El perfil lipídico de maíces híbridos y nativos de climas tropicales contaminados con aflatoxinas y fumonisinas

Abstract

Corn is a cereal rich in fat, basic on Mexican diet and susceptible to contamination by mycotoxins. The lipid profile of maize is knowing principally in temperate climates but not completely in the new maize genotypes adapted to tropical climates. Exposure to maize contaminated consumption with mycotoxins is associated with chronic degenerative diseases such as liver cancer and fatty acids with insulin resistance. In this study the content of total fat, lipid profile, fumonisins and aflatoxins were analyzed in two genotypes of corn, from the state of Morelos and Mexico City. The hybrid genotypes contaminated with mycotoxins present a total fat content (6.82%) than the native genotypes (5.23%) and palmitic fatty acid (14.28 ppm). Both maize genotypes have contamination with aflatoxins (55.5%) and fumonisins (27.7%). The statistical analysis showed p >0.05 significance of palmitic fatty increase in the main hybrids and natives. The coexistence of aflatoxins and fumonisins in the hybrid markets marketed in tropical climates and their influence on the profile of fatty acids is concluded.
