海藻糖的特性及其应用

Application prospect of trehalose

海藻糖是由两个葡萄糖分子以α,α,1,1-糖苷键构成的非还原性糖,自身性质非常稳定,具有独特的生物学特性、对生物抗脱水的保护作用、抗冷冻保护作用和抗高渗保护作用,同时赋予了防止淀粉老化、防止蛋白质变性、抑制脂类物质酸败、抑制鱼腥味的生成、矫正味道和矫正气味作用、抑制大米的米糠臭、保鲜、稳定物料中的超氧化物歧化酶、防蛀牙和补充能源等功能特性。而自然界中如蔗糖、葡萄糖等其它糖类,均不具备对多种生物活性物质具有神奇的保护作用这一功能;这一独特的功能特性,使得海藻糖除了可以作为蛋白质药物、酶、疫苗和其他生物制品的优良活性保护剂以外,还是保持细胞活性、保湿类化妆品的重要成分,更可作为防止食品劣化、保持食品新鲜风味、提升食品品质的独特食品配料,拓展了海藻糖作为天然食用甜味糖的功能。

Trehalose is a non-reducing sugar formed by two glucose molecules between α,α-1,1-glycosidic bond and is one of the most stable sugars in the world.It can effectively prevent organism damage in freezing,drying and heating.It has special biologic characteristic including dehydration tolerance,freezing tolerance and hypertonic tolerance.It can also prevent starch retrogradation,protein denaturation,lipids rancidity,fishy smell inhibition,keeping rice fresh and stabling SOD in the raw material.It is also an en...
