Is purple sweet potato genetically modified? Who dares to say that purple potatoes are not genetical

Now there are many varieties of vegetables and fruits on the market, including small tomatoes and cucumbers, large green peppers and strawberries, and purple potatoes in addition to sweet potatoes. In this regard, Fan Zhihong, an associate professor at the Department of Nutrition and Food Safety of the College of Food Science and Technology of China Agricultural University, pointed out that these are not genetically modified products. "In fact, natural plants come in a variety of shapes.

The same thing, big and small, with a variety of colors. People only see products of one size and one color, just because this variety is commonly cultivated by humans. For example, by crossing various tomato varieties with each other, you can breed tomatoes of different colors and sizes, such as crimson, pink, yellow, and green.

These are very normal things, and they are completely unrelated to GMO. It's like people of different nationalities, and when different races intermarry, they will give birth to mixed-race children with changes in the height of the nose bridge, the shape of the mouth, the color of the eyes and hair, and the height of the head. On the contrary, some GMO products tend to look normal, so you can't tell if you are genetically modified by color or size.

This was recommended by the questioner.

Purple sweet potato has been available in our country for a long time, but in recent years, our country has introduced two main purple sweet potato varieties from Japan, and crossed them with domestic varieties to breed a series of purple sweet potato varieties

Purple sweet potato is not a genetically modified food. The main reasons are as follows:

1. The purple color of purple sweet potato is derived from naturally occurring anthocyanins, which are water-soluble natural pigments widely found in plants in nature and are flavonoid compounds. Anthocyanins are found in vacuoles of plant cells and can be converted from chlorophyll. Adverse environments such as low temperatures, hypoxia, and phosphorus deficiency can also promote the formation and accumulation of anthocyanins.

2. Purple sweet potato is a specific variety of sweet potato, Yunnan has this purple sweet potato very early, especially since the 90s of the 20th century, our country has introduced two main purple sweet potato varieties from Japan, and crossed them with domestic varieties to breed a series of purple sweet potato varieties, and these purple sweet potatoes are not genetically modified.

Purple sweet potatoes are not genetically modified.

Due to the purple to dark purple flesh of purple potatoes, it is doubtful whether they are genetically modified foods. In fact, the purple color of purple potatoes is neither genetically modified nor dyed, but derived from naturally occurring anthocyanins, which is also the main difference from sweet potatoes. The nutritional value of anthocyanins is highlighted in the following three identities.

Antioxidant, Japanese scholar Ikuo Suda and others compared the free radical scavenging effect of sweet potatoes with different meat colors, and found that compared with white, yellow, and orange fleshy sweet potatoes, purple potatoes have the strongest ability, and it is the anthocyanins that play an important role.

Regulating the intestinal flora, the anthocyanins in purple potatoes can change the microbial composition of the large intestine and significantly increase the "good bacteria" such as bifidobacteria, lactobacillus and enterococci in the intestine. Eating purple potatoes, which are rich in anthocyanins, is beneficial to the intestinal microbial environment and human health.

Protecting eyesight, when it comes to the protective effect of anthocyanins on eyesight, it is easy to associate it with blueberries. The anthocyanins in purple sweet potato also have a promoting effect on the growth of retinal pigment epithelial cells, and also have a potential effect on protecting vision. Moreover, whether it is from the perspective of ** or anthocyanin content, purple potatoes are more cost-effective.

1. Purple potatoes are not genetically modified food with silver products.

Purple sweet potatoes are non-GMO foods. Purple potatoes have a long history of cultivation in China, and everyone can eat them with confidence.

Purple potato is a native Chinese food, and it has been in this form since the purple potato, but compared with sweet potatoes, the yield of purple potatoes will be less, so the proportion of sweet potatoes on the market will be higher than that of purple potatoes, but this does not mean that purple potatoes are genetically modified food.

2. There is no genetically modified purple sweet potato at present.

The production cost of purple potatoes is low, as long as it is on the right land, it can achieve the scale of mass production, the audience is relatively fixed, and it is impossible to broaden the consumer group, even if it is genetically modified, it will not increase income. Therefore, there is no need for genetically modified purple potatoes. There is currently no genetically modified purple potato.

3. Genetically modified food is a food that is processed into genetically modified food by transferring exogenous genes into a specific organism through genetic engineering, changing some genes inside it to achieve the form it wants to change, and then processing it as raw materials.

4. Purple potatoes contain a large amount of plant anthocyanins, anthocyanins are a super antioxidant, which can remove free radicals in the body after eating, help the body to carry out antioxidants, and have a good beauty effect.

