Specialty Gases for the Auburn Food & Beverage Industry

Using industrial and specialty gases is hardly new to the Auburn food industry. Normally, these gases find numerous applications, including use in flash freezing, beverage carbonation, fruit ripening, and shelf-life extension.

PurityPlus® gases assessed and provided for food packaging are ubiquitous in the food industry worldwide, benefiting such products as …

  • Red Meats
  • Poultry
  • Fresh Fruits
  • Salty Snacks
  • Peanut Butter
  • Carbonated Drinks
  • Beer and Wine
  • Processed Meats
  • Dairy Products
  • Dry & Dehydrated Foods
  • Prepared Foods
  • Bakery Foods
  • Fresh Vegetables

Liquid nitrogen and liquid carbon dioxide are used to freeze meats, including beef, pork, chicken and fish, both raw and partially prepared, as well as fruits, vegetables, ice cream, and baked goods. A gas-based process makes possible practically immediate freezing to temperatures of -20 degrees or lower, and that rapid temperature decrease saves the flavor and taste of the product which otherwise can fade with standard freezing techniques. We at Spec Air Specialty Gases can give you more information on the freezers and refrigerators these processes require – and even provide you with the units most appropriate for your operations.

The use of carbon dioxide for beverage carbonation and dispensing goes back more than 125 years. These days, literally tens of thousands of point-of-use beverage dispensers depend on beverage-grade CO2 provided in cylinders of different capacities. This helps guarantee a superior final product since it’s carbonated by a clean gas that’s taste and odor free, thanks to the way its prepared. Modern local microbreweries, restaurants, and taverns, especially – world-class breweries, besides – tend to call for PurityPlus beverage-grade carbon dioxide for beer dispensing. Equally requested are special mixtures of nitrogen and carbon dioxide, given that they facilitate pouring most of those famous Porter-style dark beers.

Though soft-drink and beer packaging and beer dispensers using carbon dioxide have become global features, a lot of other foods and beverages make use of PurityPlus specialty gases in a way that goes unnoticed by the consumer. A classic example is fruit ripening. For over fifty years, High Purity and C.P.-Grade ethylene have been seen as necessary elements of the banana supply chain internationally. Green bananas are harvested, packaged, delivered, and warehoused at carefully monitored temperatures. The preeminent grocery distributors get this fruit and transfer it to ripening chambers that introduce a precisely monitored flow of ethylene. This speeds up the natural ripening process to provide that golden-yellow glow we see when we buy bananas from the grocery or produce store.

Another major gas-consuming application consists of using nitrogen to displace oxygen and moisture in product packaging, which lengthens shelf life and spruces up product appearance. The most familiar process makes use of High Purity nitrogen with insignificant moisture and oxygen content to safeguard a great many products, from coffee and breakfast cereals to potato chips, nuts, and other salty snacks. To fabricate what’s best known as Modified Atmospheric Packaging (MAP), food processors use more complex, specially prepared formulations of High Purity nitrogen, carbon dioxide, and oxygen.

The applications recounted here only scratch the surface of the thousands of ways in which food and beverage manufacturers and packaging companies use Purity Plus gases and equipment in the United States and Canada. Our staff is very knowledgeable about how to use food industry gases cost-efficiently. Better yet, we’re happy to work in partnership with you to help increase the shelf life and enhance the appearance of your products.
