The official concept of an ecological product does not overlap with the idea of an ecological product at the mental level of the consumer. Most studies, if not all of them, tax this confusion and analyze it as a deviant phenomenon. The starting point for this study was based on this very confusion: If there is so much confusion, it most likely means we are dealing with a symbolic projection at a social level. We found intriguing the idea of trying to understand what exactly are the mechanisms behind the ideological forming of this symbolic projection and their impact upon the decision of purchasing ecological agroalimentary products. The study was based on a nationwide questionnaire conducted in Romania in 2016. The collected data were employed in an anthropological analysis of phenomenological approach to further understand the concept of ecological agroalimentary products as it appears in the mentality of the contemporary Romanian consumer.

The plants used in the experiments are two indigenous medicinal plants belonging to wild and cultivated flora in Romania. Artichocke (Cynara scolymus) and licorice (Glycyrrhiza glabra) were purchased from three local companies trading medicinal plants: Plafar, Vitaplant and Franco Impex. It was evaluated the composition of the extracts in terms of the content of polyphenolic compounds expressed in caffeic acid and flavone compounds content expressed in rutin. Plant extracts were obtained by two different methods of preparation: ultrasonation and maceration with intermittent shaking.

The biggest threat to organisms is represented by fungal attack. Permanently seeking for new solutions to prevent and treatment of diseases caused by fungi, the researchers have turned their attention to antimicrobial peptides. These are produced by a large variety of organisms. The plans are the most important source of peptides having antifungal properties. In the present article is revealed a study of the molecular dynamics of such a peptide, namely the antimicrobial peptide WAMP-1a. Since the conformational structure of the peptide sequence is directly related to its activity, the dynamic parameters were analysed and were identified the amino acid residues that show the largest flexibility.

The advantage lies in the fact that the release of extracts of plants can be controlled and extended by the chemical mediation. The microcapsules were prepared by the process of the interfacial cross–linking. Tropane alkaloids inhibit the proteinases and native/active site shall be secured, by introducing the microcapsules incorporated in the aqueous phase. The paper studied the effects of the influence of pH of the aqueous phase, PMMA, terephthaloyl chloride concentrations, and the rate of stirring on the morphology and size of the microcapsules. The pH was a determining factor in the amount of microcapsules, influencing the encapsulating yield. The size of the microcapsules varied depending on the speed of mixing 50, 100 and 150 rpm respectively. Infrared spectroscopy was performed on the microcapsules prepared under different conditions. Between the spectral changes, the morphology and size of microcapsules may be set a correlation. It was found that the active substances (tropane alkaloids) protected by encapsulation kept constant their activity after microencapsulation.
