茶叶保质期标注“100年”？知名品牌回应

Core Viewpoint - The recent controversy surrounding COSTA's organic Pu'er tea product, which claims a shelf life of 100 years, raises questions about food safety and marketing practices in the tea industry [1][7]. Group 1: Product Details - Consumers reported that the packaging of COSTA's organic Pu'er tea indicates a production date of October 1, 2025, and an expiration date of October 1, 2125, suggesting a shelf life of 100 years [1]. - The product is priced at 53 yuan for a net weight of 35 grams, with the detail stating that under proper storage conditions, Pu'er tea is suitable for long-term preservation [3]. Group 2: Expert Opinions - Food industry analyst Zhu Danpeng noted that there are no unified national regulations on the shelf life of tea, and while certain teas like Pu'er may have longer shelf lives, improper storage can lead to spoilage and food safety risks [7]. - Zhu also criticized the 100-year shelf life claim as a marketing gimmick, stating that even teas stored for decades can deteriorate significantly [7]. - Lin Zhi, director of the Tea Research Institute of the Chinese Academy of Agricultural Sciences, stated that the optimal shelf life for Pu'er tea is around 10 years, and the concept of "the older, the better" only applies within this timeframe [7]. Group 3: Legal Perspectives - Lawyer Chen Yanhong highlighted that while there is a consensus that Pu'er tea can be stored long-term, the claim of a 100-year shelf life lacks scientific validation and exceeds safe limits for food products [9]. - The labeling of the product may mislead consumers regarding its preservation period, potentially violating laws that require food labels to be truthful and accurate [9].
