Maltose production in Song and Yuan Dynasties has a long history. It is said that in the late Ming and early Qing dynasties, some people in Caishan and Fang Heng of this town made a living by producing and managing maltose. In 1950s and 1960s, due to the shortage of food, the maltose production in Songyuan stopped for a time, and only resumed after the reform and opening up. Now in Song and Yuan Dynasties, maltose is mainly made by hand in family workshops. According to incomplete statistics, there are about 100 households producing maltose in this town, and the annual production and sales volume is about100000 kg.
The method of making maltose by hand. First, let the wheat sprout. When the buds grow like needles, cut the malt into pieces and mash it. Then, cook a proper amount of rice and mix it with malt. After about eight hours of fermentation, the starch in rice and malt will be converted into sugar. Then juice the fermented rice and malt, boil the juice in a pot, and concentrate the juice into syrup. The syrup that has just been boiled is a red solid, commonly known as "wheat stone". After constant pulling and twisting, it becomes white maltose. Now many producers in the town also mix maltose with black and white sesame, peanuts, ginger juice and other condiments, and refine it into a series of maltose products such as sesame, peanuts and ginger flavor. Although there are many processes and a long time to make maltose, the maltose made in this way is soft and sweet and very popular in the mouth, so Song Yuan has a long history of maltose.
