  • 用途四:GB 2760—1996规定为
  • 使用限量:FEMA(mg/kg):软饮料7.4;冷饮8.0;糖果11;焙烤食品12;布丁类1.9。 适度为限(FDA§172.515,2000)。
  • FEMA:2099
  • 不溶于水,溶于1体积50%醇,溶于醚。
  • 方法二:由大茴香醛还原制得。将大茴香和甲醛、氢氧化钠在乙醇中发生康尼查罗(Cannizzaro)反应,生成对甲氧基苯甲醇。蒸馏回收乙醇后,反应所得油层用苯萃取,加乙酸酸化,再用碳酸氢钠中和至弱碱性,水洗至中性后,蒸馏回收苯,剩余物进行减压蒸馏,得对甲氧基苯甲醇。
  • 上游原料:对甲氧基苯甲醛 --> 氯化亚铁 --> 铂金
  • 用途三:主要用于带清香的花香型香精中,如山楂花、茉莉、金合欢、含羞花、刺槐、紫丁香、铃兰、紫罗兰、玉兰、葵花、水仙等

  • 八角茴香油:八角茴香油又称八角油,在20摄氏度以上时为无色透明或淡黄色液体,温度下降时会有片状结晶析出,有茴香脑的香气和甜味。微溶于水,易溶于乙醇、乙醚和氯仿中。八角系木兰科,八角属。其果实是聚合果,呈八角形,故俗称为八角茴香,也称大料等。八角茴香油是一种成分复杂的芳香油,是挥发油,略具粘性。色泽以灰白色为好,黄色则稍次,味甘美而刺舌,具有强烈的八角香气。在10-15℃的温度下,搅拌之则凝结。其主要成分是反式大茴香脑,含量高达80%以上。还含有α-蒎烯、柠檬烯、芳樟醇、黄樟素、大茴香醛、茴香酮、4-萜品醇、草蒿脑、茴香醛等成分。八角油是一种技术性较强,没有化学仪器不容易鉴别的芳香油。目前产区还是通过收购员用肉眼看、鼻子闻来鉴定八角油的品质。八角油在香料工业中主要用于提取大茴香脑,并再合成大茴香醛、大茴香醇(对甲氧基苯甲醇、4-甲氧基苄醇)。些单体香料均广泛用于牙膏、食品、香皂和化妆品香精。其果实是我国人民常用的食品调味香料。同时八角油在制药工业中是合成阴性激素已烷雌酚的主要原料。由于八角油比水轻,悬浮于水面上,油水分离后的水含有八角油返回蒸馏锅进行复馏以提高出油率。
  • 含量分析:按总醇量测定法(OT-5)进行。其中皂化用的乙酰化醇量取1.5g。计算中的当量因子(e)取69.09。或按GT-10-4中气相色谱法非极性柱方法测定。
