Effect of Menthol Treatment on the Sprouting and Quality of Potato Tuber
Menthol treatment of potato tubers was evaluated for sprouting inhibition and quality preservation. Different concentrations of menthol were tested for their effectiveness in reducing sprouting rates and preserving quality. Dutch potatoes were used to measure glucoside alkaloid content, moisture content, weight loss, respiration intensity and browning. Higher concentrations of menthol effectively inhibited sprouting and preserved quality during storage.

I asked ChatGPT-4o to translate the main points of the paper about menthol’s effects on potato tubers into simple, everyday language suitable for a general audience. This is the answer (below is the full prompt).
Think about when you bought a bag of potatoes and forgot about it for a few weeks. When you finally remembered, you found them sprouting little green shoots. Not only is this sprouting unattractive, but it also indicates that the potatoes are beginning to lose their quality. They can even develop toxins that are harmful to you. Scientists have been trying to find ways to keep potatoes from sprouting, and one interesting method involves the use of the same substance that gives mint its cool, fresh feel.
Researchers conducted a study to see if menthol could keep potatoes from sprouting and maintain their quality. They used Dutch potatoes, which are fairly common, and treated them with varying amounts of menthol. Here’s what they found:
When they used a higher concentration of menthol (0.5 grams of menthol per kilogram of potatoes), it worked wonders in preventing the potatoes from sprouting. Normally, without any treatment, 100% of the potatoes would sprout within 15 days. But with the menthol treatment, only about 4% of the potatoes sprouted. That’s a huge improvement! It seems that menthol can interfere with the parts of the potato responsible for sprouting.
But stopping sprouting is only part of the story. Potatoes also tend to lose quality over time. They can dry out, turn brown, and develop a bad taste. The study found that menthol helps with these problems as well. For example, potatoes treated with menthol stayed more moist than untreated potatoes. This is important because loss of moisture leads to shrinkage and weight loss, which makes the potatoes look less appealing and reduces their value.
Another key aspect the researchers looked at was how menthol affected the levels of certain chemicals in the potatoes, such as glucoside alkaloids. These are natural compounds in potatoes that can become toxic if they build up too much. Normally, when potatoes sprout, these toxins increase significantly. But with the 0.5 g/kg menthol treatment, the levels of these toxins were kept much lower, well within safe limits.
Now you may be wondering about other quality issues such as browning and nutrient loss. The study showed that menthol helped here as well. Potatoes treated with menthol are browned less than untreated potatoes. Browning is a sign that the potato is starting to go bad and affects both its appearance and taste. The menthol treatment kept the potatoes looking fresher.
The menthol-treated potatoes also retained their starch and protein content better. This means they stayed more nutritious and didn’t convert as much of their stored energy into sugar, which can affect taste and texture. In addition, menthol helped reduce the activity of enzymes that cause browning and spoilage, keeping the potatoes in good shape.
Overall, using menthol to treat potatoes can make a big difference in how long they stay fresh and how good they taste. It prevents sprouting, reduces toxin levels, keeps them moist, and maintains their nutritional quality. So the next time you hear about someone using menthol to keep their potatoes fresh, know that there’s solid science behind it! This simple addition could mean fewer wasted potatoes and more delicious meals from your pantry.
