Specialty Gases for the Indianapolis Food & Beverage Industry

Industrial and specialty gases have long been used in the Indianapolis food industry. Usually, these gases find a lot of applications, including use in flash freezing, beverage carbonation, fruit ripening, and shelf-life extension.

PurityPlus® gases authorized and prepared for food packaging touch almost the whole food industry, protecting or enhancing 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 nearly immediate freezing to temperatures of -20 degrees or lower, and that quick temperature decrease saves the flavor and taste of the product which otherwise can become unpleasant with standard freezing apparatus. We at American Welding & Gas, Inc. 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 goes back more than 125 years. Today, literally tens of thousands of point-of-use beverage dispensers rely on beverage-grade CO2 delivered in cylinders that come in different volumes. This helps guarantee a superior final product since it’s carbonated by a clean gas that, by preparation and analysis, does not have any taste or odor. Modern local microbreweries, restaurants, and taverns, in particular – not to mention world-class breweries – most often insist on PurityPlus beverage-grade carbon dioxide for beer dispensing. Equally requested are special mixtures of nitrogen and carbon dioxide, given that they make it easier to properly pour many of those customer-pleasing Porter-style dark beers.

Even Though soft-drink and beer packaging and beer dispensers using carbon dioxide are found just about all over the world, a lot of other foods and beverages benefit from PurityPlus specialty gases in a manner 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 indispensible parts of the banana supply chain globally. Green bananas are harvested, packaged, delivered, and warehoused at carefully monitored temperatures. Major grocery distributors take possession of this fruit and place it in ripening chambers that introduce a deliberate flow of ethylene. This enhances the natural ripening process to bring about that golden-yellow glow that entices us to buy bananas from the grocery or produce store.

Another big gas-consuming application entails deploying nitrogen to displace oxygen and moisture in product packaging, which increases shelf life and spruces up product appearance. The most common process utilizes High Purity nitrogen with insignificant 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 used to manufacture what’s generally referred to as Modified Atmospheric Packaging (MAP).

The applications offered here hardly convey the wide-ranging ways in which food and beverage manufacturers and packaging enterprises use Purity Plus gases and equipment in the United States and Canada. Our staff is experts in how to use food industry gases cost-efficiently. Even better, we’re happy to work in partnership with you to help extend the shelf life and upgrade the appeal of your products.
