Abstract

Banana is the largest producing fruit in India. From whole biomass of banana plant, pseudostem contributes 30.81% out of which only 2% are used and the rest are wasted or incinerated. Banana pseudostem is a rich source of both soluble (SDF) & insoluble dietary fiber (IDF). In order to minimize and utilize the wastage, fiber was extracted, analyzed and value added product was developed from pseudostem. By enzymatic gravimetric method, it was found that Banana pseudostem (BPS) after extracting the juice; contain 0.79g insoluble & 0.005g soluble dietary fiber per gram of fiber rich pseudostem powder. Fiber rich pseudostem powder showed hydration properties as Water holding capacity (WHC), Water binding capacity (WBC) & Swelling capacity (SWC), 3.9445 ± 0.155 g/g, 3.762 ± 0.57g/g & 11.51 ± 1.43ml/g respectively. It also had 2.70 ± 0.01ml/g fat binding capacity (FBC) & 72.72% emulsifying capacity (EC). The BPP had glucose predominantly (32.836%) with significant amounts of xylose, galactose, arabinose and mannose. It had substantial amount of arabinose (10.74%), xylose (23.72%), mannose (6.339%), galactose (26.1219%) and glucose (32.836%). The presence of polyphenols (3.875 mg GAE/ g of extract) and flavonoid content (27.7 mg CE/g of extract) provides antioxidant capacity to this fiber material (SDF) as determined by DPPH (EC50 1.054mg/ml) and TRP (1.58 g/100g) assay. The antioxidant capacity of this fiber-rich banana pseudostem powder and its physico-chemical properties render it as ingredients used in the preparation of low-calorie, high-fiber cookies. This fiber rich power was used to prepare cookies at different concentrations (5, 10 15%). Five percent supplementation of banana Pseudostem fiber was found to be suitable for preparation of high fiber cookies with better sensory acceptability. Thus, banana Pseudostem fiber which otherwise is a waste or incinerated can be used as dietary supplement in production of functional foods.
