茶叶保质期100年？专家：既无科学依据也不合法

Core Viewpoint - A well-known chain coffee brand has labeled its organic Pu-erh tea with a 100-year shelf life, causing confusion among consumers regarding the validity of such a claim [1][4]. Group 1: Shelf Life and Storage Conditions - The shelf life of tea is not a fixed value and depends on the type of tea and storage conditions [3]. - For post-fermented teas like Pu-erh, the national standard GB/T 22111-2008 states that they are suitable for long-term storage under proper conditions, but this does not equate to an indefinite shelf life [3]. - The optimal shelf life for Pu-erh tea is around 10 years, with quality improving over time within this period [3]. Group 2: Legal and Regulatory Aspects - The labeling of a 100-year shelf life is deemed illegal and lacks scientific support according to legal experts [4]. - The Product Quality Law mandates that product labels must be truthful, and businesses are responsible for the accuracy of such claims [4]. - There is currently no scientific method to verify that tea can be stored for 100 years without degradation [4]. Group 3: Consumer Rights and Recommendations - Consumers can seek redress by contacting the seller for explanations regarding the 100-year shelf life claim and may request refunds if unsatisfied [5]. - If the seller refuses to comply, consumers can file complaints with consumer associations or market supervision departments [5]. - It is advised that consumers focus on clear labeling of production dates, storage conditions, and standards when purchasing tea, rather than being misled by claims of extended shelf life [5].
