| Abstract: | Three different sizes of cauliflower (Brassica oleracea L. var. botrytis) samples were dried at three
different temperatures and three air velocities. Dried samples were evaluated
for quality attributes, viz. Vitamin C retention, rehydration ratio and
non-enzymatic browning. The samples were heat sealed in high density
polyethylene bags and stored at room temperature for 4 months. The samples were
periodically analyzed for quality attributes on monthly basis. Results
indicated that storage length significantly affected Vitamin C retention and
rehydration ratio in the samples, whereas browning was not affected at all for
the study period. Sensory evaluation resulted in overall acceptability of the
all dried samples, except few dried at 65 °C, at the end of the storage. No sensory damage was observed in the
samples. The storage period and process parameters were optimized to achieve
optimum level of quality attributes. The optimized combination of the
parameters was found to be 55 °C, 60 m/min of drying
air velocity, and 5 cm
cauliflower size for 4 months storage. The responses for the combination were:
Vitamin C retention; 49.03%, and rehydration ratio, 76.13 %, respectively with
desirability factor of 0.659.
