SACCHARIDES AND SACCHARIDE COMPOSITIONS AND MIXTURES

RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application No. 62/052,913, filed September 19, 2014; and U.S. Provisional Application 62/055,349, filed September 25, 2014.

FIELD OF THE INVENTION

The present invention relates generally to compositions including saccharides and mixtures of saccharides and related compounds. The present invention further generally relates to methods for producing the compositions described herein. The present invention also provides methods for using such compositions, e.g., as health care products, or as a sweetener in a product such as a beverage sweetener or syrup.

BACKGROUND OF THE INVENTION

Xylose is a natural sugar that is found (in polymeric form) in some woody materials such as straw, birch trees, pecan shells, cottonseed hulls, and corncobs. Xylose tastes sweet, and can inhibit the absorption of other sugars in the body. On the glycemic index, which measures the rate of the absorption of sugar by the body, sugar is a 100 while xylose is only a 7. Moreover, xylose does not contribute to tooth decay. Xylose is safe for use in foods and has additional desirable properties including beneficial antibacterial and antifungal activity.

However, xylose can be expensive to produce, making it more difficult to incorporate into products such as food and beverage products. Artificial sweeteners and genetically modified foods can destroy the body' s flora and can encourage the wrong type of bacterial overgrowth, resulting in incorrect physiological responses in the human body, such as in your GI tract, which can lead to glucose intolerance (Nature 514, 191-186, October 2014).

SUMMARY OF THE INVENTION

Applicant has discovered that health benefits are increased and are associated with the proper use of compositions of sugars and/or sweeteners and related compounds. Health benefits are improved by consideration of the physiology of the use of sugars and sweeteners and/or related compounds, e.g., sugar alcohols. Applicant has further discovered that, for example, both corn and cane sugars have been manufactured as only 6-carbon products or disaccharides of 6-carbon sugars even though the corn and sugar cane plants themselves carry both 6-carbon sugars and 5-carbon sugars (in polymeric form). It is a concern of the applicant that the benefit of using both 5- and 6-carbon sugars in the proper ratio increases good health and nutritional well-being.

While it is generally understood that the consumption of unprocessed or lightly processed foods, such as whole, raw, unpeeled fruits and vegetables, is associated with substantial health benefits, such as a reduction in cardiovascular disease, lowering of blood pressure, improved brain activity, reduction in incidence of cancer, improved intestinal health and improved vision, it is generally poorly understood as why this is the case. Applicant believes that such benefits, at least in part, are associated with the fact that such whole foods have a more balanced and natural carbohydrate content in terms of simple sugars, e.g., glucose, mannose, galactose and xylose and polymeric sugars, e.g., cellulose and hemicellulose.

Processed foods generally enrich foods in unnatural ratios of sugars. Perturbing the natural ratios of sugars or enriching one or more sugars can have significant health consequences, including many that are non-beneficial.

Applicant believes that although only small amounts of hemicellulose is broken down to simple sugars, e.g., xylose, mannose, galactose and glucose, along the digestive tract, even small amounts of these sugars not normally found in processed foods can induce positive health benefits. Applicant suggests that the breakdown of hemicellulose is a in the digestive tract is an example of a natural force action as such breakdown naturally stimulates various biological processes in those organisms in the digestive tract that would not be so stimulated if not for the presence of the described hemicellulose sugars. Such stimulation can allow for the uptake of more nutrients, such as micronutrients, and produce health benefits in the body.

Applicant has further discovered cost efficient ways to make compositions that include small sugars, such as xylose. Described herein are products and compositions that include xylose. Exemplary products and compositions include syrups and beverage products comprising xylose. In some embodiments, the compositions include xylose and one of more of any saccharide, such as a mono-, di-, tri- or oligosaccharide, or an associated sugar alcohol. The saccharides can be in any stereoisomeric form. The saccharides include 3, 4, 5, 6, or more e.g., 7, 8 or more, e.g., 9-16 carbon atoms. Exemplary saccharides include glyceraldehyde, dihydroxyacetone, erythose, ribose, ribulose, arabinose, glucose, fructose, manose, galactose, corn syrup, high fructose corn syrup, sedoheptulose, sucrose, maltose, lactose, and cellobiose. In some embodiments the composition includes xylose and glucose. In other embodiments, the compositions include xylose and glucose, along with other saccharides, such as galactose, sucrose, arabinose, mannose, fructose and oligomeric saccharides, such as di-, tri-, tetra-, penta- and hexasaccharides. In particular embodiments, the composition includes greater than 75 percent by weight glucose plus xylose, e.g., greater than 80, 85, 90, or greater than 95 percent by weight glucose plus xylose.

