High fructose corn syrup is a sweetener made from starch hydrolysis isomerization. Its main components are fructose and glucose, so it is called high fructose corn syrup. Because corn starch is mostly used, it is also called corn syrup. The sweetness of fructose syrup mainly depends on fructose. The higher the fructose content, the sweeter the syrup. Because of its stable nature, reasonable sweetness and ultra-low cost, it is widely used in all kinds of drinks and foods that need to add sugar or sweetness.
