There is nothing wrong with the refrigerator. Sterilized milk refrigerated overnight only needs to be heated and boiled, not boiled repeatedly. However, milk stored at room temperature will generally deteriorate overnight, because the best way to preserve milk tea is to put it in the refrigerator without freezing, and when drinking milk tea the next day, you only need to heat it in the microwave oven and boil it with an open flame, so you can drink it. Don't heat it repeatedly.
How long can a little milk tea last, preferably not more than 24 hours?
If it is winter or the temperature is low, it can be sealed and placed in a cool place. If the temperature is slightly higher, the undrinkable milk tea should be kept in the refrigerator to avoid bacterial fermentation and deterioration.
The research shows that the main change is that tea polyphenols are further oxidized and the color is deepened. A cup of clear green tea, especially at high temperature for a long time, will lose its green color and increase its yellow color. This is the yellow-red and reddish-brown oxidation products formed by the oxidation of tea polyphenols in tea, mainly theaflavins, thearubigins, theabrownins and so on. These products are non-toxic and will not cause harm to human body.
The initial fund for opening a store is about 400,000 yuan (including initial fee, deposit, store decoration, all equipment, brand authorization, hardware materials for opening a store, and personnel training), excluding store rent, wages and expenses for recruiting employees in the store, etc.