Advantages can include one or more of the following benefits. Low glycemic index compositions are provided. The deleterious effects related to the overuse of some sugars, such as glucose, sucrose, fructose, corn syrup, corn sugar and high fructose corn syrup (HFCS), can be reduced, even with the addition of relatively small amounts of xylose. The deleterious effects related to the use or overuse of sugar substitutes, such as stevia, aspartame, sucralose, neotame, acesulfame potassium (Ace-K), saccharin, advantame and cyclamates, can be reduced. The compositions can be useful for those with diabetes and can be useful for reducing obesity. The compositions can be blended with sugar substitutes and sugar alcohols. Unique mouth-feel products can be produced with consumer appeal. Synergistically sweet

compositions can be provided with blends of xylose and any compound described herein.

Compositions can be provided that have a longer shelf life and that have a lower tendency to be contaminated with microorganisms. Non-crystallizing compositions can be provided.

Compositions can be provided that are useful in cooking and are easier to brown during cooking. The compositions can have oral health benefits, such as the reduction of dental caries and gingivitis. The compositions can be useful in fighting cancer. The compositions can be useful in balancing gut bacteria, which can lead to improved health, better digestion, improved memory and mental health. The compositions can reduce risk of stroke, diabetes, obesity, metabolic disease, cardiovascular disease and high blood pressure. The compositions can also improve vision.

For urban areas, the best potential plant biomass feedstock includes yard waste (e.g., grass clippings, leaves, tree clippings, and brush) and vegetable processing waste.

The term "biomass degrading enzymes", as used herein, refers to enzymes that break down components of the biomass matter described herein into intermediates or final products. For example, biomass-degrading enzymes include at least ligninases,

endoglucancases, cellobiases, xylanases, and cellobiohydrolases. Biomass-degrading enzymes are produced by a wide variety of microorganisms, and can be isolated from the

microorganisms, such as T. reesei.

The term "cellobiase", as used herein, refers to an enzyme that catalyzes the hydrolysis of a dimer, trimer, tetramer, pentamer, hexamer, heptamer, octamer, or an oligomer of glucose, or an oligomer of glucose and xylose, to glucose and/or xylose. For example, the cellobiase is beta-glucosidase, which catalyzes beta- 1,4 bonds in cellobiose to release two glucose molecules.

The term "cellobiase activity", as used herein, refers to activity of a category of cellulases that catalyze the hydrolysis of cellobiose to glucose, e.g., catalyzes the hydrolysis of beta-D-glucose residues to release beta-D-glucose. Cellobiase activity can be determined according to the assays described herein, e.g., in Example 6. One unit of cellobiase activity can be defined as [glucose] g/L / [Cel3a] g/L / 30 minutes.

The term "cellobiohydrolase" as used herein, refers to an enzyme that hydrolyzes glycosidic bonds in cellulose. For example, the cellobiohydrolase is 1 ,4-beta-D-glucan cellobiohydrolase, which catalyzes the hydrolysis of 1,4-beta-D-glucosidic linkages in cellulose, cellooligosaccharides, or any beta- 1,4-linked glucose containing polymer, releasing oligosaccharides from the polymer chain.

The term "endoglucanase" as used herein, refers to an enzyme that catalyzes the hydrolysis of internal -1,4 glucosidic bonds of cellulose. For example, the endoglucanase is endo- 1 ,4-(l ,3; 1 ,4)-beta-D-glucan 4-glucanohydrolase, which catalyses endohydrolysis of 1,4- beta-D-glycosidic linkages in cellulose, cellulose derivatives (such as carboxymethyl cellulose and hydroxyethyl cellulose), lichenan, beta- 1,4 bonds in mixed beta- 1, 3 glucans such as cereal beta-D-glucans or xyloglucans, and other plant material containing cellulosic components.

The term "ligninase" as used herein, refers to an enzyme that catalyzes the breakdown of lignin, commonly found in the cell walls of plants, such as by an oxidation reaction.

METHODS OF MAKING

A composition or product described herein can be made using a process described herein. For example, a composition described herein can be made by converting or processing a biomass into a composition comprising xylose. In some embodiments, the composition comprises xylose and glucose. Exemplary methods include those described in

WO2014/138553, which is incorporated by reference herein.

Methods for converting a biomass to products, such as sugar products, are known in the art, for example, as described in US Patent Application 2014/0011258, the contents of which are incorporated by reference in its entirety. Briefly, a biomass is optimally pretreated, e.g., to reduce the recalcitrance, and saccharified by a saccharification process that involves incubating the treated biomass with biomass-degrading, or cellulolytic, enzymes to produce sugars (e.g., glucose and/or xylose). The sugar products can then be further processed to produce a final product, e.g., by fermentation or distillation.

