The characteristics of collagen hydrolysis products
The characteristics of collagen hydrolysis products were investigated. Sodium hydroxide, formic, acetic, oxalic and amber acids were hydrolysing agents. The main indices under the control were density, ductility, рН, surface tension, molecular weight of collagen hydrolysis products, chemical and biological use of oxygen. Data of changing characteristics of collagen hydrolysis products from the time of keeping are obtained.
