How to distinguish sticky corn from ordinary corn?

The main differences between waxy corn and common corn are as follows:

1, main content

Ordinary corn mainly contains starch.

Sticky corn is an alkaline food, and its main component is sucrose.

2. As far as taste is concerned

Ordinary corn is hard, but chewing slowly is endless.

100% of the starch in the endosperm of sticky corn is amylopectin, which is more digestible than ordinary corn starch, tastes glutinous and fragrant, and can be chewed by the elderly and children.

3. Function.

Ordinary corn is rich in natural vitamin E, which can delay aging, prevent cancer, prevent arteriosclerosis and brain function decline. Moreover, the nutrients contained in the tip of corn embryo can enhance human metabolism, regulate the function of nervous system, make skin smooth and tender, and delay the generation of wrinkles.

Sticky corn not only has the function of ordinary corn, but also contains very rich dietary fiber, so it can lower cholesterol and prevent hypertension and coronary heart disease.

Extended data:

Waxy corn, also known as sticky corn, originated in China. After corn was introduced into China, the hard corn planted in southwest China changed, and the waxy type gradually appeared through artificial selection. The scientific name ZeamaysL.sinensisKulesh means "China species".

Zeng (1987) thought that waxy corn was formed in China before 1760. There are three reasons: waxy corn has been recorded in Three Ji Nong, and China is rich in waxy corn germplasm resources, with more than 500 varieties and materials preserved; Most waxy corn materials in China have isozyme marker bands of waxy corn in China.

At present, four kinds of glutinous rice, purple stem glutinous rice and golden orchid glutinous rice planted in Xishuangbanna, Yunnan Province, all have the original characteristics of waxy corn. Yunnan ethnic minorities generally eat this kind of corn, which has a long history.

G.N. Collins wrote that American missionary J.M.W Farnham brought waxy corn from China to the United States in 1908, and then spread all over the world. Most scholars at home and abroad believe that the origin center of waxy corn is in China. At present, there are some hybrids.

Therefore, the conclusion is that waxy corn belongs to hybrid varieties and has nothing to do with transgenic.
