Will normal black peanuts lose color if soaked in water?

Black peanuts lose color because their dark skin contains anthocyanins.

Anthocyanins are natural pigments that are soluble in water. Therefore, foods containing anthocyanins often lose color when exposed to water, just like cheap and low-quality fading fabrics, which is very unfavorable. Not only does it not give face, it also likes to "change its face", turning red under acidic conditions and blue under alkaline conditions. This "not giving face" and "changing face" can cause it a lot of trouble, making people think that they are buying fake dyed food, which is prohibitive.

In fact, anthocyanins have very good antioxidant capacity. Its antioxidant capacity is 20 times that of vitamin C and 50 times that of vitamin E. It has free radical scavenging, antioxidant, anti-tumor, anti-fatigue and It has functions such as protecting the cardiovascular system and is now a highly regarded antioxidant.

Which of our common foods contain anthocyanins? Strawberries, blueberries, mulberries, grapes, purple sweet potatoes, black beans, black rice, black sesame seeds, etc., and black peanuts all contain anthocyanins.

Anthocyanins will lose color when exposed to water, and will change color when exposed to acid or alkali. Although it is so naughty and causes a lot of trouble when cooking and eating, we still love it and the antioxidant power it brings to our bodies. When I was a child, eating mulberries gave me a black mouth and a black tongue, and I also got a black finger. What a memory, huh?
