“…Another study that includes Pickering emulsions with nanocellulose in the form of nanocrystals (CNC) or nanofibers (CNF) showed zeta potential values of −45.6 ± 3.6 and −49.9 ± 3.9 mV, respectively, and were considered highly electrostatically stable samples [ 21 ]. The CNF emulsions presented significantly higher values than the CNC emulsions (−18.3 ± 1.4 and −11.1 ± 0.9, respectively), characterised as low-dispersion emulsion at the beginning of agglomeration.…”

“…The CNF emulsions presented significantly higher values than the CNC emulsions (−18.3 ± 1.4 and −11.1 ± 0.9, respectively), characterised as low-dispersion emulsion at the beginning of agglomeration. The study explains the difference based on the chemical composition of the essential oils: the ester as a terminal group and a benzene ring may be responsible for the increase in the negative charges [ 21 ].…”

“…Previous studies have investigated different systems to obtain natural preparations based on EOs with antifungal potential in order to select the most suitable EO, carrier, and/or emulsifier for preparing the emulsion. Bacterial cellulose nanocrystals (BCNCs)/fish gelatin (GelA)-based emulsion [ 12 ], chitosan coatings and films loaded with different EOs [ 13 , 14 ], EOs encapsulated in lecithin [ 15 , 16 ], low-density polyethylene [ 17 ], octenyl succinic acid starch [ 18 ], Tween [ 19 ], zeolite, gelatin [ 20 ], and nanocellulose [ 21 ] have been tested. Significant results have been obtained by incorporating EOs into different coarse emulsions (CEs), nanoemulsion (NE), and Pickering emulsion (PE) at different concentrations [ 17 ].…”

This study aimed to investigate the antifungal and antimycotoxicogenic effect of binary and tertiary mixtures of Thymus vulgaris, Origanum sativum, and Coriandrum sativum essential oils (EOs), as well as emulsions based on EO mixtures, on fungi developed on wheat grains destined for the bakery industry. The chemical composition of the EO mixtures, the physical characteristics of the emulsions, and the influence of treatments on the proximate composition of wheat seeds were also studied. The methods used included the microbiological analysis of fungi developed on wheat seeds, the ELISA technique for determining the deoxynivalenol content (DON), gas chromatography coupled with mass spectrometry (GC-MS) to detect the chemical composition of the EOs, Zetasizer to analyse the particle sizes and their electric charge at the surface, and NIR analysis of the proximate composition of wheat. The chemical composition analysis revealed that thymol and o-cymene were the major components in the binary mixture of the EOs with thyme, linalool in the binary mixtures of the EOs with coriander and carvacrol, and o-cymene in the binary mixtures of the EOs with oregano. The results showed that, based on the zeta potential, the tertiary mixture ensured maximum emulsion stability, while the emulsion based on thyme and oregano was the less stable system. Regarding the antifungal and antimycotoxicogenic effect, the results showed that the highest inhibition potential on fungi was observed with the binary mixtures of the EOs based on thyme and oregano, and on deoxynivalenol (DON) when the binary emulsion based on the same EOs was applied to wheat seeds. The proximate composition of wheat seeds contaminated with DON showed an increase in protein content and mineral substances, and there were changes in the colour of the wheat seeds after treatment with the EOs. In conclusion, the results obtained in this study showed the possibility of using binary/tertiary mixtures of EOs and emulsions as healthy and environmentally friendly alternatives in the bakery industry.

“…Cardamom (Elettaria cardamomum; CA) is a perennial, aromatic, herbaceous plant belonging to the Zingiberaceae family, whose use is culinary, domestic, and medicinal. It is a species native to southwest Asia (India, Sri Lanka, Malaysia, and Indonesia), Tanzania, and Guatemala, which has been used since ancient times due to its wide variety of antimicrobial, antifungal, antioxidant, analgesic, anti-inflammatory, and anticancer properties associated with the presence of components such as phenols, tannins, terpenoids, flavonoids, and sterols, among others [7][8][9]. Further, in dentistry, it has been reported that CA possesses antibad breath, anticaries, antiseptic, and antimicrobial properties [10].…”

“…On the other hand, biopolymer-based delivery systems (e.g., nano-composites, microcapsules, emulsions, hydrogels, films, or membranes, among others) have been widely used for the incorporation of bioactive compounds [6,9,20,[25][26][27][28]. Additionally, membranes or biodegradable films have been designed as controlled-release systems (e.g., would dressing) for various applications in the medical area [6,20,27,29,30].…”

In this research, developed linseed mucilage (M)-based films loaded with E. cardamom (MCA), C. officinalis (MCO), and co-loaded with both compounds (MCACO) were evaluated. The incorporation of the active compounds modified the color (redness–greenness, and yellowness); however, the thickness remained constant in all treatments (0.0042–0.0052 mm). In addition, the solubilization time of the films (in artificial saliva) to release the active compounds fluctuates between 9 and 12 min. Furthermore, the incorporation of bioactive compounds increased the total phenolic content and antioxidant activity (DPPH and ABTS, respectively), mainly in MCA (inhibition of 81.99 and 95.80%, respectively) and MCACO (inhibition of 47.15% and 39.73%, respectively). In addition, the incorporation of these compounds also decreased the hardness (39.50%–70.81%), deformation (49.16%–78.30%), and fracturability (39.58%–82.95%). On the other hand, it did not modify the adhesiveness, except in MCO. Moreover, SEM micrographs showed a more homogeneous structure in the MCO films among the films that contained CA in the formulation (heterogeneous structure with the presence of protuberances). Finally, due to the previously reported pharmacological properties of E. cardamomun and C. officinalis, the films developed in this study could have an application as a wound dressing in dentistry.
