What are the benefits of corn starch, and how it differs from potato

Starch is a natural thickener, it is used to make jelly and sauces. In Russia, the most popular potato, but there are other types that differ in chemical composition and have their own advantages and disadvantages. Let's figure out which starch is better - potato or corn.

What it is

What are the benefits of corn starch, and how it differs from potato

Potato carbohydrate is obtained from tubers by washing and grinding. It consists of amylopectin and amylose. If you rub it between your fingers, you can feel a slight crunch of small particles. Upon contact with cold water, the product does not dissolve, but forms a viscous bulk - paste.

The product belongs to the group of polysaccharides, it contains high molecular weight carbohydrates that serve as structural components of cells and tissues.

What does it look like

It is a fine free-flowing white powder. When diluted, it does not change the color of water, juice or sauce, so it is most often used as a thickener in the preparation of transparent liquid products. It has a weakly expressed specific taste - this is taken into account when added to jelly and sauces.

  3. Reduces the amount of bad cholesterol in the blood and removes excess fluid from the body.

  2. Excessive consumption of the product leads to an increase in blood sugar levels and hormonal disorders.
  3. Potato starch contains gluten, so it is contraindicated for people with celiac disease.

Corn starch

Grain-derived starch corn, more suitable for cooking where high viscosity is not required. For example, creams and soups will turn out to be stringy and liquid, and adding it to baked goods makes the dough more fluffy.

What it is

In corn kernels, starch is formed as a result of photosynthesis. 90% consists of complex carbohydrate compounds, also contains proteins, fats and vitamins. Scope of application:

  1. Add to sauces, dressings, yoghurts, mashed potatoes, etc.What are the benefits of corn starch, and how it differs from potato
  2. Used as an emulsifier in spreads and margarine.
  3. Add to sausages to reduce moisture.

There are two types:

  • simple is obtained by soaking in sulfuric acid, grinding and drying the grains;
  • modified - by additional processing of simple.

What does it look like

It is a loose, odorless yellowish powder. A quality product tastes like corn, but without the pronounced taste of grains. Cornstarch is very similar to flour, which is why they are used interchangeably. Swells quickly in hot and cold water and becomes viscous.

  2. High-calorie, therefore, contraindicated in obesity.

There are two types of cornstarch:

  • natural is obtained from fruits and vegetables;
  • refined - by chemical processing, therefore, with frequent use, it harms the body.

How are they similar?

The chemical composition of corn and potato starch is practically the same - they both consist of amylose and amylopectin.

The consistencies are also similar: both products are in powder form with a slight odor and a faint taste. Both form gel-like structures, although potato has more stickiness.

What is the difference between corn starch and potato

Visually, corn starch differs from potato in structure and color. Processed potatoes acquire a snow-white color and fine-crystalline structure, while corn becomes yellowish-white and resembles flour in consistency.

When corn starch is added to hot water, a cloudy consistency is obtained, and potato starch does not change the color of the water. Heating the second produces a thick, sticky paste, while the former remains practically liquid and can restore its structure.

Attention! The lack of gluten in cornstarch allows it to be consumed even by those on a gluten-free diet.

Is it possible to replace one with another

It is impossible to replace one type of starch with another. Unlike corn, potato is a strong thickener. For example, if you add it to the dough instead of corn dough, it will turn out to be too thick and tight.

If corn starch is added to the jelly instead of potato starch, it will be too liquid. The color of these products also differs - corn colors clear liquids.

Where is what starch is used

What are the benefits of corn starch, and how it differs from potato

Corn starch is widely used in cooking and confectionery. When added to the dough, a less dry and more tender biscuit is obtained.

The polysaccharide derived from corn kernels is less viscous than potato polysaccharides, gives a smooth consistency and is great for making liquid sauces and desserts.

Potato starch forms a more viscous paste and is used for making transparent cream soups and jelly. Also, this product absorbs excess liquid, so it is added when baking fruit and curd cakes.
