OPTIMIZATION OF LACTIC ACID-ASSISTED EXTRACTION CONDITIONS OF PECTIN FROM PINEAPPLE PEEL BY RESPONSE SURFACE METHOD
摘要
Abstract
To well-utilized pineapple peel pectin, lactic acid-assisted extraction was applied for its extraction from pineapple peel. The single factor experiment and response surface method were used to optimize the effect of processing parameters on extraction yield of pectin such as time, lactic acid concentration, ratio of liquid to material and temperature, the different factors had different effects on the extraction yield of pectin. The results showed that the effect order of four factors on the pectin yield was as follows: temperature, lactic acid concentration, time and ratio of liquid to material. And the optimal extraction conditions of pectin from pineapple peel were: time 96 min, lactic acid concentration 8.25%, ratio of liquid to material 25 mL·g-1, temperature 74℃. The yield of pectin could be up to 8.47% under the optimal extraction condition, the relative error was 0.58% compared with the predictive value, which illustrated the feasible model fitted well with the experimental data. It showed that the conditions were reasonable and feasible.关键词
