Question

Name some traditional methods of food preservation?

Answer 1

Some traditional methods of food preservation are:

• Removing the water content either by cooking on the fire or Sun drying prevents the growth of bacteria, which spoils the food such as soup powder, milk powder, etc.
• Freezing slows down the decomposition of food by turning moisture into ice, preventing the growth of bacteria. Freezing changes the texture of most vegetables and fruits but not so for meat and fish.
• Pickling involves soaking the food in a salt solution. When it has been pickled for the desired amount of time. Enclosing food items in a sterile container like a glass, plastic or metal can is called canning. The basic principle behind canning is that food is sterilized, usually by heating, and then placed within an air-tight container.
