Method for preparing high-purity maltose syrup by adopting rice as raw material

Abstract

The invention discloses a method for preparing high-purity maltose syrup by adopting rice as raw material, comprising the following steps of: (1) removing the impurity in the raw material rice, adding water for soaking, grinding the syrup into grout, and filtering; (2) mixing the grout, adding high temperature-resistant Alpha amylase, stirring and mixing evenly; (3) carrying out liquefaction and discharging slag; (4) saccharifying; (5) neutralizing, decoloring and filtering; (6) carrying out ion exchange refining; (7) concentrating; and (8) packaging. The obtained dried high-purity maltose syrup has the maltose content of 80 to 86%.

Description

technical field

[0001] The invention relates to a method for preparing maltose syrup, in particular to a method for preparing high-purity maltose syrup from rice. Background technique

[0002] my country's current sucrose production is relatively large, with an annual output of about 10 million. However, excessive intake of sucrose is also more harmful to the human body. With the continuous improvement of people's living standards, the requirements for food quality are also getting higher and higher. The development of new sugar products with rich nutrition, good taste, low calorific value and good processing performance and their preparation methods has become a research hotspot in the world. The preparation method of starch sugar is one of the research hotspots.

[0003] Starch sugar series products mainly include maltose, isomerized maltose, glucose, fructose syrup, maltodextrin, glucose and oligosaccharides (trisaccharides, tetrasaccharides, etc.). Starch sugar has t...
