Introduction

With the rapid development of food fermentation industry, oligosaccharide types have diversified, product quality has been improved, and product varieties have been enriched.

The industry has made great progress in technology and development. GB/T 23528 "Quality Requirements for Oligosaccharides" was formulated to improve the product quality and The normalization and standardization of detection methods is the basic work to regulate the industry order of oligosaccharides and related products and promote industrial development.

GB/T 23528 “Quality Requirements for Oligosaccharides” is planned to consist of four parts.

— Part 1: General. The purpose is to improve the product quality of the oligosaccharide industry.

— Part 2: Oligofructose. The purpose is to improve the product quality of the oligofructose industry.

— Part 3: Xylo-oligosaccharides. The purpose is to improve the product quality of the xylo-oligosaccharides industry.

— Part 4: Isomaltooligosaccharides. The purpose is to improve the product quality of the isomaltooligosaccharides industry.
