Moisture is retained in cooked or thawed food by adding to the food an aqueous suspension of animal muscle protein obtained from animal muscle tissue. The aqueous suspension is obtained by mixing comminuted animal muscle tissue with a food grade acid to form an aqueous acidic solution of animal muscle protein. The acidic solution is mixed with a food grade base to precipitate the protein in an aqueous composition. The precipitated protein then is comminuted to form an aqueous suspension of comminuted animal muscle protein.

The present disclosure discloses an aquatic-plant protein combined restructured meat and a preparation method thereof, and belongs to the technical field of processing of foods. According to the present disclosure, a protein combined restructuring processing technology can be summarized as including pretreatment of an aquatic-plant protein, combined restructuring, high-temperature qualitative treatment, and integrated forming. The whole process is green, safe, and environmentally friendly. The protein combined restructured meat prepared contains two proteins including an animal protein and a plant protein, and has a protein content of greater than 20%. While the demands for nutritional dietary proteins are met, the chewability is greater than 1,500 g.Math.mm, and the viscoelasticity is excellent. The meat can be processed in various shapes according to needs, directly heated for eating, or processed into a prepared food, a semi-finished product and the like, so that the product has a large application space.

Provided is a method for producing a composition containing plasmalogen derived from a plasmalogen-containing animal tissue, the method being without significantly decreasing an amount of plasmalogen derived the plasmalogen-containing animal tissue. A method for producing a composition containing plasmalogen derived from an animal tissue, the method comprising: (A) concentrating an alcohol extract of a plasmalogen-containing animal tissue, and (B) after diluting a concentrated product obtained by (A), allowing to stand under refrigeration.

The present invention relates to a method for converting insects into a nutrient stream, such as a puree, an enzymatically hydrolysed puree, a fat fraction and a protein fraction. The invention further relates to the (hydrolysed) puree and to the fractions obtainable by said methods and to their use as a food or feed product or as an ingredient therefore. The invention also relates to a method for converting insect larvae into a composition with anti-oxidant properties. Thus, the invention also relates to a method for converting insect larvae into an antioxidant composition. In addition, the invention relates to a composition with anti-oxidant properties obtainable by said method and to the use of the composition as a health promoting food ingredient or as a feed ingredient.

This application belongs to the field of biotechnology and discloses a method for producing a clam active peptide. The method for producing a clam active peptide comprises cleaning fresh clam meat with water, adding water and homogenizing with a colloid mill to prepare a clam meat slurry; adding water and complex protease for enzymolysis of the clam meat slurry, and heating to inactivate enzyme after the enzymolysis; centrifuging to collect an enzymatic hydrolyzate, capturing the enzymatic hydrolyzate having a molecular weight of lower than 2 KDa through microfiltration-ultrafiltration-nanofiltration membrane filtration, and drying to obtain the clam active peptide. The present disclosure produces a clam active peptide having pure color, outstanding taste, and blood pressure lowering function which is easily absorbed by human body using fresh clam meat as raw material, adopting a complex enzyme-membrane coupling technology through processing techniques such as enzymolysis, membrane separation purification and drying.

Disclosed is a method for manufacturing compounds of interest from at least one mineralized connective tissue, the compounds of interest including at least collagen. The manufacturing method includes a solid/liquid extraction step in which the at least one mineralized connective tissue is mixed with an eluent suitable for extracting the compounds of interest from the at least one mineralized connective tissue to the eluent. This extraction step includes successive operations of adjusting the pH of the eluent, separated by a time interval; each of which pH adjustment operations includes an addition of an acid in the mineralized connective tissue/eluent mixture, to reduce the pH of the eluent until reaching a pH value lower than or equal to 5.5, preferably lower than or equal to 4, preferably ranging from 2 to 4.
