Abstract
This study aims to perform an optimization of process parameter for ohmic blanching of garlic to focus on the drying characteristics of the garlic powder at different temperatures. Comparative analyses on physicochemical and functional properties of differentially blanched garlic powder are carried out. The browning intensity was found to be lesser in garlic with ohmically blanched at 26.66 V/cm for 30 s. Process optimization was carried using different thin layer models, out of which Midilli–Kucuck was found to best fit model (R2 = 0.9954). Rate of drying was significantly higher in ohmically blanched garlic compared to conventional blanching. Obtained garlic powder by differential blanching methods was analyzed for physicochemical and functional attributes specifically; diallyl disulphide content was retained up to 945.8 mg/kg, 928.7 mg/kg and 667.6 mg/kg, respectively.
