Why do peaches turn black when washed with baking soda?
Washing peaches with baking soda turns black because anthocyanins produced by peach skin react with baking soda, which is normal and edible. Mature peach skin will produce anthocyanins, which are red in acidic environment and blue-black in alkaline environment. Baking soda is alkaline, so peaches will turn black.

Scientific peach washing:

Washing peach wool with baking soda or alkali is more scientific than washing with salt water. Peach peel is rich in pectin, which is easy to decompose under alkaline conditions, making peach soft, making peach peel easier to peel off and eating more convenient. However, the soaking time with baking soda powder or alkaline water should not be too long, which will not affect the taste of pulp, and will also make the fruit discolored, yellow or brown.
