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.
However, 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.

By the mids, they had produced a QPM germplasm with hard kernel characteristics and good taste similar to the traditional grain and with much higher quality levels of lysine and tryptophan.
For their achievement, they won the World Food Prize.
Retrieved from ” https: Moreover, the taste and kernel appearance dissatisfied consumers, who ultimately rejected the enhanced-protein varieties in the market. Through the s, they produced and analyzed germplasms at an astonishing rate, sometimes processing up to 25, samples a year.

This centre has developed several bakery products like Biscuit, cake muffins, extruded products puffcorns and pasta using QPM flour. These two amino acids allow the body to manufacture complete proteins, thereby eliminating wet-malnutrition. Vasal was a plant breeder newly assigned to work on developing QPM varieties that mziz gain widespread acceptance. From Wikipedia, the free encyclopedia.

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. A chronic lack of protein in jaiz diet leads to kwashiorkor.
Integrating cereal chemistry and plant breeding techniques, Drs. The Mayans and Aztecs used to boil maize qqpm the alkaline limewater which broke down the complex so that the Niacin became available. In Central and South AmericaAfricaand Asiaseveral hundred million people rely on maize as their principal daily food, for weaning babies, and for feeding livestock.
Modified maize with higher protein content dated back to the s, and the “opaque-2” variety had been developed in Glucose syrup High-fructose corn syrup Public relations High-maltose corn syrup.
Vasal and Villegas collaborated to combine the existing opaque-2 maize with genetic modifiers.
