Banana peel (BP) is the primary by-product generated during banana processing which causes numerous environmental issues. This study examines the physical attributes, proximate analysis, glycoarray profiling, antioxidant abilities, and prebiotic activity of BP. The analysis demonstrated that carbohydrates constituted the primary components of BP and the glycoarray profiling indicated that BP contains multiple pectin and hemicellulose structures. BP also contained phenolic compounds, including (+)-catechin and gallic acid, flavonoid compounds, and antioxidant activities. BP demonstrated prebiotic effects by promoting the proliferation of advantageous gut bacteria while inhibiting the growth of harmful bacteria. The prebiotic index scores demonstrated that BP exhibited a greater capacity to promote the growth of beneficial bacteria in comparison to regular sugar. The study demonstrated the potential of the BP as a valuable source of dietary fibre, bioactive compounds, and prebiotics. These components have beneficial characteristics and can be utilised in the production of food, feed additives, and functional food.
香蕉皮（BP）是香蕉加工过程中产生的主要副产品，会引发诸多环境问题。本研究考察了香蕉皮的物理属性、近似分析、糖阵列分析、抗氧化能力和益生元活性。分析表明，碳水化合物是香蕉皮的主要成分，糖阵列分析表明香蕉皮含有多种果胶和半纤维素结构。香蕉皮还含有酚类化合物，包括（+）-儿茶素和没食子酸、类黄酮化合物以及抗氧化活性。香蕉皮通过促进有益肠道细菌的增殖，同时抑制有害细菌的生长，展现出益生元效应。益生元指数得分表明，与普通糖相比，香蕉皮促进有益细菌生长的能力更强。该研究证明了香蕉皮作为膳食纤维、生物活性化合物和益生元宝贵来源的潜力。这些成分具有有益特性，可用于食品、饲料添加剂和功能性食品的生产。
