Abstract


Aromatic and medicinal plants have attracted the scientific interest of the food industry, biotechnology, pharmaceutical and cosmetics, since they have been used for many purposes as medicinal, flavouring, beverages, fragrances, cosmetics and other industrial uses. There is a lot of research evidence demonstrated that several factors, mainly the type of storage, the drying process and the extraction methods, should be carefully taken into account because they can induce partial losses of the bioactive components like volatile fraction, antioxidant, or phenolic content in some aromatic and medicinal plants. This review paper, aim to present and compare different methods of drying, convection oven drying (CD), drying in a vacuum oven (DVO), freeze-drying (FD), microwave drying (MD), air drying with the sun exposure (SUD) and without it (SHD) and drying at ambient temperature in a dark (DAT), in terms of storage process and quality, phenolic content and antioxidant capacity of some aromatic and medicinal plants.

Keywords


air-drying, aromatic plants, freeze-drying, microwave drying, phenolic content, quality, storage.
