ANALYTICAL CHALLENGES
• Collagen is a complex molecule to purify and analyze.
• Testing is complicated once the collagen is hydrolyzed and
fragmented into peptides, which can widely vary in size, length and
molecular weight distribution depending on a host of factors
including production method, process time, hydrolysis method, and
raw material source.
• Need cost effective, quick turnaround analysis time and simple test
method that can be run in an in-house laboratory.
COMMON ADULTERANTS
•
Type I & III Collagen / Gelatin products are sometimes
adulterated with lower cost proteins.
•
Type II Collagen is adulterated with type I & III
collagen/gelatin and other lower cost proteins.
