Chitosan and other edible coatings to extend shelf life, manage postharvest decay, and reduce loss and waste of fresh fruits and vegetables

Fresh fruits and vegetables contain high percentage of water and continue metabolic activity after being harvested, resulting in ripening, increased sensitivity to decay-causing fungi, and consequent loss and waste. Edible coatings are prepared from naturally occurring renewable sources and can contribute to reducing waste, respecting environment, and consumer health. Chitosan and other edible coatings form a thin layer surrounding fresh produce that acts as a protective agent, extending shelf life, and have the potential to control their ripening process and maintain nutritional properties of the coated product. This review discusses recent research on the application of chitosan and other edible coatings to prevent fungal decay, keep the quality, and reduce fresh product waste.

Automated summary

Fresh fruits and vegetables continue metabolic activity after harvest, leading to ripening, increased susceptibility to decay-causing fungi, and consequent loss and waste. Edible coatings can reduce waste, respect the environment, and benefit consumer health. They act as a protective agent, extending shelf life, and have the potential to control ripening and maintain nutritional properties of fresh produce.
