文摘

Gelatin was extracted from the Yak (bos grunniens) skin. The different molecular weight distribution (MWD) Yak skin gelatin was extracted with pepsin by controlling the enzymolysis time. The broad MWD Yak skin gelatin has higher imino acids contents and lower foamability and emulsibility compared with the narrow MWD gelatin. The Yak skin gelatin has good thermotolerance.
