纳滤浓缩2-酮基-L-古龙酸提取液的研究

NF of 2-keto-L-Gulonic acid Extract of Concentrated Study

纳滤膜能在常温下将2-酮基-L-古龙酸发酵液进行超滤提取后的提取液浓缩,替代了原有的蒸发浓缩。既降低了能耗,又防止了料液的高温分解破坏,提高了产品的收率和成品质量,经济效益可观。现纳滤膜成功地运用到VC大生产中。污染后的膜用加酶复合型清洗剂的清洗效果优于单一型酸、碱清洗剂。

Nanofiltration at room temperature can be of 2 - keto-L-gulonic acid fermentation liquid extract after ultrafiltration concentrated extracts of the place of the original evaporation. Not only reduces energy consumption, and prevent the decomposition temperature of the liquid material damage, increased product yield and product quality, substantial economic benefits. Nanofiltration is successfully applied to large-scale production of vitamin C in. Pollution and increase the use of composite membrane-cleaning detergent better than single-acid, alkaline cleaning agent.
