What is the purpose of Modified Atmospheric Packaging (MAP) in food preservation?

The purpose of Modified Atmospheric Packaging (MAP) is primarily to change the internal atmosphere of the package. This technique involves altering the composition of gases inside the packaging to extend the shelf life of food products. By reducing the oxygen levels and sometimes increasing levels of nitrogen or carbon dioxide, MAP slows down oxidation and the growth of aerobic microorganisms that can spoil food. This helps to maintain the freshness, quality, and safety of the food for a longer period.

The other choices, although they relate to food quality, do not specifically address the primary function of MAP. Enhancing flavor or improving texture may result from proper storage, but they are not direct outcomes of the MAP process itself. Similarly, increasing nutritional value is not a goal of MAP; rather, it is focused more on preserving the existing qualities of food.
