Provided are insect products and methods for producing an insect product comprising solid insect particles. Methods for producing an insect product can include providing a dried cricket powder, providing a dried insect, or grinding wet-grinding, or shearing at least one insect into a paste or powder; adding water or an enzyme to the paste or powder to form a slurry; and filtering the slurry to produce an insect product. Methods for producing a chitin product are also provided that include providing a dried cricket powder or grinding, wet-grinding, or shearing at least one whole insect into a paste or powder; adding water or an enzyme to the paste or powder to form a slurry; and filtering the slurry to produce an insect product comprising chitin.

The present disclosure provides methods and uses for keratin hydrolysates (e.g. feathers hydrolysates).

Disclosed are a fish protein oligopeptide with low allergenicity and slight fishiness, and industrial preparation method and application thereof. The method comprises the following steps: 1) washing fresh fish flesh and/or fish wastes, crushing, and adding water to obtain a mixture; 2) performing thermal denaturation on the mixture to obtain a denaturized protein solution; 3) centrifuging the denaturized protein solution to obtain a precipitate, and adding water into the precipitate and grinding, to obtain a slurry; 4) adjusting the slurry to pH 6-9, and sequentially adding a neutral protease, a papain and an alkaline protease to conduct enzymolysis, and after enzyme inactivation, to obtain an enzymatic hydrolysate; 5) centrifuging the enzymatic hydrolysate, and performing membrane filtration on centrifuged supernatant, to obtain the fish protein oligopeptide with low allergenicity and slight fishiness. The method completely eliminates the allergenicity and fishiness of fish proteins, and prevents release of bitter components.

The present invention relates generally to a method for enzymatic production of food protein ingredients from keratin-containing proteinaceous materials and the resulting compositions. The process includes treating a proteinaceous containing material with an amount of a reducing agent, followed by hydrolysis of the keratin by a proteolytic enzyme to efficiently and economically convert a keratinaceous protein source into a palatable, highly digestible protein food product.

The present invention provides marine protein hydrolysates for use in pharmaceuticals, nutraceuticals functional foods, foods, beverages, and animal feeds, as well as methods for making marine protein hydrolysates.

To provide a feed that does not pollute rearing water, improves the immunity activity of leptocephalus larvae, is capable of directly feeding eel leptocephalus, and is capable of effectively inducing the growth of said larvae into glass eels. This micro-encapsulated aquaculture feed includes: an oil phase 11 having an oil-soluble nutrient component; a water phase 13 which is present inside the oil phase 11, and which includes a water-soluble nutrient component; and a film 15 which includes the oil phase 11 and the water phase 13. The water-soluble nutrient component includes at least one hydrolysate from among hydrolysates of amino acids, oligopeptides, and proteins.

The invention relates to healthy food compositions with a gel or foam texture that have antioxidant properties, are rich in proteins, low-fat, lactose- and casein-free and easy-to-chew, comprising a neutral-flavored egg hydrolysate as a basic ingredient. These compositions are presented as an alternative to sweet and salty dishes using dairy products as a base because they have similar flavor, appearance and texture characteristics. These compositions are also presented as new foods that are particularly indicated for being consumed by people who are lactose intolerant or who have obesity issues.

The present invention refers to a method for obtaining dehydrated food with a high content of hydrolyzed proteins from fish stickwater; for this purpose, the insoluble solids and fat traces are separated the stickwater, which then undergoes a process of demineralization by electrodialysis, in order to then adjust its temperature and pH to proceed with the enzymatic hydrolysis that allows to fractionate the protein, which is then concentrated and spray dried, and then the dried product is finally conveniently packaged.

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.
