Bottom Line: The average droplet size decreased with pressure, and the organogel-nanoemulsion could achieve good stability at low SOR.Positive effects and outstanding antimicrobial activities of organogel-nanoemulsion containing with D-limonene and nisin were confirmed by minimal inhibitory concentrations comparison, growth curves of bacteria, scanning electron microscopy and determination of cell constituents' release.Overall, the research described in the current article show that organogel-nanoemulsion containing with D-limonene and nisin may be an effective antimicrobial system for the production and preservation of food.

ABSTRACT
The aim of this study was to investigate a novel delivery system containing D-limonene and nisin by food organogel-nanoemulsion and study its effect on the antimicrobial activity. Organogel-nanoemulsion containing with D-limonene and nisin or without nisin was prepared by a homogenization method. Factors that may affect the droplet size and stability of organogel-nanoemulsion such as pressure and surfactant to oil ratio (SOR) were studied. The average droplet size decreased with pressure, and the organogel-nanoemulsion could achieve good stability at low SOR. Positive effects and outstanding antimicrobial activities of organogel-nanoemulsion containing with D-limonene and nisin were confirmed by minimal inhibitory concentrations comparison, growth curves of bacteria, scanning electron microscopy and determination of cell constituents' release. Furthermore, the organogel-nanoemulsion applied as food preservative in milk also shown excellent antimicrobial performance. Overall, the research described in the current article show that organogel-nanoemulsion containing with D-limonene and nisin may be an effective antimicrobial system for the production and preservation of food.

Figure 3: Storage stability of organogel-nanoemulsion prepared under different pressures (A) and SORs (B) at 28°C.

Mentions: In our previous study, D-limonene organogel-based nanoemulsion exhibited a good stability: the particle size increased 10 nm at 28°C and 6 nm at 4°C during a storage period of 2 weeks (Zahi et al., 2014). In this study, we got similar and even better results. The results in Figure 3 show that the storage stability of organogel-nanoemulsions prepared with different pressures (Figure 3A) and SORs (Figure 3B). There was only a very slight increase in the average size for all samples stored at 28°C, which confirmed that organogel-nanoemulsion containing D-limonene and nisin has an excellent stability once more. All the samples were stored at 28°C for no fewer than 3 months showed no stratification or phase separation.
