Abstract
Radish leaf protein concentrates (RLPC) were prepared by alkaline extraction and characterized for their antioxidant activity, functional properties, mineral content, in-vitro digestibility and microbial stability. Numerical optimization using the 3-factor Box–Behnken Design of response surface methodology suggested that the optimized extraction was obtained at a pH of 9.46, sample/water ratio of 0.075 and time of extraction 46.89 min resulting in 12.12% yield of RLPC with protein content of 87.64%. Glutelins (41.49%), prolamins (24.96%) and albumins (20.43%) were found to be the three major fractions of the protein concentrate, while globulins (13.00%) contributed as a minor component. The apparent molecular weights of these protein fractions ranged between 14 and 60 kDa. Antioxidant activities (FRAP, ABTS and DPPH) were higher in RLPC as compared to the isolated fractions. Functional properties like water holding capacity, oil holding capacity, emulsifying capacity and emulsion stability of the RLPC were 352, 280, 48.1 and 47.8%, respectively. Ca and Fe were the most abundant major and trace minerals, respectively, present in the RLPC. In-vitro protein digestibility was found to be 93.51% and its microbial load remained in acceptable limits during 42 days of storage under both refrigerated and ambient temperature conditions. Our results indicated that the protein concentrates extracted from radish leaves have considerable antioxidant activity, functional properties, mineral content, digestibility and microbial stability. The results highlight the potential of RLPC for use in functional foods as a safe and cost-effective source of protein.
