Abstract

In Mexico, corn is the staple food grain; per capita consumption is estimated at 800 g per day and that 70% of the population suffer from    obesity    and   diabetes   type 2. The aim of this study was to determine lipid content and fumoni sin in maize  genetic diversity , to avoid a  potential health risk for high  intake of carbohydrates and toxic substances that interfere with   lipid metabolism  . 25 samples were collected in three states (State of Mexico, Hidalgo and Morelos) at Central Regions in Mexico, (8) landraces were  identified, (10) improved corn hybrids and (7) Bt corn, which were subjected to a  lipid extraction  method Golfisch, AOAC and total fumonisin by ELISA method (Ridascreen Fast Fumoni  sin). Chemical analysis confirmed a significant increase in total lipid content (8.075%) in Bt with respect to the non-Bt maize hybrids (5.07%). The presence of fumonisin levels was detected in 4 mg kg native and improved corn and 0.56 mg kg in Bt maize. In conclusion, the data showed an increase in total lipids in maize, which expressed a recombinant protein ( Cry1Ab) and decreased levels fumonisin, regarding native and improved maize. Fumonisin levels detected may be a risk to consumer health. It is recommended to evaluate the additive effect of excess lipids and fumonisin in the diet of the Mexican population.
