High fructose corn syrup (HFCS) is a kind of starch sugar crystal made by hydrolysis and isomerization of vegetable starch.
It is a colorless viscous liquid with good fluidity and odorless at room temperature. High fructose corn syrup is mainly composed of glucose and fructose.
According to the fructose content, high fructose corn syrup can be divided into three categories: the first generation high fructose corn syrup contains 42% fructose;
Second generation fruit high fructose syrup contains 55% fructose; Third generation high fructose syrup contains 90% fructose.
The sweetness of HFCS was positively correlated with the fructose content, and the sweetness of the third generation HFCS could be achieved by using a small amount in food
