In the afternoon after the sun shines, a pot of tea, a scent of fragrance, refreshing and spleen - under the hands of people who love tea, drinking tea has become a ritual with a sense of atmosphere and art. For many people, the process of making tea is a process of enjoyment. With the development of the times and the improvement of living standards, drinking tea is not only to meet the needs of people to quench their thirst, but to become a kind of satisfaction to the spiritual world. However, if you want to have a healthy and safe cup of tea, you need to pay attention to the following questions. When drinking tea, many people will have the habit of washing tea, that is, the first soaking water of the tea is poured out, and the first soaking water can wash away the dust, harmful bacteria and other microorganisms and pesticide residues on the tea leaves. In short, the tea is “washed†because the tea is “dirtyâ€. However, at present, in addition to the extraction of tea, it is also dependent on manual work. The mechanization level of China's tea production process is already high, and a large amount of tea can be industrially produced with special machinery. As long as the operation is proper and the production machine meets the national standards, there will be little artificial dust and microbial contamination in the process of producing tea. Even if some microorganisms remain on the tea leaves, it will kill after brewing the tea with hot water of 80 degrees Celsius or higher. Most of the bacteria died. In addition, pesticide residues on tea leaves are also a major concern. China is not only the world's largest tea-growing country, but also has a very complete "national standard for pesticide residues." Therefore, tea that meets relevant national standards can be safely consumed. The first tea should be dumped in the end, depending on the variety of tea: green tea and black tea, which can only be soaked two or three times. If the first bubble is also dumped, it is a pity; Oolong tea, Pu'er The type of tea is pressed, the first tea leaves are not fully stretched, and the tea soup does not reach the drinking standard. At this time, the first soaking water can be used to infiltrate the tea leaves, and then the water is poured out to continue the soaking, so that the tea leaves fully infiltrated and then "wake up" to release the tea fragrance. . Of course, the tea that has been stored for a long time is not in the scope mentioned above. If the tea stored for too long is stored improperly, it is easy to breed mold. If the tea leaves are obviously deteriorated, it is best not to drink. If the sensory odor of the tea leaves does not change much, you can drink it, but it is best to pour the first water when making tea. Many people think that using boiling water to make tea can better stimulate the aroma of tea and make a better drink of tea, but it is not. Boiled tea will destroy the active ingredients such as vitamins. The aromatic oil in the tea will be volatilized, and the tannic acid and theophylline will be leached. The nutritional value of the tea will decrease, the harmful substances will increase, and the tea will lose its fragrance. The suitable tea water temperature is between 80 °C and 90 °C, and should be determined according to the quality of the tea: the tea is tender and the water temperature should be lower; the tea is old and the water temperature can be suitably higher. When preserving tea leaves, pay attention to the four major factors affecting the storage and preservation of tea, namely temperature, humidity, oxygen and light. Temperature - too high a temperature will cause changes in the phenolic substances in the tea, making the aroma of the tea much worse than before. Humidity - Tea is a dry product, and the moisture absorption of the tea is strong. The moderate moderate humidity can keep the tea dry. If the environment is too wet, it will cause the tea to become moist and even moldy. Oxygen - Contact with oxygen can oxidize the aromatic substances in the tea, affecting the fragrance of the tea. Light - long-term exposure to preserve tea leaves will change the color of the tea, while at the same time, the aroma and quality are also reduced. Therefore, the ideal storage conditions for tea storage are low temperature, low humidity, anaerobic and light protection. It should be noted that the packaged tea leaves that are bought are not unpacked and placed directly in the refrigerator for refrigeration. The effect is usually ideal. If frozen, the effect is better. When storing fresh-keeping tea in the refrigerator, it is necessary to prevent the odor from contaminating the tea in the refrigerator; second, the tea has a low water content and must be dry. After the tea is opened, put it into a thick plastic bag as small as possible, and refrigerate it. When you drink it, take out the small bag and brew it. Or put the tea in a tin can or iron can with good sealing and no smell, isolate the oxygen and put it in a dry environment, so that the tea leaves the original fragrance and drink more delicious and safe tea.
