According to the Food and Agriculture Organization of the United Nations (FAO), food loss and food waste refer to the decrease in the mass of food intended for human consumption, throughout all stages of the supply chain.

Food is lost or wasted throughout the supply chain, from initial production down to final household consumption.

How do products such as onion, garlic and corn on the cob manage to keep their interiors moist for such long periods of time?

What features and purposes do the materials of natural packaging have?

Corn on the cob is protected by a series of leaves of porous material. The overlapping and porosity of these sheets allow the corn to stay fresh and retain the most water possible for a longer period of time.

As such, it creates an environment from which it is very difficult for water to escape. The same happens with other vegetables such as pods.
