SEMILLA DE MAIZ QPM – NUTRINTA AMARILLO
Food Systems for Improved Human Nutrition: Moreover, the taste and kernel appearance dissatisfied consumers, who ultimately rejected the enhanced-protein varieties in the market. Vasal was a plant breeder newly assigned to work on developing QPM varieties that would gain widespread acceptance. Modified maize with higher protein content dated back to the s, and the “opaque-2” variety had been developed in The grain of quality protein maize QPM varieties contains nearly twice as much lysine and tryptophanamino acids that are essential for humans and monogastric animals.
In Central and South AmericaAfricaand Asiaseveral hundred million people rely on maize as their principal daily food, for weaning babies, and for feeding livestock. While its lysine and tryptophan levels were better than those of conventional maize, opaque-2 had lower yields and a soft, chalky kernel, which made it more susceptible to ear rot and insect damage. Villegas was in charge of the lab investigating protein quality and Dr.
A chronic lack of protein in the diet leads to kwashiorkor.

This centre has developed several bakery products like Biscuit, cake muffins, extruded products puffcorns and pasta using QPM flour.
Additionally, pigs fed QPM experience rapid weight gain and are ready for market sooner or can provide an additional quality protein source for small farm families.
Qpmm, their discovery remained unexploited for years because many nutritionists felt that protein could be added to the diets of the most poor in other ways.

Unfortunately maize corn has two significant flaws; it lacks the full range of amino acidsnamely lysine and tryptophanneeded to produce proteinsand has its niacin vitamin B 3 bound in an indigestible complex.

QPM qp a product of conventional plant breeding i. Views Read Edit View history. Through the s, they produced and analyzed germplasms at an astonishing rate, sometimes processing up to 25, samples a year.
In addition tryptophan can be converted in the body to Niacin, which theoretically reduces the incidence of Pellagra. Vasal and Villegas collaborated to combine the existing opaque-2 maize with genetic modifiers.
The Mayans and Aztecs used to boil maize in the alkaline limewater which broke down the complex so that the Niacin became available.
