Description
Summary:[Display omitted] •Central core stem (CCS) is the byproduct after harvesting banana bunches.•Therapeutic properties from CCS of Indian Banana varieties were studied.•CCS is found to be source of functional food ingredient like dietary fiber.•CCS powder of var. Nendran exhibited higher nutraceutical attributes.•GC–MS analysis exhibited higher fatty acids and steroids in CCS powder. Banana central core stem powder (CCSP) of seven varieties were studied to elucidate their functional, therapeutic properties and bioactiveprofiling.CCSP recorded whiteness index in the range of 75.80–80.78.Hauser-ratio (1.12–1.26), Carr-index (10.91–20.75) and aw(0.15–0.22) revealed good flowability and storage-life. A fair amount of insoluble dietary fiber (45.58–51.38 %) was observed in CCSP.Nendran and Rasthali varieties recorded higher antioxidant activities. CCSP registered higher amounts of minerals like potassium (571.84–978.22), calcium (110.65–180.55) and lower sodium (34.10–43.70).Aqueous methanolic extract of Nendran CCSP showed lesser viability of tumour cells (44.32 %) with the concentration of 500 µg/mL and IC50of 177 µg/mL.After seven days of incubation, 5 % Nendran CCSP extract, resulted in higher (78.68 %) reduction of struvite formation.Steroids, terpene and acetate compounds were identified in addition to organic acids and aldehydes.Low sodium, higher dietary fiber and bioactive properties make banana CCSP a cheaper material to contemplate in food-processing and pharmaceutical industries.
