Sweet corn is genetically modified?
Sweet corn is one of the main vegetables in developed countries such as Europe, America, Korea and Japan. Because of its rich nutrition, sweet, fresh, crisp, tender features and favored by consumers of all classes. The production of sweet corn can be divided into three categories of ordinary corn, super-sweet corn and enhanced sweet corn, super-sweet corn due to the high sugar content, suitable for harvesting a long period of time and get widely planted.
Rumors about sweet corn being genetically modified once flooded the Internet, such as sweet corn is a true genetically modified food! In the United States this kind of corn is only used to feed animals, can not be given to people to eat!
Sweet corn is not a new crop developed in recent years, the earliest documented variety of sweet corn is the 1779 European colonizers from the Iroquois people in the Americas where the collection of Papoon corn, when there is no genetically modified this statement.
Sweet corn is not genetically modified corn
The current sweet corn varieties are not exactly the same as those of a few hundred years ago, but it is not a genetically modified product, but rather on the basis of natural mutations in sweet corn varieties, through traditional breeding techniques to select self-intercrossing lines, the grouping of hybrids to cultivate a new sweet corn varieties.
Of course, sweet corn that has been modified by GM technology to enhance insect and herbicide resistance does exist, but it is not approved for planting in China. It is unlikely that the sweet corn we currently buy in China is genetically modified sweet corn.
Is black corn genetically modified?
Black corn is not genetically modified
Black corn is a special type of corn, there are broadly and narrowly defined, broadly defined black corn, also known as purple corn, refers to the kernels of the color of black, purple, blue and black corn in general, while the narrow sense of the black corn refers to the color of black corn. Black corn is not only unique in color, but also rich in nutrients, sticky and delicious, the most suitable for fresh food. Seeds rich in water-soluble melanin and a variety of essential trace elements, plant protein and a variety of amino acids, nutritional content is significantly higher than other cereal crops.
Because black corn is not common, there is concern that black corn is genetically modified or dyed. The real situation is that is the use of traditional breeding methods, through genetic mutation, natural hybridization (recombination), artificial hybridization and other ways of long-term evolution, selection, is not genetically modified, nor is it caused by artificial dyeing.
Because of the genetic diversity of corn, in the hundreds of years of corn cultivation history, corn also has a variety of different skin color.
