How to bake sweet potatoes in the oven

You can put the washed sweet potatoes directly into the oven, or you can wrap the sweet potatoes with tin foil and put them into the oven. Generally, they can be baked at 220 degrees for about an hour. It is recommended to choose slender and uniform sweet potatoes.

Why do sweet potatoes sprout purple?

Because the color of the tender shoots is determined by the pigment cells in the sweet potato epidermis, which is mainly the color of anthocyanins. Anthocyanins gather on the shoots, making the tender shoots of sweet potatoes appear purple. When the sweet potato shoots grow to a certain length, the anthocyanins will gradually decrease and the seedlings will generally turn green.

Sweet potatoes that have just sprouted can still be eaten. At this time, the nutrients and taste of the sweet potatoes have not changed much.

The growth of sweet potato sprouts is related to temperature, oxygen, humidity, etc. It is recommended to store sweet potatoes in a cool and ventilated place.
