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.

Processes for preparing and purifying protein from plant material, and compositions and uses comprising the same, are provided.

The present invention addresses the problem of providing a method for improving a texture of a protein. By allowing a protein deamidase to act on a substrate protein, a feeling of the protein on a tongue can be smoothened, and the texture thereof can be improved.

The invention relates to a method for preparing nutrients from insects, comprising the following steps: a) grinding the insects so as to obtain a ground material; b) subjecting the ground material to enzymatic hydrolysis so as to obtain a hydrolyzed ground material; c) pressing the hydrolyzed ground material so as to obtain a chitin-enriched solid fraction and a liquid fraction; and d) subjecting the liquid fraction to a physical separation so as to obtain an aqueous protein fraction and an oil fraction.

The present invention relates to a method for converting insects into nutrient streams, 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.

A turkey collagen hydrolysate composition is prepared from turkey collagen sources, wherein the composition has: a protein concentration of from about 80 wt % to 100 wt %; a protein molecular weight distribution wherein from about 80% to 100% of the protein in the turkey collagen hydrolysate composition has a molecular weight of from about 500 to about 15,000 Daltons; a protein solubility of from about 97% to 100% at a pH selected from the group consisting of pH 7.0, pH 3.4, pH 5, and all of pH 7.0, pH 5, and pH 3.4; and a protein amino acid content of 3 to 25 glycine (g/100 g sample), 0.5 to 15 hydroxyproline (g/100 g sample), 1 to 18 proline (g/100 g sample), 0.02 to 4 taurine (g/100 g sample), and 0.05 to 3 tryptophan (g/100 g sample). Methods of preparing turkey collagen hydrolysate compositions are described.
