Background technique
Corn (Sweet corn) is one kind of corn, also known as vegetable corn, grass family, Zea.Corn is Europe
One of main vegetables of developed countries such as beauty, South Korea and Japan.Due to it is with nutrition abundant, sweet tea, fresh, crisp, tender characteristic
Deeply by each stratum consumers.Corn is suitble to eat it raw, and green stick stage thin skin, juice is more, matter is crisp and sweet tea, can directly eat it raw, thin
For thin epidermis once stinging brokenly, the juice of faint scent overflows tooth cheek, eat it raw it is ripe eat all special sweet tea, especially crisp, as fruit, therefore
Referred to as " fruit corn ".Fruit corn has a large amount in variety, and all has very high nutritive value.By institute's band recessive gene
Type is different, but be divided into common corn (gene Sh1), super-sweet corn (gene Sh2) and reinforcement corn (gene Su,
Se etc.).Super-sweet corn is planted extensively since sugar content is high, suitable collection period is long.The research of German nutrition and health care association
Show in all staple foods, the nutritive value and health-care effect highest of corn.Corn contains 7 kinds " anatrophics ", they distinguish
It is: calcium, glutathione, vitamin, magnesium, selenium, vitamin E and fatty acid.By the measurement of expert, every hectogram corn can be provided closely
300 milligrams of calcium, almost similar with calcium contained in dairy products, the effect of calcium abundant can play blood pressure lowering.Meanwhile sweet tea
Carrotene contained in corn is converted into vitamin A after being absorbed by the body, and has protective effect on cancer risk;Plant cellulose can accelerate
The discharge of carcinogen and other poisonous substances, lutern, zeaxanthin are conducive to delay eyes aging.In addition, corn also has
Medical care effect can reduce the cholesterol in blood because it contains multivitamin and minerals, contains unsaturated fatty acid
Soften blood vessel and prevention and treatment of coronary heart disease.
