Analysis of key technical requirements
The standard stipulates that the moisture content must be ≤7.0%, the water extract must be ≥32.0%, and the powder content must be controlled at ≤1.0% to ensure the tea's stable quality. Hygiene indicators must strictly adhere to the limits for pollutants and pesticide residues set out in GB 2762 and GB 2763.
Recommendations for Standard Implementation
Manufacturers should establish a three-tiered quality control system:
1. Fresh leaf incoming inspection
2. Moisture control during processing
3. Comprehensive inspection of finished products before shipment
It is recommended to equip basic testing equipment such as a moisture meter and a UV spectrophotometer.
Technological Evolution Analysis
Compared with the old version of the standard, the 2019 version has the following major improvements:
- Refinement of the sensory indicators for the Golden Bud grade
- Addition of a lower limit requirement for water extractables
- Strengthening of pesticide residue monitoring items
