Why should you use ISO 6079 – Requirements for instant tea in solid form?
Instant tea exhibits a number of variable physical characteristics which can be controlled during manufacture. This variability permits the manufacture of different products to meet the consumers’ needs and tastes. Bulk density and flowability are, for technical reasons, of particular concern to the packer, who is the last party in the chain between the producer and the consumer able to exercise control over the physical characteristics of the product. It is appropriate, therefore, that these characteristics of the product are left for agreement between the supplier and the packer.
ISO 6079 walks you through the chemical characteristics for instant tea in solid form, and provides reference standards for test methods to demonstrate whether your samples meet the requirements.
