Outline
To analyze the distribution characteristics, usage patterns and exposure contribution via beverage consumption of sweeteners in beverages sold around school campuses from the perspective of beverage category segmentation.
A total of 834 samples from 7 beverage categories, including flavored beverages, were randomly collected. The content of 4 kinds of sweeteners (sodium saccharin, acesulfame potassium, aspartame and neotame) were determined using high performance liquid chromatography (HPLC). Compliance with sweetener usage was evaluated according to the GB 2760—2014 National food safety standard-Standard for the Use of Food Additives and differences among categories were analyzed using the chi-square test.
Special purpose beverages had the highest non-compliance rate (14.7%, 14/95), followed by flavored beverages (14.6%, 36/247), both being higher than that of coffee beverages (0%, 0/15). The rate of unauthorized use of sodium saccharin in flavored beverages was (9.3%, 23/247) (its use was prohibited in beverages according to the standard). The exceedance rate of neotame in special purpose beverages was (10.5%, 10/95).
There are significant category-specific variations in sweeteners non-compliance in beverages around school campuses: Flavored beverages are the key category for the unauthorized use of sodium saccharin, while special purpose beverages are the high-risk category for neotame exceedance. It is recommended that quarterly targeted sampling and inspection be implemented for these 2 kinds of beverage categories, along with enhanced supervision of sweetener usage compliance, so as to provide direct scientific support for targeted regulation of beverages around school campuses and health risk warning for adolescents.
