chilling

Chilling, a method of food preservation, involves storing food at temperatures below 4°C (40°F). This process slows down the growth of microorganisms and retards physical and chemical reactions that cause food spoilage. Refrigeration is commonly used for fresh produce, dairy, eggs, and meats. While refrigeration extends shelf life, it cannot improve the quality of already spoiled food. Modern refrigeration systems often include humidity control to prevent dehydration. Precooling, a rapid cooling process for freshly harvested vegetables, is crucial for maintaining quality by slowing deterioration and reducing water loss. Methods include hydrocooling, contact icing, vacuum cooling, and air cooling. Freezing, another low-temperature preservation technique, involves lowering food temperatures below 0°C (32°F) to convert water into ice, inhibiting microbial growth and preserving nutritional quality for extended periods.1234
