Can i use formalin to preserve potato for ever?

Formalin should not be used to preserve potato or any food item for human consumption. Formalin is a toxic chemical and is commonly used as a preservative in biological specimens for scientific or educational purposes. It is not suitable for preserving food.

Food preservation methods that are safe for consumption include refrigeration, freezing, canning, vacuum sealing, and certain chemical preservatives approved for use in food by regulatory agencies. It's essential to follow proper food handling and preservation guidelines to ensure food safety and quality.

For preserving potato, you can store it in a cool, dark, and dry place, such as a pantry or root cellar. You can also consider storing potatoes in the refrigerator, especially if you live in a warm climate. For long-term preservation, you can freeze potatoes after blanching them to retain their texture and flavor.
