β －环状糊精生产厂家 β －环状糊精价格 食品级β －环状糊精 β －环状糊精价格批发
【中文别名】
贝塔环糊精、环七糖、环麦芽七糖
【性状】
白色结晶，在水中比较容易结晶。
【简介】
在水中的溶解度比较低，在室温下为1.85%，随着温度增加溶解度增加。不具有吸湿性，但是容易形成稳定的水合物。在相对湿度50-70%之间的水合程度相当于每分子β-CD吸收10-11个水分子(含水量在13.7-14.8%)，吸湿等温曲线为两个相。不溶于一般有机溶剂，但在吡啶、二甲基甲酰胺、二甲基亚砜和乙二醇中能够微溶。

【产品用途】
1. 在食品加工和保存过程中β-CD可以防止各种香料、油料、香辛料及其它易挥发物质的挥发，长期保持食品香味不变。β-CD可以保持易氧化、遇光分解、遇热易变质的色素、氨基酸和维生素等营养成份的稳定。
2. β-CD可以除去鱼、肉腥味及食品中补加维生素B等营养成份后的不愉快味道及其它食品中的异味，增加食品的适口性，也可以改善糖精和甜蜜素等甜味剂的口感。
3. β-CD对于含油量高的饮料，如：冰淇淋、咖啡饮料及其它乳化食品等均可使其形成长期移稳定的乳状液。若与食品乳化剂配合使用，乳化效果更佳。
4.β-CD可以使食品防腐剂、保鲜剂缓慢释放，提高防腐效果，延长食品保质期。
二、β －环状糊精在医药中的应用:
1．β-CD可防止硝基甘油、冰片、萘等药物的挥发；防止氯霉素、维生素、氨基酸及其它激素类药物氧化、光变质和热破坏，提高药物的稳定性。
2．β-CD可提高不溶性药品的水溶性；β-CD可使异羟洋地黄毒苷溶解度提高200倍，服后便于体内吸收，提高生物利用率。
3．β-CD可降低冬眠灵，苯二氨杂草等，除去药物中的苦涩味。
4．β-CD可起免疫诱导剂的作用，抑制毒的增殖。新型植物生长调节剂和农药增
5.β-CD可以调节植物激素，提高生物效应，能使果实早熟，提高糖份，增加色素，产量成倍增长。
6. β-CD可提高
