COSTA茶叶保质期标注“100年”

Core Viewpoint - The recent controversy surrounding COSTA's organic Pu-erh tea packaging, which claims a 100-year shelf life, raises questions about food safety and marketing practices in the tea industry [1][3]. Group 1: Product Details - The product in question is COSTA's organic Pu-erh tea (ripe tea), priced at 53 yuan for a net weight of 35 grams, with a production date of October 1, 2025, and an expiration date of October 1, 2125, indicating a shelf life of 100 years [1][3]. - The customer service of COSTA confirmed that the tea can be stored for a long time if kept in proper conditions, but did not provide details on how the shelf life was determined or if there were any experimental certifications [3]. Group 2: Industry Insights - According to food industry analyst Zhu Danpeng, there is currently no unified national standard for the shelf life of tea, and different types of tea have varying standards. Special teas like Pu-erh, black tea, and white tea tend to have longer shelf lives [3]. - Zhu Danpeng expressed skepticism about the 100-year shelf life claim, suggesting it is more of a marketing gimmick and poses significant food safety risks, as improperly stored tea can spoil within decades [3]. - Lin Zhi, director of the Science and Technology Department at the Chinese Academy of Agricultural Sciences Tea Research Institute, stated that the optimal shelf life for Pu-erh tea is around 10 years, and the concept of "the older, the better" only applies within this timeframe [3].
