Tea Testing

The "physical and chemical indicators" of tea refer to the physical properties, physical properties, chemical composition, chemical properties, chemical properties, and other technical indicators of tea, which are also its quality indicators. The most common of them are water extract, ash, and crude fiber, which are essential physical and chemical indicators of tea and can, to a certain extent, reflect the quality of tea. The quality of the semi-finished tea directly determines the quality of the finished tea. Therefore, before the tea is blended, the physical and chemical inspection of the semi-finished tea must be carried out, which is a vital link to ensure the quality of the finished tea. Tea physical and chemical testing is also critical for product registration, helping to ensure that only safe and compliant products are placed on the market. Accurate and verifiable safety and quality data simplifies the compliance process.
