Antifungal activity in lemon and pomegranate peels was considerable against Aspergillus flavus, higher in pomegranate (DIZ 37mm; MIC 135μg/mL). Powdered peels (5, 10, 20% w/w) were mixed in inoculated rice. The inhibitory effect on fungal-growth and production of aflatoxins by A. flavus was investigated at storage conditions - temperature (25, 30°C) and moisture (18%, 21%) for 9months. The maximum total aflatoxins accumulated at 30°C, 21% moisture and at 25°C, 18% moisture were 265.09 and 163.45ng/g, respectively in control. Addition of pomegranate-peels inhibited aflatoxins production to 100% during four month-storage of rice at 25°C and 18% moisture, while lemon-peels showed similar inhibitory effect for 3months at same conditions. However a linear correlation was observed in aflatoxins level with temperature and moisture. Studies showed that both fruit-wastes are potent preventer of aflatoxin production in rice, useful for a safer and longer storage of rice.
柠檬和石榴皮的抗真菌活性对黄曲霉有显著的抑制作用，石榴皮的抑制效果更高（DIZ 37mm；MIC 135μg/mL）。将粉碎的果皮（5%、10%、20%w/w）混入接种的大米中。在 9 个月的贮藏条件下（温度 25、30°C 和水分 18%、21%），研究了其对黄曲霉生长和产生黄曲霉毒素的抑制作用。在 30°C、21%水分和 25°C、18%水分的条件下，对照中总黄曲霉毒素的最大积累量分别为 265.09 和 163.45ng/g。在 25°C 和 18%水分的条件下，石榴皮的添加可在 4 个月的大米贮藏期内抑制黄曲霉毒素的产生，达到 100%，而柠檬皮在相同条件下则可抑制 3 个月。然而，黄曲霉毒素水平与温度和水分呈线性相关。研究表明，这两种水果废料均能有效抑制大米中黄曲霉毒素的产生，有助于大米更安全、更长时间的储存。
