Abstract
The present invention relates to a process for dehydrating naturally occurring organic materials which contain a biologically active component, and in particular proteins, which does not change the original structure of the active component, by drying such material in particulate form in the presence of an antimicrobial agent and preferably an ionizable salt at temperatures at or below which denaturization occurs until the water content of the material is reduced to less than 15%.
Claims10
A method for the dehydration of Type II collagen containing cartilage in its natural form, which comprises,
- (a) combining said cartilage with an antimicrobial agent and at least 15% by weight of the cartilage of an ionizing salt,
- (b) heating the resulting mixture in particulate form at a temperature below which denaturizattion of the Type II collagen occurs until the water content is reduced to below 15% by weight of the cartilage, and
- (c) recovering a product containing the collagen II-containing protein of the cartilage in its original form and having a salt content of at leant 45% by weight of the cartilage.
The method of dehydrating chicken cartilage containing Type II collagen in its natural form which comprises
- (a) comminuting said cartilage,
- (b) soaking the resulting product in an aqueous solution of an antimicrobial agent, and blending such with potassium or sodium chloride in a concentration of at least 15% by weight of the comminuted product,
- (c) dehydrating the resulting mixture in particulate form at temperatures below 110° F. until the water content of the mixture is reduced to below 10%, and recovering a product containing the Type II collagen of the chicken cartilage in its natural form and having a salt content of 45 to 60% by weight of the cartilage.
