Absrtact: In order to expand the development and utilization of radish reel resources, microwave vacuum drying technology was used to dry radish reel. On the basis of single factor experiments, the response surface methodology was used to optimize the microwave vacuum drying process parameters of radish reel, and compared with microwave drying equipment, hot air drying and vacuum drying methods, the effects of microwave vacuum drying on its quality characteristics were studied.
The results showed that the vacuum degree had a significant effect on the drying rate of radish reel, while the thickness of material layer had little effect. The optimum drying parameters were microwave power 438.92 W, vacuum degree 0.09 MPa, loading 151.57 g and material layer thickness 25.49 mm. By comparing the rehydration ratio, chlorophyll content and Vc content of the products under four drying methods, it was found that microwave vacuum drying had the best effect. Microwave vacuum drying is an effective drying technology for radish reel.
