This detail explains how freezing food and keeping the food for longer is the central idea of the passage.
Why freeze food and keep the food for longer?
Food that has been frozen can be kept for a lot longer, although it will eventually spoil even after being frozen. Bread only lasts three to six months, and meat should be consumed within three months. If you wait much longer, the food will still be safe but start to lose colour, flavour, and texture.
Keep the meal at or below 40 degrees Fahrenheit. Use frozen water bottles, frozen juice boxes, frozen gel packs, or several inches of ice to fill your cooler. Compared to ice cubes, block ice retains longer. Ice blocks can be pre-frozen using clean, empty milk or water containers.
