prior to analysis. The proximate composition of the experimental feeds and of the fish carcasses will be determined, i.e. for moisture (oven-drying at 105 °C overnight), crude protein by CN analyser (Vario Max CN, Makro-Elementaranalysator, Element analysensysteme GmbH, Hanau, Germany) (N X 6.25), fat by extraction and ash (oven incineration at 480 °C overnight).

[00137] Trypsin inhibitor activity will be determined. Analysis of the lectin content will be conducted by haemagglutination assay. Phytate content of samples will be determined by a spectrophotometric procedure. Non-starch polysaccharides (NSP) will be determined. Amino acid composition of feed ingredients will be determined using an automated amino acid analyser after hydro lysing the samples with 6M HCl at 110 °C for 24 h. The sulphur-containing amino acids will be oxidised using performic acid before the acid hydrolysis. Tryptophan content of the above-mentioned samples will be determined spectrophotometrically.

[00138] PROPHETIC EXAMPLE 11: Growth performance and nutrient utilization.

[00139] Parameters of growth performance and nutrient utilization will be determined as follows.

Body mass gain (%) = [(Final body mass - initial body mass)/Initial body mass] x 100. Specific growth rate (g/day) = [((In final body mass in g) - (In initial body mass in g))/ number of trial days] x 100. Metabolic growth rate (MGR, g kg ^0'8 day ^"1 ) = (Body mass gain in g) / [((initial body mass in g / 1000) ^Λ °· ⁸ + (final body mass in g / 1000) ^A ° ⁸ )/2] / number of trial days.

The growth rate and body weight estimations will be calculated as thermal-unit growth coefficient (TGC) = 100 [(FBW ^1/3 - IBW ^1/3 ) χ (ΣΤ χ D) *], FCR = dry feed fed (g)/body mass gain (g).

Specific feed rate (%) = SGRxFCR.

Protein efficiency ratio = body mass gain (g)/crude protein fed (g); protein productive value (%) = [(final fish body protein in g - initial fish body protein in g) / total protein consumed in g] x 100.

Lipid productive value (%) = [(final fish body lipid in g - initial fish body lipid in g) / total crude lipid consumed in g] x 100.

Energy productive value (%) = [(final fish body energy - initial fish body energy )/(gross energy intake)] x 100.

Condition factor = [round weight (g) x 100]/[fork length (cm)] ³ ; HSI, CSI, ISI (%) = [organ weight (g)/round weight (g)] x 100.

Hepatosomatic index (HSI) = Liver mass (g) X 100 / body mass (g).

Intestinal somatic index (ISI) = Intestinal mass (g) X 100 / body mass (g).

[00140] PROPHETIC EXAMPLE 12: Digestibility measurement and efficiency of digestible nutrients and gross energy.

[00141] Faeces collection will be qualitative, as the experimental diets will contain an inert marker (Titanium oxide, Ti0 ₂ ). During last two weeks of the experiment, fish will be fed with a diet containing a marker (Ti0 ₂ ) for digestibility measurement and faeces will be collected daily. After each feeding the aquaria will be controlled for remaining feed; generally, there will be no feed residues left. Every day prior to the faeces collection, aquaria will be siphoned out to clean any residues. Subsequently, faeces excreted by the fish will be collected in separate beakers for each aquarium by siphoning with a short small pipe. Faeces and surrounding water will be gently withdrawn from the aquaria immediately after excretion to minimize leaching of soluble components into water. The collected mixture of water and faeces will be centrifuged at 4000 x g for 10 min, the supernatant will be discarded and the faeces will be then stored at -20 °C until analysis. For the analysis, faeces from all the experimental periods from the same fish will be pooled. The collected faeces will be centrifuged at 4000 x g for 10 min, the supernatant discarded and the faeces will then be stored at -20 °C until analysis. Titanium dioxide in the feed and faeces will be determined. The percentage of apparent dry matter digestibility of diets will be calculated as: Apparent dry matter digestibility (%) = [1 - {(% Ti0 ₂ in feed) / (% Ti0 ₂ in faeces)}] X 100. Apparent digestibility coefficients (ADCs) of nutrients and energy of the experimental diets will be calculated. The nutrient and energy digestibility will be obtained using the following formula:

Apparent nutrient digestibility (%) = [1 - {(% Ti0 ₂ in feed) / (% Ti0 ₂ in faeces) X (% Nutrient or energy in faeces) / (% Nutrient or energy in feed)}] X 100.

