How To Make Flour From Potatoes?

The potatoes only need to be peeled, cooked, and mashed. On the dehydrator, spread them out and let them dry for 12 to 20 hours. They require a lot of time! Crush them in a blender, or for a workout, use a pestle and mortar the old-fashioned way.

What is the purpose of potato flour?

Whole, peeled, and trimmed potatoes are used to make potato flour. Potato flour draws in and holds onto water, resulting in yeast bread that is moist and has a long shelf life. Use potato flour to thicken sauces, gravies, soups, and gluten-free dishes for smoother texture.

How is flour made from potato starch?

Actually, no. The only exception is that potato starch can be used in place of potato flour if you’re using it to keep yeast breads fresh longer. However, the ratio is not 1:1. You should use slightly less potato starch than flour (a potato starch to flour ratio of 3/4) since potato flour is largely starch but not entirely. If not, we’ll discuss some better alternatives to potato starch and flour below.

Can you use ordinary flour in place of potato flour?

You can use potato flour, a gluten-free flour prepared from raw potatoes, in place of other types of flour to give food a potato flavor. In many common baking recipes, it can be used in place of all-purpose or whole wheat flour.

Can you bake bread with potato flour?

If a recipe calls for whole wheat, all-purpose, or bread flour, the proportion of potato flour should be 1:1 by volume. For instance, you shouldn’t substitute more than 1/3 cup potato flour, or slightly more than 3 cups of flour per batch, in a bread and roll recipe.

Without a dehydrator, how can potato flour be made?

It might not be a good idea to get a dehydrator if you don’t frequently use one in your kitchen. Dehydrators are big, bulky devices. I don’t have one since they’re too pricey.

Instead, I dehydrate my meals using a variety of methods. Without this apparatus, potato flour can be made. You can quickly get dried potatoes if you choose one of the following alternate techniques.

Sun Drying

Sun drying is an excellent way to dehydrate potatoes, but it might provide varied effects for different items.

Simply thinly slice the potatoes, place them on a baking sheet, and let them air dry until completely dried. Remember that this procedure requires time.

Potatoes might take up to several days to dry in the sun. To keep insects away from them, you can cover them with a netting.


Complete the standard potato preparation process. After that, place them in the baking tray lined with a sheet. Bake the potatoes for 6 to 8 hours on the lowest heat setting on your oven.

You can boost the heat to 225 degrees Fahrenheit for a period of 2-4 hours if this takes too long for you. Keep the oven door slightly ajar to allow the air to circulate. It is a particularly efficient method of dehydration.


It may take some time to microwave-dehydrate your potatoes. It is, nonetheless, a very successful strategy. Every microwave has a varied level of heat and strength, so it’s also a process of trial and error.

Oven Toaster

In the same manner as you would when using a dehydrator, prepare your potatoes. After that, place them in the toaster oven’s lowest position. For better airflow, keep the door slightly ajar.

Despite their differences, the microwave and toaster oven both do a great job of drying your potatoes. However, the processing times vary. So be sure to periodically inspect your potatoes to see if they have dried out.

For a longer shelf life, store your dehydrated potatoes in canning jars. Any airtight container will work in the absence of jars. Your dehydrated potatoes won’t become infected and soggy if the air is kept outside the container or jar.

Additionally, it will be easier for you to transport during family outings like camping. Dehydration is one of the finest ways to store potatoes, in addition to using them to make potato flour.

What is the name of potato flour?

What Is the Difference Between Potato Starch and Potato Flour? | Home | Food Facts & Kitchen Tips

Jews use potato flour in some kosher recipes because they are not allowed to consume fermented foods throughout the full Passover week. The traditional sweet meal “helmipuuro,” a porridge consisting of milk and potato starch, is a favorite among Finns.

Starch grains are abundant in the potato plant’s root tubers (leucoplasts). These grains come out of the smashed potato cells when they are compressed. This starch is gathered by manufacturers and provided as a dry powder. It is known as potato starch. For easier and more effective potato starch production, new kinds are being created, such as potatoes that exclusively contain the starch molecule amylopectin. Whole peeled potatoes are baked in enormous industrial ovens to produce potato flour. They are then dried and finely ground.

The terms “potato flour” and “potato starch” are mistakenly used by some producers. Since potato starch is frequently referred to and labeled as potato starch flour, confusion results. The terms “potato starch” and “potato starch flour” are interchangeable. However, “potato flour” is a totally distinct substance. The distinctions between potato flour and potato starch will become clearer through comparison. Despite the fact that they both take the shape of a white powder, they differ in a few ways.

Potato Starch Vs. Potato Flour

  • To make potato starch, only the starchy component of the potato is removed and processed.
  • For the procedure, potatoes with a high starch content are chosen.
  • Peeled and cleaned raw potatoes are used. These potatoes’ starch is released with the use of swift technology. After being extracted, the starch is refined to create potato starch, the finished product.
  • The potato processing sector, such as a producer of French fries and potato chips, also produces the starch as a by-product.
  • Whole potatoes must be cooked, dried, and ground to produce potato flour.
  • The potatoes are dried and then processed into a fine powder.
  • To maintain freshness and increase the product’s shelf life, a manufacturer may add preservatives.

