Description
技术领域
本发明属于化工技术领域,涉及一种植酸提取用吸附树脂的制备方法及其使用方法。
背景技术
植酸又名肌醇六磷酸酷,主要以钙镁的复盐(即菲汀)形式广泛存在于天然植物种子、胚芽、鼓皮、米糠中,是一种由谷物副产品等通过精细加工提炼而成的天然产品。植酸是一种重要的有机磷添加剂,具有独特的化学性质和生理药理功能,可广泛应用于食品、水果保鲜、医药、日用化工、金属加工、纺织工业、高分子工业、燃料工业和环保等行业。随着人们绿色消费观念的增强,人们对食品防腐保鲜剂的要求越来越高。国家计委、国家经贸委和农业部联合发布的全国食品工业十五发展规划中指出,我国食品添加剂发展的方向是天然、营养、多功能且安全可靠。天然提取的植酸毒性极低,比食盐更安全,因此其作为新型食品防腐剂、抗氧化剂和保鲜剂而受到越来越多的关注。
植酸的生产方法有化学合成法、微生物发酵法、溶剂萃取法三种。
1)化学合成法:该法是以肌醇和五氧化二磷为原料,经过化学反应制得植酸。该法虽然可行,但是无工业意义,操作起来不仅麻烦,成本也很大,因此一般工业生产不会用到此方法。
2)微生物发酵法:该法主要是对土壤中的微生物进行分离和筛选,选出能生产植酸的菌株—粗糙链孢霉肌醇缺陷型突变菌株,然后通过微生物发酵产生植酸。同时还采用生物的方法,通过基因克隆,培育出植酸生产工程菌,从而实现植酸的大规模生产。生物发酵法具有广阔的发展前景,是未来制取植酸的发展方向。
3)溶剂萃取法:溶剂萃取法是工业生产中普遍采用的方法。生产过程为:用酸溶液浸泡原料,使原料中植酸钙溶解,溶解完全后再加碱进行中和,即可得到植酸钙镁盐的沉淀,过滤沉淀,酸洗沉淀,将酸洗液经阳离子交换树脂洗脱,洗脱液流经阴离子交换树脂进行二次洗脱,得到的洗脱液经脱色和旋转蒸发仪浓缩即可得到植酸制品。酸浸以后,一般采用抽滤或离心过滤,以除去糠渣,一般情况下滤渣需要重新酸浸以提高萃取率,得到的是可溶性的植酸酸式盐和可溶性盐类,同时还有色素、糖类、蛋白质、无机磷等杂质,需进一步分离。滤液加入1/10000的聚丙烯酸酰胺,充分混和,静置,过滤,可除去大部分的蛋白质、色素、糖类等。此时滤液中主要成分为:可溶性的植酸酸式盐和可溶性盐类,无机磷和少量未除净蛋白质、色素、糖类等。
植酸主要以植酸钙镁复盐(菲汀)的形式存在于植物内。在酸性条件下植酸对金属离子的络合作用大大降低,当有强酸存在的条件下(溶液的pH<3)时金属离子呈解离状态,菲汀溶解。如果此时向溶液中加入碱,溶液酸性减弱,碱性增强,此时金属离子的络合作用随之加强,当碱性达到一定程度的时候(pH>4),络合作用最强,于是形成的植酸钙镁复盐又沉淀下来。该法的优点是工艺流程简单,操作容易,成本较小,缺点是得到的植酸提取率相对较小。
