When the temperature exceeds 40°C, the nutritional value begins to drop. Therefore, the heating method that can retain the nutritive value of milk is to place the container containing milk in warm water at 40° C. and heat the milk through heat transfer.
How to save yogurt is better?
Answer: Due to the need to maintain the activity of this lactic acid bacteria, yogurt should be stored in a low temperature environment, generally 2 °C ~ 6 °C, and the preservation time is usually within 1 month.
