• Food preservation is the process of handling and treating food in such a way so as to control and stop the spoilage while maintaining the flavour, texture, and nutritional value of it.
• Potato chips, fruit jam, and mango pickle are examples of food preservation.
• It also helps in the prevention of growth of microorganisms in food.
