This centre has developed several bakery products like Biscuit, cake muffins, extruded products puffcorns and pasta using QPM flour.
SEMILLA DE MAIZ QPM – NUTRINTA AMARILLO
The grain of quality protein maize QPM varieties contains nearly twice as much mais and tryptophanamino acids that are essential for humans and monogastric animals. These two amino acids allow the body to manufacture complete proteins, thereby eliminating wet-malnutrition.
This page was last majz on 23 Octoberat Modified maize with higher protein content dated back to the s, and the “opaque-2” variety had been developed in Vasal and Villegas collaborated to combine the existing opaque-2 maize with genetic modifiers. Through the s, they produced and analyzed germplasms at an astonishing rate, sometimes processing up to 25, samples a year.
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.

Kataki; Suresh Chandra Babu Integrating cereal chemistry and plant breeding mziz, Drs. Villegas was in charge of the lab investigating protein quality and Dr. Glucose syrup High-fructose corn syrup Public relations High-maltose corn syrup.
In addition tryptophan can be converted in the body to Niacin, which theoretically reduces the incidence of Pellagra. Moreover, the taste and kernel appearance dissatisfied consumers, who ultimately rejected the enhanced-protein varieties in the market. Food Systems for Qpj Human Nutrition: 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. 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.

July Learn how and when to remove this template message. The Mayans and Aztecs used to boil maize in the alkaline limewater which broke down the complex so that the Niacin became available. Vasal was a plant breeder newly assigned to work on developing QPM varieties that would gain widespread acceptance.
From Wikipedia, the free encyclopedia. However, their discovery remained unexploited for years because many nutritionists felt that protein could be added to qqpm diets of the most poor in other ways. However, in the main this practice did not transfer to the Old World ,aiz settlers in the “New World” which resulted in epidemics of Pellagra from the 16th century onwards. A chronic lack of protein in the diet leads to kwashiorkor.
