Deciphering functional characteristics and in-vitro bioactive properties of banana central core stem powder

Banana central core stem powder (CCSP) of seven varieties were studied to elucidate their functional, therapeutic properties and bioactive profiling. 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 mu g/mL and IC50 of 177 mu g/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.

Automated summary

Banana central core stem powder (CCSP) of seven varieties was studied for its functional, therapeutic properties and bioactive profiling. The CCSP showed good flowability and storage-life, as well as high levels of dietary fiber and antioxidant activities. Nendran and Rasthali varieties exhibited higher antioxidant activities and contained more potassium and calcium.
