Abstract

Background: The assessment of the nutritional composition and phytochemical screening of banana pseudostem (PB) and flower (FB) advocate this nonconventional food source for routine consumption, considering its various health benefits.

Objectives: The aim is to assess the proximate nutrient composition, fatty acids, minerals, amino acid profile, and global antioxidant response (GAR) of PB and FB.

Methods: Standard analytical procedures were used to determine the nutritional quality and GAR of PB and FB.

Results: The chemical analysis illustrated that functional profile (water holding capacity, oil holding capacity, swelling power, and solubility), and proximate (ash, moisture, protein, fat, dietary fiber, and carbohydrate) contents were substantially high in FB than PB. With a well-proportionate amino acid profile, PB (0.56) and FB (0.54) comprised of a high ratio of essential to nonessential amino acids than those of FAO/WHO requirement (0.38). The mineral analysis revealed that PB and FB were rich in macro and micro minerals in the order K > Ca > Mg > P > Na and K > Mg > Na > Ca > P, respectively. Linoleic acid was found to be the major component in PB and FB. Besides, total antioxidant activity conducted for PB and FB by GAR method, measuring both bio-accessible and insoluble fractions, revealed that the soluble fraction fared better than the chemical extracts.

Conclusion: The results revealed high nutritional qualities of the byproducts of banana and the low cost of its production promotes their use as a prospective nonconventional food resource with high nutraceutical value.

Summary: AOAC: Association of Analytical CommunitiesFAO/WHO: Food and Agriculture Organization of the United Nations/World health organization Abbreviations Used: Banana flower was more potent than banana pseudostem in terms of its nutritional quality and total antioxidant capacity affirming their usefulness (of both the secondary products) in the pharmaceutical sector as a nutritional supplement due to the health-related properties of dietary fibre and associated bioactive compounds.
