Food Preservation || Dry Preservation || Wet Preservation || Cold Preservation || Class : 8
old preservation, also known as chilled preservation, is also a method of preserving food. This method involves keeping the food at a low temperature to slow down the rate of spoilage to extend its shelf life. There are various ways of cold preservation, including using a refrigerator, a cold storage center, or traditional methods like burying food in soil for later use.

Refrigeration is one of the most common methods of chilled preservation. In this method, the food is kept in a refrigerator or freezer, which lowers the temperature and slows down the rate of spoilage. Fruits like oranges and tomatoes, as well as vegetables like potatoes, can be stored in a refrigerator to extend their shelf life in houses. Dairy products like milk, cheese, yogurt as well as raw meat, fish, eggs, seafood and poultry can be preserved by refrigeration. This can slow down the growth of bacteria and reduce the risk of food borne illness. Leftovers and other cooked food items can also be refrigerated to prevent spoilage and extend their shelf life.

Cold storage centers are another option for chilled preservation. These centers are designed to provide a controlled environment that maintains a specific temperature and humidity level to preserve the food. In these centers, the food is stored in large refrigerated rooms or containers, and the temperature and humidity levels are constantl
hilled preservation, such as burying food in soil, are still used in some parts of Nepal. This method involves digging a pit in the ground and lining it with straw or leaves. The food is then placed in the pit, covered with more straw or leaves, and then covered with soil. This method creates a cool, dark environment that helps to preserve the food by slowing down the rate of spoilage. By this method, potatoes, ginger, turmeric, etc, can be preserved for later use without spoilage. Overall, chilled preservation is a useful method for preserving food, particularly fruits, vegetables and other fresh items. By keeping the food at a low temperature, the rate of spoilage by microorganism can be significantly reduced, which can extend the shelf life of the food and reduce waste.
