Values are expressed as mean ± SD (n = 3)

Different superscript letters in the same row indicate significant differences (p < 0.05), ANOVA followed by Tukey’s

P1-1U and P1-2U represent gelatin hydrolysate produced during gelatin extraction with enzyme concentrations of 1 and 2 units/g dry swollen skin, respectively. P2-1U and P2-2U represent gelatin hydrolysate produced after gelatin extraction with enzyme concentrations of 1 and 2 units/g dry swollen skin, respectively
