--- Changed the "conductive ash content" of the physical and chemical requirements to "ash content" and the corresponding measurement method (see 6:2, 5:2 of the:2009 edition);

--- Added the determination methods "high performance liquid chromatography (external standard calibration method)" and "high performance ion exchange chromatography" for the content of fructooligosaccharides (see 7:3:2, 7:3:3);

--- Deleted the original appendix A, appendix B, appendix C, added appendix A high-performance liquid chromatography determination of fructooligosaccharide standard and samples The chromatogram of the standard and the sample chromatogram of the determination of fructooligosaccharides by high-efficiency ion exchange chromatography in Appendix B, and the chromatogram of the beverage and wine in Appendix C Determination of fructooligosaccharide content (see Appendix A, Appendix B, Appendix C, Appendix A, Appendix B, Appendix C of the:2009 edition): Please note that some content of this document may be patented: The issuing agency of this document assumes no responsibility for identifying patents: This document is proposed and managed by the National Standardization Technical Committee of Food Industry (SAC/TC64): This document is drafted by: Quantum Hi-Tech (China) Biological Co:, Ltd:, Baolingbao Biological Co:, Ltd:, Fengning Ping An Hi-Tech Co:, Ltd: Industry Co:, Ltd:, Fanmi Neng Special Sugar Co:, Ltd:, Shandong Bailong Chuangyuan Biotechnology Co:, Ltd:, Shandong Fuxin Biotechnology Co:, Ltd: Co:, Ltd:, Baiyin Xirui Biological Engineering Co:, Ltd:, Unicon (Beijing) Pharmaceutical Technology Service Co:, Ltd:, China Food Fermentation Industry Research Institute Co:, Ltd:, Perfect (China) Co:, Ltd:, Tiens Group Co:, Ltd:, Shijiazhuang Junlebao Dairy Co:, Ltd:, Beijing Sanyuan Food Co:, Ltd: Co:, Ltd:, Hebei Food Inspection Research Institute, Shanghai Institute of Quality Supervision and Inspection Technology: The main drafters of this document: Liu Ming, Zeng Xianwei, Li Peigong, Qian Xiaoguo, Wei Yuanan, Huang Zhenhua, Dou Guangpeng, Chen Xiaoqiang, Hao Jingfeng, Yang Yun, Li Xiangdong, Cao Mengsi, Wang Xiangyang, Ouyang Daofu, Li Yueqi, Han Meina, Chen Lijun, Zhang Yan, Liu Jie, Wu Changqing, Du Yulan, Wang Yongzhi, Kang Zhiyuan, Zhang Guoyu, Zhu Wei, Wang Haotong, Li Yan, Wang Shijie: The previous versions of this document and its superseded documents are as follows:

---This is the first revision:

With the rapid development of the food fermentation industry, the types of oligosaccharides have been diversified, and the product quality has been improved to a new level: Technology to species have made considerable development and progress: The formulation of GB/T 23528 "Quality Requirements for Oligosaccharides" is the product quality of oligosaccharides: The standardization and standardization of detection methods are the basic work to standardize the industry order of oligosaccharides and related products and promote the development of the industry: GB/T 23528 "Quality Requirements for Oligosaccharides" is proposed to consist of four parts:

--- Part 1: General technical rules for oligosaccharides;

1 Scope

China's national quality requirements for fructooligosaccharide. It is Part 2 of GB/T 23528 and specifies the terms and definitions, the product classification, the requirements, the test methods, the inspection rules and the labelling, packaging, transport and storage. Fructooligosaccharide is a sugar the body cannot digest, and that is the entire point of it. It is a short chain of fructose units attached to a glucose, made either by enzymatic transfructosylation from sucrose or by partial hydrolysis of inulin from chicory or Jerusalem artichoke. Human digestive enzymes cannot break the bond between fructose units, so it passes intact into the colon, where the bifidobacteria and lactobacilli ferment it while most other gut organisms cannot - which is what makes it a prebiotic, and the reason it goes into infant formula, dairy products, functional beverages and supplements. It is also about half as sweet as sucrose with a similar mouthfeel and contributes very few calories, so it does duty as a bulking sweetener. Both claims depend on the same number: the content of the actual oligosaccharides, which is what the product is bought for, against the residual glucose, fructose and sucrose left from the reaction, which are ordinary digestible sugars and which dilute both the prebiotic effect and the low-calorie claim. So the classification is by oligosaccharide purity, and the standard specifies that content and the individual sugars along with the dry matter, the pH, the ash, the colour and transmittance, the heavy metals and the microbiological limits. The distinction between the syrup and the powder forms is carried through, since they are handled and stored differently. Issued on 31 December 2021 and in force since 1 July 2022, it replaces GB/T 23528-2009.

This document specifies the quality requirements for fructooligosaccharides, including terms and definitions, product classification, requirements, test methods, inspection rules and signs, Packaging, transportation and storage: This document applies to the production, inspection and sale of fructooligosaccharides made from sucrose or from plants such as Jerusalem artichoke and chicory:
