RESUMO
Aspergillus parasiticus Speare NRRL 2999 growth and aflatoxin production in black and white pepper and the penetration of the fungus in black pepper corn over various incubation periods were studied. Also, the effects of piperine and pepper oil on growth and aflatoxin production were studied. Under laboratory conditions, black and white pepper supported aflatoxin production (62.5 and 44 ppb (ng/g), respectively) over 30 days of incubation. Fungal growth measured in terms of chitin was considerably less in white pepper than in black pepper. A histological study of black pepper corn showed the fungus penetrating up to the inner mesocarp and establishing itself in the middle mesocarp. Piperine and pepper oil were found to inhibit fungal growth and toxin production in a dose-dependent manner. Thus, both black and white pepper could be considered as poor substrates for fungal growth and aflatoxin production.
