羟基香茅醛

羟基香茅醛用途

【用途一】
用于配制水仙、铃兰、茉莉及风信子香型香精
【用途二】
GB 2760—96规定为允许使用的食用香料。主要用于配制柑橘、西瓜、樱桃等瓜果型香精，亦作定香剂和调香辅助剂用。
【用途三】
羟基香茅醛是我国《食品添加剂使用卫生标准》规定允许使用的食品香料，主要用于配制樱桃、柑橘、西瓜等瓜果型食用香精。在口香糖中使用量为16mg/kg；冷饮中13mg/kg；烘烤食品畸10mg/kg；糖果中9.4mg/kg；软饮料中3.5mg/kg；布丁类中0.3mg/kg。
【用途四】
是一种多用途的香料，既可用于各种花香型，也用于许多非花型。用于铃兰、菩提花、百合花及与此同类香气的兔耳草花、紫丁香等型，能使香气细腻。在香水香精中用之，可赋花香头香。也可用香皂香精及橙花、白柠檬等香精。质量纯正的可适量用于食用香精，能赋花香，增厚增浓，使香味圆和。
【用途五】
该品稀释时具有类似菩提、铃兰和新鲜的青草香气，广泛用于铃兰、兰花、茉莉、紫丁香等香精中，在香水、香粉等化妆品香精中用量高达20%，是最有价值的香料之一。该品是我国GB2760-86规定允许使用的食用香料，主要用于配制柑桔、西瓜、樱桃等瓜果型香精。由于该品易氧化，可添加抗氧剂3,6-二叔丁基-4-甲基苯酚作稳定。羟基香茅醛在碱性中不稳定，故在肥皂香精中使用其缩醛，例如二甲缩醛等，有时将羟基香茅醛与苄醇、苯乙醇以及香茅醇以半缩醛形式存放和使用。羟基香茅醛还用来制取其他香料，如1-氨基-7-羟基-3,7-二甲基辛烷和邻羟基香茅叉氨基苯甲酸甲酯。曾用含0.5%该品饲料喂大鼠两年，未发现任何异现象。

羟基香茅醛制备

1.将香茅醛与亚硫酸氢钠在冷却下反应，然后用14%～15%的盐酸溶液，在35℃下进行水合反应，并加入碳酸钠中和剩余的盐酸至物料中含酸量为0.5%～1%为止。先用少量甲苯萃取去除有机杂质，然后在水合物中添加甲苯和干燥的碳酸钠，以分解亚硫酸氢盐，生成的羟基香茅醛为甲苯所萃取。甲苯萃取液先回收甲苯，再减压蒸馏得产品羟基香茅醛。

2.由香茅醛与水加成，经精制而得。
