摘　　要：淀粉糖是食品工业中常用的甜味剂,用于食品、饮料和药品等领域。液化和糖化工艺是淀粉水解制糖的基本过程,液化后的多糖在复配糖化酶的作用下被完全水解为葡萄糖。影响淀粉水解效率的因素很多,包括淀粉质量、液化温度、酶制剂、工艺条件等。提高淀粉转化的效率是生物化工和发酵工程等行业生产技术提升的重要目标。本研究聚焦淀粉糖的糖化工艺,研究并对比了生产中不同工艺条件下糖化液中多糖组分的变化规律和各组分之间的关系,明确了难降解的杂糖成分和含量。结果表明:糖化酶对多糖和二糖的催化呈现出完全同步现象,杂糖中的三糖主要是潘糖,先进的液化工艺有助于减少糖化液中的杂糖。研究阐明了葡萄糖转化过程中各种组分的转化规律和趋势关系,初步揭示了葡萄糖与寡糖之间的酶动力学关系,生产中以减少杂糖为管理目标,有助于生产效率提升。本研究结果对淀粉糖生产型企业技术提升有一定指导意义。Corn syrup is a commonly used sweetener in the food industry and is used in food,beverage and pharmaceutical fields.Liquefaction and saccharification are the basic processes of starch hydrolysis.The oligosaccharide is completely hydrolyzed to glucose under the catalysis of glucoamylas.There are many factors affecting the efficiency of starch hydrolysis,including starch quality,temperature,source and property of enzyme,process condition and so on.Improving the efficiency of starch is one of the important goals of production technology of biochemical and fermentation engineering industries.In this study,focusing on the saccharification process of starch sugar,the change process of polysaccharide components and the relationship between components in the saccharification solution under different process conditions of industrial production were studied,and it was found that the panose existed and was difficult to degrade.This paper showed that the catalysis of glucoamylase on polysaccharide and disaccharide was synchronous.Improving the efficiency of liquefaction proved helpful to promote the productivity of saccharification.The transformation pattern and the relationship of various components in the process of glucose transformation were explored;The enzyme kinetic between glucose and oligosaccharide was far more complex and need be further studied;The production should focuses more on the generation of panose,which would help to improve the starch conversion efficiency.This study has guiding significance for the technology improvement of starch sugar production plants.
