Starch Vs Flour – What’s The Difference?

Last Updated on November 8, 2022

When baking, some recipes call for flour or starch. Which should I choose? Why are they two very different things?

In cooking, we often refer to flours as starches. Starch is a type of carbohydrate found in plant foods such as potatoes and corn (among other types). Starches are typically composed of long chains of glucose molecules. They don’t dissolve well in water but rather form gels and films. This makes them great thickeners and stabilizers.

Starch is a complex carbohydrate that contains long chain molecules called polysaccharides. These molecules consist of simple sugars linked together in long chains. When cooked, these compounds swell and gelatinize, thickening sauces, gravies, soups, and stews.

Flour is an ingredient used in baking that usually contains wheat, rye, barley, or oats (or any combination thereof).

Flour is the end product of grain processing. There are many types of flour produced in different countries around the world. Generally speaking, they all have similar nutritional values and consist primarily of carbohydrates (glucose). They may be further processed into various products including bread, pasta, crackers, cakes, cookies, pie crusts, tortillas, noodles, waffles, pancakes, pasta, biscuits, and dumplings.

Starch Vs Flour – Proper Usage

There are many uses for flour and starch, but here we will concentrate on their differences. Both types of ingredients are used to thicken sauces and batters, but there are some key differences.

Flour is made up of gluten proteins that give bread dough structure. When you add water to flour, it forms a slurry called a batter. This is what gives bread its characteristic texture. You can use whole wheat white flour to make which contains more protein than white flour. Batter made with whole wheat flour tends to be thicker because it has more protein.

Starches are carbohydrates that come from plants like corn, potatoes, rice, etc. Starches are often added to foods such as soups, stews, gravies, and casseroles. Unlike flour, starches do not form a slurry when mixed with liquid. Instead, they absorb moisture and swell into long chains. The starches break down and release energy when you cook food containing starches. This helps to keep the food warm without adding additional calories.

Both flour and starch can be used interchangeably in recipes. However, there are times when one type of ingredient works better than another. For example, when making pancakes, you want a thick batter. If you mix too much flour into the batter, the pancake won’t rise properly. On the other hand, when making cookies, you don’t want a very thick batter. A cookie needs to spread quickly over the baking sheet. In this case, you’ll want to use a mixture of flour and starch.

Making Sauces

Starch is often confused with flour. But there are some differences between the two ingredients. Flour is used to make bread, pasta, pizza dough, cookies, cakes, etc. While starch is used to make sauces, gravies, soups, stews, and many other dishes. So what makes one ingredient better than another? Let’s find out.

Flour vs. Starch – processing

Both flour and starch are carbohydrates. They both provide energy for our bodies. In fact, we use about half of the total calories we consume every day. This includes carbs from foods such as grains, vegetables, fruits, beans, nuts, seeds, dairy products, meat, fish, eggs, and even alcohol.

The difference between flour and starch lies in how they are processed. When you buy a bag of flour, you are purchasing a mixture of different types of starches. These include cornstarch, potato starch, tapioca starch, rice starch, and arrowroot starch. Each type of starch has its unique properties. For example, cornstarch is great for thickening sauces and gravies because it absorbs water easily. Potato starch works well for mashing potatoes and adding flavor to mashed potatoes. Arrowroot starch gives baked goods a nice texture. Rice starch helps bind together the dough. Corn starch has no added sugar or salt. You can add spices, herbs, and seasonings to your sauce or gravy without affecting the taste.

Why Use One Over the Other?

You might want to choose one over the other for several reasons. First, let’s look at the advantages of each. Flour is excellent for making bread dough, pie crust, and cookies. But it doesn’t work well for frying. When food is fried in oil, the proteins in the flour absorb water and swell up like balloons. This causes the batter to become heavy and greasy. To avoid this problem, use cornstarch or potato powder instead of flour. They are both excellent for frying because they don’t absorb moisture and make a light, airy crumb.

Potato starch is best used for deep frying. It absorbs less heat than cornstarch and gives a lighter color to the finished product.

Starch Vs Flour – Nutritional Value

Corn flour is often used in place of cornstarch because it costs about half as much per pound. However, corn flour does contain fewer nutrients than corn starch. When you bake something like cookies or bread, the starches are what provide most of the energy. In fact, corn starch offers twice the amount of calories as corn flour. This is why corn flour is best suited for making things like pancakes, waffles, muffins, biscuits, etc.

Corn Flour vs Corn Starch Nutritional Data

The difference between corn flour and corn starch is pretty simple: one is made from corn, and the other isn’t. But what does it mean for you? Let’s break down the nutritional data to see how much protein and fiber each provides.

Nutrient | Corn Flour | Corn Starch

Calories | 12 per cup | 10 per cup

Fat | 0 g | 0 g

Carbohydrates | 3.5 g | 2.7 g

Fiber | 0 g | 0.1 g

Protein | 4.4 g | 5.9 g

Now you know the proper and exact usage of flour and starch for your recipes to make them tastier and perfect.

