Introduction
1. Standard Overview
GB/T 23532-2024 "Quality Requirements for D-Xylose" is a comprehensive revision of the 2009 version of the standard, mainly involving the scope of application, term definitions, physical and chemical indicators and test methods.
2. Comparison table of standard frameworks
| Items | Requirements of the 2009 version | Requirements of the 2024 version |
|---|---|---|
| Scope of application | Applicable only to xylose products | Covering D-xylose and its derivatives |
| Definition of terms | Definition of D-xylose is not clarified | New terms and definitions of D-xylose |
| pH range | 3.5~6.5 | 4.0~7.0 |
| Transmittance determination method | Spectrophotometry | Improved to standard solution comparison method |
3. Explanation of professional terms and practical applications
D-xylose is a right-handed five-carbon aldose made from plants containing polypentose by acid hydrolysis or enzymatic hydrolysis. It is mainly used in the food industry as a flavor enhancer and sweetener.
4. Detailed explanation of detection method
D-xylose content detection: High performance liquid chromatography (HPLC) is used with a differential detector and quantified by the external standard method. This method has the characteristics of high sensitivity and good repeatability.
5. Implementation Suggestions
Enterprises should focus on the following aspects:
- Raw material quality control: Ensure that the purity and impurity content of raw materials such as corn cobs and sugarcane bagasse meet the requirements.
- Production process optimization: Use advanced enzymatic hydrolysis technology and purification equipment to improve the efficiency of D-xylose extraction.
- Quality monitoring system: Establish complete laboratory testing capabilities to ensure that all indicators meet national standards.
- Packaging and storage: Follow the requirements of GB/T 191 to prevent products from being damp and contaminated.