Digestible nutrients and gross energy retained (%) = (Nutrient and energy retained in the whole body/Digestible nutrient and digestible energy) XI 00.

Digestible nutrients and energy = Total offered of nutrients and gross energy through feed X digestibility coefficient.

[00143] Liver will be dissected from 2 fish of each replicate (6 fish/treatment) and transferred into liquid nitrogen for later analysis of alanine aminotransferase (ALAT, EC 2.6.1.2), aspartate aminotransferase (ASAT, EC 2.6.1.1), glutamate aminotransferase (GDH, EC 1.4.1.2), alkaline phosphates (AP, EC 3.1.3.1.) and lactate dehydrogenase (LDH, EC 1.1.1.27) activities. These enzymes will give valuable information on the liver function of the meal and protein concentrate fed animals. [00144] The frozen liver sample will be homogenized with an Ultra Turrax in ice-cold buffer (20mM Tris, 8mM Mg Cl ₂ , 5mM ethylenediamine tetraacetic acid (EDTA), 30mM KC1, 2.5 mM dithioerythritol (DTE) and protease inhibitor (P 8340, 1 ml/20g liver), pH 8.0) ( 1 g sample/9 ml buffer). Using commercial kits (ECOLINE®S ⁺ VWR, Holzheim, Germany; Sigma Chemical Co., Darmstadt, Germany) activities of ALAT, ASAT, AP and LDH will be measured after centrifugation of the homogenates at 10,000xg for 15 min at 4°C. For measurement of GDH activity, the homogenates will be centrifuged at 10,000xg for 5 min at 4°C. The supernatant will then be exposed to ultrasound (100 W, 1 min) to break mitochondrial membranes and centrifuged at 10,000xg for 15 min at 4°C. The activity of GDH will be measured using a commercial kit (ECOLINE®S ⁺ VWR, Holzheim, Germany).

[00145] Intestine will be also dissected from 2 fish of each replicate (6 fish/treatment) and transferred into liquid nitrogen for later analysis of digestive enzymes. Amylase activity will be estimated using a dinitro-salicylic-acid (DNS) method. Amylase activity will be expressed as mmol of maltose released from starch per min at 37 °C. Protease activity will be determined by a casein digestion method, and one unit of enzyme activity will be defined as the amount of enzyme needed to release acid soluble fragments equivalent to Δ0.001Α ₂₈ ο per minute at 37 °C and pH 7.8. Lipase activity will be assayed, and one unit of enzyme will be the amount of enzyme that hydrolyses 1.0 micro equivalent of fatty acid from a triglyceride in 24 h at pH 7.7 at 37 °C.

[00146] At the end of each experiment, 2 fish of each replicate (6 fish/treatment) will be anaesthetized by tricaine methanesulfonate (MS222) at 250 ppm in water. Blood will drawn near the caudal peduncle of the fish. Blood will be centrifuged at 1000 ^x g for 5 min at room temperature (24 °C) to obtain plasma, which will then be stored at -20 °C for determination of physiological and biochemical parameters (glucose, cholesterol, triglycerides, phosphorus and calcium concentration). These parameters will be analyzed by VetScan Chemistry Analyzer (Scil Animal care company GmBh, Technischer service, Germany).

[00147] PROPHETIC EXAMPLE 14: Hemato-immunological parameter evaluation and Histology assessment.

[00148] RBC and WBC will be counted by a Neubauer's counting chamber haemocytometer. Care will be taken to avoid trapping of air bubbles. The RBC will be counted using a light microscope under high power (40X). The following formula will be used to calculate the number of RBC per mm ³ of the blood sample:

Number of RBC/mm ³ = (N x dilution)/area counted x depth of fluid.

N= Number of cells counted ^'

[00149] The Hb content of blood will be analyzed by Reflotron Hemoglobin test (REF 10744964, Roche diagnostic GmbH, Manheim Germany). Hematocrit will be determined on the basis of sedimentation of blood. Heparinised blood (50 μΐ) will be taken in a hematocrit capillary (Na-heparinised) and centrifuged in the Hematocrit 210 Hettich Centrifuge (Tuttlingen Germany) to obtain hematocrit values.

[00150] From analyses of Hct, Hb and RBC, the following parameters will be calculated:

Mean cell volume, MCV (fL) = (Hematocrit [%] x 1000) ÷ (RBC count

[millions^L]);

Mean cell hemoglobin, MCH (pg) = (Hemoglobin [g/dL] x 10 ÷ (RBC count [in millions^L]) and

Mean cell hemoglobin concentration, MCHC [g/dL] = Hemoglobin [g/dL] ÷ Hematocrit [%].

