Introduction

With the rapid development of food fermentation industry, the types of starch sugar are diversified, the product quality is improved to a new level, and the industry has made great progress from technology to category. GB/T 20882 Quality requirements for starch sugar is the standardization and normalization of product quality and test methods for starch sugar, and is the basic work to standardize the industrial order of starch sugar and its related products and promote industrial development.

GB/T 20882 consists of the following seven parts under the general title Quality requirements for starch sugar:

——Part 1: Edible dextrose;

——Part 2: Glucose syrup and glucose syrup powder;

——Part 3: Crystalline fructose and solid fructose-glucose;

——Part 4: High fructose syrup;

——Part 5: Maltose;

——Part 6: Maltodextrin;

——Part 7: Trehalose.
