Origin of potato juice

Potatoes were first discovered by the Incas in Peru between 8,000 BC to 5,000 BC. Spanish conquistadors conquered Peru in 1536 and later took potatoes to Europe with them. For years, Europeans viewed this vegetable as a cause of disease and bad luck. This thought decreased when France was looking for a solid food source for their military and King Louis XVI encouraged its large-scale production. 

The king soon gave funds and acres of land to grow the vegetable. Soon after, people began to change their minds about potatoes when they saw the kind of attention this root vegetable garnered. Later in 1589, Sir Walter Raleigh took potatoes to Ireland. The vegetable slowly spread over other parts of Europe over the next four decades and grew in popularity.

This juice has a wide variety of health benefits. This juice offers a rich blend of nutrients like vitamin C, B vitamins, potassium, and magnesium.

This juice is also rich in phytochemicals and antioxidants that can help control inflammation, prevent disease, and neutralize free radicals

There are also studies that suggest that it can inhibit cancer cells in the colon and liver. However, consuming this drink in excess may be toxic. In extreme cases, this juice may cause diarrhea and bloating. For best results, you should only consume the juice of one large potato per day.

Commercial production

The main constituent (potato) of this juice is the fourth largest food crop globally and the first crop to be grown in space. However, this drink is not produced commercially due to its short shelf life. Most people prefer it raw as its nutrients wear off quickly. 

The general process involved in the production of this juice includes:

  • First, cleaning and cutting the potato.
  • Then, grating or grinding the slices. 
  • Finally, squeezing out the juice.


When making this juice, make sure you wash the potatoes thoroughly. Do not juice sprouted, green, or even spotty potatoes. These potatoes contain solanine, which is a very toxic alkaloid. 

This juice may taste bland, but you can make it more flavorful by blending it with other veggies. It is most beneficial when consumed in less than 20 minutes of making it. However, you can refrigerate it in an airtight glass jar for up to 2 days.
