A method for producing a collagenous material in particle form, includes: extracting a collagen- and fat-containing animal raw material using an aqueous extraction solution; optionally separating at least one part of the aqueous phase from the extraction residue; separating the extraction residue into a collagenous solid phase, an aqueous phase, and a fat phase; mixing at least one part of the collagenous solid phase with at least one part of the aqueous phase; at least partly drying the mixed phases; and comminuting the dried phases in order to obtain the collagenous material in particle form.

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 present disclosure relates to pharmaceutical field, providing a hydrolyzed chicken sternal cartilage extract, method for producing the same and use thereof. The hydrolyzed chicken sternal cartilage extract has a type II collagen content of 50% and a chondroitin sulfate content of 20%. In China, a huge amount of livestock and poultry are consumed, and the total consumption almost reaches of the worldwide livestock and poultry consumption. Chicken sternal cartilage is one of the main by-products in broiler chicken processing. In the present disclosure, a hydrolyzed chicken sternal cartilage extract rich in type II collagen and chondroitin sulfate is obtained by using biological enzymatic hydrolysis technique. Experiments results show that the hydrolyzed chicken sternal cartilage extract produced by the present disclosure has a good anti-inflammatory effect and can be used to prepare medications for treating osteoarthritis.
