The present study explores the potential antioxidant activity and β-Carotene content of banana peel and banana peel extracted insoluble dietary fibres. Grand Nain cultivar of bananas was selected. Two stages of ripened banana peel powder mainly stage 3 and 4 were compared along with the extracted insoluble dietary fibre for their β-Carotene and antioxidant activity. β-Carotene content in stage 3 banana peel powder and banana peel extracted insoluble dietary fibre powder varied from 42.8 to 29.9 mg/100g and in stage 4 banana peel powder and banana peel extracted insoluble dietary fibre powder varied from 26.8 to 11.8 mg/100g respectively. Antioxidant activity varied from 61.41±1.46% to 61.08±9.46 in stage 3 banana peel powder and banana peel extracted insoluble dietary fibre powder respectively, whereas, in stage 4 banana peel powder and banana peel extracted insoluble dietary fibre powder it varied from 47.46±7.32% to 43.44±8.54% respectively.
It highlights the process of extraction of dietary fibres (Insoluble and soluble) from banana peel biomass.
It highlights the presence of bioactive compound beta-carotene in banana peel and the extracted insoluble dietary fibre.
It shows the variation in the content of beta-carotene and antioxidant activity according to the stages of growth.
It highlights the importance of biomass as a rich source of nutrients and its possible utilization in food products.
