其他信息

  • 应用与用途:(1) 曲酸在食品生产中有非常广泛的应用。以往曲酸由于有抗氧化性曾用于油脂防止酸败,近年来的文献报道,曲酸有杀菌抗虫作用,作为食品的防腐剂、保鲜剂、护色剂使用有明显的效果,可替代化学防腐剂广泛用于肉食品加工护色、果蔬保鲜、生食品的杀菌防腐中,还可用作切花保持剂延长鲜花保存及货架期等。食品中添加曲酸,既不会影响其本身的口味、香味及质感,又能阻碍亚硝酸盐转化成对人体有致癌危害的亚硝胺,这种阻碍或抑制作用,对腌腊肉制品类产品的换代升级有着非常重要的意义。农业生产方面,曲酸既可用作生物农药,用作杀虫剂,又可用作生物肥料,不论喷施还是根施,对粮食和蔬菜的增产增收效果显著。 (2) 作为食品增香剂麦芽酚和乙基麦芽酚
  • 有机酸:曲酸又称曲菌酸、鞠酸,是由葡萄糖经曲霉念珠菌在30~32℃下好氧发酵产生的具有抗菌作用的有机酸,分子结构为带取代基的γ-吡喃酮,在自然界存在的γ-吡喃酮化合物中,著名的化合物只有曲酸和麦芽酚。1907年Saito由米曲中分离出曲酸结晶。1912年由Yabuta命名并于1924年确定其结构。1953年Arnstela(表面发酵)和1971年北田牧夫(深层发酵)运用同位素追踪技术证明曲酸是葡萄糖未经碳架断裂直接氧化、脱水形成的。 曲酸存在于曲中,它是人们食用的东西,使用安全。近年来,大量的专利文献报道曲酸在化妆品中的应用。酪氨酸酶是生成黑色素的关键酶。曲酸能与酪氨酸酶的铜螯合而使之失去活性,这是其美白作用的基础。临床和应用试验结果表明,曲酸对人体皮肤的黑色素生成有较强的抑制作用,而且安全,无毒,不会引起白斑后遗症。曲酸与其它制剂(如SOD,胎盘提取物、氨基酸、防晒剂和各类植物提取物等)复配使用效果更好。曲酸主要用于皮肤增白制品、抗衰老制品、防晒制品、增白洗面奶和美容化妆品。 曲酸具有一定的抗菌活性。革兰氏阴性细菌对曲酸钠的敏感程度大于革兰氏阳性细菌,而大多数其他抗菌物质则相反。曲酸的抑菌作用远低于其他抗菌物质,其抗菌活性是抑菌性而非杀菌性。曲酸对酵母、病毒和噬菌体无效。 以上信息由Chemicalbook的彤彤编辑整理。

  • 曲酸的提取及精制:曲酸与2价金属离子可形成难溶性的金属螯合物,这一性质可在提取时利用。其次,曲酸虽然溶于水但溶解度不大,温度对其溶解度影响很大,有利于浓缩降温结晶。 曲酸可作为铁试剂。即使使用不锈钢发酵罐,其发酵液也呈红褐色,这一性质影响到提取、精制过程。 从发酵液中提取曲酸曾用过铜盐沉淀法、醋酸乙酯萃取法、乙醚连续萃取法、浓缩结晶或冷冻结晶法等。20世纪70年代,北京日化一厂使用锌盐法。
  • 微生物发酵法制曲酸:微生物发酵法制曲酸是指用微生物发酵法大量生产曲酸的工艺和技术。曲酸是由米曲霉等微生物产生的一种酸性代谢产物,能溶于水、乙醇或醋酸酯等。能产生曲酸的微生物多数为真菌,如米曲霉(Aspergillus oryzae)、米黄曲霉 (A.flavo-oryzae)、黄曲霉(A.flavus)、亮白曲霉(A.candidus)、棒曲霉(A. clavatus)、巨大曲霉(A.giganteus)、烟曲霉(A.fumigatus)、溜曲霉(A.tamarii)、温特曲霉(A.wentii)和灰绿曲霉(A.glaucus)等。某些细菌如玫瑰葡糖杆菌 (Gluconobacter roseus)、蜡状葡糖杆菌(G.cerinus)和若干假单胞菌(Pseudomonas spp)也可利用糖类生成曲酸。基本发酵工艺为:甘薯粉经α-淀粉酶水解→灭菌→在发酵罐中冷却→接种米曲霉种子(来自种子罐)→32℃左右通气发酵(约5天)→发酵液抽滤→制成曲酸的锌盐→减压浓缩→结晶→酸化→曲酸。曲酸是用于制造食品和日用品中的增香剂麦芽酚和乙基麦芽酚的原料,也是生产杀虫剂、杀菌剂和胶片脱尘剂的原料,若与某些脂肪族羧酸发生酰化,就可获得曲酸酯,它是制造增白化妆品的原料。 参考资料:周德庆,徐士菊 编著.微生物学词典.天津:天津科学技术出版社.2005.
  • 美白化妆品和美白食品中添加曲酸:曲酸为酪氨酸酶抑制剂,能抢先与酪氨酸酶中的铜离子熬合,使铜离子失去作用,进而抑制多巴色素的合成。 曲酸能抑制5,6-二羟基吲哚(DHI)聚合,抑制DHICA氧化酶的活性。 添加曲酸的化妆品有护肤、润肤、美白、光亮、防晒、祛斑的功能。剂型有膏霜、洗剂、乳液、软膜粉、泥胶、粉饼等。 国内最早 (1987年) 研制并获得卫生部批准文号 (1991年) 的是南京石山头制药厂的142-曲酸祛斑霜,其曲酸含量有1.5%、2.0%两种规格。主要用于治疗各
