Osmotic dehydration (OD) is a sustainable alternative, offering reduced energy consumption compared to traditional drying approaches. This study investigates the role of OD in stabilizing bioactive compounds in lemon peel, fostering sustainable citrus by-product applications. Employing Response Surface Methodology (RSM) framework, pivotal variables-temperature (30-60 °C), exposure time (60-180 min), and sucrose concentration (50-70°Brix)-were optimized to enhance water loss (WL) and solid gain (SG) while safeguarding bioactive retention. The optimal conditions (58.92 °C, 70°Brix, 159 min) yielded a WL of 3.4 g/g, SG of 1.5 g/g, and high sensory acceptability. The OD treated lemon peel powder exhibited substantial retention of bioactive compounds, including ascorbic acid (4.1 mg/g) and total phenols (2.3 mg gallic acid/g), surpassing untreated controls. This enhanced bioactive profile underscores its potential as a sustainable and functional ingredient in nutraceutical applications.
渗透脱水（OD）是一种可持续的替代方法，与传统干燥方法相比，能耗更低。本研究调查了OD在稳定柠檬皮生物活性化合物方面的作用，促进了柑橘副产品的可持续应用。采用响应面法（RSM）框架，对关键变量——温度（30-60°C）、暴露时间（60-180分钟）和蔗糖浓度（50-70°Brix）进行了优化，以提高水分损失（WL）和固形物增加量（SG），同时确保生物活性物质的保留。最佳条件（58.92°C、70°Brix、159分钟）下，水分损失为3.4克/克，固形物增加量为1.5克/克，感官接受度高。经OD处理的柠檬皮粉表现出生物活性化合物的大量保留，包括抗坏血酸（4.1毫克/克）和总酚（2.3毫克没食子酸/克），超过了未处理的对照组。这种增强的生物活性特征突出了其作为营养保健品应用中可持续和功能性成分的潜力。
