A comparative study was done on the health promoting and functional properties of the fibers obtained as by-products from six fruits viz., pomace of carambola (Averrhoa carambola L.) and pineapple (Ananas comosus L. Merr), peels of watermelon (Citrullus lanatus), Burmese grape (Baccurea sapida Muell. Arg) and Khasi mandarin orange (Citrus reticulata Blanco), and blossom of seeded banana (Musa balbisiana, ABB). Highest yield of fiber was obtained from Burmese grape peel (BGPL, 79.94 ± 0.41 g/100 g) and seeded banana blossom (BB 77.18 ± 0.20 g/100 g). The total dietary fiber content (TDF) was highest in fiber fraction derived from pineapple pomace (PNPM, 79.76 ± 0.42 g/100 g) and BGPL (67.27 ± 0.39 g/100 g). All the samples contained insoluble dietary fiber as the major fiber fraction. The fiber samples showed good water holding, oil holding and swelling capacities. The fiber samples exhibited antioxidant activity. All the samples showed good results for glucose adsorption, amylase activity inhibition, glucose diffusion rate and glucose diffusion reduction rate index.
对从六种水果的副产品中获得的纤维的健康促进和功能特性进行了比较研究，这六种水果分别是杨桃（阳桃）和菠萝（凤梨）的果渣、西瓜（西瓜）皮、缅甸葡萄（沙巴卡）和卡西柑桔（柑橘）皮，以及有籽香蕉（野蕉，ABB）的花。纤维产量最高的是缅甸葡萄皮（BGPL，79.94±0.41克/100克）和有籽香蕉花（BB 77.18±0.20克/100克）。膳食纤维总量（TDF）在源自菠萝果渣（PNPM，79.76±0.42克/100克）和BGPL（67.27±0.39克/100克）的纤维部分中最高。所有样品都以不溶性膳食纤维为主要纤维部分。纤维样品表现出良好的持水、持油和膨胀能力。纤维样品具有抗氧化活性。所有样品在葡萄糖吸附、淀粉酶活性抑制、葡萄糖扩散率和葡萄糖扩散降低率指数方面都表现出良好的结果。
