β-胡萝卜素分子式:C40H56分子量:536.88CAS号:7235-40-7性质:纯净的产品为深红色或暗红色、有光泽的斜方六面体或结晶状粉末,对氧、热及光不稳定,是类胡萝卜素之一。它是自然界中存在最普遍、最稳定的天然色素,许多天然食物如螺旋藻、绿色蔬菜、甘薯、胡萝卜、菠菜、木瓜、芒果等,皆存有β-胡萝卜素。熔点183℃。溶于二硫化碳、苯、氯仿。0℃时在100ml己烷中可溶该品109mg,不溶于水、丙二醇、甘油,几乎不溶于甲醇和乙醇,对氧、热及光不稳定。制备方法:1.从天然物萃取 天然β-胡萝卜素通常有植物萃取、盐藻萃取和发酵法三种方法生产。中国主要采用盐藻萃取方法和发酵法,植物提取方法国内已经淘汰。2.合成法 合成法的中间体3,8-二甲基-3,5,7-十三烯-1,9-二炔苯基锂及4-(2,6,6-三甲基-1-环己烯-1-基)-2-甲基-2-丁烯-1-醛的制备方法载于美国专利2917539。工业品一般制成β-胡萝卜素的食用油脂溶液或悬浮液、乳化液以及可分散于水的粉末。为提高其稳定性,可添加抗氧剂、乳化剂、分散剂,并可含有不同的比例的反式/顺式异构体。用途:营养增补剂和色素。按我国卫生部颁布的“食品营养强化剂使用卫生标准(1993)”规定,可用于奶油及膨化食品,最大使用量0.2g/kg。该品0.6μg的生理作用相当于1国际单位(I·U·)的维生素A。现广泛用作黄色色素代替油溶性焦油系色素,如用于原为就含有胡萝卜素的奶油、干酪、蛋黄酱等,并广泛应用于其他食用油脂、人造奶油、起酥油、糕点、面包等。用于油性食品时,常溶解于棉籽油之类的食用油或悬浊制剂(含量30%)。经稀释后即便于使用,也可防止β-胡萝卜素氧化。一般添加α-生育酚、硬脂酰抗坏血酸酯、BHA等的抗氧化剂。用作色素添加量较少,如用于人造奶油为1.37mg/kg。在果汁中与维生素C合用,可提高稳定性。
