The present invention relates to a method for producing collagen peptides from bones, comprising the following steps: a) providing bones of vertebrates; b) mechanically crushing the bones to a particle size of less than 1 000 μm, preferably less than 500 pm, more preferably less than 300 μm, at a temperature of less than 70° C. during the crushing; c) heating the crushed bones in an aqueous suspension to a temperature of above 100° C., preferably above 120° C., more preferably above 130° C., for a period of from 1 to 30 min, preferably 2 to 10 min, more preferably 4 to 8 min; d) adding one or more proteases to the suspension in order to obtain an aqueous solution of collagen peptides; and e) separating off the aqueous solution of collagen peptides from the crushed bones, wherein the method does not comprise maceration of the bones with an acid or liming of the bones with a base, and wherein the bones provided in step a) have not undergone maceration or liming. The invention further relates to collagen peptides produced by this method.

This disclosure provides a high collagen composition prepared from a poultry broth and methods of making the same by filtration.

A cell hydrolysate composition, the composition comprising substantially all protein polypeptides and/or polypeptide fragments derived substantially from all the proteins in a cell from an in vitro cell culture.

A cell hydrolysate composition, the composition comprising substantially all protein polypeptides and/or polypeptide fragments derived substantially from all the proteins in a cell from an in vitro cell culture.

The present invention relates to a protein bar that is formed from a moldable mixture containing proteins and/or protein hydrolysates. The moldable mixture contains a collagen hydrolysate having an average molecular weight of up to 1,700 Da as a protein hydrolysate.

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 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.

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.
