1 Answer

Answer :

(1) at its low temperature, bacteria and moulds are inactive Explanation: Bacteria and moulds find conditions of low pH, moisture, or temperature and high salt or sugar unfavorable for their operation. This is the principle why refrigerators keep food unspoiled for a long time. Bacterial action is severely impaired at temperatures at or below 4 degree Celsius.
