Abstract:
This study was aimed at improving nutritional, functional and consumer's safety aspects of dehydrated cabbage powder. White cabbage was processed to cabbage powder after following microwave heating, blanching, alkali and acid washing treatments. The results for nutritional composition of raw and processed cabbage powder (CP) elucidated raw CP to exhibit significantly (p<0.05) higher amounts of protein (12.2%), dietary fiber (25.2%), Na (52 mg/100g), Ca (355 mg/100g), K (286 mg/100g), Fe (14 mg/100g) and Zn (32 mg/100g) as compared to the processed CP. Among different processing techniques deployed to reduce intrinsic and extrinsic toxicants of raw cabbage, microwave treatment resulted in significantly (p<0.05) higher rate of reductions for alkaloids, oxalates, tannins and phytates contents i.e., 77%, 85%, 85%, and 86%, respectively. Likewise, the residual levels of pesticide including imidacloprid, cypermethrin, bifenthrin, chlorpyrifos and deltamethrin were also found to decline at higher rate in microwave processing i.e., 0.98 - 0.12 ppm (87%), 1.22 - 0.23 ppm (80%), 1.03 - 0.15 ppm (84%), 1.97 - 0.43 ppm (77%), and 2.12 - 0.36 ppm (83%), respectively when compared with blanching, alkali and acid washing techniques. Supplementation of CP in unleavened flat bread at a level beyond 5% was observed to significantly (p=0.05) reduce textural and sensory attributes of the baked good. The results suggest microwave heat treatment as a cost-effective technique to reduce natural and environmental load of toxicants in raw cabbage while microwave treated dehydrated cabbage powder supplementation @ 5% in whole wheat flour might serve as a natural mean to ameliorate various nutritional and health disorders.
