Recently, some media reported that some Yangmei purchasing points in Longhai District, Zhangzhou City, Fujian Province were found to have violated regulations by soaking preservatives and abusing suspected "three no" sweeteners. According to the investigation, the so-called preservatives used by these merchants are called sodium dehydroacetate and additives such as compound sweeteners. Yangmei has no outer skin protection, high moisture content, and the mature season coincides with high temperature and high humidity climate. The shelf life at room temperature is only 1-2 days. Therefore, the preservation technology of Yangmei is particularly important. The National Standard GB2760-2024 of the People's Republic of China specifies that the addition of sodium dehydroacetate to fresh fruits is prohibited. The reason why these exposed businesses use banned sodium dehydroacetate is that it is odorless and difficult to detect. Doctors warn that these illegal additives may damage the nerves, liver and kidneys, have a particularly significant impact on the development of the adolescent nervous system, and even seriously disrupt the human endocrine system. It is reported that these "soaked Yangmei" were sent to wholesale markets in Zhejiang, Shanghai and other places. In order to cope with supervision, vendors will prepare several boxes of unopened bayberries in advance for marking, and once they encounter sampling, they will send these "clean samples" for inspection. At present, local regulatory authorities have launched special surprise inspections and seized prohibited items on site. Recently, the Market Supervision Bureau of Zhangzhou City, Fujian Province issued a consumer warning for purchasing and consuming Yangmei: risk analysis for consuming Yangmei. Yangmei is a naked fruit that is prone to spoilage. Some operators may illegally add preservatives, saccharin, sodium saccharin, etc. to extend the shelf life and enhance sweetness. Key points for identification: Yangmei, which cannot be aged for a long time, is exceptionally bright, has a sweet to bitter taste, and has a bitter aftertaste, should be highly vigilant. Related regulations: According to the "National Food Safety Standard for the Use of Food Additives", it is strictly prohibited to add saccharin and sodium saccharin to fresh bayberries. Any use beyond the scope or limit is illegal, and the market supervision department will severely investigate and punish it. The common "small white worms" in Yangmei are mostly fruit fly larvae that feed on fruit pulp. The white larval stage is harmless to the human body and is not parasitic. It is not suitable for consumption after maturity and blackening. The higher the sweetness of Yangmei, the more likely it is to attract fruit flies. Proper cleaning can safely remove it. Scientific selection: One look, two smells, three touches to see appearance: the preferred choice is dried and free of water stains on the fruit surface, bright red and natural color, and plump fruit kernels of Yangmei; Do not choose fruits that are unripe, dark red/uneven black red, soft and rotten with water, or abnormally shiny. Smell: Fresh Yangmei has a natural fruity aroma; If there is a smell of alcohol or sourness, it indicates that it has been fermented and spoiled. Do not purchase. Texture: Moderate softness and hardness are optimal; If it is too soft, it is too ripe; if it is too hard, it tends to be sour and astringent. Purchase channels: Choose supermarkets, farmers' markets, and legitimate e-commerce platforms with complete licenses, prioritize purchasing products with promised compliance certificates, keep shopping vouchers, and do not buy bayberries from unknown sources or unlicensed roadside stalls. Standardized cleaning: Soaking in salt water is more reassuring. It is recommended to soak in 5% diluted salt water for 5-10 minutes, which can effectively force out fruit fly larvae and reduce pesticide residues and impurities. After soaking, rinse with flowing water, air dry and consume, which is both safe and retains the original flavor of Yangmei. Proper storage: Fresh consumption is the main option, with refrigeration as a supplement. Yangmei is not resistant to storage and is prone to spoilage at room temperature for 2-3 days. It is recommended to buy and eat it immediately. Do not clean the unfinished waxberries. Blow dry the surface moisture first, seal with plastic wrap, and refrigerate at 0-4 ℃ for no more than 48 hours. After the online purchase of Yangmei arrives, immediately open the box, remove the damaged fruit, and refrigerate it according to the above method to avoid being trapped in the fresh-keeping box and accelerating spoilage. Additive Science Popularization: Legal and Illegal Boundary Sweetener: Sweetness 30-40 times that of sucrose, limited to processed foods such as canned and candied fruits, and strictly prohibited from being added to fresh fruits; Excessive consumption may harm the liver and nervous system, with higher risks for the elderly, pregnant women, and children. Saccharin sodium: has no nutritional value, excessive intake affects digestion and absorption, and reduces appetite; Illegal excessive use threatens health. Compliant food additives are not scary, illegal addition and excessive use beyond the scope and limit are the focus of regulatory crackdown. If citizens discover problems such as spoiled waxberries, peculiar odors, suspected illegal additives, price fraud, etc., they should keep their receipts and samples and promptly call 12315 to complain and report.
