And thirdly, the liquid glucose has high hygroscopicity, and can be used in soft sweets, bread and pastry foods to keep the softness of the products, improve the taste of the products and prolong the shelf life. And fourthly, the liquid glucose has the advantages of crystallization resistance, low freezing point and the like, and can improve the taste and the quality of the product when being used for cold drink production. And the liquid glucose has high osmotic pressure and higher sweetness, so the liquid glucose is used as a sweetening agent for preserved fruits, jam, fruit juice cans and cream foods, and has the advantages of long quality guarantee period, difficult change of product taste and the like. And sixthly, the application of the liquid glucose in the baked food: the liquid glucose has good reducibility, low chemical stability under neutral and alkaline conditions, is easy to decompose to generate colored substances when being heated, is also easy to have coking reaction with protein nitrogen-containing substances to generate brown yellow caramel, has special flavor, and is beneficial to food fermentation in the baking industry due to higher fermentable sugar content. The liquid glucose has high moisture absorption and moisture retention, and can make baked food keep constant moisture, and is soft and delicious. And seventh, the liquid glucose has the function and the use similar to high maltose syrup in the application process, and can be prepared according to the requirements of customers (the maltose content of the liquid glucose is lower by about 10% -30%).

The mode of heat evaporation is adopted in the processing of present glucose syrup, with unnecessary moisture separation in the magma, obtains the higher syrup of purity, and the efficiency of moisture separation has directly influenced the efficiency of processing, and equipment improvement evaporation efficiency is the direction of an important improvement machining efficiency.
