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.

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.
