“…This monoterpene is the major compound in all hydrolates and in the essential oils of the stem and leaf, and the second most abundant compound in the essential oil of inflorescence [35]. In case of C. subhirtella and C. serrulata benzaldehyde was the key component of the essential oils, while benzaldehyde, as well as mandelonitrile was the principal compound of hydrolates [19].…”

Hydrolates, also referred to as hydrosols, floral or distillate waters, as well as aromatic waters, are produced in the same isolation process with essential oils by steam distillation. A small amount of essential oil constituents is dissolved in hydrolates providing specific organoleptic properties and flavor, as well as biological activity which makes them useful as raw material in many industries. Their popularity is still on the rise, especially in aromatherapy. The objective in this review is to analyze the chemical compositions of hydrolates and their corresponding essential oils, as well as biological activity of hydrolates (antimicrobial, antioxidant and antiinflamatory) and potential uses, not only in food industry for flavoring, and preservation of fresh-cut fruits and vegetables, but also as functional (soft) drinks. However, hydrolates can be used in aromatherapy and cosmetics, as well as in organic agriculture and aquaculture.

“…The recovered oil of Y. liliiflora rich in these compounds is highly valued and can find usage in flavor, fragrance and pharmaceutical industries. These results are also consistent with our earlier findings that oils recovered from distillation waste waters are rich in organoleptically important and biologically active compounds …”

BACKGROUND: Aromatic waste water is the main by-product of industrial essential oil distillation. To recover the dissolved essential oil from this distillation waste water, an approach combining column adsorption (CA) and supercritical fluid extraction (SFE) was proposed. Yulania liliiflora was selected as a case study. Activated carbon of mixed porosity was employed and quantitative desorption of the adsorbed oil was achieved using supercritical carbon dioxide (SC-CO 2 ). RESULTS:The optimized condition of CA-SFE was 18 MPa, 308 K, dynamic extraction for 60 min and CO 2 flow rate of 3.6 g min −1 . A recovery of 0.668 ± 0.050 g kg −1 (n = 3) was achieved for the dissolved oil from distillation waste water, significantly higher (P < 0.05) than that obtained by liquid-liquid extraction (LLE) (0.405 ± 0.032 g kg −1 , n = 3). Yulania liliiflora recovered oil was rich in eucalyptol (52. 6-55.2%), -terpineol (15.2-18.1%) and terpinen-4-ol (8.1-8.7%). CONCLUSION:The CA-SFE approach is highly efficient and especially suitable for large-scale application. The recovered essential oil is valued for being rich in organoleptically important and biologically active compounds.

“…The chemical composition of hydrosols of aromatic herbs produced in the same extraction process of EOs is not commonly studied. Their chemical analysis is the subject of only a limited number of publications (34,(59)(60)(61)(62). However, to the best of our knowledge, the chemical composition of T. capitata hydrosol has not been reported until now.…”

Salmonella is recognized as one of the most significant enteric foodborne bacterial pathogens. In recent years, the resistance of pathogens to biocides and other environmental stresses, especially when they are embedded in biofilm structures, has led to the search for and development of novel antimicrobial strategies capable of displaying both high efficiency and safety. In this direction, the aims of the present work were to evaluate the antimicrobial activity of hydrosol of the Mediterranean spice Thymbra capitata against both planktonic and biofilm cells of Salmonella enterica serovar Typhimurium and to compare its action with that of benzalkonium chloride (BC), a commonly used industrial biocide. In order to achieve this, the disinfectant activity following 6-min treatments was comparatively evaluated for both disinfectants by calculating the concentrations needed to achieve the same log reductions against both types of cells. Their bactericidal effect against biofilm cells was also comparatively determined by in situ and real-time visualization of cell inactivation through the use of time-lapse confocal laser scanning microscopy (CLSM). Interestingly, results revealed that hydrosol was almost equally effective against biofilms and planktonic cells, whereas a 200-times-higher concentration of BC was needed to achieve the same effect against biofilm compared to planktonic cells. Similarly, time-lapse CLSM revealed the significant advantage of the hydrosol to easily penetrate within the biofilm structure and quickly kill the cells, despite the three-dimensional (3D) structure of Salmonella biofilm. IMPORTANCEThe results of this paper highlight the significant antimicrobial action of a natural compound, hydrosol of Thymbra capitata, against both planktonic and biofilm cells of a common foodborne pathogen. Hydrosol has numerous advantages as a disinfectant of food-contact surfaces. It is an aqueous solution which can easily be rinsed out from surfaces, it does not have the strong smell of the essential oil (EO) and it is a byproduct of the EO distillation procedure without any industrial application until now. Consequently, hydrosol obviously could be of great value to combat biofilms and thus to improve product safety not only for the food industries but probably also for many other industries which experience biofilm-related problems.
