Special Issue Information

Dear Colleagues,

Medicinal and aromatic plants have an indisputable place in human nutrition, health, and daily life. In the past, medicinal and aromatic plants were used for rituals, wound healing, poisoning treatment, and disease removal. Later, plants begun being used for food seasoning due to their extraordinary flavours and fragrances. Today, the possibility of investigating what particular compounds are related to the usability of medicinal and aromatic plants has arisen.

The food industry currently requires simple and efficient solutions which improve the quality and beneficial aspects of food in a natural and safe manner. Therefore, the effective isolation of volatile and non-volatile fractions of medicinal and aromatic plants and their reliable chemical analysis are highly demanded. Modern, sophisticated analytical techniques like chromatography coupled with mass spectrometry allow us to analyse in depth the valuable constituents of plants and determine the possibility of their usage. Thus, you are kindly invited to submit original research, opinion or review articles regarding the isolation and chemical analysis methods of medicinal and aromatic plant constituents followed by the application of obtained isolates for the design of foods with enhanced quality and health benefits.

The drying process is used in the food industry to extend the shelf life of fruits and vegetables without the use of preservatives. As quality, visual, and aroma characteristics are important determinants of consumer interest, they play a key role in the development of new foods. In the present study, vacuum impregnation (VI) was used prior to vacuum drying (VD) and freeze drying (FD) of courgette and broccoli. Organic beet juice was used to produce the novel snacks. The study showed that the use of vacuum impregnation significantly affected the VOCs profile (volatile organic compounds profile), in which the following compounds were found: viz: 2-(E)-hexen-1-ol, 2-(Z)-hexen-1-ol and aceto-phenone. VI caused a decrease in volumetric gel index (VGI), drying shrinkage (S), water activity (AW), decreased color saturation (∆C), and increased dry matter content (DM). All these properties testify to the positive effect of the pretreatment used. The drying methods used had a significant effect on the properties of the dried vegetables. The dries obtained by the FD method showed higher density and water activity, as well as better preserved color (lower ∆E) and higher VOCs, so it is considered that freeze drying is a suitable method for obtaining novel courgette and broccoli snacks.
