(Modified) rice endosperm protein is used as novel protective hydrocolloid for active ingredients, especially fat-soluble active ingredients and/or colorants. Included are compositions comprising (modified) rice endosperm protein and at least one active ingredient and to their manufacture, as well as to the (modified) rice endosperm protein itself and its manufacture. These compositions are used for the enrichment, fortification and/or coloration of food, beverages, animal feed, personal care or pharmaceutical compositions, and to food, beverages, animal feed, personal care and pharmaceutical compositions containing such a (modified) rice endosperm protein and such a composition, respectively.
摘要:
The present invention contemplates the creation of a low fluoride oil processed from a phospholipid-protein complex (PPC) formed immediately upon a crustacean (i.e., for example, krill) catch. The process comprises disintegrating the crustaceans into smaller particles, adding water, heating the result, adding enzyme(s) to hydrolyze the disintegrated material, deactivating the enzyme(s), removing solids from the enzymatically processed material to reduce fluoride content of the material, separating and drying the PPC material. Then, using extraction with supercritical CO2 and ethanol as solvents, inter alia krill oil is separated from the PPC. In the extraction the krill oil can be separated almost wholly from the feed material. The products have low fluoride content. The manufacturing costs in the extraction process are relatively low.

The present invention provides protein hydrolysate compositions, processes for making protein hydrolysate compositions, and food products comprising protein hydrolysate compositions. The protein hydrolysate compositions generally comprise polypeptide fragments having primarily either an arginine residue or a lysine residue at each carboxyl terminus.

Provided are a seasoning that contains deep and rich flavor of ingredients mainly composed of a large amount of glutamic acid, and a method for producing the seasoning. The glutamic acid content in a glutamic acid containing seasoning liquid thus produced is not lowered even after long-term storage thereof. Herein, a protein raw material such as wheat gluten, defatted soybeans, and an extracted residue of dried and fermented fish shavings is enzymatically decomposed by the liquid koji. In that step, a zinc containing compound or zinc yeast is added to the mixture of the raw materials such that the zinc concentration is set in the range from 5 ppm or more to 700 ppm or less as a conversion amount of pure zinc. This procedure facilitates the enzymatic decomposition to produce an excellently flavored seasoning liquid or powder including a large amount of glutamic acid.
摘要:
The present invention relates to a method for the manufacture of a composition comprising proteins and fats, said method providing a simple and non-expensive way of obtaining fat-containing proteinaceous products of high nutritional value that are easy to handle and at the same time possess high stability towards coalescence and oxidation. More particularly, a method is provided for the manufacture of a composition comprising protein and fat in disperse form, the method comprising the following steps: (i) providing a suspension having a pH value higher than 7.0, said suspension comprising water, proteinaceous material, fat, and optionally alkali; (ii) incubating the suspension from (i) at a temperature in the interval 50-150° C.; (iii) homogenizing the suspension from (ii) to form a dispersion; and (iv), if desired, subjecting the dispersion from (iii) to a subsequent treatment; wherein the proteinaceous material in step (i) comprises vegetable-based proteinaceous material, and/or yeast-based proteinaceous material; wherein the suspension in step (i) comprises at least 5% fat by weight of dry matter. The current invention also relates to the compositions obtained by the method and to compositions obtainable by the method of the invention and, further, to the use of these compositions.
摘要:
The present invention discloses a method for producing wheat glutamine peptide using wheat gluten powder as raw material, belonging to the fields of food and biotechnology. The method includes the steps of: performing enzymolysis in two steps using Alcalase and papain with the wheat gluten powder as raw material, to obtain the wheat glutamine peptide with components with molecular weight of less than 1000 Da being more than 90%, characteristic glutamine peptide segment glutamine-arginine-glutamine (Gln-Arg-Gln, QRQ) content being more than 2.0% and glutamine content being up to 23.54% by treating the enzymatic hydrolysate by centrifugation, ultrafiltration, concentration, spray drying, etc. The produced glutamine peptide can be used as functional nutrition composition ingredient in the development and production of ordinary foods, health foods and medicines.
摘要:
Methods are described for treating a whey protein mixture to increase a relative concentration of α-lactalbumin protein in the mixture. The methods may include the step of adjusting a temperature of the whey protein mixture to about 10° C. or less, and adjusting the pH of the mixture to greater than 7. The may further include adding a protease enzyme to the whey protein mixture that selectively hydrolyzes β-lactoglobulin protein in the mixture. The activity of the protease enzyme in the hydrolyzed whey protein mixture may be terminated before a substantial portion of the α-lactalbumin protein has been hydrolyzed by the enzyme. In some instances, the whey protein mixture may also include glycomacropeptides that are selectively hydrolyzed with the β-lactoglobulin protein. The β-lactoglobulin and glycomacropeptide hydrolysates may be separated to produce an enhanced α-lactalbumin protein composition for infant formula, among other products.

摘要:
Partially deamidated rice endosperm protein or rice endosperm protein which is partially conjugated with mono-, di-, oligo- or polysaccharides is used as novel protective hydrocolloid for fat-soluble active ingredients and/or fat-soluble colorants. The present invention further includes compositions comprising that rice endosperm protein and at least one fat-soluble active ingredient/colorant, as well as their manufacture, that rice endosperm protein itself and its manufacture. These compositions are used for the enrichment, fortification and/or coloration of food, beverages, animal feed, personal care or pharmaceutical compositions. The present invention is directed to theses uses and to food, beverages, animal feed, personal care and pharmaceutical compositions containing such a rice endosperm protein and such a composition, respectively.
