The essential oil Pickering emulsions stabilized by zein and chitosan nanoparticles (ZCPs) were investigated. ZCP stabilized Pickering emulsions encapsulating citral and/or cinnamaldehyde (ZCP-CT, ZCP-CN, ZCP-CTCN) were constructed as an effective antimicrobial system, and the stability and antifungal properties were evaluated. When the ratio of zein to chitosan was 20:1, the emulsion showed good stability within 15 days and good sustained release ability during 9-day storage experiment. All Pickering emulsions could reduce fungal growth and ochratoxin A production. The ZCP-CN inhibited 62.3 ± 0.5 % Aspergillus westerdijkiae and reduced mycotoxin production by 83.8 ± 1.0 % in corn within 15 days. Meanwhile, the ZCP-CTCN inhibited 58.6 ± 1.0 % Aspergillus carbonarius within 8 days, and the inhibition rate of mycotoxin was up to 99.8 ± 0.3 % in grape. The Pickering emulsions could extend the release time of essential oil and improve the anti-fungal efficiency, which provide new ideas for the development of new food mildew inhibitor.
研究了由玉米醇溶蛋白和壳聚糖纳米粒子（ZCPs）稳定的精油 Pickering 乳液。构建了包封柠檬醛和/或肉桂醛的 ZCP 稳定的 Pickering 乳液（ZCP-CT、ZCP-CN、ZCP-CTCN）作为一种有效的抗菌系统，并评估了其稳定性和抗真菌性能。当玉米醇溶蛋白与壳聚糖的比例为 20:1 时，乳液在 15 天内表现出良好的稳定性，在 9 天的储存实验中表现出良好的持续释放能力。所有 Pickering 乳液都能抑制真菌生长和黄曲霉毒素 A 的产生。ZCP-CN 在 15 天内抑制了 62.3±0.5%的威地曲霉，降低了玉米中霉菌毒素的产生 83.8±1.0%。同时，ZCP-CTCN 在 8 天内抑制了 58.6±1.0%的炭黑曲霉，葡萄中霉菌毒素的抑制率高达 99.8±0.3%。Pickering 乳液可以延长精油的释放时间，提高抗真菌效率，为开发新型食品防霉剂提供了新的思路。
