摘　　要：高果糖浆和结晶果糖具有独特的风味,是食品和饮料常用的甜味剂。以原糖作为原料生产高果糖浆和结晶果糖,可增加蔗糖产品的多样化,提高蔗糖的市场竞争力。原糖水解条件优化,为降低5-羟甲基糠醛的生成量和糖浆的色度,在保证达到水解程度的前提下,考察水解pH值、时间和温度3个参数对糖浆副产物生成量的影响,最后确定操作条件:水解pH值为2.0±0.1,水解时间为(30±5)min,加热温度为90～93℃,获得较好的水解效果,使5-HMF的生成量最少,果葡糖浆色度的增值最低。High fructose syrup and crystalline fructose have unique flavor and are the sweeteners commonly used in food and beverage. The production of high fructose syrup and crystalline fructose with raw sugar as the raw material can increase the diversification of sucrose products and improve the market competitiveness of sucrose. Optimize the hydrolysis conditions of raw sugar, in order to reduce the amount of 5-hydroxymethylfurfural and syrup chromaticity, on the premise of guaranteeing the degree of hydrolysis, the effects of pH, time and temperature on the byproduct generation quantity of syrup are investigated. Finally, the operating conditions are as follows: the hydrolysis pH is 2.0± 0.1, the hydrolysis time is (30±5) min, the heating temperature is 90~93 ℃, the better hydrolysis effect is obtained, the amount of 5-HMF is the least, and the fructose syrup has the lowest increase in chromaticity.