Starch Vs Flour – How They’re Made

Starch is a type of carbohydrate found in plants. It is composed of long chains of glucose molecules linked together. Glucose is the main source of energy for humans and animals. In order to digest starch, our bodies break down the glucose into smaller units called maltodextrins. These maltodextrins are then absorbed into the bloodstream where they are used as fuel. Flour is ground from grain kernels such as wheat, corn, oats, barley, rye, millet, sorghum, buckwheat, amaranth, quinoa, teff, and other types of cereal grasses. Flours are typically milled into finer particles than starches. This allows flour to absorb moisture better and become softer when cooked.

What is Starch?

Starch is a type carbohydrate found in plants. It is composed of long chains polysaccharides of glucose molecules linked together glucosidic bonds. Glucose is the major source of energy for humans. In order to digest starches, our bodies break down these polysaccharides into smaller units called maltodexters. These maltodexters are then absorbed into the blood stream where they are used as energy.

What is Flour?

Flour is a mixture of starch and proteins. It is used to make breads, pastries, cookies, and other baked goods. Flours are usually ground from wheat, barley, rye, corn, oats, millet, buckwheat, sorghum, and cassava.

Starch Vs Flour – Proper Usage

Starch is a carbohydrate found in plants. It is composed of chains of glucose molecules joined together. Glucose is the main sugar in our blood stream. It is used to produce energy in cells. Flour is a powdery substance that contains protein and starch. It is obtained from grain such as wheat, maize, rice, oatmeal, and potato.

Making Sauces

Sauce is a liquid condiment that is added to dishes to enhance flavor. Sauce is usually served separately from the dish itself, but sometimes it is poured into the dish while serving. There are many types of sauces available. These include ketchup, mustard, salad dressing, gravy, tomato sauce, honey, syrup, and jam.


Frying is a method of cooking food using hot fat oil, shortening, butter or other cooking medium such as steam. It is used extensively in restaurants and fast food outlets, where it is known as shallow frying. Deep frying is done in a pan or wok filled with hot oil or fat.

Starch Vs Flour – Nutritional Value

Starch is a carbohydrate found in plants. It is composed of chains of glucose molecules linked together by bonds called glycosidic linkages. Glucose is a monosaccharide a single sugar molecule consisting of six carbon atoms joined by oxygen atoms. It is the primary source of energy for many organisms. Flour is ground from grain seeds, usually wheat, rye, barley, oats, corn, millet, sorghum, buckwheat, amaranth, teff, quinoa, and rice. It contains protein, carbohydrates, fats, vitamins, minerals, and fiber.

Corn Flour vs Corn Starch Nutritional Data

Corn flour is made from corn kernels that have been dried, milled, and degerminated. It is used as a thickening agent in baked goods and other products. Cornstarch is made from corn kernels after being cooked, cooled, and degerminate. It is used as thickeners in sauces and gravies, soups, and stews.

Can I use starch instead of flour?

Starch is found in many different types of foods. It is used to thicken sauces, soups, gravies, and other foods. Starch is also added to breads and pastries to give them structure and help them hold together. In addition to being used to thicken foods, starch is also used to make dough easier to handle. Starch is usually measured in grams per 100 grams of flour. One cup of flour contains about 140 grams of starch.

Is flour a starch?

Starch is composed of glucose molecules linked together into long chains called polymers. Glucose molecules are the building blocks of carbohydrates. Starch is found in many plants, such as corn, wheat, potatoes, peas, beans, and oats. It is the main source of energy for animals. In humans, starch is used for storage and is converted to sugar glucose during digestion.

How much of flour is starch?

Starch is composed of two main components: amylose a long chain carbohydrate and amylopectin a short chain carbohydrate. Amylose forms a gel structure when heated, while amylopectin does not. This difference in behavior allows us to distinguish between starch and gluten. Gluten is formed from proteins called gliadins, which form a network that traps water molecules and prevents the starch granules from swelling. Starch is found in many types of plants, but wheat, corn, potatoes, and tapioca are the primary sources of starch in our diet.

What percent of flour is starch?

Starch is a carbohydrate that comes from plants. It is composed of long chains of glucose molecules. Starch is found in many different types of plant products such as corn, wheat, potatoes, beans, peas, oats, barley, rice, tapioca, and cassava.

How much starch is in plain flour?

Yes, but not all starches are created equal. Starch is a carbohydrate found naturally in many plants, such as corn, potatoes, wheat, tapioca, arrowroot, and cassava. It is used in baking, thickening sauces, and other applications. In addition to being a natural ingredient, starch is inexpensive and easy to obtain. However, it does have limitations. For instance, it doesn’t absorb liquid well, making it difficult to thicken soups, gravies, and sauces. Also, it tends to clump together, making it hard to mix into doughs. This is why bread recipes call for flour, which absorbs liquids better and helps prevent the formation of lumps.
