The present invention discloses a method for efficiently and mildly reducing ovalbumin allergenicity. The present invention promotes the exposure of the ovalbumin allergenic site to the molecular surface by repeated freezing and thawing pretreatment, and combines transglycosylase and trypsinase for synergistic treatment to reduce the ovalbumin sugar chain and epitope to achieve the purpose of significantly reducing the allergenicity of ovalbumin and egg foods. Compared with other traditional methods such as high temperature and high pressure and other physical means to reduce egg allergenicity, the method significantly improves the specificity and effectiveness of egg desensitization, and minimizes the damage to the nutrition and quality of egg proteins, and is an efficient and mild egg desensitization method. The method has the prospects of being applied to the industrial development of low-allergenicity egg products.

A method of producing a protein phospholipid complex from a crustacean catch including protein is claimed where hydrolysis occurs without substantially denaturing the protein from the crustacean catch. A method of producing a stable protein phospholipid emulsion from a crustacean catch is also claimed. A method of producing crustacean oil is claimed where the oil is separated from the hydrolyzed crustacean catch. Other methods of producing a protein phospholipid complex are claimed which relate to not removing the shell, removing the shell, and removing then adding back the shell to form the protein phospholipid complex.

The aspects presented herein provide methods and compositions for the reduction or suppression of marine protein hydrolysate malodor by employing rice extract and/or a solid acid, preferably selected from malic acid, tartaric acid and citric acid.

The invention relates to a method for producing highly digestible, partly hydrolyzed keratinaceous material, preferably from feathers, hair, wool, hooves or nails, comprising the steps of (1) hydrolyzing keratinaceous material in the presence of water, in a hydrolyzer with heat and at a pressure between about 2 bar and about 100 bar to obtain a partly hydrolyzed keratinaceous material; (2) pre-drying the partly hydrolyzed keratinaceous material of step (1) to obtain a semi-dried partly hydrolyzed keratinaceous material having a solids content of about 50 wt % or higher, preferably between 60-85 wt %; and (3) concurrently drying and grinding the semi-dried partly hydrolyzed keratinaceous material of step (2) in an air turbulence mill, at about atmospheric pressure to obtain dried partly hydrolyzed keratinaceous material; wherein preferably steps (2) and (3) are carried out such that the drop in pepsin and/or ileal digestibility caused by steps (2) and (3) is less than 10%, and/or the pepsin and ileal digestibility of the dried partly hydrolyzed keratinaceous material is higher than respectively 75% and 80%; wherein the resultant dried partly hydrolyzed keratinaceous material comprises at least partly insoluble material, and wherein the average particle size of the dried partly hydrolyzed keratinaceous material (d50) leaving the air turbulence mill is between 20 m and 0.7 mm and the d90 is below 1 mm as measured with laser diffraction using a dry powder Beckman Coulter particle size analyzer.

The present invention provides a colostrum hydrolysate having a content of L-tryptophan improved by hydrolysis of colostrum using a proteolytic enzyme, a method for production of the same, and a whitening composition including the above hydrolysate as an active ingredient. The colostrum hydrolysate according to the present invention has an advantage in that low molecular weight components such as peptide, L-tryptophan, etc. are generated by hydrolyzing protein contained in a colostrum extract using hydrolase, thereby enabling easy absorption thereof to the human body. The colostrum hydrolysate may be usefully utilized in cosmetics, foods, medicines, feed industry and the like.

A method is provided for making food product ingredients from indigestible keratinous protein-containing material. The methods generally include adding an amount of cereal bran and/or one or more reducing sugars to the keratinous protein-containing material to provide a mixture and hydrolyzing the mixture. The methods generate fewer unpleasant odors, and food product ingredients produced by the method can similarly benefit. Antioxidants may also be added, and in such embodiments, even fewer off odors may be generated and/or palatability may be enhanced.
