| Abstract: | Objective To inspect the main factors of acid extraction of pineapple peel pectin, and determine the best process conditions of acid extraction of pectin. Methods Through orthogonal test, inspected the effects of solid-liquid ratio, extraction temperature, extraction time and extraction acidity on the extraction of pineapple peel pectin to get best extraction process. Results The optimum conditions of cellulase assisted acid extraction of pineapple peel pectin ： solid-liquid ratio of 1 ： 20, extraction temperature of 80℃, extraction time of 60 minutes, extraction pH was 2.0. Conclusion Cellulase assisted acid extraction method has advantages of high extraction ratio and speed rate, less solvent, safety, energy-saving, simple equipment. The study laid the foundation to optimize the extraction process of the pineapple peel pectin. |
