Waxy corn is a variety of corn. After maize was introduced into China, the hard maize planted in southwest China changed, and waxy maize gradually appeared through artificial selection. It can be seen that sticky corn is the result of gene separation and free combination, so it is not transgenic corn.

Sweet corn is a member of the corn family and has been planted for hundreds of years. In daily life, it is also often called vegetable corn. Although the United States and other countries have genetically modified corn on the market, we don't allow genetically modified sweet corn to be listed in China, so all the sweet corn we buy is non-genetically modified.

The management of genetically modified crops in China is strict, and the promotion and application of genetically modified crops are also strict. Safety evaluation must be carried out and it will take several years. For crops, after the safety evaluation period, it is necessary to examine and approve the varieties.

Matters needing attention in selecting corn

1. Observe appearance: When selecting corn, observe its appearance first. Fresh corn has bright appearance, full seeds and tight bracts. Avoid picking corn with yellow bracts, dry leaves and shriveled grains.

2. Variety selection: The common corn varieties in the market are sweet corn, waxy corn and old corn. Choose the right variety according to personal taste. Sweet corn tastes sweet and crisp, suitable for frying, boiling and other cooking methods; Waxy corn tastes waxy and soft, suitable for steaming, stewing and other cooking methods; Old corn tastes elegant and is suitable for soups and stews.

3. Feel the weight: Pick up the corn with your hands and feel its weight. Fresh corn has heavy weight and tight bracts. If the weight of corn is light, it may be because of water loss and poor taste.

4. Observe the germ: The germ of fresh corn is full and bright green in color. If the germ is black and shriveled, it means the corn is not fresh.

5. Check the pulp: peel off the corn kernels and observe the color and texture of the pulp. Fresh corn syrup has bright color, full texture and luster. If the pulp is dull and the texture is dry, it means that the corn is not fresh.
