Chemical Composition of the Hydrosol and the Essential Oil of Three Different Species of the Pinaceae Family :Picea glauca(Moench) Voss.,Picea mariana(Mill.) B.S.P., andAbies balsamea(L.) Mill.

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.

“…However, the presence of hydrocarbon monoterpenes remained very low in hydrosols due to their poor solubility in water compared to oxygenated monoterpenoids (Rao et al 2002); α-terpineol solubility in water reached 710 mg/L compared to 2.49 mg/L and 4.89 mg/L for α-and β-pinenes (Garneau et al 2012). 6: trans-pinocarveol; 7: borneol; 8: terpinen-4-ol; 9: α-terpineol; and 10: verbenone Interestingly, in black spruce needle hydrosol, α-terpineol was also identified as the main constituent along with borneol, bornyl acetate, and terpinen-4-ol (Garneau et al 2012). The presence of α-terpineol was also reported in the hexane extract of black spruce wood (Pichette et al 1998).…”

“…Shaw described its composition for the first time with bornyl acetate as its main compound (37%), followed by α-pinene (16%), camphene (10%), β-pinene (6.5%), and limonene (6.5%) (Shaw 1950;Guenther 1952). The hydrosol from black spruce needles obtained during hydrodistillation (also named distillation water), has been studied by Garneau et al (2012). Its composition is rich in oxygenated monoterpenes, mainly composed of α-terpineol (14.8%), borneol (13.5%), bornyl acetate (7.8%), and terpinen-4-ol (6.5%).…”

For the first time, the essential oil of Black spruce (Picea mariana) bark residue was obtained using two types of hydrodistillations: steam distillation (SD) and water distillation (WD). Both gave similar yields and compositions as analyzed using gas chromatography and mass spectrometry. The essential oil composition is turpentine-like with the predominance of α-pinene (40.6% SD; 40.5% WD) and β-pinene (33.9% SD; 25.9% WD), followed by hydrocarbon monoterpenes β-phellandrene (4.8% SD; 3.6% WD), 3-carene (4.1% SD; 3.1% WD), and limonene (4.0% SD; 3.7% WD). Hydrosol's composition is rich in oxygenated compounds with α-terpineol (29.3% SD; 33.5% WD), trans-pinocarveol (5.2% SD; 3.7% WD), terpinen-4-ol (5.0% SD; 5.8% WD), verbenone (4.9% SD; 5.4% WD), borneol (4.9% SD; 3.9% WD), and pinocarvone (4.6% SD; 4.3% WD). These black spruce bark essential oils differ in composition from those from needles, which are commercially available and rich in bornyl acetate.

“…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.…”

“…Hydrosols, which are byproducts of the EO distillation procedure (these are situated just under the organic phase at the end of steam distillation), are aqueous solutions and may thus be easily rinsed out from surfaces. In addition, they do not present the strong smell of the EOs, and they did not have any industrial application until now (34). Interestingly, the antimicrobial action of the hydrosol fraction of Satureja thymbra EO has been demonstrated against single-and mixedspecies biofilms composed of technological, spoilage, and pathogenic bacteria (35), but to the best of our knowledge, this is the only report available on the antibiofilm action of hydrosols.…”

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.
