I am working on section 2.3.1 Product Development and Realization for Module 2 Level 2 - SQF Standard. The company I work for does not create products but blends together existing products/ ingredients of Camellia Sinensis. The facility is a tea blending and packaging process. I have been debating, and trying to do my own research, but I would like to know if dry tea has a shelf life. From my research I was able to find that opinions vary but no estimations are less than 6 months and some are as long as 2 years. I know everything depends on how it is storage to preserve it, but I would like to know if there is any way I can validate it. I do know that as an internal practice, if tea is in storage for more than 3 years, it is retested for microbiological levels results.
Please feel free to share your thoughts.
Thank you in advance,
