What Is Blanching Fries

What Is Blanching Fries?

In the process of frozen French fries processing, blanching fries is an important process, which is to heat the potatoes fries in boiling water or steam for a period of time.

What Are The Benefits Of Blanching Fries?

1. Remove excess starch

The blanching process can first help remove excess starch on the surface of potatoes through the action of hot water, which helps prevent the fries from sticking to each other during the subsequent frying process.

2. Inactivate enzymes and remove sugar

The blanching process can kill enzymes in potatoes and prevent the action of the fries’ own enzymes before frying, which causes changes in sugar content, thereby maintaining the flavor and color of the fries.

3. Improve the organizational structure of fries

Through blanching, some starch gelatinization can improve the organizational structure of fries, making the fries have better firmness and taste after frying.

4. Reduce the formation of acrylamide

The blanching process can reduce the formation of acrylamide during frying by reducing the content of reducing sugars and amino acid asparagine in fries, which is a substance that may be harmful to health.

5. Extend the storage life

The blanched fries are less likely to turn black during storage, which helps to maintain their appearance and quality.

Blanching Temperature Of French Fries

The temperature for blanching French fries is usually between 85℃ and 95℃. Higher temperatures can destroy enzyme activity more quickly, but may also cause the French fries to become overly soft.

Blanching Time Of French Fries

The blanching time of French fries is usually between 30 seconds and 2 minutes, depending on the thickness of the fries and the temperature.

Blanching for too long may cause the texture of the French fries to be too soft, which will affect the flavor, color, vitamins and minerals, and increase production costs.

Blanching for too short a time may not completely inactivate the enzymes, resulting in color and taste problems.
