Yam is a medicinal diet. People often like to use yam to stir-fry or make soup, but many times we will encounter this situation, that is, yam will be covered with black and yellow after peeling and dicing. Many people don't know much about this, and many people think that this is yam deterioration. Then let's introduce how to deal with it.

How to deal with yam blackening

The reason why yam turns black after peeling is that it contains phenols. Yam will turn black when it comes into contact with oxygen in the air, as long as it is not in direct contact with air. You can eat yam when it turns black. Its blackening is mainly due to the color of its own phenolic substances after oxidation, which does not belong to the deterioration range. If it is because yam is usually black after mildew, it is inedible. There is another way to solve this problem. We cut the yam and soak it in cold water with vinegar or lemonade so that it won't turn black. In addition, if you use a metal knife when cutting yam, it will also produce oxidation reaction to make yam black, so if you use a plastic knife to cut yam, it will also avoid yam black.

Seeing the explanation here, people should have a clear understanding of how to deal with the problem of yam blackening. You can soak yam in cold water or vinegar. I hope this introduction is useful to everyone.
