Deep freezing is a preservation method that involves lowering the temperature of food to below -18°C (0°F). This process slows down the growth of bacteria, yeast, and molds, helping to maintain the food's quality, flavor, and nutritional value over time. Common items that are deep-frozen include fruits, vegetables, meats, and prepared meals. The deep freezing process typically involves using a specialized appliance called a deep freezer. This appliance allows for rapid freezing, which helps to form smaller ice crystals within the food. Smaller ice crystals minimize damage to the food's cellular structure, resulting in better texture and taste when thawed.
