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 2: The particle size distributions of organogel-nanoemulsion prepared under different SORs were analyzed by DLS [size distributions by volume (A) and intensity (B)].

Mentions: During the SOR of optimization process, we chose food-grade Tween 80 as the surfactant, prepared a series of nanoemulsions with different SORs (from 1:8 to 1:3) and same homogenizing pressure of 100 MPa. The results in Figure 2 show that all the samples exhibit similar drop size distributions with a main population around in 100 nm and a mall population in 10 nm. The results indicate that organogel-nanoemulsions prepared with very low concentration of surfactant (SOR 1:8) could achieve narrow and uniform particle size distribution, contributing to a low surfactant additions in food.
