Are genetically modified foods harmful? Some GM food identification knowledge

Some identification knowledge of genetically modified food for reference

Carrots non-genetically modified carrots: the surface is uneven, generally not too straight, from head to tail from thick to thin. And the head is protruding. Genetically modified carrots: the surface is relatively smooth, generally straight, and its tail is sometimes thicker than the middle. And the head is concave inward. Note: carrots are only available in autumn and winter and are generally genetically modified in summer.

Potato non-genetically modified potatoes: the appearance is relatively ugly, the color is generally dark, the surface is potholed, and the skin is irregular. After peeling, the surface will soon become darker and the skin will be white. Genetically modified potatoes: the surface is smooth, the potholes are very shallow, and the color is relatively light. After peeling, there is no obvious change in its surface. Test method: peel first and then see the change before deciding whether to eat or not

Corn genetically modified corn: sweet and crisp, full, graceful, head and grain tail similar

The area where rice has obtained the legal right to grow genetically modified rice in China is Hubei, which should be wary of slender, bright rice. It is easy to be confused with the "long grain incense" in the northeast. Be sure to see the origin clearly when you buy it.

Tomato genetically modified tomato: the color is bright red, the fruit is hard, and it is not easy to crack.

Labels of imported fruits for other identification methods. Generally speaking, the name of the exporting country is printed at the bottom of the label, the middle English letter indicates the name of the fruit, and the top English letter indicates the name of the exporting enterprise. There are usually four Arabic numerals in the middle of each label: the beginning of three characters indicates that the pesticide has been sprayed. The beginning of 4 means genetically modified fruit; the beginning of 5 means hybrid fruit.

(1) the supermarket must pay attention to the purchase of food, first check whether there is a genetically modified label. According to the measures for the Administration of Agricultural genetically modified organisms labeling, genetically modified foods should be labeled. But these marks are afraid of people, as small as only 1.8 mm high, and hide in the most inconspicuous place, careful examination can always be found.

(2) most of the tomatoes and papayas in the supermarket are genetically modified and do not buy them. In terms of safety and quality, individual farmers selling fruit food are much better than supermarkets. In particular, do not be superstitious about foreign supermarkets, where the food is good-looking but not delicious, and there are too many bad and fake ones. 、

(3) the use of genetically modified corn is the earliest, the most widespread and the most, so we should be cautious in buying any corn food, even if it is sold in the supermarket.

(4) the grain color of transgenic wheat is white and transparent, all-horny, and it belongs to the variety of hard, strong gluten and high quality bread wheat. The super excellent transgenic 9506 wheat was introduced in Anhui in 2008, and there are bleach and talcum powder in the flour, so it is more difficult to identify.

(5) China has been secretly developing genetically modified rice for several years, and a few have entered the market, especially beware of long, thin and shiny rice. Northeast rice is not genetically modified at present, you can rest assured that you must look at the outer packaging bags, such as Heilongjiang, Jilin and Liaoning rice industry, northeast rice is japonica rice, short round grain type, which is essentially different from the transgenic rice grown in Hubei and Hunan (such as BT Shanyou 63), and easy to identify. In addition, genetically modified rice is banned in Thailand and there is no problem with its rice.

(6) Millet, oat, buckwheat and sorghum are all small grain crops and there is no time to transgene them. But it won't be clear in the future.
