The effects of citrus oils and some spices on growth and aflatoxin production by Aspergillus parasiticus NRRL 2999

The inhibitory effect of various concentrations of mint, sage, bay leaves, thyme, aniseed, red pepper and citrus peel oils on the growth of an aflatoxin-producing strain of Aspergillus parasiticus and its production of aflatoxin was studied. Amongst the herbs used, thyme was found a highly effective antifungal agent. Growth and aflatoxin formation was depressed by orange and lemon oils at a concentration of 1.6% through 10 days incubation. © 1985.
