At Absstem, we understand the importance of maintaining high-quality standards when it comes to producing fried snacks. One of the most critical factors that can affect the taste, texture, and overall quality of fried snacks is the level of nitrogen purity used during the production process. In this article, we’ll provide you with a comprehensive guide on the importance of PSA nitrogen purity for fried snacks.

What is PSA Nitrogen Purity?

Pressure Swing Adsorption (PSA) Nitrogen Purity is a process used to generate nitrogen gas from compressed air. The process works by separating oxygen and other gases from compressed air, producing high-purity nitrogen gas that is suitable for various applications. The purity level of nitrogen gas is measured in terms of the concentration of nitrogen in the gas mixture. The higher the concentration of nitrogen, the purer the gas.

The Importance of PSA Nitrogen Purity in Fried Snacks Production

The use of high-purity nitrogen in fried snack production has several benefits. Firstly, it helps to prevent oxidation, which can cause the snacks to become stale and lose their flavor over time. Secondly, nitrogen gas can prevent the formation of acrylamide, a chemical compound that forms when certain foods are cooked at high temperatures. Acrylamide has been linked to health problems, such as cancer, and reducing its formation in fried snacks is essential for consumer safety. Lastly, high-purity nitrogen gas can also help to improve the texture and appearance of fried snacks, making them more visually appealing to consumers.

Factors that Affect PSA Nitrogen Purity

Several factors can affect the purity of nitrogen gas produced through PSA, including the quality of compressed air used, the design of the PSA system, and the operating conditions of the system. To ensure that the nitrogen gas used in fried snack production is of the highest quality, it’s crucial to have a well-designed PSA system that is properly maintained and operated.

At Absstem, we use state-of-the-art PSA systems that are designed to produce high-purity nitrogen gas consistently. Our systems are regularly maintained and operated by trained professionals to ensure that the nitrogen gas we produce meets the highest quality standards.

Benefits of Using High-Purity Nitrogen in Fried Snacks Production

  • Using high-purity nitrogen gas in fried snack production can offer several benefits to manufacturers and consumers alike. Some of the most significant benefits include:
  • Enhanced Flavor: High-purity nitrogen gas can help to preserve the flavor of fried snacks, making them more enjoyable to consume.
  • Longer Shelf Life: Nitrogen gas can prevent the oxidation of fried snacks, which can extend their shelf life and reduce waste.
  • Improved Appearance: Nitrogen gas can help to improve the texture and appearance of fried snacks, making them more visually appealing to consumers.
  • Health Benefits: By reducing the formation of acrylamide in fried snacks, the use of high-purity nitrogen gas can help to promote consumer health and safety.


In conclusion, the use of high-purity nitrogen gas is essential for producing high-quality fried snacks. By reducing oxidation, preventing the formation of acrylamide, and improving the appearance of fried snacks, high-purity nitrogen gas can offer several benefits to both manufacturers and consumers. At Absstem, we’re committed to using the highest quality PSA nitrogen purity to produce fried snacks that meet the highest quality standards
