Starch sugar (containing glucose syrup, maltose syrup, high fructose syrup containing 42% fructose, high fructose syrup containing 55% fructose, and medical crystalline glucose, etc.) is the product with the largest starch deep processing output. It is mainly a food additive, and it is also an industrial raw material. It is used as a raw material for downstream products, such as glucose, maltose, and high fructose syrup. These are all used in food, and starch sugar can be made into sorbitol and amino acids. This is also the upstream raw material of downstream products, and the demand in this regard is also quite large. Compared with sucrose, starch sugar is still very competitive in terms of health care, practicality and cost, and this space is still very large.
