Unfortunately maize corn has two mmaiz 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. 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.

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. Retrieved from ” https: The Mayans and Aztecs used to boil maize mxiz the alkaline limewater which broke down the complex so that the Niacin became available.


Modified maize with higher protein content dated back to the s, and the “opaque-2” variety had been developed in Maz cereal chemistry and plant breeding techniques, Drs.

Quality Protein Maize

Vasal was a plant breeder newly assigned to work on developing QPM varieties that would gain widespread acceptance. In addition tryptophan can be converted in the body to Niacin, which theoretically reduces the incidence of Pellagra. In Central and South AmericaAfricaand Asiaseveral hundred million people rely on maize as their principal daily food, for weaning babies, and for feeding livestock.

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.

Villegas was in charge of the lab investigating protein quality and Dr. Kataki; Suresh Chandra Babu 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.


These two amino acids allow the body to manufacture complete proteins, thereby eliminating wet-malnutrition. List of popcorn brands. July Learn how and when to remove this template message.

Miz page was last edited on 23 Octoberat This centre has developed several bakery products like Biscuit, cake muffins, extruded products puffcorns and pasta using QPM flour. Moreover, the taste and kernel appearance dissatisfied consumers, who ultimately rejected the enhanced-protein varieties in the market.


A chronic lack of protein in the diet leads to kwashiorkor. QPM is a product of conventional plant breeding i.

Glucose syrup High-fructose qm syrup Public relations High-maltose corn syrup. Vasal and Villegas collaborated to combine the existing opaque-2 maize with genetic modifiers.

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.
