This morning, I suddenly received a WeChat message about genetically modified food. The article listed 10 types of genetically modified food (includingpurple sweet potatoes) and described the consequences of eating genetically modified food in a very frightening way.The harm of genetically modified food currently has no official definition. Besides purple sweet potatoes, I don't know whether the other 9 types of food are genetically modified. However, I absolutely don't believe that purple sweet potatoes are genetically modified.

About four or five years ago, I brought purple sweet potatoes home for my parents, hoping they would be impressed by this rare food.

My father smiled when he saw it: "We grew this plant for a while. It's called black red yam. Because the yield was too low, no one wanted to grow it."As a writer, I was born in 1972 and grew up in the countryside. I have never seen purple sweet potatoes in my hometown. However, my father said that he grew it for a while, and it was definitely not a lie. He must have grown it before I could remember. Later, because the yield was too low, no one grew it anymore.”

Therefore, purple sweet potatoes were grown in my hometown before 1975. At that time, there was no genetically modified technology. Therefore, purple sweet potatoes could not be genetically modified.

Anyone in my hometown who has grownsweet potatoescan call my hometown to verify what I said, and ask the elderly people over 65, whether they grew black red yams in their time.Of course, the names for purple sweet potatoes vary in different regions. My family members call it black red yam. Its other names include purple red yam, black red yam, and black yam.

To further find strong evidence that purple sweet potatoes are not genetically modified, I consulted "Chinese Sweet Potato Cultivation," which was hosted by the Ministry of Agriculture and the Chinese Academy of Agricultural Sciences in 1984. It was collectively written by dozens of well-known sweet potato experts in China. The third page of the book clearly states: "Sweet potatoes can be divided into purple, orange-red,

apricot-colored,yellow, yellow, and white, etc." This statement fully explains that purple is one of the natural and pure colors of sweet potatoes. It has nothing to do with genetic modification.Currently, there has been no genetic modification breeding work on sweet potato crops in the world. All new sweet potato varieties are produced through traditional hybrid techniques.

Therefore, all the evidence can strongly prove that purple sweet potatoes are not genetically modified!

Additional explanation:

The current purple sweet potatoes can be divided into edible purple sweet potatoes and industrial purple sweet potatoes. Edible purple sweet potatoes are small and have low yields, with better taste and aroma than industrial purple sweet potatoes.

Industrial purple sweet potatoes are larger and have high yields, mainly for extracting food-grade or industrial-grade anthocyanins. These purple sweet potatoes are not delicious. I hope everyone can distinguish between purple sweet potatoes when purchasing.Industrial-grade ube, larger in size, high yield, mainly supplied to enterprises for extraction of edible or industrial-grade anthocyanins. This type of ube is not tasty, so please be careful when buying ube.
