Specialty Gases for the Denver Food & Beverage Industry The use of industrial and specialty gases by the Denver food industry is well established. Normally, these gases find many applications, including use in flash freezing, beverage carbonation, fruit ripening, and shelf-life extension. PurityPlus® gases analyzed and prepared 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 technique makes possible near-immediate freezing to temperatures of -20 degrees or colder, and that quick temperature decrease safeguards the flavor and taste of the product which otherwise can fade with standard freezing techniques. Rocky Mountain Air Solutions’s experts know a great deal about the freezers and refrigerators these processes demand. We also sell freezers and refrigerators and can provide the units that are right for your operations. The use of carbon dioxide for beverage carbonation and dispensing goes back more than 125 years. Today, literally tens of thousands of point-of-use beverage dispensers depend on beverage-grade CO2 shipped in cylinders of different sizes. This ensures a quality final product given that it’s carbonated by a clean gas that’s taste and odor free, thanks to the way its prepared. Today’s local microbreweries, restaurants, and taverns, in particular – in addition to world-class breweries – tend to demand PurityPlus beverage-grade carbon dioxide for beer dispensing. Just as preferred are special mixtures of nitrogen and carbon dioxide because they help bartenders do a better job of correctly pouring most of those popular Porter-style dark beers. Though soft-drink and beer packaging and beer dispensers using carbon dioxide are pretty much par for the course worldwide, many other foods and beverages use PurityPlus specialty gases in a way that’s frequently unseen by the consumer. A superb example is fruit ripening. For more than fifty years, High Purity and C.P.-Grade ethylene have been indispensible parts of the banana supply chain internationally. Green bananas are harvested, packaged, shipped, and inventoried at carefully regulated temperatures. The giant grocery distributors acquire this fruit and place it in ripening chambers that allow a controlled flow of ethylene. This boosts the natural ripening process to produce that golden-yellow glow we want when we purchase bananas from the grocery or produce store. Another large gas-consuming application entails employing nitrogen to displace oxygen and moisture in product packaging, which increases shelf life and improves product appearance. The most common process makes use of High Purity nitrogen with very low moisture and oxygen content to protect a wide variety of products, from coffee and breakfast cereals to potato chips, nuts, and other salty snacks. More complex, specially prepared formulations of High Purity nitrogen, carbon dioxide, and oxygen are deployed to fabricate what’s commonly called Modified Atmospheric Packaging (MAP). The examples presented here inadequately address the myriad ways in which food and beverage manufacturers and packaging enterprises use Purity Plus gases and equipment in the United States and Canada. Our staff certainly knows how to use food industry gases cost-efficiently. Better yet, we’re eager to work with you to help extend the shelf life and upgrade the appearance of your products.
