a, b Digestibility of porcine hide depending on treatment time, kind of enzyme without (left) and with synthetic crosslinking (right); filled triangle: collagenase A; open circle: proteinase K; filled square: pronase E; open triangle: trypsin; filled diamond: thermolysin; open square: chymotrypsin. All experiments with the same enzyme activity (unpublished data by Michaela Schroepfer, FILK). c, d Digestibility of heat-treated, denatured porcine hide depending on treatment time, kind of enzyme without (left) and with synthetic crosslinking (right); filled triangle: collagenase A; open circle: proteinase K; filled square: pronase E; open triangle: trypsin; filled diamond: thermolysin; open square: chymotrypsin.
