Is purple sweet potato a genetically modified food?

Purple sweet potatoes are not genetically modified foods, but natural varieties. Purple sweet potatoes are purple because they contain a lot of anthocyanins. The "Chinese Sweet Potato Cultivation" published in 1984 also clearly pointed out that the color of sweet potatoes can be divided into purple, orange, apricot yellow, yellow, white and other colors. It can be seen that the purple color of sweet potatoes is the result of natural cultivation, which is not surprising.

Purple sweet potatoes are actually the same as today's purple corn, black corn, black peanuts, and black wolfberries, and are all naturally bred.

The anthocyanins contained in purple sweet potatoes are soluble in water, so the purple sweet potatoes will lose color when boiled in water. Moreover, they will change color due to different pH values: anthocyanins are purple in a neutral environment, blue-green in an alkaline environment, and purple-red in an acidic environment.

Purple sweet potatoes are rich in anthocyanins, a natural antioxidant that has a free radical scavenging ability that is 20 times that of vitamin C and about 50 times that of vitamin E.

Purple sweet potatoes sprout because the starch and sugar in them are degraded to form nutrients, and the excess nutrients prompt the purple sweet potatoes to differentiate and sprout.
