Embodiment 1

[0024] A preparation method for fructose syrup, comprising the following steps:

[0025] (1) Get a certain amount of glucose and dissolve it in an appropriate amount of distilled water to prepare a glucose solution with a concentration of 45%;

[0026] (2) Use 10-15% sodium carbonate to adjust the pH to 8.0, add magnesium sulfate, cobalt chloride, and sodium pyrosulfite with concentrations of 0.01mol / L, 0.001mol / L, and 100ppm in the glucose solution, and stir to obtain a mixture ;

[0027] (3) Add glucose isomerase accounting for 1.0% of the glucose mass, perform isomerization reaction for 1 day at 60°C in a water bath, and inactivate the enzyme for 15-20 minutes at 80°C to obtain crude fructose syrup with a fructose content of 42-45%. ;

[0028] (4) Part of the fructose syrup obtained in step (3) is first decolorized by activated carbon accounting for 3‰ of the material volume, and then removed by D001FD cation exchange resin and D354FD anion exchange resin for 30 to 40 min...

Abstract

The invention discloses a method for preparing a fructose-glucose syrup, which comprises the following steps: (1) taking glucose in an appropriate amount of distilled water to prepare a glucose solution; (2) adjusting pH, dissolving magnesium sulfate, cobalt chloride, sodium metabisulfite, and stirring the material uniformly to obtain a mixture; (3) adding glucose isomerase, performing an isomerization reaction at a water bath temperature of 60 to 80 DEG C, and inactivating the enzyme to obtain a crude fructose-glucose syrup; (4) taking some fructose-glucose syrup, decolorizing by activated carbon, performing ion exchange resin impurity removal, performing evaporation, and performing steam sterilization to obtain F42 fructose-glucose syrup; and (5) taking another part of the fructose-glucose syrup, performing chromatogram separating and compounding, then decolorizing the material by activated carbon, performing ion exchange resin impurity removal, performing evaporation, and performingsteam sterilization to obtain the F55 fructose-glucose syrup. The method can improve the quality of the fructose-glucose syrup and reduce the production cost.

Description

technical field [0001] The invention relates to a preparation method of fructose syrup, belonging to the technical field of fructose syrup production. Background technique [0002] High fructose syrup is a product that can completely replace sucrose, and can be widely used in the food and beverage industry just like sucrose, especially in the beverage industry. Its flavor and taste are better than sucrose. The application of fructose syrup in food, beverage and other industries shows its advantages. However, there are still some problems in the existing fructose syrup production process, such as complex production process, low light transmittance of the prepared fructose syrup, low fructose content, and high odor factor content, etc., which all affect the product quality. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a method for preparing fructose syrup capable of improving the quality of fructo...
