安溪铁观音中富含儿茶酚等多酚类化合物,对于改善心血管健康有一定益处。美国普渡大学研究发现,在绿茶中加入一些富含维生素C的柑橘类食物如柠檬等,能提高人体对儿茶酚的吸收效率,可使儿茶酚的保健功效增加4倍。


黑茶因外观为黑色而得名,其中富含的黄酮类物质对心脏有一定的益处。2012年美国《预防》杂志曾推荐,每天喝3杯黑茶能将高血脂风险降低36%。但是,这其中也含有14~70毫克的咖啡因,如果患者血压较高或者心率过快则应慎用。


一、发酵型铁观音的保质期


铁观音多数是经过轻发酵的,所以保持期不会太久,一般在三个月左右,最好在一到二个月喝完,但如果是真空密封保存在3-5度的温度下,保质期长达两年,如果再拿到常温下就要尽快喝完。


二、烘焙型铁观音的保质期


经过高温烘焙过的铁观音存放时间会延长很久,甚至可以放上十年、二十年以上,可以存成老茶后再喝。在福建民间,就有把茶放在柚子皮里存成老茶的传统,最后将柚子皮和铁观音老茶一起冲泡,制成清热解暑的凉茶饮用。




三、真空包装铁观音的保质期


市面上买的铁观音采用真空压缩包装法,一般只需放置在阴凉处,避光保存就可以保存比较长的时间,如果能放在零下5度的冰柜里保存,效果更好,不过不是建议不要超过一年,半年内喝完最好。


铁观音的保质期是多久,现在你了解了吗?简单地说,轻发酵的铁观音保质期比较短,陈放后风味也会有所损失。而烘焙型的铁观音保存时间则变长了很多,可以陈放。如果要轻发酵铁观音的保质期延长,最重要的还是放在干燥、避光、阴凉处进行保存。

Green tea is rich in polyphenolic compounds such as catechol, which has certain benefits for improving cardiovascular health. Purdue University in the United States found that adding some vitamin C-rich citrus foods such as lemons to green tea can increase the body's absorption efficiency of catechol and increase the health benefits of catechol by 4 times. Dark tea is named for its black appearance, and its rich flavonoids have certain benefits for the heart. In 2012, the US "Prevention" magazine recommended that drinking 3 cups of black tea a day can reduce the risk of hyperlipidemia by 36%. However, this also contains 14 to 70 mg of caffeine, which should be used with caution if the patient's blood pressure is high or the heart rate is too fast.


1. The shelf life of fermented Tieguanyin


Tieguanyin is mostly lightly fermented, so the retention period will not be too long, usually about three months, it is best to drink it in one to two months, but if it is vacuum sealed and stored at a temperature of 3-5 degrees, The shelf life is as long as two years. If you get it at room temperature, you must drink it as soon as possible.


2. The shelf life of roasted Tieguanyin


The storage time of Tieguanyin that has been baked at high temperature will be extended for a long time, and it can even be stored for more than ten or twenty years, and it can be stored as old tea before drinking. In Fujian folks, there is a tradition of storing tea in grapefruit peels as old tea. Finally, the grapefruit peels and Tieguanyin old tea are brewed together to make herbal tea for clearing heat and relieving heat.




Third, the shelf life of vacuum packaging Tieguanyin


Tieguanyin bought on the market adopts the vacuum compression packaging method. Generally, it can be stored for a long time if it is stored in a cool place and protected from light. If it can be stored in a freezer at minus 5 degrees, the effect will be better, but it is not recommended. Do not exceed one year, it is best to finish drinking within six months.


How long is the shelf life of Tieguanyin? Do you know now? Simply put, the shelf life of lightly fermented Tieguanyin is relatively short, and the flavor will be lost after aging. The baking-type Tieguanyin has a much longer storage time and can be aged. If you want to extend the shelf life of lightly fermented Tieguanyin, the most important thing is to store it in a dry, dark, and cool place.
