【摘要】 以苹果渣为原料探讨了用沉淀法提取果胶的工艺条件.分别采用Al2(SO4)3和乙醇作为果胶沉淀剂,通过对沉淀时的沉淀剂用量、pH值、反应温度及反应时间等影响因素的研究,得到了提取果胶的最佳工艺条件,为实际生产提供了依据.更多还原

【Abstract】 The precipitation conditions during extracting pectin from apple residue are discussed. And the influence of some factors is studied, such as expenditure of precipitant, pH, reactive temperature and time by using the Al2(SO4)3 and alcohol as the different precipitant, and the optimal precipitation condition is obtained of extracting pectin, which lays a foundation for practical process.更多还原
