Pre-milling treatments for pigeon pea are generally employed to loosen the seed coat to remove husk without losing any edible portion. The effect of four enzymatic hydrolysis parameters viz., enzyme concentration (20-60 mg/ 100 g dry matter), incubation time (3-15 h), incubation temperature (40-60 0C) and tempering water pH (4.0-6.0) on hulling efficiency, protein content and cooking time were optimized using response surface methodology. Three enzymes, i.e., xylanase, pectinase, and cellulase were used in combination for enzymatic pre-treatment. It predicted a maximum dehulling efficiency ...
