Why can't 304 steel be used to store milk?

Milk contains acidic substances, which will react chemically with the stainless steel material of the stainless steel thermos, causing the stainless steel to rust easily after oxidation and causing the heavy metals in the stainless steel to dissolve. In addition, if 304 steel is used to store milk and left for too long, it will easily breed bacteria and cause harm to the human body.

Why can't milk be used to stew bird's nest directly?

Because bird's nest stewing takes a long time and the temperature is also high, and the heating temperature of milk generally cannot exceed 60 degrees. Too high a temperature will not only cause the loss of nutrients in the milk, but also cause the milk to gel, affecting the taste.

Can I still drink the 45-day expired milk?

45 days after the expiration of the bagged milk can not be drunk. Bagged milk is generally made from fresh milk through cooling, raw milk inspection, impurity removal, standardization, homogenization, sterilization (pasteurization or ultra-high temperature sterilization) and other processes. Expired bagged milk will breed bacteria and deteriorate, which will have adverse effects on the body after drinking, so it is not recommended to continue drinking.
