Core Viewpoint - The new 2025 version of the "General Standard for Nutrition Labeling of Prepackaged Foods" will include "sugar" as a mandatory labeling item, leading to increased demand for analysis and testing technologies, thereby driving upgrades in analytical testing capabilities [1][2]. Group 1: Expansion of Testing Items and Scope - The new standard expands the mandatory labeling content from "1+4" to "1+6," adding saturated fat and sugar, and requires the labeling of trans fatty acids when hydrogenated oils are used [4]. - The new standard specifies that the sugar content refers to the sum of fructose, glucose, sucrose, maltose, and lactose, necessitating quantitative testing for foods that previously did not require sugar content detection [4]. - The allowable error range for sugar is strictly defined as "measured value ≤ 120% of the labeled value," which raises the accuracy and repeatability requirements for testing methods [4]. Group 2: Upgrading Testing Methodologies and Technical Adaptation Pressure - The new standard necessitates the adoption of updated testing methods for sugars and fatty acids, with the introduction of GB 5009.8-2023, which replaces previous standards and will be implemented on March 6, 2024 [6]. - The updated methods include four testing techniques: high-performance liquid chromatography, ion chromatography, acid hydrolysis-Rhein method, and Rhein method, each suitable for different food matrices [6][7][8]. - The revision of GB 28050 not only standardizes food labeling information but also serves as a comprehensive test of the analytical testing industry's technical capabilities, requiring timely upgrades of software and hardware by testing institutions during the two-year transition period [9].
