A method for producing liver pt that models classic goose liver pt made of goose foie gras. The liver pt does not contain foie gras and only humanely produced raw materials are used. Aqueous jelly is obtained from collagen-containing animal tissue and concentrated into water-soluble jelly. Liquid fat is obtained from animal fat tissue. Raw strained animal liver is obtained by separating solid components. The concentrated aqueous jelly, liquid fat and strained raw liver are mixed, cured and cooked in a container.

The invention relates to the technical field of collagen food. The pure collagen milk powder is prepared by concentrating and drying pure collagen milk, and the pure collagen milk is composed of the following raw materials in parts by weight: 10-80 parts of a pure collagen solution, 0.1-1 part of an emulsion stabilizer, 0.25-5 parts of white granulated sugar, 0.15-3 parts of salt, 0.01-0.5 part of a food flavor, and 20-90 parts of drinking water, wherein the pure collagen solution is a pure collagen solution containing small molecule short-chain peptides.

A process for preparing fish bone powder according to this invention generally comprising at least 4 steps: pre-heating, removing of impurity, drying and milling to derive a calcium-rich bone powder product that contains calcium in the range of 18-22 g/100 g of the fmal product. In addition, the bone powder particle size obtained is less than 100 microns and contains high levels of protein, fat, and essential minerals, such as sodium and phosphorus. The source of bone can be obtained from any fishes, preferably from tuna.

This disclosure provides a high quality protein composition and the processes of making the same. The compositions prepared by filtration according to the instant disclosure may contain higher percentage of branched chain amino acids (BCAA) and/or essential amino acids (EAA). The compositions may have reduced level of sodium and also lighter color than that of the composition before passing through the filtration means.

A method having the following steps: (1) providing a composition containing proteins and amino acids from mucous membranes of animals for slaughter, inorganic salts and water, wherein the sum of the mass of proteins and amino acids in the dry mass of said composition is 30 to 70 weight percent and the mass of inorganic salts in the dry mass of said composition is at least 7.5 weight percent; (2) filtering the composition to obtain a filtrate and a filter cake; (3) cooling the filtrate to a temperature in the range of 15? C. to 15? C. to form a precipitate; (4) separating the resulting precipitate to obtain the liquid phase as product. The disclosure further relates to the products of this method.

The present invention provides methods for extraction of amino acid-rich fractions from keratin-containing biological materials, and to amino acid-rich protein fractions generated by the methods described herein. The methods involve forming a reaction mixture with keratin containing material at a pH of 1.1 to 6.9. The reaction mixture is exposed to an energy source, such as microwaves, sufficient to degrade the keratin. The amino acid mixture which is subsequently extracted is substantially insoluble.
