补充资料:D-阿拉伯型已酮糖
分子式:C6H12O6
分子量:180.160
CAS号:57-48-7

性质:果糖为白色棱柱状结晶。在天然产物中常常以呋喃型果糖相结合,在水溶液中,呋喃型果糖和吡喃型果糖同时存在,在20℃水溶液中大约有20%呋喃型果糖。果糖熔点102-104℃(分解),相对密度1.6(20/4℃)。易溶于水,溶于乙醇,甲醇和吡啶,微溶于丙酮。极易潮解。果糖是所有糖中最甜的一种,甜度约为蔗糖的1.5倍,在低温下更甜。

制备方法:果糖以游离的形态大量存在于水果的浆汁和糖蜜中,由菊芋水解可得到果糖。将含有果糖的多糖体菊粉(Inulin,在秋季,土木香,蒲公英,大丽花等根中菊粉含量可达40%之多)进行水解,生成果糖,经分离而得成品,这是生产果糖的方法之一。蔗糖是工业生产果糖最丰富的原料,用稀酸或转化酶水解蔗糖,从混杂有D-葡萄糖的溶液中析离果糖,果糖不易结晶,但它与氢氧化钙形成不溶性的复合物,分离后,通入二氧化碳,即可得到果糖结晶。利用蔗糖发酵制葡聚糖的发酵糖液,经毡袋过滤器过滤,送入乙醇蒸馏塔回收乙醇,蒸馏后的废糖液加0.25%(重量/体积)活性炭搅拌,待液温降至40℃以下进行离子交换,分离得到果糖。目前工业上大规模生产采用淀粉水解制备葡萄糖,经固定化葡萄糖异构酶转化为转化糖,其中含有42%果糖和58%葡萄糖,商业上称果葡萄糖浆或高果糖浆。它的甜度与蔗糖相当,但具有天然蜂蜜香味和生产成本低等特点,已广泛用于饮料和糖果糕点等食品工业。

用途:果糖有直接供给热能,补充体液及营养全身的功效,比葡萄糖容易吸收利用,用作供给能量补充体液比葡萄糖更佳。除作为药物外,也用于高级糖果,婴儿饮料中。果糖也用作生化试剂。
