Abstract

Effects of enzymolysis treatment on the quality of freeze-dried meal replacement porridge were investigated. The optimal technological parameters (59℃, α -amylase 2000 U/g, saccharase 4200 U/g, cellulase 3800 U/g, digestion time 39 min) were gained by single test, Plackett-Burman test and Box-Behnken response surface. After enzymatic hydrolysis, the instant solubility of the product was greatly improved, and the total flavone and content sensory quality of the product was increased
