Conclusions
The review highlights the influence of growing conditions and weather on the sensory and bioactive properties of these herbs, emphasizing the importance of cost-effective processing and preparation while maintaining maximum sensory attributes and phytochemicals with the highest bioactivities. The retention of polyphenols, antioxidant properties, and essential oil in these herbs is significantly influenced by drying approaches, conditions, and pre-treatments. The review covers aspects such as pre-treatment or processing, extraction parameters, extraction methods, bioactivities, isolation, and preparation or encapsulation. It also discusses the limitations in existing research and suggests directions for future research, including the need for identification, isolation, and purification of individual bioactive compounds using sophisticated approaches.
