传统皂素生产工艺在皂素生产过程中,不仅造成了优质淀粉资源的巨大浪费,而且还造成环境污染及其所带来的高昂的污染治理费用。采用水洗淀粉法,即从皂素生产的源头把淀粉从黄姜中分离出来。这种工艺不但回收了淀粉,提高了皂素的收率,淀粉回收率平均约为46.3%,皂素收率提高了1.1%,而且还降低了皂素废水的处理难度,末端废水COD从原来的33615mg/L降为12285mg/L。该工艺简单、投资费用少,在实际生产中有较好的应用前景。
Traditional saponin production process in saponin production process, not only caused a huge waste of high-quality starch resources, but also caused by environmental pollution and its high pollution control costs. The use of washing starch method, that is, from the source of saponin starch from the separation of turmeric. This process not only recovered starch, increased the yield of saponin, the average recovery rate of about 46.3% starch, saponin yield increased by 1.1%, but also reduce the difficulty of the treatment of waste water, end wastewater COD from the original Of 33615mg / L down to 12285mg / L. The process is simple, less investment costs, the actual production has a better application prospects.