The starch is a powder that is white and transparent. Cornstarch-like in appearance and texture.

Wheat flour and potato flour both have a similar feel and texture. Its color might range from off-white to white.

Potato extract or vegetable starch are typically included as ingredients on a potato starch packet’s label.

According to the label on the potato flour packet, the main component of the product is “whole potatoes.”

  • Except when heated, starch doesn’t absorb much water during cooking.
  • The phosphate coupled to the starch makes the solution more viscous and gives it a faintly anionic flavor.
  • Additionally, the phosphate gives it a high swelling power and a low gelatinization temperature (about 140F or 60C).
  • When employed as a thickening, the starch can withstand higher temperatures than cornstarch.
  • The starch has no particular flavor.
  • Its binding power is very strong, though.
  • It might give the dough more volume.
  • It doesn’t cause the solution to become yellow or bubble up.
  • It gives many baked items more moisture. It can give a cake a delicate texture and keep it moist.
  • Compared to starch, flour is both heavier and more flexible.
  • Large volumes of water are absorbed by it.
  • It has a taste of potatoes.
  • It can make baked items lighter and moister when used with wheat flour.
  • It thickens foods and gives frozen desserts a creamier texture.
  • It gives broths, stews, and gravies more body.
  • When used for breading, you obtain a crust that is golden and crunchy. Potato particles typically crisp up more quickly than wheat flour particles do. They also give the completed product a distinctive flavor.
  • The oil and moisture are both retained by the flour. The desiccated particles absorb moisture, which gives the final dish more volume and a better texture.
  • The flour does, however, have a tendency to foam up when the liquid is heated with potato flour. The food’s flavor and consistency may be impacted by this.
  • Towards the end of cooking, the starch is typically used to thicken sauces, soups, and stews. The sauce becomes glossier, silkier, and more translucent as a result.

What flavor does potato flour have?

Potato flour tastes like potatoes, as one might expect, yet it’s not at all unpleasant. You would often add your potato flour to a meal, flour mixture, or cake mix, where other flavors would already overshadow it.

Can potato starch be produced at home?

Have you ever attempted to make a recipe that called for potato starch and been curious about what it is and why it is in it? If so, you are in the proper location. We’ll delve deep into the science of potato starch and explain to you exactly what it is and how it’s produced (even how you could make it yourself).

This piece is part of our series on understanding ingredients. We delve into the science behind the ingredients we use to prepare our food in this series.

What is Potato Starch?

Tubers include potatoes. Every potato has the ability to serve as the seed for a fresh potato plant. You can start a new potato plant by planting one. A potato needs to transport a lot of food, though, in order to develop into a new plant. This food is kept in potatoes as starch. A potato has a lot of carbohydrates because its primary function is to grow into a plant. Potatoes are primarily made of starch, with water accounting for the remaining 20%. So what’s the composition of this starch?

Starch Chemistry

Similar to people, plants use the sugar glucose to fuel their growth and well-being. By means of photosynthesis, they produce this glucose. They produce glucose using sunlight and atmospheric carbon dioxide.

Plants need to store this glucose to prepare for periods when there is less glucose available or, as in the case of potatoes, to prepare for future growth. Many of these glucose molecules were joined together to form a lengthy chain of glucose molecules. These lengthy glucose chains constitute starch, which is a type of polysaccharide. (Note: Humans store extra glucose using a similar principle, except we produce glycogen instead of starch.)

The potato uses starch, which is made up of lengthy chains of glucose molecules, as a source of stored energy.

There are approximately two ways that the glucose molecules can connect to one another. One is by arranging glucose molecules into a protracted, largely linear chain. Except for those at the end, every glucose molecule is connected to two other molecules. This process produces a chemical known as amylose. As an alternative, the glucose molecules may join together in a branch-like pattern. In this instance, a few glucose molecules are linked to three additional glucose molecules, branching off the linear chain. The name of this branched structure is amylopectin.

Amylose and amylopectin are both present in starch in varying amounts, depending on a number of different circumstances. For instance, rice starch differs from potato starch. In addition, different potato varieties will have varying ratios, as well as younger potatoes having a different ratio than older ones. About 20–35% of the starch in potatoes is typically amylose, with the remaining portion being amylopectin.

Starch granules

The majority of the potato is made up of granulated potato starch. Each granule will contain a sizable amount of amylose and amylopectin starch molecules. Since the granules are so tightly packed, their density is higher than that of water (1.5 g/ml), which explains why they serve as storage. This explains why uncooked, raw starch sinks in liquids.

The arrangement of the starch molecules results in a semicrystalline structure. At room temperature, starch is insoluble in water due to its well ordered structure (once you start heating the starch granules that all changes, as we discussed for cooking potatoes and starch thickeners).

Potato granules can range in size from 1 micron, or 1/1000th of a millimeter, up to 100 times that size, or around 110 micron. While larger granules are cuboid or even irregular in shape, smaller ones are spherical or oval in shape.

