Title: Optimization of extraction process of grapefruit peel pectin based on orthogonal experimental design
Abstract: Based on orthogonal test design of 4 factors and 3 levels,the optimum process condition of grapefruit peel pectin are as follows: the dry material mixed with water at a ratio of 15∶1,95 ℃ and pH 1.5 for 60 min.Single factor optimization experiments show that 1) microwave assisted extraction can shorten extracting time,preferably in 6 minutes,2) lactic acid is more conducive to the dissolution of pectin,and the extraction rate can reach 17%,3) in the pectin preparation process,the use of dry peel is recommended,but not using activity carbon.
