【摘要】 研究了以脐橙皮渣为原料,酸水解乙醇沉淀法提取果胶的工艺,通过正交实验,探讨果胶提取的最佳工艺条件,同时以果胶得率×粘度=胶凝单元数(Joily units)作为衡量果胶产量的综合指标。结果表明在温度为85℃,水料比15:1,pH值1.5,时间90min,果胶得率可达18.62％。更多还原

【Abstract】 In this article, a new technology was introduced with hydrochloric acid ethanol deposition of pectin from residue of dry umbilica - like orange peer. The best condition was obtained by orthogonal experiment and the yield was determined by pectin yield and jokily units. The Optimal condition was temperature 85℃, the ration of water to material is 15: 1, pH1. 5, with time 1. 5hour. The pectin yield as 18. 62%.更多还原
