Vietnamese purple potato is not genetically modified. In recent years, people began to pay attention to food nutrition and found that the nutritional value of purple potato is very high. Many new varieties of purple potato with high yield and good quality have been bred by local agricultural research institutions, and there are more purple potatoes on the market, and the price is also higher than the general varieties. Many foods contain anthocyanins. In many purple foods, purple potato not only has high yield and low cost, but also has high anthocyanin content, so it is very popular. Recently, research papers on purple potato have been published, such as "study on Spectral characteristics and Antioxidant activity of anthocyanins in Purple Sweet Potato" published by Modern Food Science and Technology in 2009. studies show that purple sweet potato anthocyanins have strong antioxidant activity.

Fan Zhihong, an associate professor in the Department of Nutrition and Food Safety at the School of Food at China Agricultural University, pointed out, "in fact, natural plants are of various shapes. The same thing, big and small, colorful. People only see a product of one size and one color, just because it is commonly planted by human beings. For example, by crossing various tomato varieties with each other, you can produce tomatoes of different colors, such as crimson, pink, yellow and green, as well as tomatoes of different sizes. These are normal things and have nothing to do with genetically modified genes. Just like people of different nationalities, intermarriage between different races will give birth to hybrids with changes in nose height, mouth shape, eye and hair color, height, and so on. On the contrary, some genetically modified products often look normal, so color or size cannot be used to determine whether they are genetically modified or not. "
