“…The viscosity value of HA1, HA2, HA3, HA4, HA5, HA6, HA7, HA8, and HA9 oil‐in‐water nanoemulsions prepared by adding Aloe vera gel in different percentages of the water phase and hemp seed oil in different ratios of the lipid phase were determined in the range of 2.00–2.30 mPa.s. It is known that the viscosity of the emulsion depends on the structure of the emulsifier used and the viscosity of the oil [31,32] . The increase in the emulsifier and oil ratio used in the present study also caused an increase in the viscosity values of the groups (p<0.05) [33] .…”

The use of nanoemulsions, a nanotechnology technique, is very popular in the food industry to extend the shelf life of foods and preserve their quality. In this study, it was aimed to develop, optimize, and determine the bioactive properties of nanoemulsion containing Aloe vera gel (AVG) and hemp seed oil (HSO) for use in the food industry. Nanoemulsions containing different ratios of AVG (1 %, 2 %, and 3 %) and HSO: Tween 80(T80) (1 : 4; 20, 25, 30 %) were formulated by ultrasonication. Bioactive properties of nanoemulsions were determined by droplet size, polydispersity index (PDI), zeta potential, Transmission electron microscopy (TEM) imaging, Fourier transform infrared spectroscopy (FT‐IR), viscosity, color, whiteness index, turbidity, conductivity, pH, antioxidant (DPPH), and antimicrobial activity analyses. The pH of the nanoemulsions was between 4.74 and 4.88 due to the acidic nature of AVG. PDI was determined in the 0.17 (HA8) range to 0.26 (HA1). According to the FT‐IR spectrum, it was determined that the entire nanoemulsion formulation did not undergo any chemical degradation and their particle sizes (range between 118.9 nm and 170.5 nm) were <200 nm. The small droplet size and PDI values obtained showed that the nanoemulsions had a homogeneous and stable structure in their dispersions. TEM results determined that all nanoemulsions showed a spherical shape, but the structure detected in the HA8 group had a more homogeneous appearance. The antioxidant activity of the nanoemulsions increased depending on the increasing HSO and AVG percentages. Unfortunately, no antibacterial activity of the nanoemulsions was detected against any of the bacterial strains tested. According to the analysis results, it was determined that the best nanoemulsion formulation belonged to the HA8 group containing 3 % Aloe vera gel and 5 % HSO in terms of TEM and PDI analyses.

“…Increased sonication time resulted in a nanoemulsion with a reduced viscosity, which will increase its stability. In the same context, Gorjian et al (2022) studied the viscosity of spearmint essential oil nanoemulsions with various surfactants (Tween 20, Tween 40, and Tween 80). An increase in hydrogen bonding causes a reduction in the molecular distances of emulsion systems and an increase in flow resistance, which means an increase in the viscosity of the system.…”

Antifungal activity of eco-safe nanoemulsions based on Nigella sativa oil against Penicillium verrucosum infecting maize seeds: Biochemical and physiological traits

The main goals of the present investigation were to develop O/W nanoemulsion fungicides based on cold-pressed Nigella sativa (black seed) oil to prevent Penicillium verrucosum infection of maize seeds and to test their antifungal activity against this fungus. Additionally, the effect of these nanoemulsions on plant physiological parameters was also investigated. Two nonionic surfactants namely Tween 20 and Tween 80 were used as emulsifying agents in these formulations. The effect of sonication time and surfactant type on the mean droplet size, polydispersity index (PDI), and zeta potential of the nanoemulsions were determined by dynamic light scattering (DLS). Results indicated that both sonication time and emulsifier type had pronounced effects on the stability of O/W nanoemulsions with a small particle size range (168.6–345.3 nm), acceptable PDI (0.181–0.353), and high zeta potential (−27.24 to –48.82 mV). Tween 20 showed superior stability compared to Tween 80 nanoemulsions. The in vitro results showed that complete inhibition of P. verrucosum-growth was obtained by 10_T80 and 10_T20 nanoemulsions at 100% concentration. All nanoemulsions had increment effects on maize seed germination by 101% in the case of 10_T20 and 10_T80 compared to untreated seeds or the chemical fungicide treatment. Nanoemulsions (10_T20 and 10_T80) were able to stimulate root and shoot length as compared to the fungicide treatment. Seed treatment with 10_T80 nanoemulsion showed the highest AI and protease activity by 75 and 70%, respectively, as compared to the infected control. The produced nanoemulsions might provide an effective protectant coating layer for the stored maize seeds.

“…Jan et al [30] obtained an EE of 91 ± 0.4% for the vitamin D3 nanoemulsion, while the eucalyptus essential oil nanoemulsion reported by Song et al [61] had an EE of 97 ± 1.2%. A curcumin nanoemulsion's highest EE (94 ± 1%) was obtained in a nanoemulsion with 5% oil, 20 min of ultrasound treatment, and 1.5% emulsifier [55]. According to Song et al [61], high-frequency ultrasound provides high values of EE because it supplies enough energy to generate intense disruptive forces and minimize the droplet size of nanoemulsions, which helps to trap the bioactive compound within the encapsulant.…”

“…This is due to the type of emulsifier used. Tween 40 is a non-ionic emulsifier, so it does not present a charge but prevents the aggregation of oil droplets through steric hindrance by generating a barrier with its molecular groups between the oil droplets and the continuous phase [32,55].…”

Every year, millions of foodborne illnesses with thousands of deaths occur worldwide, which is why controlling foodborne pathogens is sought. In this study, nanoemulsions of phytochemicals extracted from Plectranthus hadiensis var. tomentosus (PHT) were obtained, and their antioxidant and antimicrobial capacities were evaluated. PHT extracts were obtained by maceration, ultrasound, and Naviglio methods, and their antimicrobial activity against Staphylococcus aureus, Listeria monocytogenes, Escherichia coli, and Salmonella enterica was determined by the microdilution method. The extract with the highest antimicrobial activity was obtained by Naviglio with a minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of 12.5 and 25 mg/mL, respectively, for all bacterial strains. The nanoemulsion (o/w) made with Tween 40, 5% extract, and 50% ultrasonic amplitude had a globule size of 4.4 nm, a polydispersity index of 0.48, and a surface charge of −0.08 mV and remained stable for 30 days. This nanosystem presented significantly higher antimicrobial and antioxidant activity than the free extract. Thus, the nanoencapsulation of the phytochemicals in the PHT extracts is an alternative to protect and enhance their biological activity against pathogenic microorganisms.
