  • Rapid method of assaying collagen in meat and meat products
    Patent number: 4094646
    Abstract: A rapid method for assaying collagen in meat and meat products. A sample of the material being tested is subjected to a controlled, incomplete hydrolysis of the amino acids with an acidified solution of stannous chloride in such a way that all of the tryptophan is completely destroyed but only a portion of the hydroxyproline is hydrolyzed. The percent collagen is correlated with the percent hydroxyproline, colorimetrically determined.
