Problems solved by technology

The traditional method of producing fructose syrup is to prepare starch into starch milk, add amylase to liquefy by high-temperature spraying, then add glucose glucoamylase to convert it into glucose, remove protein through vacuum drum or plate frame filtration, add activated carbon once for decolorization, and pass through One-time ion exchange to remove impurities, pre-concentration, immobilized isomerase isomerization, and then secondary decolorization with activated carbon, secondary ion exchange, evaporation and concentration to obtain fructose syrup. This method has high production costs and energy consumption. We have designed a fructose syrup made from plant starch hydrolysis and isomerization to solve the above problems

Embodiment 1

[0018] A preparation method of fructose syrup made by plant starch hydrolysis and isomerization, comprising the following steps:

[0019] S1, plant starch hydrolysis: put plant starch into a container, add amylase, heat up to 100°C, and stir for 10 minutes to fully hydrolyze plant starch, and then liquefy at high temperature to obtain liquefied products;

[0020] S2, saccharification: filter and remove slag from the liquefied product obtained in S1, and add glucose enzyme to carry out saccharification reaction. The saccharification time is 18 hours. The saccharified product is filtered through organic membrane, first ion exchange and first decolorization filtration Finally, the final saccharification product was obtained, and activated carbon was used to decolorize for 40 minutes during decolorization;

[0021] S3, isomerization: adding glucose isomerase to the saccharification product obtained in S2 to convert part of the glucose into fructose to obtain a mixed solution A;

Abstract

The invention discloses a preparation method of high fructose corn syrup prepared through plant starch hydrolysis and isomerization. The preparation method includes the steps of S1, plant starch hydrolysis; S2, saccharification; S3, isomerization; S4 evaporation and concentration. The preparation method has the advantages that a pre-concentration procedure is omitted, energy is saved, and cost issaved; an organic membrane is used for filtering, and a decoloring effect is increased by the filtering coordinated with two subsequent activated-carbon decoloring; reaction conditions are controlledstrictly, and the prepared high fructose corn syrup is good in color and taste and high and stable in quality.

Description

technical field [0001] The invention relates to the technical field of fruit grape pulp, in particular to a method for preparing fructose syrup prepared by hydrolyzing and isomerizing plant starch. Background technique [0002] High fructose syrup is a starch sugar crystal made by hydrolysis and isomerization of plant starch. It has a unique flavor and is an important sweetener. Because its composition is mainly fructose and glucose, it is called "fructose syrup". The traditional method of producing fructose syrup is to prepare starch into starch milk, add amylase to liquefy by high-temperature spraying, then add glucose glucoamylase to convert it into glucose, remove protein through vacuum drum or plate frame filtration, add activated carbon once for decolorization, and pass through One-time ion exchange to remove impurities, pre-concentration, immobilized isomerase isomerization, and then secondary decolorization with activated carbon, secondary ion exchange, evaporation ...
