DESCRIPTION

SOUR CHERRY EXTRACT WITH ANTIOXIDANT CAPACITY INCREASED BY 1.5 TIMES

AND PRODUCTION METHOD THEREOF

Technical Field

The invention relates to an extract produced from sour cherry concentrate with fermentation method.

The invention particularly relates to low sugar and even sugar-free sour cherry extract with antioxidant capacity increased 1.5 times (in liquid and powder forms).

Prior Art

Sour cherry is a type of fruit from rosaceae family that resembles cherry and has a sour taste compared to cherry. The sour cherry concentrates or extracts consumed in the prior art are analyzed for total phenolic substance content. Total Phenolic Substance analysis is measured by employing the method obtained from modification of Slinkard-Singleton procedure using Folin-ciocalteu reagent (1) and accordingly total phenolic substance of the liquid extract is 50.00±1.5 mg GEs/ g extract (GEs, Gallic acid equivalent) or ORAC (Oxygen Radical Absorbance Capacity) antioxidant capacity determination provides an ORAC value of 30000 pmolar TROLOX/100 g. It is a known fact that the sugar proportions for the concentrates are 10.5-12% glucose, 31-35% fructose by weight. Encapsulation of the sour cherry concentrate is almost impossible due to such high sugar content of the concentrates.

The sour cherry extracts obtained from the sour cherry in the prior art cannot be used by the diabetics and cannot be encapsulated due to high sugar content thereof. Moreover, high sugar rate might lead to undesired consequences such as adhesion, agglomeration, fermentation, etc. at the end product to be used.

Fermentation or zymolysis is chemical decomposition of a substance by means of bacteria, fungi and other microorganisms, generally by supplying heating and foaming. In the prior art, various fruits are subjected to fermentation in order to increase their total phenolic substance values.

Patent applications No. CA2688661, EP2132994 and US8257761 are some of the applications encountered during the literature studies. In said applications fermentation is performed on fruit (pomegranate, apple) juice or fruit. Saccharomyces boulardii yeast and minimum one lactic acid basil are used in said fermentation. The end product contains up to 2% glucose or glucose-fructose mixture.

In conclusion, the technique of the prior art mentioned above fails to provide solutions to the existing problems, thus necessitates an improvement in the technical field related to sour cherry concentrates.

Objective of the Invention

The present invention relates to sour cherry extract with antioxidant capacity increased by 1.5 times and production method thereof which meets the aforementioned requirements, eliminates all disadvantages and introduces some additional advantages.

The main objective of the invention is that it is an extract produced with fermentation method from sour cherry concentrate. In this manner, the total phenolic substance content thereof is 1.5 times richer than any standard concentrate or extract. Therefore, antioxidant capacity is also 1.5 times higher.

An objective of the invention is that, as a result of the antioxidant capacity determination, ORAC value is 69000 pmolar TROLOX/100 g (encapsulated sour cherry extract 65000 pmolar TROLOX/100 g); while total phenolic substance is 155.2±2.5 mg GEs/ g extract for liquid extract; 93.6±2.5 mg GEs g extract for encapsulated extract.

Another objective of the invention is that the extract contains 0% fructose, 0-2% glucose by weight as sugar proportions; therefore the extract can be encapsulated. The value of the encapsulated product with respect to antioxidant capacity has the same level and ORAC value is 65000 molar TROLOX/100 g. In this manner, sour cherry extract with increased antioxidant capacity can be produced as encapsulated, that is to say, powder products.

Production method:

For sour cherry extract in liquid form:

• The sour cherry concentrate at 65 °Brix value is transferred to a tank for performing the reaction,

• Then, water at ambient temperature (20-25°C) is added thereto,

• Then, yeast is added thereto; the tank in which reaction will occur is covered in such manner to allow ingress of air and the temperature is set as fixed at 25 °C,

• The fermentation starts on the obtained mixture,

The "Brix value of the mixture is measured minimum twice every day using a refractometer. Fermentation process is completed in 5-7 days on average. During this period, fermentation must be checked frequently and fermentation must be ceased when reaching 10-12 "Brix.

• The mixture is passed through the filter press,

The clear liquid obtained is evaporated up to 65-67 °Brix under suitable vacuum and at a temperature not exceeding 40°C; the liquid product must be minimum 65 °Brix for microbiological adequacy.

• Liquid sour cherry extract at 65-67 "Brix is packed.

For encapsulated sour cherry extract (powder form):

• The sour cherry concentrate at 65 "Brix value is transferred to a tank for performing the reaction,

• Then, water at ambient temperature (20-25°C) is added thereto,

• Then, yeast is added thereto; the tank in which reaction will occur is covered in such manner to allow ingress of air and the temperature is set as fixed at 25 °C,

• The fermentation starts on the obtained mixture,

The "Brix value of the mixture is measured minimum twice every day using a refractometer. Fermentation process is completed in 5-7 days on average.

During this period, fermentation must be checked frequently and fermentation must be ceased when reaching 10-12 °Brix.

• The mixture is passed through the filter press,

• The clear liquid obtained is evaporated up to 40 "Brix under suitable vacuum and at a temperature not exceeding 40°C,

• The fluid at 40 °Brix value is transferred to the slurry tank,

• It is encapsulated by means of a high-speed mixer by adding water and maltodextrine thereto,

• The slurry is slowly fed to spray dryer for dry spraying at low temperature (inlet temperature; 170 °C),

• The powder sour cherry extract is encapsulated and packed.

Points to consider during practice of the aforementioned production method:

• The fermentation temperature must not exceed 20-25°C,

• The °Brix value must be measured constantly during fermentation and the fermentation must be ceased upon reaching 10-12 Brix,

• The fermentation must last for max. 7 days,

• The evaporation temperature must not exceed 35-40°C, • If spray dryer will be used, then the inlet temperature must not be higher than around 170-175°C,

• The mixture must be filtered at 0.5-1 micron filters after fermentation, thus the yeast is removed from the medium.

The sour cherry extracts of the invention (in liquid or powder form) is used in beverages, cakes, fruit yogurts and dairy products as chocolate filler.
