 二丁基羟基甲苯

中文名称:二丁基羟基甲苯

中文别名:2,6-二叔丁基对甲酚;3,5-二叔丁基-4-羟基甲苯;BHT

英文名称:butylated hydroxytoluene(BHT)

分子式: C15H24O

分子量:220.36

CAS89797-68-2

理化性质:无嗅、无味,无毒的白色晶体。熔点71,沸点265,不溶于水和稀碱,溶于苯、甲苯、乙醇、汽油及食物油中。其溶解度为:乙醇25%(20),豆油30%(25),棉籽油20%(25),猪油40%(40)。

作用机理:二丁基羟基甲苯(BHT)作为抗氧剂,它能够与自动氧化中的链增长自由基反应,消灭自由基,从而是链式反应中断。二丁基羟基甲苯(BHT)在抗氧化过程中既可以作为氢的给予体也可以作为自由基俘获剂。由于2,6位上有2个强力推电子基团,因此,二丁基羟基甲苯(BHT)具有很强的抗氧化效果

用途:GB2760—2011规定为暂时允许使用的食品用香料。作为抗氧剂,能抑制或延缓塑料或橡胶的氧化降解而延长使用寿命。防止润滑油、燃料油的酸值或粘度的上升。作为食品添加剂能延迟食物的酸败。本品又是合成橡胶(丁苯、丁腈、聚氨酯、顺丁等)、聚乙烯、聚氯乙烯的稳定剂。BHT也是国内外广泛使用的油溶性抗氧化剂。因其抗氧化能力较强,耐热及稳定性好,无特异臭,遇金属无呈色反应,且价格低廉,所以在我国为主要的抗氧化剂。

使用限量:FEMA   (g/kg): 1、脂肪,油和乳化脂肪制品0.2;基本不含水的脂肪和油0.2;干制蔬菜(仅限脱脂马铃薯粉)0.2;熟制坚果与籽类(仅限油炸坚果与籽类)0.2;坚果与籽类罐头0.2;胶基糖果0.4;油炸面制品0.2;即食谷物,包括碾压燕麦(片)0.2;方便米面制品0.2;饼干0.2;腌腊肉制品类(如咸肉、腊肉、板鸭、中式火腿、腊肠)0.2;风干、烘干、压干等水产品0.2;膨化食品0.2以油脂中的含量计。
