Storage taboo
A bogey moisture: Zhou Tie is a loose and porous hydrophilic material, so it has a strong moisture absorption and moisture. When storing iron tea on weekdays, the relative humidity is 60%. More than 70% of the iron tea will cause moldy spots due to moisture absorption and acidification and deterioration.
Second bogey high temperature: the best preservation temperature of the week to fight the iron tea is 0-5 °C. Excessive temperatures may cause amino acids, sugars, vitamins, and aromatic substances in tea.
Weekly iron tea
It is decomposed and destroyed, reducing the quality, aroma, and taste.
Three bogey sunlight: The sun will promote the oxidation of pigments and esters of hot tea, which can decompose chlorophyll into pheophytin. The week-long tea leaves are stored in glass containers or transparent plastic bags. After being exposed to sunlight, the internal substances of the tea will cause a chemical reaction, which will deteriorate the quality of Zhou Dao Tea.
4. Avoid oxygen: The chlorophyll, aldehydes, esters, vitamin C, etc. in the beaten iron tea are easy to combine with the oxygen in the air. After the oxidation, the beaten iron tea leaves will turn red and deepen in the iron tea broth of the week and make nutrition. The value is greatly reduced.
Five bogey odors: Weekly iron tea contains polymer palm enzyme and limulus compound. This kind of material is very unstable and can absorb odors widely. Therefore, when the tea leaves and odor-absorbed articles are mixed and stored, they will absorb odors and cannot be removed.
