一些人在选购蜂蜜时,以为蜂蜜中出现白色结晶体是掺糖的假蜜。其实,有结晶体的蜂蜜才是纯正的蜂蜜。蜂蜜为什么会形成结晶呢?原来,蜂蜜中含有42.2％的葡萄糖、34.2％的果糖、0.37％的糊精和20％左右的水分等。蜂蜜中的葡萄糖在较低的温度下,极易形成结晶。果糖和糊精几乎不结晶。因此,蜂蜜的结晶体,实际上就是葡萄糖的结晶,而不是白糖的结晶。实验证明,掺入白糖后的蜂蜜 Some people in the purchase of honey, honey that appears in the white crystals are sugar-doped fake honey. In fact, there is crystal honey is pure honey. Why does honey form crystals? Originally, honey contains 42.2% glucose, 34.2% fructose, 0.37% dextrin and about 20% moisture. The glucose in honey at low temperatures, extremely easy to form crystals. Fructose and dextrin hardly crystallize. Therefore, the crystal of honey, in fact, is the crystallization of glucose, rather than the crystallization of sugar. Experiments show that after the honey mixed with sugar
