Abstract:
The demand for polyphenols and essential oils (EOs) on the food market is high and grows every year. Its partially the result of the fact that these compounds can be used in formulation of clean label foods, a fast growing food sector. A significant share of polyphenols and EOs are extracted from herbs. The quality of the extracts is determined mainly by the extraction method. Conventional extraction techniques of phytochemicals are time-consuming, operate at high temperatures, and require usage of organic solvents and energy in large quantities. According to the United Nations Sustainability Development Plan, chemical processes should be replaced by green alternatives that would reduce the use of solvents and energy. Ultrasound-Assisted Extraction (UAE), Microwave-Assisted Extraction (MAE) and Cold Plasma-Assisted Extraction (CPAE) meets these criteria. The review shows that each of these techniques seems to be a great alternative for conventional extraction methods ensuring higher yields of bioactive compounds.
摘要:
食品市场对多酚和精油(EO)的需求很高,并且每年都在增长。部分原因是这些化合物可用于清洁标签食品的配方,快速发展的食品行业。大量的多酚和EO是从草药中提取的。提取物的质量主要由提取方法决定。传统的植物化学物质提取技术是耗时的,在高温下运行,并且需要大量使用有机溶剂和能源。根据联合国可持续发展计划,化学过程应该被绿色替代品取代,这将减少溶剂和能源的使用。超声辅助提取(阿联酋),微波辅助提取(MAE)和冷等离子体辅助提取(CPAE)满足这些标准。该综述表明,这些技术中的每一种似乎都是常规提取方法的理想选择,可确保生物活性化合物的产率更高。
