Processes for separating and isolating proteins and fats from biomass matter utilizes a pH adjustment of a slurry. The biomass feedstock is derived from commingled animal and/or plant-based streams with highly variable concentrations of fat, proteins and impurities present in the biomass. A wide range of pH adjustment spanning highly acid to highly basic has been shown to be effective at separating the commingled streams into their constituent products. The processes do not rely on the proteins being solubilized into the solution, but rather solubilizing the fat portion, physically separating the constituents and precipitating the fat in a downstream process, resulting in two value streams: a highly digestible protein component and a fat component. The protein component has nutritional value as companion pet, animal and aquaculture feed ingredient and the fat component has value as standalone or blended solid or liquid biofuels, greases or specialty chemicals.

A method for obtaining products for the food industry and/or feed industry from insects at the larval stage involves: a) comminuting the insects to form an insect pulp; b) shifting the pH-value of the insect pulp to an acid range by adding an acid and malaxing the insect pulp for a period of at least 45 minutes; and c) fractioning the insect pulp using centrifugal treatment into at least two fractions i) a solid fraction, ii) a fatty phase; and a fat-reduced solid phase.

Disclosed herein are methods for efficiently isolating collagen form a collagen source. The methods are inexpensive and do not require the use of proteolytic enzymes, decolorizing agents, antibacterial and antifungal agents, and the like. Further, the collagen produced by the methods described herein is substantially free of odor and discoloration. Still further, the collagen produced by the methods described herein is suitable to be used in cosmetics, food products, and pharmaceuticals or nutritional supplements.

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.

The invention relates to a protein hydrolysate and a process for making such protein hydrolysate. In particular the invention relates to a collagen hydrolysate and a process for making such collagen hydrolysate. Further the invention relates to a food, pet food, cosmetic, pharmaceutical or technical application comprising the protein hydrolysate of the present invention and further food, pet food, cosmetic, pharmaceutical or technical constituents.

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.

The present invention relates to a method of enriching or screening for one or more target molecules from a primary source, which method comprises to provide at least one peptidic ligand comprising at least one lysine (K) and immobilized to a solid support; contacting the ligand(s) with a primary source comprising at least one target molecule comprising glutamine (Q); allowing the formation of complexes between the ligand and the target molecule; and separating the complexes from the primary source. The target molecule(s) comprises glutamine, and step c is performed in the presence of a catalytic protein comprising transglutaminase (TG). The catalytic protein comprising transglutaminase (TG) may comprise transglutaminase originating from fish, such as Atlantic cod TG (AcTG), e.g. AcTG-1, and the primary source may include waste material from the fish or dairy industry.

Disclosed 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 disclosed 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.

The present disclosure relates to methods for treating at least one source of proteins, treated protein material obtainable by said method of treatment, and food compositions for animals, preferably for pets, including said treated protein material.
