Why does the milk tea shop prompt "drink within 2 hours"

Recently, the Shanghai Municipal Consumer Protection Committee has been more serious about the question of "how long does it take to drink milk tea"-buy 4 different brands of freshly made tea with different flavors (collectively referred to as "milk tea"), and ask professional institutions to detect the colonies in the milk tea Total number and changes

It is understood that the four milk tea flavors purchased by the Shanghai Consumer Protection Committee are domineering grape jade oil orange, boba milk tea, Oreo cake milk tea and oat milk poplar nectar

The test results show that among the 4 cups of milk tea that have been drunk, the total number of colonies of oat milk and poplar nectar grows the fastest over time

In terms of the absolute value of the total number of colonies, Oreo cake milk tea and Boba milk tea with relatively complex materials have higher values

Shanghai Consumer Protection Committee, also on the "unopened tea time whether longer," the problem was tested

In this test conducted by the Shanghai Consumer Protection Committee, the test time is calculated based on the delivery time of the milk tea, and the storage environment is a regular office environment with a room temperature of 26°C

At the same time, information from authoritative testing institutions shows that Shanghai has very strict supervision over fresh milk tea made and sold

The Shanghai Municipal Consumer Protection Committee reminds that the "please drink within 2 hours" written on the milk tea package is calculated from the time the milk tea is made, not from the delivery time
