Optimization of Polysaccharide Extraction from Papaya by Orthogonal Experiment Design
摘要
Abstract
[Objective] To optimize the extraction process of papaya polysaccharide by ultrasonic assisted hot water extraction, and improve the yield. [Method]The effects of four factors such as ultrasonic treatment time A (min), extraction time B (min), solid-liquid ratio C (mg/mL) and extraction temperature D (℃),on the yield of polysaccharide were investigated by L27(313) orthogonal experiment, taking into account the possible interactions AB,AC and AD. Finally,the optimal level combination was found.[Result]By considering the interac-tion and designing the four-factor three-level orthogonal test using L27(313),the optimal combination of technological level is A3B2C1D3,that is,ultrasonic treatment time 40 min,extraction time 60 min,solid-liquid ratio 1:30 mg/mL,and the extraction temperature was 80 ℃. The optimal yield of papaya polysaccharide was 15.2% under the optimal combination condition.[Conclusion] The optimal process combination of polysaccharide extraction from papaya was determined,which provided technical guidance for the development and utilization of papaya poly-saccharide.关键词
