从花生壳中提取菲丁的工艺探讨

Study on the Technology of Extracting Phytin from Peanut Shell

摘要: 用“逆流两浸一洗循环法”提取花生壳中菲丁，提取率可达３．１％～３．２％。洗去花生壳中的灰沙，不用铁质设备粉碎，浸酸时加入０．３％～０．８％的ＮａＣｌ，用活性炭脱色，可消除有色有机物及金属离子对产品质量的影响。

Abstract: The phytin in peanut shell was extracted, by using the method of twice-soaking,once-washing and adverse current circulating.The percentage extraction of 3.1%～3 2% was achieved. Adding sodium chloride of 0.3%～0 8% in the acid-soaking process and decoloring with active charcoal can improve the quality of phytin.
