What country uses potato flour the most?

It's difficult to definitively say which country uses the most potato flour. There's no publicly available global data specifically tracking potato flour consumption.

However, we can make some educated guesses:

* Countries with a high potato production: Countries like China, Russia, India, and Ukraine are major potato producers. This suggests they likely use a significant amount of potato flour, particularly for local consumption.

* Countries with strong potato-based food traditions: Countries like Germany, Poland, and Lithuania have traditional potato-based dishes and are known for using potato flour in their cuisine.

* Countries with a growing demand for gluten-free products: As gluten-free diets become more popular, countries like the United States, Canada, and Australia see an increasing demand for potato flour as a gluten-free alternative.

Therefore, it's likely that a combination of countries, both major potato producers and those with established potato-based cuisines, utilize the highest amounts of potato flour.

To get a more precise answer, you'd need to research specific consumption data from individual countries, which may not be easily accessible.
