Stainless steel vacuum flask can not only keep warm but also keep fresh

Experts choose 4 kinds of drinks: baby milk powder, coffee, orange juice and boiled water. At the same time, he chose a relatively expensive brand thermos cup, and put the boiled boiled water and orange juice into the thermos cup separately; put the baby milk powder brewed with boiling water and The coffee was put into the thermos cup separately, and the experiment results showed that no E. coli/coliform group was detected in the four drinks just filled or the drink that was left in the thermos cup for 6 hours.

Experts pointed out that because heating and boiling is a sterilization process, and the thermos cup has better sealing and heat preservation effects, the four drinks are kept in a high temperature sealed state for a long time. Under these conditions, E. coli/coliforms cannot grow and survive.

It seems that the fresh-keeping function of the stainless steel vacuum flask is still very good, so that everyone does not have to worry about the deterioration of their beverages. As long as the clean stainless steel vacuum flask is used to hold the beverage, it can still play a certain fresh-keeping function. But don't store it for too long, after all, the preservation effect of the vacuum flask is also limited.
