A method for recycling protein waste and producing an edible product for animal consumption comprises grinding animal carcasses or parts thereof and thereafter acidifying the waste. The acidified waste may then be emulsified, followed by a heat shock and then fed to animals. Alternatively, a second emulsification may be employed prior to being used for animal consumption. The emulsified products may be provided to animals as a liquid, or dried to a paste prior to use.

Shown here is a process for preparing a concentrated liquid composition (such as a broth) from poultry or other meat sources without the use of any enzymes. The resultant composition may have high content of solids but are pumpable or pourable and have relatively long shelf life at room temperature. Also shown are methods of extracting proteins from raw poultry or other meat sources at relatively low temperatures. Methods of making a high protein curd is also disclosed.

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 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 present invention relates to the use of turbine mixing during enzymatic hydrolysis of aquatic protein from species such as fish, aquatic mammals, crustaceans and/or mollusks, to obtain high quality aquatic protein hydrolysates, having very low oxidation, improved organoleptic profile and improved biological activity of interest, for human consumption and cosmetics. The turbine mixing can inhibit oxidation during hydrolysis, contribute to an increase in the bio-activity and decrease the bitter taste of the final product. The process can vary in starting material, pre-treatment, type and amount of enzyme, hydrolysis conditions, time, degree of hydrolysis and post-treatment.

A method of sequential isoelectric solubilisation of animal by-product comprising the steps of isoelectric solubilisation of the animal by-product in one of an acid or alkali solution to provide a first solubilised protein fraction, separating the first solubilised protein fraction from unsolubilised animal by-product, isoelectric solubilisation of the unsolubilised animal by-product to provide a second solubilised protein fraction, and separation of the second solubilised protein fraction from unsolubilised animal byproduct. The protein from the first and/or second solubilised protein fractions is recovered by drying or precipitation. In one embodiment, the acid and alkali soluble protein fractions are proportionally combined to neutralise the composite fraction and precipitate protein.

Showb here is a process for preparing a concentrated liquid composition (such as a broth) from poultry or other meat sources without the use of any enzymes. The resultant composition may have high content of solids but are pumpable or pourable and have relatively long shelf life at room temperature. Also shown are methods of extracting proteins from raw poultry or other meat sources at relatively low temperatures. Methods of making a high protein curd is also shown.

The present invention relates to a method for preparing a cartilage product comprising a protein hydrolysate with a degree of hydrolysis comprised between 0.5% and 3.0%, at least one glycosaminoglycan and at least one growth factor. The present invention also relates to the cartilage product obtainable through said method. Said cartilage product is useful in the treatment or prevention of wounds, ulcers, burns, psoriasis, osteoarthritis, synovitis, osteoporosis, osteopenia, diseases of the tendons and ligaments, periodontal diseases, signs of skin aging, the harmful effects of ultraviolet radiation exposure or stretch marks.
