Inhibition of Aflatoxin Formation by Some Spices

Abstract

The effects of black pepper, cinnamon, peppermint, cumin, ginger and clove on growth and aflatoxin formation of Aspergillus flavus were studied in rice powdercorn steep (RC) medium. The effects of the first five spices were judged to be inhibition of aflatoxin formation rather than of mycelial growth. Clove completely inhibited both mycelial growth and aflatoxin formation at a concentration above 0.1%. No aflatoxin was produced when cumin and mint levels of 5% and 10% were used. Black pepper and ginger levels of 10% decreased aflatoxin formation by 100%. Higher concentrations of cinnamon, mint, cumin and ginger stimulated mycelial growth.

“…Cumin and marjoram retarded citrinin production (Table 3). These results are in harmony to that obtained by many investigators (Hitokoto et al, 1980; Mabrouk and El-Shayeb, 1980; Mostafa, 1990; Krishnamurthy and Shashikala, 2006). …”

“…Black pepper and cardamom, also completely inhibited sterigmatocystin production, however the growth of A. versicolor did not affect. Inhibition of aflatoxin production of different strains of A. flavus and or A. parasiticus by powdered black and white pepper; Cardamom was also recorded by several authors (Hitokoto et al, 1980; Mabrouk and El-Shayeb, 1980; Madhyastha and Bhat, 1985; Mostafa, 1990). Peppermint, cumin and margoram was not affected sterigmatocystin production.…”

“…Mostafa (1990) examined the inhibitory effects of 24 commercial spices and toxin production of four toxigenic Aspergillus ( A. flavus , A. versicolor ) and Penicillium ( P. citrinum and P. corylophilum ) and found that Chinese cassia, cinnamon, clove and thyme completely inhibited the fungal growth of the tested isolates. Mabrouk and El-Shayeb (1980) reported that cloves as a concentration of 0.1% in a medium of rice powder and corn steep liquor, partially inhibited both mould growth and aflatoxin production by A. flavus and completely inhibited mould growth at concentrations of 0.5% or higher. Atanda et al (2007) shows that aflatoxins can be completely inhibited in culture medium with sweet basil leaves and there is the possibility of its being used to protect sorghum against Aspergillus contamination.…”

Plant secondary metabolites as source of postharvest disease management: An overview

“…Syzygium aromaticum (cloves) have been found to be particularly effective, often completely inhibiting both fungal growth and toxin production (Hitokoto et al, 1980;Mabrouk and El-Shayeb, 1980). Many commercially available spices and herbs, turmeric (Curcuma spp), basil (Ocimum basilicum L.), marjoram (Marjorana hortensis Moench.…”
