Viral Baking Soda Trick Fails to Prevent Potato Sprouting, Experts Say

A viral internet trend claims that storing potatoes in a cardboard box sprinkled with baking soda can keep them fresh and sprout-free for months or even a year. The method, popularized by videos including one from an Italian grandmother, suggests that baking soda absorbs moisture and odors, thereby preventing sprouting. However, investigations reveal that while baking soda may help reduce humidity and odors slightly, there is no scientific evidence supporting its effectiveness in stopping potato sprouting.

Experts and plant councils confirm that the key to preserving potatoes lies in maintaining a cool, dark, and well-ventilated environment. Storing potatoes in a breathable container such as a cardboard box, paper bag, or mesh bag, without washing them beforehand, helps prevent moisture buildup that can lead to rot and sprouting. Using airtight plastic containers is discouraged due to increased humidity.

The viral baking soda trick, despite its popularity and optimistic claims, lacks professional endorsement and does not replace the proven storage conditions necessary to keep potatoes fresh. The article emphasizes that proper temperature, darkness, and ventilation are the most reliable factors in extending potato shelf life, not the addition of baking soda.