Using the processes described herein, the biomass material can be converted in a cost efficient manner to a composition described herein. Biomass

The biomass may include, but is not limited to starchy materials, sugar cane, agricultural waste, paper, paper products, paper waste, paper pulp, pigmented papers, loaded papers, coated papers, filled papers, magazines, printed matter, printer paper, polycoated paper, card stock, cardboard, paperboard, cotton, wood, particle board, forestry wastes, sawdust, aspen wood, wood chips, grasses, switchgrass, miscanthus, cord grass, reed canary grass, grain residues, rice hulls, oat hulls, wheat chaff, barley hulls, agricultural waste, silage, canola straw, wheat straw, barley straw, oat straw, rice straw, jute, hemp, flax, bamboo, sisal, abaca, corn cobs, corn stover, soybean stover, corn fiber, alfalfa, hay, coconut hair, sugar processing residues, bagasse, beet pulp, agave bagasse, algae, seaweed, plankton manure, sewage, offal, agricultural or industrial waste, arracacha, buckwheat, banana, barley, cassava, kudzu, oca, sago, sorghum, potato, sweet potato, taro, yams, beans, favas, lentils, peas, or mixtures of any of these. In a preferred embodiment, the biomass comprises agriculture waste, such as corn cobs, e.g., corn stover. In another embodiment, the biomass comprises grasses.

In one embodiment, the biomass is treated prior to contact with the compositions described herein. For example, the biomass is treated to reduce the recalcitrance of the biomass, to reduce its bulk density, and/or increase its surface area. Suitable biomass treatment process may include, but are not limited to: bombardment with electrons, sonication, oxidation, pyrolysis, steam explosion, chemical treatment, mechanical treatment, and freeze grinding. Preferably, the treatment method is bombardment with electrons.

In some embodiments, electron bombardment is performed until the biomass receives a total dose of at least 0.5 Mrad, e.g. at least 5, 10, 20, 30, or at least 40 Mrad. In some embodiments, the treatment is performed until the biomass receives a dose a of from about 0.5 Mrad to about 150 Mrad, about 1 Mrad to about 100 Mrad, about 5 Mrad to about 75 Mrad, about 2 Mrad to about 75 Mrad, about 10 Mrad to about 50 Mrad, e.g., about 5 Mrad to about 50 Mrad, about 20 Mrad to about 40 Mrad, about 10 Mrad to about 35 Mrad, or from about 20 Mrad to about 30 Mrad. In some implementations, a total dose of 25 to 35 Mrad is preferred, applied ideally over a couple of seconds, e.g., at 5 Mrad/pass with each pass being applied for about one second. Applying a dose of greater than 7 to 9 Mrad/pass can in some cases cause thermal degradation of the feedstock material. The biomass material (e.g., plant biomass, animal biomass, paper, and municipal waste biomass) can be used as feedstock to produce useful intermediates and products such as organic acids, salts of organic acids, anhydrides, esters of organic acids and fuels, e.g., fuels for internal combustion engines or feedstocks for fuel cells. Systems and processes are described herein that can use as feedstock cellulosic and/or lignocellulosic materials that are readily available, but often can be difficult to process, e.g., municipal waste streams and waste paper streams, such as streams that include newspaper, kraft paper, corrugated paper or mixtures of these.

In order to convert the feedstock to a form that can be readily processed, the glucan- or xylan-containing cellulose in the feedstock can be hydrolyzed to low molecular weight carbohydrates, such as sugars, by a saccharifying agent, e.g., an enzyme or acid, a process referred to as saccharification. The low molecular weight carbohydrates can then be used, for example, in an existing manufacturing plant, such as a single cell protein plant, an enzyme manufacturing plant, or a fuel plant, e.g., an ethanol manufacturing facility.

The feedstock can be hydrolyzed using an enzyme, e.g., by combining the materials and the enzyme in a solvent, e.g., in an aqueous solution. The enzymes can be made/induced according to the methods described herein.

Specifically, the enzymes can be supplied by organisms that are capable of breaking down biomass (such as the cellulose and/or the lignin portions of the biomass), or that contain or manufacture various cellulolytic enzymes (cellulases), ligninases or various small molecule biomass-degrading metabolites. These enzymes may be a complex of enzymes that act synergistically to degrade crystalline cellulose or the lignin portions of biomass. Examples of cellulolytic enzymes include: endoglucanases, cellobiohydrolases, and cellobiases (beta- glucosidases).

