Abstract: Different pretreatments, such as scalding, brining, sulfurated or freezing, with microwave respectively on sugar permeability have been studied through tracking down the content variations of VC and sugar in the sugared apples. The results showed that the ways of pretreatment with sulfuring and sugar permeability with low power microwave were optimal. The optimum conditions were as follows: content of sugar 20%, and content of VC 4.11mg/100g, to reach the values of sensory 90 scores.

Key words: pretreatment, sugar permeability with microwave, candied apple
