Problems solved by technology

The industrial production of fructose syrup and glucose is currently mainly obtained from starch as raw material through liquid saccharification and refining. Due to the difference in production process, the two products are usually produced by two independent production lines, and the production cost is relatively high. here comes some difficulty

Abstract

The invention provides a method of producing high fructose corn syrup and glucose in a same production line. A certain amount of glucose syrup is added into a mother liquor so that the mixture can meet the requirements of monosaccharide components of F42 high fructose corn syrup; the mixture is subjected to isomerization so as to convert glucose into fructose after isomerization; and then discoloring, ion exchanging, concentrating, and packaging are performed to produce F42 fructose syrup. A conventional glucose production technology is optimized, a high concentration liquefying production method is adopted; high fructose corn syrup and glucose are co-produced; the byproducts of glucose are recovered and reutilized; investment, water resources, and energy are saved, and energy saving and emission reduction are realized.

Description

technical field [0001] The invention relates to the field of syrup preparation, in particular to a simultaneous production process of fructose syrup and glucose. Background technique [0002] Fructose syrup is mainly composed of glucose and fructose. According to the fructose content, fructose syrup is divided into three categories: the first generation fructose syrup (F42 type) contains 42% fructose; the second generation fructose syrup (F55 type) contains 55% fructose; the third generation fructose syrup (F90 type) type) containing 90% fructose. The sweetness of fructose syrup is positively correlated with the fructose content, and the third-generation fructose syrup can be used in a small amount in food to achieve a certain sweetness. Since the sweetness of fructose syrup is comparable to that of sucrose and has its own characteristics, its application field is wider than that of sucrose; it is not only widely used in food industry and health food, but also in pharmaceu...
