Optimization of acid hydrolysis conditions of delimed tannery fleshings by response surface method
An ecofriendly method, involving mild organic acids to hydrolyse delimed tannery fleshings (TF), has been developed. Combination of formic acid and propionic acid (1:1) was employed to obtain hydrolysates with higher degree of hydrolysis (DH). Better antioxidant properties were obtained by response surface method (RSM) using a factorial design. Effect of pretreatment involving steam cooking (80
