| Abstract: | In this article is reported the extraction of high-methoxyl pectin from dried pomelo peel with dilute hydrochloric acid followed by preci- pitation with alcohol.Experiments were arranged in accordance with the orthogonal design method and variance analysis was made to study the effects of the extraction pH value,extraction temperature,extraction duration, water peel ratio,washwater temperature,wash duration and final alcohol concentration,and precipitation duration on gel power,purity and productivity,so as to determine the optimum technological conditions for the production of HM-pectin.Under these conditions the pectin productivity was 12.1%;gel power 181°;and purity 73.2%. |
