Isomaltulose is a disaccharide carbohydrate composed of glucose and fructose linked by an alpha-1,6-glycosidic bond (chemical name: 6-0-α-D-glucopyranosyl-D-fructose). It is naturally present in honey and sugar cane extracts. It tastes similar to sucrose with half the sweetness. Isomaltulose is also known by the trade name Palatinose™, which is manufactured by enzymatic rearrangement (isomerization) from sucrose. The enzyme and its source were discovered in Germany in 1950. After evaluation of its basic physiology—reviewed—it has been used as a sugar alternative in foods in Japan since 1985, in the EU since 2005, in the US since 2006, and in Australia and New Zealand since 2007, besides numerous other countries worldwide where isomaltulose can be found today. Characterization, purity and analytical methods for commercial isomaltulose are laid down for example, in the Food Chemicals Codex. Physical and physiological properties of isomaltulose (Palatinose) have been summarised; its physical properties closely resemble those of sucrose making it easy to use in existing recipes and processes.

生产方法
1.以蔗糖为原料，由非致病微生物中的蔗糖一葡萄糖基果糖变位酶转化后，经浓缩、结晶、分离制得成品。 由优质白砂糖溶解后，用精蛋白杆菌(Protaminobacter rubrum；ACTT No．8457；CBS 574- 低甜度营养性甜味剂。本品安全性高，可被机体利用，但不致龋，与蔗糖并用时还有抑制蔗糖的致龋作用。我国规定可用于糕点、饼干、面包、配制酒、雪糕、冰棍、饮料、糖果、果酱(不包括罐头)，用量按正常生产需要。甜蜜素是较普遍使用的非营养甜味剂。在人体内不被吸收，不产生热量。口感接近蔗糖，常与糖精钠混用，可掩盖糖精钠的苦味。用于酱菜、调味酱汁、配制酒、糕点、饼干、面包、雪糕、冰淇淋、冰棍、饮料等，其最大使用量为０．６５ｇ／ｋｇ；蜜饯，最大使用量为１．０ｇ／ｋｇ；陈皮、话梅、杨梅干等最大使用量８．０ｇ／ｋｇ。
