Detailed explanation-1: -Frozen foods should be stored at –18°C (0°F) or lower. If the temperature rises above –18°C, food can become discoloured and lose vitamin content. Lowering the temperature after it has risen does not correct the damage. Frozen food must be kept at −18°C or lower to maintain its quality.
Detailed explanation-2: -The short time limits for home-refrigerated foods will help keep them from spoiling or becoming dangerous to eat. The guidelines for freezer storage are for quality only-frozen foods stored continuously at 0 °F or below can be kept indefinitely. Looking for a specific item?
Detailed explanation-3: -Freezing food means that it is kept at very low temperatures (approximately-18 to-20°C) and has the effect of pausing bacteria. The low temperatures cause a delay in chemical reactions in food, which results in slowing down or causing bacteria to become dormant.
