“…The microcapsules containing the EO showed antibacterial activity against Staphylococcus aureus. Further, de Araújo et al [170] performed microencapsulation of sweet orange EO (SOEO) using maltodextrin and gelatin as wall materials in different ratios. The SOEO microcapsules showed antibacterial and antioxidant properties, thereby suggesting microencapsulated CEOs to be of great importance for the food industries.…”

Citrus is a genus belonging to the Rutaceae family and includes important crops like orange, lemons, pummelos, grapefruits, limes, etc. Citrus essential oils (CEOs) consist of some major biologically active compounds like α-/β-pinene, sabinene, β-myrcene, d-limonene, linalool, α-humulene, and α-terpineol belonging to the monoterpenes, monoterpene aldehyde/alcohol, and sesquiterpenes group, respectively. These compounds possess several health beneficial properties like antioxidant, anti-inflammatory, anticancer, etc., in addition to antimicrobial properties, which have immense potential for food applications. Therefore, this review focused on the extraction, purification, and detection methods of CEOs along with their applications for food safety, packaging, and preservation. Further, the concerns of optimum dose and safe limits, their interaction effects with various food matrices and packaging materials, and possible allergic reactions associated with the use of CEOs in food applications were briefly discussed, which needs to be addressed in future research along with efficient, affordable, and “green” extraction methods to ensure CEOs as an ecofriendly, cost-effective, and natural alternative to synthetic chemical preservatives.

“…The volatile compounds belong to several chemical classes such as aldehydes, acids, esters, alcohols, and mainly terpenes, which offer a wide variety of aromatic notes citrus (D-limonene, a major component of orange oil) (Ayala et al, 2017;Xiao, Ma, Niu, Chen, & Yu, 2015) easily oxidizable (Márquez-Gomez, Galicia-García, Márquez-Melendez, Ruiz-Gutiérrez, & Quintero-Ramos, 2017). Therefore, the exposure to adverse environmental conditions may cause volatilization and oxidation of their components, with potential negative impacts on their stability for prolonged storage periods and, consequently, their biological activities (Araújo et al, 2019).…”

Different types of nanoscale components are being tested in the food microencapsulation process, in order to ensure better barrier properties. Thus, this study aimed to evaluate the properties of spray‐dried microparticles containing sweet orange essential oil produced using gum Arabic and maltodextrin as wall materials incorporated with cellulose nanofibrils. Therefore, both cellulose nanofibrils (morphology) and microparticles (load capacity, moisture adsorption isotherms, X‐ray diffractometry, thermogravimetry, and morphology) were characterized. The treatments containing gum Arabic and cellulose nanofibrils showed better results regarding load capacity (17% w/w). The moisture adsorption isotherms showed that replacing gum Arabic by maltodextrin the equilibrium moisture of the microparticles with and without cellulose nanofibrils were decreased. The presence of cellulose nanofibrils increased the thermal stability of the microcapsules, while higher maltodextrin concentration decreased thermal stability. The microparticles had spherical morphology and roughened surface for all treatments. Therefore, cellulose nanofibrils have potential use for application in the spray‐drying process. Practical applications With the development of new technologies, there is great potential for encapsulation of blended polymeric formulations with an innovative approach in presence of nanoscale components. Cellulose nanofibrils offer structural and mechanical properties and act as a thickener and a physical barrier allowing stabilization of the interface oil/water, what contributes to the improvement of the properties of the essential oil microparticles.

“…A short review of in vivo studies of 13 essential oils together with clinical trial data of Salvia officinalis L., S. lavandulifolia Vahl., Melissa officinalis L., Lavandula angustifolia Mill., and Rosmarinus officinalis L. revealed their antioxidant and anti-AChE potential, as well as anti-amyloid and memory-enhancing activities [9]. De Araujo et al [10] point out the antioxidant and antimicrobial activities of Citrus aurantium var. dulcis Hayne essential oil.…”

Cognitive Facilitation and Antioxidant Effects of an Essential Oil Mix on Scopolamine-Induced Amnesia in Rats: Molecular Modeling of In Vitro and In Vivo Approaches

The present study investigated the capability of an essential oil mix (MO: 1% and 3%) in ameliorating amnesia and brain oxidative stress in a rat model of scopolamine (Sco) and tried to explore the underlying mechanism. The MO was administered by inhalation to rats once daily for 21 days, while Sco (0.7 mg/kg) treatment was delivered 30 min before behavioral tests. Donepezil (DP: 5 mg/kg) was used as a positive reference drug. The cognitive-enhancing effects of the MO in the Sco rat model were assessed in the Y-maze, radial arm maze (RAM), and novel object recognition (NOR) tests. As identified by gas chromatography–mass spectrometry (GC–MS), the chemical composition of the MO is comprised by limonene (91.11%), followed by γ-terpinene (2.02%), β-myrcene (1.92%), β-pinene (1.76%), α-pinene (1.01%), sabinene (0.67%), linalool (0.55%), cymene (0.53%), and valencene (0.43%). Molecular interactions of limonene as the major compound in MO with the active site of butyrylcholinesterase (BChE) was explored via molecular docking experiments, and Van der Waals (vdW) contacts were observed between limonene and the active site residues SER198, HIS438, LEU286, VAL288, and PHE329. The brain oxidative status and acetylcholinesterase (AChE) and BChE inhibitory activities were also determined. MO reversed Sco-induced memory deficits and brain oxidative stress, along with cholinesterase inhibitory effects, which is an important mechanism in the anti-amnesia effect. Our present findings suggest that MO ameliorated memory impairment induced by Sco via restoration of the cholinergic system activity and brain antioxidant status.
