“…It is a very effective method of preservation, particularly due to volume reduction, ease in storage and transportation, cost efficiency, low energy requirements as well as a remarkable extension in storage period. Ranjan et al (2014) suggested that hot water blanching with 0.125% potassium metabisulphite, microwave blanching for 5 minutes and drying at 65 o C was the most optimum treatment for dehydration of cauliflower. On similar lines, Kad et al (2017) studied effect of different pretreatments, drying time and temperature on cauliflower.…”

In this investigation, twenty-five genotypes of cauliflower (Brassica oleracea L. var. botrytis) were selected. The samples were uniformly processed keeping all the processing variables (thermal and drying time) constant and dried to a shelf stable product. The effects on moisture content, ascorbic acid, rehydration ratio, antioxidant capacity and sensory acceptability of the product obtained was investigated initially and at the end of storage period. The initial moisture content in the dried cauliflower samples presented values around 4% which increased to approximately 7% at the end of storage period of 180 days. The initial values for ascorbic acid were found to be in the range of 33.8-41.7 mg/100 g DW, while on the final day of storage lowest (30.4 mg/100 g DW) was observed in entry 2020CAUMVAR4. The difference between genotypes was noted for rehydration ratio. Remarkably, good rehydration ratio >3 was observed in all cauliflower genotypes. However, it was observed that 2018CAUMVAR1 performed the best in terms of rehydration ratio and sensory acceptability. The results are useful to identify cauliflower genotypes more amenable for processing.
