Specialty Gases for the Portland Food & Beverage Industry

Industrial and specialty gases have been  used for years in the Portland food industry. Typically, these gases find numerous applications, including use in flash freezing, beverage carbonation, fruit ripening, and shelf-life extension.

PurityPlus® gases graded and prepared for food packaging leave their imprint on just about all of the food industry, covering 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 commonly employed 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 facilitates practically immediate freezing to temperatures of -20 degrees or lower, and that quick temperature diminishment protects the flavor and taste of the product which otherwise can be lost with old-fashioned freezing apparatus. We at Cryo-Source can give you more information on the freezers and refrigerators typically used for these purposes – and even provide you with the units most appropriate for your operations.

The use of carbon dioxide for beverage carbonation and dispensing has more than a century and a quarter of precedence. Today, literally tens of thousands of point-of-use beverage dispensers depend on beverage-grade CO2 provided in cylinders of different sizes. This helps maintain a top-grade final product because it’s carbonated by a clean gas that has no taste or smell by virtue of its preparation. Today’s local microbreweries, restaurants, and taverns, in particular – in addition to world-class breweries – most often call for PurityPlus beverage-grade carbon dioxide for beer dispensing. Just as desired are special mixtures of nitrogen and carbon dioxide because they facilitate pouring many of those oft-requested Porter-style dark beers.

At the same time soft-drink and beer packaging and beer dispensers using carbon dioxide are generally taken for granted worldwide, a number of other foods and beverages use PurityPlus specialty gases in a manner that the consumer doesn’t see. A classic case in point is fruit ripening. For more than fifty years, High Purity and C.P.-Grade ethylene have been integral elements of the banana supply chain internationally. Green bananas are harvested, packaged, delivered, and inventoried at carefully controlled temperatures. The giant grocery distributors acquire this fruit and send it to ripening chambers that allow a deliberate flow of ethylene. This facilitates the natural ripening process to bring about that golden-yellow glow we look for when we go to purchase bananas from the grocery or produce store.

Another major gas-consuming application consists of deploying nitrogen to displace oxygen and moisture in product packaging, which prolongs shelf life and enhances product appearance. The most recognized process uses High Purity nitrogen with very low moisture and oxygen content to safeguard a broad range of products, from coffee and breakfast cereals to potato chips, nuts, and other salty snacks. More complex, specially prepared mixtures of High Purity nitrogen, carbon dioxide, and oxygen are used to produce what most in the industry call Modified Atmospheric Packaging (MAP).

The applications offered here barely scratch the surface of the countless ways in which food and beverage manufacturers and packaging enterprises use Purity Plus gases and equipment in the United States and Canada. Our people know well how to utilize food industry gases economically. Better yet, we’re enthusiastic about working with you to help prolong the shelf life and upgrade the appearance of your products.
