How to Increase the Shelf Life of Food Products Nick Vasco | 4 minutes | March 20, 2025 Modified Atmosphere Packaging (MAP) is the most common way to increase the shelf life of food products, though other methods like cryogenic freezing and high-pressure packaging (HPP) can be used as advanced techniques when MAP does not suffice. This guide will explore the key benefits of different techniques to help you choose the right one. You’ll then learn about specific tips you should follow to maximize the shelf life of different food products. The Power of Modified Atmosphere Packaging (MAP) MAP works by replacing regular air with a carefully controlled mixture of gases like nitrogen and carbon dioxide. This way, it creates an environment where food stays fresh significantly longer than it would in a typical atmosphere. The right mix of industrial gases can triple or even quadruple the shelf life of many food products. For example, using nitrogen in packaging can reduce oxidation and prevent the growth of aerobic bacteria, while carbon dioxide helps inhibit microbial growth. This combination is particularly effective for meat products, where shelf life can be extended from only a few days to several weeks. Here are other examples of gas mixtures for food products: Food productsRecommended MAP gas mixtures (for retail use)Beef, goat, veal70% O2, 30% CO2Cod, catfish, sea bass30% O2, 40% CO2, 30% N2Bagels, croissants, vegetable breads50% CO2, 50% N2Apples, avocados, plums (and most other fruits)5% O2, 5% CO2, 90% N2 Source: Sorbent Systems Temperature Plays a Big Role in Extending Shelf Life Temperature is a key factor in food preservation. By combining MAP with the right temperature, you can create a highly effective preservation system. For example, keeping products at temperatures just above freezing (32-34°F) while using nitrogen-enriched packaging can extend shelf life by up to 400% for products like fresh-cut fruits and vegetables. Effective cold chain management requires industrial refrigeration systems powered by specialized gases. Many food processors rely on them because they consistently maintain precise temperatures. Advanced Technologies for Increasing Food Shelf Life In addition to traditional food preservation methods, several advanced technologies are being used for extending the shelf life of different foods. They often rely on industrial gases and specialized equipment to achieve optimal preservation conditions. Cryogenic freezing using liquid nitrogen is a perfect example. It offers ultra-fast freezing that preserves food quality better than traditional methods. This process creates smaller ice crystals, resulting in less cellular damage and better product quality upon thawing. Another emerging technology is high-pressure processing (HPP), which offers similar performance to traditional thermal processing when it comes to food preservation. This method is particularly effective for juice products and ready-to-eat meals, which shouldn’t undergo repeat temperature shifts. Tips for Effective Food Preservation Here are some tips for food preservation: Monitor and maintain optimal gas mixtures in MAP systems for different foods Ensure proper temperature control throughout the supply chain Regularly calibrate and maintain all preservation equipment Train staff on proper handling and storage procedures (e.g., using food-safe containers and keeping the storage area pest-free) Benefits of Effective Food Preservation The right preservation strategy can benefit your bottom line in many ways, such as: Maintaining product quality Reducing waste … and decreasing returns Food Preservation is Evolving As food preservation technology continues to evolve, industrial gases will keep playing an important role in extending shelf life. New developments in smart packaging and active packaging systems are already showing promise for even longer shelf life potential. Working with a reliable industrial gas supplier is crucial to always maximize the shelf life of your food products. By doing so, you ensure access to the pure gases needed for different preservation methods and expertise that can help you implement the right solution for each food product.

No, you cannot weld carbon steel, aluminum, or stainless steel with pure nitrogen because it causes severe porosity, arc instability, and brittle welds. The only exception is copper and certain copper alloys, where nitrogen actually provides adequate shielding. While nitrogen fails as a primary shielding gas, it has specific uses in welding operations – including …
