The work aims to study the drying effects of microwave and microwave combined drying technology, in order to provide theoretical reference for the research on postharvest processing and storage of fruits and vegetables in China. The principles, characteristics, research progress and existing problems of microwave drying and microwave combined drying of fruits and vegetables were introduced, and the research on the drying process of fruits and vegetables in China was prospected. Microwave drying technology had a good application prospect in the processing of fruits and vegetables. It could not only achieve the purpose of drying, improved the economic benefits of fruits and vegetables, but also shorten the drying time of fruits and vegetables, reduced energy consumption, and maintained good color and aroma and nutrient content of products. Microwave drying technology plays an extremely important role in the processing of postharvest fruits and vegetables. It is an important technology during postharvest processing of fruits and vegetables and has broad application prospects.