We won’t go into great detail here, but a starch’s behavior is significantly influenced by the size and form of its granules. Granules of potato starch typically have a big size. Additionally, if you were to examine the granules under a microscope, you would see that they have a very distinct form from, say, grains of wheat or corn. All of this affects how different starches behave and causes subtle variations among them.

Even while starch makes up the majority of the molecules in starch granules, some other molecules might have entered the mix. For instance, there could be some molecules of protein or fat. You may also come across some phosphates in potato starch. Despite only making up a minor fraction of the granules, they have an effect on how they behave. The high water-binding ability, viscosity, transparency, and freeze-thaw resilience of potato starch are all attributed to the phosphates.

How Potato Starch is Made

Manufacturers of potato starch begin by selecting suitable potatoes. You may extract the most potato starch from your incoming potatoes by choosing potatoes with a high starch content, which is preferred by makers of potato starch.

It’s time to separate the starch from the rest of the potato once it has been rinsed and sanitized. Remember that potatoes contain more than 80% water. The potato’s remaining components are mostly constituted of starch, with a small amount of protein and some fibre.

Shred the potatoes

Potatoes are first shred very finely into tiny bits to remove this starch. All of the potato’s cells are disassembled during this phase. These cells contain starch, which is discharged into the water. The starch from the mashed raw potatoes is taken as much as possible by washing them.

Let the starch sediment out

There are no discrete molecules in the starch that exits the cells and enters the water. Instead, there are bigger granules of starch that are hence visible particles. In water, these granules do not dissolve. Instead, if left standing for a long enough period of time, they will sink to the water’s surface. In factories, water and starch are gently guided through extended ‘channels’, giving the starch a chance to settle to the bottom and sediment out (similar to how cocoa particles settle to the bottom of your chocolate milk).

The starch combination still has a lot of water in it at this point, so more drying will be required to make a dry powder. These starch granules are quite big, which makes them largely unsuitable for a quick process like spray drying. Additionally, avoid overheating the starch. After being cooked, starch undergoes a structural change that is permanent. It won’t have the same thickening effect as before as a result. In other words, it no longer serves the same purpose.

In order to make potato starches more useful for their uses, manufacturers have discovered ways to change them. Modified starches are those that have undergone modification (and often labelled as such). There are many other adjustments that might be made. To tailor the starch to their purpose, manufacturers may use enzymes, acid hydrolysis, or one of numerous other conceivable types.

Can you make potato starch at home?

Yes, you can create potato starch at home using a method that is quite similar to one used in factories! In order to break down the potato cells, you need also begin by crushing (or shredding) the potatoes. You must then wait for the starch to settle before rinsing it many times. We’ve included pointers to a useful Wikihow article in the text below.

Remember that handmade potato starch will have a higher degree of variability in quality than commercially produced starch! Depending on the kind of potatoes you used, as well as how much and what kind of granules they have, will determine how your starch will behave. Of course, this isn’t a big deal if your application is quite generic. However, if you’re baking a specific cake recipe, the consistency of potato starch produced in a factory can be advantageous.

Using Potato Starch: What happens when you heat it

You may be wondering what to do with your potato starch now that you have it. The potato starch must first be heated, which is the most crucial stage. Resistant starch makes up the majority of raw, uncooked potato starch. These are those grains of semicrystalline starch. The body is unable to digest this kind of starch. It must be heated or cooked in order to be digestible.

Granules swell and break

When talking about what occurs when you cook a potato, we went into greater detail on what happens when you cook/heat potato starch. Since starch makes up the majority of a potato’s dry matter, its transformation is crucial.

First off, you would often use potato starch when there is water present. The starch won’t dissolve in the water as long as it’s cold, but it will slightly absorb. The starch will begin to absorb more and more water when it is heated, significantly swelling. It will eventually become hot enough after it has absorbed enough water to break down and liberate each individual starch molecule.

These starch molecules are extremely long and hydrophilic (they love water). They will bind a lot of water as a result, which will thicken liquids. This explains why starch is a common thickener. Almost usually, potato starch is employed in some capacity because of its ability to thicken liquids.


This swelling and breaking process cannot be stopped. Your potato starch sauce or liquid won’t return to its former consistency if you cool it down. It won’t, however, continue to be freshly prepared. Instead, a process known as retrogradation will occur once the cooked potato starch has cooled. The starch partially recrystallizes during this process. In comparison to other carbohydrates, potato starch is known to retrograde particularly significantly.

What can Potato Starch be Used for?

Potato starch is frequently utilized as a thickening, just like the majority of other starches. It may be found being used in sauces or soups. Additionally, you can find it being used in place of (part of) wheat flour in cookies and cakes (we tested that more extensively here). Compared to using simply plain wheat flour, this usually results in very brittle (sandy) cookies and lighter cakes (thanks to the lower protein content).

But did you know that some of the biggest consumers of potato starch aren’t food producers? On the contrary, the paper and glue (adhesives) industries both heavily rely on potato starch!
