How do ordinary families store tea
First: The five main elements of Tong tea storage (humidity, light, oxygen, peculiar smell, high temperature)
1. Humidity is the most important, because humidity determines food safety to a large extent. Once the moisture content is too high, the problem is not only the problem of tea deterioration, but also the growth of toxins and affect health.
2. Light is very easy to cause deterioration of tea. Accelerating light will cause many substances in tea to have photosensitivity reactions, such as fading, condensation, and photolysis, which will quickly reduce the quality of tea.
3. Oxygen is very easy to cause the oxidative condensation reaction of tea, which reduces the freshness, and the condensation of small molecules into large molecules will also reduce the tea soup
The extract makes the taste thinner.
4. Peculiar smell, because of the special loose and porous structure of tea, it is easy to absorb peculiar smell.
5. High temperature and high temperature will also affect the deterioration of tea, especially red and green tea, some green tea, high temperature with high humidity, high oxygen environment, will accelerate the deterioration of tea.
Second: storage requirements for different teas
In fact, most teas can be stored in a hypoxic environment, sealed, protected from light, and isolated from odors. So for some teas that need to be aged under certain conditions, in fact, there is no problem with the first four points. Some people may wonder whether insufficient oxygen will make the microorganisms of dark tea disappear? In fact, most of the microorganisms transformed in the later stage of dark tea, They are all anaerobic bacteria, and the low oxygen environment will not hinder their microbial fermentation pathways
It can also reduce the oxidation condensation reaction (because the advantageous advantages of short-term oxidation in the long run are obvious, and the increase in the oxidation condensation reaction in the long run will only make the tea soup light and tasteless)
Therefore, for those who want to reach the drinking period quickly, the temperature requirements may not be so strict, but for those who want to store for a long time, the temperature should not be too high.
Generally, it is recommended that the relative humidity of the air be above 40% and below 70%. Different teas require different requirements. If the humidity is above 80%, pay attention to moisture.
