Why is yam black?

After the yam is peeled, it will turn brown in the air, and the color will even deepen after a long time. Some families don't take this phenomenon seriously, but some families are worried about deterioration, poor taste and even health problems.

In fact, the blackening is due to the oxidation reaction of polyphenols after peeling yam, forming brown pigment and melanin.

If you are worried about eating health problems, you can remove the brown place before eating, or you can add salt to the peeled and washed yam and stir it so that the peeled yam will not change color.
