Acid and Salt-Soluble Collagen in Bovine Muscle.

Abstract

Summary Salt- and acid-soluble collagens in bovine muscle tissue were investigated, utilizing modified procedures employed for purified collagen sources. The quantity of salt-soluble collagen in shank muscles decreased during post mortem aging, while acid-soluble collagen increased. Age differences were evident for acid- and salt-soluble collagen. The quantity of acid- and salt-soluble collagen in the fore shank muscles of cattle did not differ significantly between tender and less tender groups.
