首先告诉朋友们茶叶的保质期和茶叶的品种有直接的关系,例如普洱的保质期大概是10~20年左右。


比如说绿茶它在常温的情况下可以保存一年左右,一般盒子上面会标明是18个月,也就是一年半。




茶叶过期了到底还能不能喝


1、茶叶一般都是干燥为主的,过期的茶叶基本都会受潮失去本质口感。没有健康价值了。就会变苦变涩等。


2、里面会产生很多细菌,影响身体健康,尤其是黄曲霉菌,会对肝脏产生伤害。


如何判断茶叶已变质



1.辨颜色,比如绿茶的颜色是嫩绿或墨绿,若出现黑点,灰白色等类似霉点,就已经发霉变质了。


2.闻气味,没有变质的茶叶会有一股淡淡的茶香,已经发霉的茶叶会有一股霉味。另外出现焦味,烟味,酸馊味等异味。


3、看汤色,茶汤的颜色会变得浓暗。则需要多加注意。如果是绿茶会变红。


4、看形状,不再紧直标准,而是吸水后的疏松潮湿样。


5、品茶味,过期茶叶口感不再醇厚鲜爽,滋味浓度下降。


大多数茶叶一不小心就会过期,平时我们在保存茶叶的时候一定要用对方法,把茶叶密封放在通风干燥的地方,长时间不泡还需要定期拿出来晒太阳,这样才可以更好地保存茶叶。

First, tell friends that the shelf life of tea is directly related to the variety of tea. For example, the shelf life of Pu'er is about 10-20 years.


For example, green tea can be stored for about one year at room temperature. Generally, the box will indicate 18 months, which is one and a half years.

Can the tea be drunk after it expires?


1. The tea is generally dry, and the expired tea will basically lose its essential taste after being damp. There is no health value anymore. It will become bitter and astringent.


2. There will be many bacteria in it, which will affect your health, especially the Aspergillus flavus, which will cause damage to the liver.


How to tell if tea has deteriorated



1. Identify the color. For example, the color of green tea is tender green or dark green. If there are black spots, off-white spots and similar mould spots, it has become moldy and deteriorated.


2. Smell the smell, the tea leaves that have not spoiled will have a faint tea fragrance, and the moldy tea leaves will have a musty smell. In addition, peculiar smells such as burnt smell, smoke smell, and sour smell appeared.


3. Look at the color of the soup, the color of the tea soup will become darker. You need to pay more attention. If it is green tea, it will turn red.


4. Looking at the shape, it is no longer a straight standard, but a loose and moist appearance after absorbing water.


5. Taste the taste of tea, the taste of expired tea leaves is no longer mellow and refreshing, and the taste concentration decreases.


Most tea leaves will expire accidentally. Usually we must use the right method when preserving the tea. Seal the tea in a ventilated and dry place. If it is not soaked for a long time, it needs to be taken out in the sun regularly, so that it can be better. Preserve the tea leaves.