[00151] A Nobiflow cholesterin (kit lot number 60041889; Hitado Diagnostic system) and Nobiflow triglyceride-GPO (kit lot number 60040710) will be used to determine the plasma cholesterol and triglycerides respectively. The color intensity will be measured spectro- photometrically and it is expected to be proportional to the concentration of cholesterol and triglycerides in the plasma sample.

[00152] Fixed tissues (liver and intestines) will be submitted to dehydration processes following paraffin embedding (Aquagestion). Sections (5 μιη) will be stained with hematoxylin and eosin (H & E) and will be examined under a light microscope. Micrographs will be examined "blind" by the same experienced pathologist. Liver sections will be evaluated for lipid degeneration levels (fatty change) and the integrity of the whole organ. Intestinal morphology will be evaluated according to the following criteria: a) widening and shortening of intestinal folds, 2) loss of supranuclear vacuolization in enterocytes in the intestinal epithelium, 3) widening of central lamina propria within the intestinal folds, and 4) infiltration of (mixed) leukocytes in the lamina propria and submucosa. The occurrence of histological changes for each dietary treatment will be analyzed by Kruskal-Wallis non-parametric Anova with InfoStat v 2009 (Ohio State University, Columbus, OH), with p < 0.05 will be considered significant.

[00153] PROPHETIC EXAMPLE 15: Gene expression analysis.

[00154] Several biological processes will be interlinked and related to intestinal functions including immune- and stress-related processes, protein metabolism, energy and mitochondrial activity, lipid metabolism and transport. Therefore gene expression will be quantified in the intestines, liver and muscles. This analysis will be performed for the fish from the tank experiments.

[00155] The effects of nutritional factors on vertebrate growth and metabolism may be mediated by endocrine regulators, where growth hormone (GH) and insulin-like growth factor I (IGF-I) may play a central role. Growth response will be confirmed in term terms of gene expression, e.g., gene expression patterns viz. growth hormone (GH), insulin-like growth factor I (IGF-I). The stress caused by plant protein in yellow perch will be verified by determining a stress indicator parameter such as a heat shock proteins (HSPs). The generalized stress response at the cellular level may be in part mediated by the actions of a family of proteins known as HSPs. They may be distinguished by their molecular weight and the most extensively characterized of the heat shock proteins is a 70 kDa protein (HSP70) and also the most commonly induced stress protein in response to suboptimal physiological conditions.

[00156] R A isolation: R A will be extracted from 100 mg of tissue by homogenization in 1 ml TRIZol (Invitrogen) using tungsten carbide beads (3 mm, Qiagen) and shaking (300 times per min) following the manufacturer's instructions. The RNA pellet will be washed in 500 μΐ 80% ethanol, air-dried and re-suspended in RNase-free H ₂ 0. The concentration will be determined by spectrophotometry (Nanodrop ND1000, LabTech) and the integrity of the RNA will be determined by electrophoresis (Agilent Bioanalyser 2100). The RNA will then be stored at -80° until required.

[00157] Real-time PCR: The cDNA will be synthesized using 2 μg of total RNA. Real-time PCR will be performed on a number of genes to confirm the microarray analysis results using the same RNA samples. For cDNA synthesis, 2 μg of total RNA will be denatured (70 °C, 3 min) in the presence of 1 μΐ of oligo-dT17 (500 ng/μΐ), left at room temperature for 5 min to allow for annealing, and then stored on ice. The resulting cDNA will be diluted to a final volume of 50 μΐ in RNA/DNA-free water. For real time PCR, 3 μΐ of cDNA will be used as a template with gene specific primers. A 2x iQ SYBR Green supermix will be used for qPCR, which will be performed in a 96-well plate using the DNA Engine OPTICON™ system (MJ Research, Inc., Waltham, MA).

[00158] Statistical analysis: Data from growth performance, nutrient utilization and health parameters will be subjected to a one-way analysis of variance ANOVA and the significance of the differences between means will be tested using Tukey's HSD (Honestly Significant Difference) test (P < 0.05). Values will be expressed as means ± standard deviation. Statistical analysis of the arrays will be performed using the Genespring GX analysis platform (version 9.5; Agilent Technologies, Santa Clara, CA). The qPCR measurements will be analyzed by T-test, performed using R software, with p < 0.05 considered significant.