Purple sweet potato is a high-nutritional, low-calorie food, for people in need, eating some purple potatoes is very good for themselves.

Purple potatoes contain a lot of fiber, which can promote the peristalsis of the body and stomach and clear the intestines after eating, so eating purple potatoes regularly can help the body to remove toxins smoothly, and at the same time can also prevent other diseases.

Purple potatoes contain a lot of protein, minerals, vitamins and other nutrients, and regular consumption can promote metabolism and improve the body's immunity.

Purple sweet potatoes are not genetically modified.

Compared with sweet potatoes (red soil sweet potato) and white potatoes (white soil sweet potato), purple sweet potatoes have higher protein content and slightly lower starch content, and at the same time, the content of minerals such as magnesium, iron, and zinc is also better.

At the same time, purple potatoes are also rich in potassium and dietary fiber, and also contain vitamins such as vitamin C, which are about the same as sweet potatoes and white potatoes. Of course, the specific content is related to the variety, some purple potatoes are very dry, and some are very soft and sweet, indicating that there will be some differences in their composition.

Purple sweet potato is a very cost-effective food for supplementing antioxidants. Purple potatoes are rich in anthocyanins, and also contain certain flavonoids and polyphenols, which have certain antioxidant effects.

Now people pay special attention to health and wellness, and they are becoming more and more particular about eating, food should not only be delicious, but also good for the body, purple sweet potato is one of them, it will fade after boiling, some people think it is genetically modified food, otherwise how can it be like this? Why is it purple?

Everyone should know anthocyanins, everyone also planted red-fleshed apples after reading Uncle De's article, which is also rich in anthocyanins, anthocyanins are a class of water-soluble natural pigments, widely found in plants, such as grapes, mulberries and so on. It is the main substance that can make plants show color, and if a large amount of anthocyanins accumulate in sweet potatoes, they will appear purple, which is the purple potato that people see.

Purple sweet potatoes have many functions, such as promoting digestion and absorption, beauty and so on. Purple sweet potato is also a variety introduced by China from abroad, and then it has been hybridized to produce high-quality varieties.

Hybridization refers to the selection of two varieties of sweet potatoes that have certain genetic differences for crossing, and the purple potatoes that are crossed will be better. Transgenic is a plant that has advantages and disadvantages, and in order to make the bred varieties better, the seeds can use genetic engineering to recombine the genes in two different plants.

The biggest difference between them is that hybridization is the genetic selection and reorganization between the same species, while transgenic is the genetic reorganization between different species, such as animals and plants, and the recombination of one plant and another plant is possible.

Purple sweet potato is not genetically modified food, and the reason why purple sweet potato is purple is also its natural nature, which is not poisonous.

China has approved the issuance of a total of 7 kinds of genetically modified crop safety certificates, which are really genetically modified foods: tomato, cotton, petunia, pepper, papaya, corn and rice. China's large-scale commercial production is only insect-resistant cotton and papaya.

Purple sweet potatoes are not genetically modified crops.

Purple potato, also known as black potato, is a root food with very rich nutritional value, containing a lot of protein, starch and pectin. It belongs to an imported food, and its purple color is mainly because it contains a large amount of anthocyanins, which are water-soluble pigments that turn red after encountering acidic substances, so it is not a genetically modified food.

Introduction to purple sweet potato

Purple sweet potato, also known as black potato, is named because the flesh of the potato is purple or even black purple. Purple potatoes are potatoes that feed on tubers and are widely distributed in Guangdong, Guangxi, Hushan, Jiangxi, southern Shaanxi and other places; It is also found in other tropical parts of Asia.

The nutritional composition of purple potatoes is similar to that of ordinary sweet potatoes, and compared with common sweet potatoes and white potatoes, there is not much difference in protein and sugar, the only difference is his color. The purple color of purple potatoes is mainly due to the "anthocyanins" it contains. It contains all the nutrients of sweet potatoes, but is also rich in selenium and anthocyanins.

Anthocyanins are natural antioxidants that have the effect of antioxidant scavenging free radicals. At the same time, anthocyanin is also a water-soluble natural plant pigment, and the purple color of purple potato is ** anthocyanin. Anthocyanins are a large group of substances that are widely found in all crimson, purple or blue vegetables and fruits, such as grapes, blackberries, figs, cherries, eggplants, purple sweet potatoes, blueberries, cranberries, strawberries, mulberries, hawthorn bark, perilla, black (red) rice and other plant tissues.