During saccharification a cellulosic substrate can be initially hydrolyzed by endoglucanases at random locations producing oligomeric intermediates. These intermediates are then substrates for exo-splitting glucanases such as cellobiohydrolase to produce cellobiose from the ends of the cellulose polymer. Cellobiose is a water-soluble 1,4-linked dimer of glucose. Finally, cellobiase cleaves cellobiose to yield glucose. The efficiency (e.g., time to hydrolyze and/or completeness of hydrolysis) of this process depends on the recalcitrance of the cellulosic material. Saccharification

The reduced-recalcitrance biomass is treated with the biomass-degrading enzymes discussed above, generally by combining the reduced-recalcitrance biomass and the biomass- degrading enzymes in a fluid medium, e.g., an aqueous solution. In some cases, the feedstock is boiled, steeped, or cooked in hot water prior to saccharification, as described in U.S. Pat. App. Pub. 2012/0100577 Al by Medoff and Masterman, published on Apr. 26, 2012, the entire contents of which are incorporated herein.

Provided herein are mixtures of enzymes that are capable of degrading the biomass, e.g., an enzyme mixture of biomass-degrading enzymes, for use in the saccharification process described herein.

The saccharification process can be partially or completely performed in a tank (e.g., a tank having a volume of at least 4000, 40,000, or 500,000 L) in a manufacturing plant, and/or can be partially or completely performed in transit, e.g., in a rail car, tanker truck, or in a supertanker or the hold of a ship. The time required for complete saccharification will depend on the process conditions and the biomass material and enzyme used. If saccharification is performed in a manufacturing plant under controlled conditions, the cellulose may be substantially entirely converted to sugar, e.g., glucose in about 12-96 hours. If saccharification is performed partially or completely in transit, saccharification may take longer.

In a preferred embodiment, the saccharification reaction occurs at a pH optimal for the enzymatic reactions to occur, e.g., at the pH optimal for the activity of the biomass- degrading enzymes. Preferably, the pH of the saccharification reaction is at pH 4-4.5. In a preferred embodiment, the saccharification reaction occurs at a temperature optimal for the enzymatic reactions to occur, e.g., at the temperature optimal for the activity of the biomass- degrading enzymes. Preferably, the temperature of the saccharification reaction is at 42°C - 52°C.

It is generally preferred that the tank contents be mixed during saccharification, e.g., using jet mixing as described in International App. No. PCT/US2010/035331, filed May 18, 2010, which was published in English as WO 2010/135380 and designated the United States, the full disclosure of which is incorporated by reference herein. The addition of surfactants can enhance the rate of saccharification. Examples of surfactants include non-ionic surfactants, such as a Tween® 20 or Tween® 80 polyethylene glycol surfactants, ionic surfactants, or amphoteric surfactants.

It is generally preferred that the concentration of the sugar solution resulting from saccharification be relatively high, e.g., greater than 40%, or greater than 50, 60, 70, 80, 90 or even greater than 95% by weight. Water may be removed, e.g., by evaporation, to increase the concentration of the sugar solution. This reduces the volume to be shipped, and also inhibits microbial growth in the solution.

Alternatively, sugar solutions of lower concentrations may be used, in which case it may be desirable to add an antimicrobial additive, e.g., a broad spectrum antibiotic, in a low concentration, e.g., 50 to 150 ppm. Other suitable antibiotics include amphotericin B, ampicillin, chloramphenicol, ciprofloxacin, gentamicin, hygromycin B, kanamycin, neomycin, penicillin, puromycin, streptomycin. Antibiotics will inhibit growth of microorganisms during transport and storage, and can be used at appropriate concentrations, e.g., between 15 and 1000 ppm by weight, e.g., between 25 and 500 ppm, or between 50 and 150 ppm. If desired, an antibiotic can be included even if the sugar concentration is relatively high. Alternatively, other additives with anti-microbial of preservative properties may be used. Preferably the

antimicrobial additive(s) are food-grade.

A relatively high concentration solution can be obtained by limiting the amount of water added to the biomass material with the enzyme. The concentration can be controlled, e.g., by controlling how much saccharification takes place. For example, concentration can be increased by adding more biomass material to the solution. In order to keep the sugar that is being produced in solution, a surfactant can be added, e.g., one of those discussed above.

Solubility can also be increased by increasing the temperature of the solution. For example, the solution can be maintained at a temperature of 40-50° C, 60-80° C, or even higher.

In the processes described herein, for example after saccharification, xylose (e.g., glucose and xylose) can be isolated. For example, xylose can be isolated by precipitation, crystallization, chromatograp y (e.g., simulated moving bed chromatography, high pressure chromatography), centrifiigation, extraction, any other isolation method known in the art, and combinations thereof. In an embodiment, the isolate product includes xylose or a mixture of glucose. Once Isolated, the xylose containing composition, or xylose and glucose containing composition can be formulated into a product described herein such as a beverage or a syrup.
