背景香茅是一种具有抗氧化和抗菌作用的芳香植物，用于制备药茶和精油生产。此前的研究表明，柠檬草叶提取物中含有对健康有益的酚类化合物。尽管香草精油被广泛用作调味剂，但没有科学证据表明香茅精油在饮料中的使用。因此，本研究的目的是开发柠檬草衍生物(水提取物、冻干提取物和精油)与柠檬汁的混合饮料，以制备混合饮料，评价混合饮料的抗氧化性和理化特性，并确定混合饮料的感官特性和接受度。结果所制得的混合物具有良好的酸度、色泽等理化性质，并含有生物活性物质(酚类和维生素C)和重要的抗氧化性能。由水浸膏或冷冻干燥浸膏与精油混合制成的混合饮料，显示出更高的柠檬香气和味道，更容易被接受。结论柠檬草衍生物与酸橙汁混合可制成具有良好感官享受和潜在保健成分的高品质混合饮料。(三)2018年化学工业学会
BACKGROUND Lemongrass is an aromatic plant with antioxidant and antimicrobial properties, used for the preparation of medicinal tea and for essential oil production. Previous studies have shown that extracts of lemongrass leaves contain phenolic compounds associated with health benefits. Although essential oils have been widely used as flavoring agents, there is no scientific evidence regarding the use of lemongrass essential oils in beverages. Thus, the objectives of the present study were to develop blends with lemongrass derivatives (aqueous extract, lyophilized extract, and essential oil) and lime juice for the preparation of mixed beverages, to evaluate the antioxidant and physicochemical characteristics of blends, and to determine the sensory profile and acceptance of mixed beverages. RESULTS The formulated blends showed favorable physicochemical characteristics such as acidity and color, and they contained bioactive compounds (phenolics and vitamin C) and important antioxidant properties. Mixed beverages prepared from blends containing aqueous extract or lyophilized extract plus essential oil, which showed higher intensity of lemongrass aroma and flavor, were more readily accepted. CONCLUSION This study demonstrates that it is possible to make suitable blends with lemongrass derivatives and lime juice for the preparation of high-quality mixed beverages with sensory pleasantness, and potentially beneficial health components.
