Answer 2

Food preservation is the process of treating and handling food in order to prevent or slow food decomposition, quality loss, edibility loss, or nutritional value loss, and hence allow for longer food storage.

Explanation:

• There are a variety of food preservation strategies that can be employed to prevent, delay, or otherwise reduce food spoiling.
• Drying is an ancient method of food preservation that decreases water activity to a level that prevents bacterial growth.
• Refrigeration protects food by reducing the growth and reproduction of microorganisms as well as the action of enzymes that cause food to decay.
• Freezing is also one of the most common methods for preserving a wide range of foods, including prepared items that would not require freezing in their raw state.
• Osmosis eliminates moisture from the meat during the salting or curing process. Meat is either salted or sugar-cured, or a combination of the two. Nitrates and nitrites are also commonly used to treat meat, giving it a distinctive pink colour and preventing Clostridium botulinum infection.
