About: Waxy corn

An Entity of Type: Abstraction100002137, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

Waxy corn or glutinous corn is a type of field corn characterized by its sticky texture when cooked as a result of larger amounts of amylopectin. The corn was first described from a specimen from China in 1909. As this plant showed many peculiar traits, the American breeders long used it as a genetic marker to tag the existence of hidden genes in other maize breeding programs. In 1922 a researcher found that the endosperm of waxy maize contained only amylopectin and no amylose starch molecule in opposition to normal dent corn varieties that contain both. Until World War II, the main source of starch in the United States was tapioca, but when Japan severed the supply lines of the U.S., they forced processors to turn to waxy maize. Amylopectin or waxy starch is now used mainly in food produc

dbo:abstract
  • Le maïs cireux est un maïs hybride dont l'amidon du grain est entièrement constitué d'amylopectine et qui présente un intérêt particulier pour certaines préparations industrielles. Ce maïs est généralement placé dans le Zea mays Ceratina Group. Il a été décrit comme convariété ou variété de Zea mays (Zea mays var. ceratina Kuleshov) mais n'est généralement plus accepté comme tel Le maïs denté traditionnel contient en moyenne 25% d'amylose et 75% d'amylopectine, et c'est cette dernière qui donne la gluance recherchée par les amidonniers. Or il est très difficile et coûteux de séparer ces deux substances, d'où l'idée d'utiliser le maïs cireux qui produit 100% d'amylopectine. L'amylopectine est utilisée dans les produits alimentaires, textiles, adhésifs ainsi que dans l'industrie du papier et du carton ondulé. Peu après la guerre, des essais montrèrent que l'affourragement à base de maïs cireux permet un engraissement plus rapide que le maïs denté ne le permet. Le maïs cireux connut alors un vif gain d'intérêt. Les généticiens purent démontrer que ce maïs a une déficience dans le métabolisme empêchant la synthèse d'amylose dans l'albumen. Elle est codée par un unique gène (wx). Le maïs cireux donne un rendement de 3,5 % inférieur à ses congénères dentés et se doit d'être planté à au moins deux cents mètres d'un champ de maïs conventionnel si on veut éviter l'hybridation.

Amylopectin or waxy starch is now used mainly in food products, but also in the textile, adhesive, corrugating and paper industry. When feeding trials later on showed that waxy maize could produce more efficient feed gains than normal dent maize, interest in waxy maize suddenly expanded. Geneticists could show that waxy maize has a defect in metabolism precluding the synthesis of amylose in the endosperm. It is coded by a single recessive gene (wx). Waxy maize yield about 3.5% less than their normal dent counterparts and has to be isolated from any nearby normal maize fields by at least 200 meters. (en)
