Melon is a sticky sugar made of yellow rice and malt. The candy that is drawn into a long strip is called "Guandong Sugar", and the candy that is drawn into a flat circle is called "honeydew melon". Put it outside in winter, because the weather is very cold. The honeydew melon is solid with some tiny bubbles in it. It tastes crisp and sweet, and has a unique flavor.

In the past, after the twentieth day of the twelfth lunar month, children sang the above ballads, hoping that adults would buy honeydew melons quickly. This sticky maltose was recorded in Jin Dynasty's Chronicle of Jingchu, which was called "gum" (sound shape) at that time.

Brief introduction of maltose

Maltose is a colorless crystal, usually containing one molecule of crystal water. Melting point 102℃, easily soluble in water, and the sweetness is 40% of sucrose. There are two isomers, α -and β-,and the ratio of α -and β -maltose in aqueous solution is 42:58. The molecular formula of crystalline β -maltose containing one molecule of water is β-c12h22o11H2O. If crystal water is removed, β -maltose will be converted into α-maltose, so it is not easy to obtain anhydrous β -maltose.

Commercially available crystalline maltose is mainly hydrous β-maltose, of which 5%- 10% has been converted into α-maltose. Maltose can be made into maltose syrup, which is widely used. Used in various fields of food industry, such as solid food, liquid food, frozen food, colloidal food (if frozen) and so on. Mainly used for processing caramel sauce color, candy, fruit juice beverage, wine making, canned food, bean paste and soy sauce.
