Foreword

GB/T 9833 "Pressed" is divided into nine sections.

--- Part 1. Flower brick tea;

--- Part 2. black brick;

--- Part 3. Fu tea;

--- Part 4. Kang brick tea;

--- Part 5. Tuocha;

--- Products regardless of grade, sensory quality and physical and chemical indicators merger;

--- Deleting physical and chemical indicators in Note 1, the physical and chemical indicators of water extracts and coronoid scattered capsule bacteria to determining indicators;

--- Health indicators using GB 2762 "contaminants in food limited", GB 2763 "national food safety standards for pesticides in food Maximum Residue Limits "and GB 26130" food paraquat and other 54 kinds of pesticide maximum residue limits "requirement, instead of defunct GB 9679-1988 "tea health standards";

--- Judgment rule to the sensory quality of the provisions of chapter 4, physical and chemical indicators, health indicators and net content project requirements, any one of irregularities Lattice products are as unqualified products. This part is proposed by the China Federation of Supply and Marketing Cooperatives. This part of the National Technical Committee of Standardization Tea (SAC/TC339) centralized.

1 Scope

Part 3 of China's national standard for compressed tea, covering fu zhuan or fu brick tea. Fu brick is the most technically interesting of the Chinese dark teas, because its production includes a step no other tea has: fahua, the deliberate flowering, in which the pressed brick is held for days under controlled temperature and humidity so that Eurotium cristatum grows through it and covers the interior with golden spores. The process was originally accidental, discovered in the bricks that travelled slowly and damp along the trade route to the northwest, and it was industrialised in the twentieth century once it was understood. The fungus consumes some of the tea's catechins and produces the sweet, mellow, distinctly non-astringent character that fu brick is drunk for, and a brick with sparse or absent flowering is downgraded. Cultivating a specific fungus in a food product at scale is exactly why the requirements need to be written down. This part specifies the requirements, test methods, inspection rules, marking, labelling, packaging, transport, storage and shelf life for fu brick tea.

GB/T 9833 provisions of this part of the Fu brick requirements, test methods, inspection rules, marking, labeling, packaging, transportation, storage and security Shelf. This section applies to black raw tea leaves as the main raw material, through Maocha screening, blending semi-finished products, pile, steam pressing, blur, dried Product packaging and other processes made of brick tea Fu.
