Optimization of Dietary Fiber Extraction from Pineapple Pomace by Response Surface Methodology
2018
Taking pineapple peel as raw material, the dietary fiber in pineapple pomace was extracted by enzymatic method combined with the chemical chemicalchemicalchemical chemical method. The effects of enzyme dosage, enzymolysis timetimetimetime, alkaline pH and alkali solution time on the yield of pineapple pomace dietary fiber were studied. And optimize the extraction process. The results showed that the optimal extraction process parameters of pineapple pomace were as follows: enzyme dosage 480u/g, enzyme hydrolysis time 43 minute, alkaline hydrolysis pH=12, alkaline hydrolysis time 60 minute, pineapple pomace dietary fiber under these conditions, the yield can reach 78.86%. The mathematical model is feasible for optimizing the extraction process of pineapple pomace dietary fiber.
