Specialty Gases for the Southern California Food & Beverage Industry

Industrial and specialty gases have a long history in the Southern California food industry. Normally, these gases find many applications, including use in flash freezing, beverage carbonation, fruit ripening, and shelf-life extension.

PurityPlus® gases rated and delivered for food packaging are ubiquitous in the food industry worldwide, 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 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 procedure allows almost immediate freezing to temperatures of -20 degrees or lower, and that rapid temperature reduction safeguards the flavor and taste of the product which otherwise can fade with traditional freezing apparatus. We at WestAir Specialty Gases and Equipment can give you all the facts you need on the freezers and refrigerators typically used for these purposes – and even get you 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. Nowadays, literally tens of thousands of point-of-use beverage dispensers depend on beverage-grade CO2 shipped in cylinders that come in varying volumes. This insures a superior final product due to the fact that it’s carbonated by a clean gas that’s taste and odor free by preparation and analysis. Contemporary local microbreweries, restaurants, and taverns, especially – in addition to world-class breweries – will demand PurityPlus beverage-grade carbon dioxide for beer dispensing. Just as requested are special mixtures of nitrogen and carbon dioxide, given that they help bartenders do a better job of correctly pouring most of those frequently demanded Porter-style dark beers.

Never mind that soft-drink and beer packaging and beer dispensers using carbon dioxide are almost universally recognized, a number of other foods and beverages employ PurityPlus specialty gases in a manner that tends to be invisible to the consumer. A good case in point is fruit ripening. For better than fifty years, High Purity and C.P.-Grade ethylene have been indispensible components in the banana supply chain around the world. Green bananas are harvested, packaged, delivered, and warehoused at carefully regulated temperatures. Major grocery distributors get this fruit and move it into ripening chambers that allow a controlled flow of ethylene. This heightens the natural ripening process to bring about that golden-yellow glow that entices us to purchase bananas from the grocery store.

Another large gas-consuming application entails employing nitrogen to displace oxygen and moisture in product packaging, which prolongs shelf life and makes the product look better. The best-known process makes use of High Purity nitrogen with limited moisture and oxygen content to preserve an extensive array of products, from coffee and breakfast cereals to potato chips, nuts, and other salty snacks. To manufacture what’s commonly called Modified Atmospheric Packaging (MAP), food processors make use of more complex, specially prepared mixtures of High Purity nitrogen, carbon dioxide, and oxygen.

The applications outlined here hardly convey the many 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 experts in the cost-effective use of food industry gases. Best of all, we’re enthusiastic about working with you to help increase the shelf life and improve the look of your products.
