In this study, the effects of dehydrofreezing were investigated to produce high quality citrus frozen foods. The samples were dried for 5 and 22 hours at 50℃ (HD5H and HD22H). Convectional (CV) and immersed freezing (IM) were applied to freezing process. Samples were thawed after freezing at −40℃ and frozen at 5℃. Temperature profiles were measured depending on different water contents in citrus. Partially dehydrated samples showed lower drip loss than non-dehydrated samples. Immersed freezing resulted in lower drip loss than convectional freezing except for partially dehydrated sample. On the whole, hardness was reduced after freezing/thawing. However hardness of HD22H-IM presented as much as those of fresh citrus. Furthermore, HD22H-CV and HD22H-IM exhibited more strength than fresh one. Color values (L<SUP>*</SUP>, a<SUP>*</SUP> and b<SUP>*</SUP>) were reduced after drying. But freezing method had no effect on color values. After freezing and thawing process, the pH and acidity were not changed on non-dehydrated sample. Furthermore, partially dehydrated samples had high free sugars (glucose, fructose and sucrose) compared to non-dehydrated samples. In conclusion, dehydrofreezing can be used effectively to make frozen citrus fruits with improved physical properties and free sugar even after thawing.
