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.
The aim is to assess the proximate nutrient composition, fatty acids, minerals, amino acid profile, and global antioxidant response (GAR) of PB and FB.
Standard analytical procedures were used to determine the nutritional quality and GAR of PB and FB.
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.
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.
AOAC: Association of Analytical CommunitiesFAO/WHO: Food and Agriculture Organization of the United Nations/World health organization 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.
鉴于香蕉假茎（PB）和花朵（FB）具有多种健康益处，对其营养成分进行评估并开展植物化学筛选，提倡将这种非常规食物来源用于日常消费。
旨在评估PB和FB的近似营养成分、脂肪酸、矿物质、氨基酸谱以及整体抗氧化反应（GAR）。
采用标准分析程序来测定PB和FB的营养质量及GAR。
化学分析表明，FB的功能特性（持水能力、持油能力、膨胀力和溶解性）以及近似成分（灰分、水分、蛋白质、脂肪、膳食纤维和碳水化合物）含量均显著高于PB。PB（0.56）和FB（0.54）的氨基酸谱比例恰当，必需氨基酸与非必需氨基酸的比例高于粮农组织/世界卫生组织的要求（0.38）。矿物质分析显示，PB和FB分别富含大量元素和微量元素，顺序分别为钾>钙>镁>磷>钠以及钾>镁>钠>钙>磷。亚油酸是PB和FB中的主要成分。此外，通过GAR方法对PB和FB进行的总抗氧化活性测定，同时测量了生物可利用部分和不溶性部分，结果表明可溶部分比化学提取物表现更好。
结果显示香蕉副产品具有较高的营养品质，且生产成本较低，这促使它们可作为具有高营养保健价值的潜在非常规食物资源加以利用。
AOAC：美国官方分析化学师协会；FAO/WHO：联合国粮食及农业组织/世界卫生组织 香蕉花在营养质量和总抗氧化能力方面比香蕉假茎更具优势，鉴于膳食纤维和相关生物活性化合物的健康相关特性，证实了这两种副产品在制药领域作为营养补充剂的用途。
