Is fruit corn genetically modified? How should I eat it? What are the nutritional values?

Recently, fruit supermarkets and large stores are selling fruit corn, and the price is several times higher than ordinary corn. For a time, there are different opinions, so is fruit corn really genetically modified? How should I eat it? What are the nutritional values?

Is fruit corn genetically modified?

Fruit corn is cultivated by hybrid technology, which is completely different from transgenic varieties. Fruit sweet corn is a type of corn that is different from other corn due to the existence of one or more genes. The flavor of sweet corn is mostly determined by sweetness, which is affected by the amount of sugar and starch in the endosperm. This is inseparable from the role of some mutants. Most of the mutants could increase the content of soluble sugar and decrease the content of starch in endosperm. The effect of a sugar-containing mutant gene can increase the content of water-soluble polysaccharides and decrease the content of starch. This particular mutant alone is of economic importance.

What is the difference between fruit corn and sweet corn?

Fruit corn is a kind of super sweet corn suitable for eating raw. It has thin skin, juicy, crisp and sweet at the green stick stage. It can be eaten directly, and it is especially sweet and crisp when eaten raw and cooked, just like fruit, so it is called "fruit corn". There are many varieties of fruit corn, all of which have very high nutritional value.

Sweet corn is one of the main vegetables in Europe, America, South Korea, Japan and other developed countries. Because of its rich nutrition, sweet, fresh, crisp and tender characteristics, it is favored by consumers from all walks of life.

Sweet corn in production can be divided into three categories: ordinary corn, super sweet corn and enhanced sweet corn. Super sweet corn is widely planted because of its high sugar content and long harvest time. China is the world origin center of waxy corn and has a long history of cultivation. Waxy corn is rich in nutrition and high edible value, so it is widely used as a nutritious food for health care in the world today.

Sweet corn is also cultivated in China. The plant is shorter and the tillering ability is stronger. There are flag leaves on the bracts of the ear. The seeds are yellowish or white, the embryos are large, and the seeds at milk stage are tender and rich in water-soluble polysaccharides, vitamin A, vitamin C, fat and protein.

III. Fruit and corn varieties

Fruit corn is divided into common fruit corn, super sweet fruit corn and enhanced sweet fruit corn in terms of sugar content. Super sweet corn is a variety that can be eaten raw directly. From the color is divided into: yellow, white, two-color (yellow and white), and pure white four kinds.

Fourth, what are the characteristics of cultivation techniques of fruit corn?

Sowing by stages: in order to prevent the trailing of flowers and reduce the quality, fruit corn should be isolated from other types of corn. The picking period of fruit and corn is short and it is difficult to keep fresh. It can be picked and listed in batches by sowing by stages. Generally, the seeds can be sown from the end of March to the beginning of August, and those with heat preservation facilities in early spring can be sown in advance, but sowing between late May and mid-June should be avoided. The flowering and pollination period of corn sown in this period is in the summer drought weather from July to August, which is easy to cause bald tip, grain deficiency or empty stalk.

Sprouting and sowing: it is appropriate to choose sandy loam fields with high soil fertility and sufficient fertilizer and water to cultivate fruit and corn, and fine soil preparation should be done before sowing. Whether it is direct seeding or seedling transplanting, it is best to promote budding and sowing.

Scientific fertilization: the leaves of fruit and corn are spreading, the plant type is loose, and the planting density is 35004000plants per mu. Fertilization should be suitable for the application of base fertilizer, early application of seedling fertilizer, heavy application of panicle fertilizer, combined application of nitrogen, phosphorus and potassium, and advocate the application of organic fertilizer.

Fine management: the growth of fruit corn in seedling stage is weak, and it is vulnerable to insect pests in the later stage, so it is necessary to do a good job in field management in time. After emergence, the seedlings should be checked and filled in time, weeds should be controlled, and corn borer and other pests should be controlled in the middle and later stages. The picking time of fruit corn is about 3 days earlier than that of ordinary sweet corn, and about 20 days after pollination, the best picking time can be grasped in time according to silk color and field taste.
