摘要

摘要市场对干果类健康零食的需求正在迅速增长。为了满足市场对具有更好营养价值和感官特性的水果零食的需求,人们正在探索新的高效干燥技术。在本研究中,远红外辅助折射窗口(FIR)的适用性 + RW)干燥得到香蕉皮,并与RW和热空气(HA)干燥进行了干燥行为、生物活性、风味、微观结构和感官特性的比较。冷杉 + 与HA相比,RW和RW使干燥时间减少了60-75%,能耗减少了38-45%。与HA相比,RW干燥保留了颜色,并保留了更高的酚类物质(19%)、抗坏血酸(22%)和抗氧化能力(16-47%)。在所研究的方法中,HA导致较高的褐变指数和羟甲基糠醛含量。冷杉 + RW和RW干香蕉样品具有最大的风味化合物,更好的整体消费者接受度,并改善了细胞结构,使孔隙变宽。研究表明,RW和FIR + RW具有很好的潜力,可以作为HA的替代干燥技术来生产高质量的果皮。

Far infrared assisted refractance window drying: Influence on drying characteristics and quality of banana leather
Abstract The market demand for fruit-based healthy snacks in dried form is increasing rapidly. Novel and efficient drying techniques are being explored to meet market demand of fruit-based snacks with better nutritive value and sensorial attributes. In this study, suitability of far infrared assisted refractance window (FIR + RW) drying to obtain banana leather was ascertained and drying behavior, bioactives, flavor, microstructure, and sensory attributes were compared with RW and hot air (HA) drying. FIR + RW and RW reduced the drying time by 60–75% and energy consumption by 38–45% as compared to HA. RW drying preserved color and retained higher phenolics (19%), ascorbic acid (22%) and antioxidant capacity (16–47%) compared to HA. Among the studied methods, HA resulted in higher browning index and hydroxymethylfurfural content. FIR + RW and RW dried banana samples had maximum flavor compounds, better overall consumer acceptance and improved cellular structure with widened pores. The study indicated that RW and FIR + RW have good potential to be considered as alternative drying techniques to HA for producing high-quality fruit leather.
