Abstract

The plant specie, lemon balm (Melissa officinalis L.) is one of the most important species of the Lamiaceae family and its use as a plant extract has been highlighted by the population and the scientific community due to its rich chemical composition and the presence of bioactive compounds with potential antioxidant activity, associated with various health benefits. Research and development of innovative technologies are focused on the identification of these substances, their properties and applications. The present study aimed to select a type of lemon balm extract based on its bioactive compounds and antioxidant potential, obtained from lemon balm microcapsules through the ionic gelation process and evaluate the physicochemical changes and the profile of the volatile compounds. The extract obtained from the fresh plant sample infused at 80 °C showed a higher content of bioactive compounds. Fourier Transform Infrared Spectroscopy analysis revealed similar spectra between the samples. Terpenes and terpenoids were the predominant class of compounds, with compounds such as (E)-citral and caryophyllene being the major compounds in both the fresh lemon balm sample and the microcapsules. The results were satisfactory in the preservation of aroma and volatile compounds through the microencapsulation process by ionic gelation.

离子凝胶法制备香蜂草提取物微胶囊的研究。

柠檬香蜂草（Melissa officinalis L.）是Lamiaceae家族中最重要的物种之一，由于其丰富的化学成分和具有潜在抗氧化活性的生物活性化合物的存在，与各种健康益处相关，因此其作为植物提取物的用途受到了人群和科学界的重视。创新技术的研究和开发主要集中在这些物质的鉴定、性质和应用上。本研究旨在通过离子凝胶法制备柠檬香蜂草微胶囊，根据其生物活性成分和抗氧化能力筛选出一种柠檬香蜂草提取物，并对其理化变化和挥发性成分进行评价。在80°C浸提的新鲜植物样品中提取的提取物显示出较高的生物活性化合物含量。傅里叶变换红外光谱分析显示样品之间的光谱相似。鲜柠檬香蜂草样品和微胶囊中以萜烯和萜类化合物为主，其中(E)-柠檬醛和石竹烯是主要化合物。结果表明，离子凝胶微胶囊化工艺对香精的香气和挥发性成分具有较好的保存效果。
