Abstract:
This study was conducted to determine the rehydration properties of dried Cauliflower (Brassica oleracea). The samples were blanched by using 0.25% KMS (Potassium Metabisulphite). After blanching they were dried in tray drier at 50 ^oC, 60 ^oC and 70 ^oC (T₀, T₁, T₂, T₃ respectively). The drying time for Cauliflower required to reduce the moisture content from 92.50% to 5 to 6% was 10 h at 60 ^oC. Quality of dehydrated sample such as rehydration ratio, coefficient rehydration and percent of water were evaluated. The rehydration ratio and co-efficient rehydration in rehydrated sample ranged from 3.84 to 5.50 and 0.305 to 0.449 respectively. The Rehydration characteristics of Cauliflower dried at 60 ^oC (T₂) had showed comparatively better reconstitutions than other treatments. The moisture after rehydration was 76.8 to 82.88. Sensory attributes indicated that drying of Cauliflower at 60 ^oC yield relatively satisfactory dried product. The low temperature (50 ^oC drying produced good color and appearance with overall good acceptability score.
