Specialty Gases for the Fresno Food & Beverage Industry Industrial and specialty gases have long been used in the Fresno 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 assessed and dedicated for food packaging leave their imprint on just about all of the food industry, 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 enables practically immediate freezing to temperatures of -20 degrees or colder, and that rapid temperature diminishment preserves the flavor and taste of the product which otherwise can fade with old-fashioned freezing equipment. Look to Fresno Oxygen & Welding Supplies/Barnes Welding Supply for authoritative details on the freezers and refrigerators used in these processes. Not only that, but we can also deliver the freezers and refrigerators you need. 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 rely on beverage-grade CO2 provided in cylinders of varied dimensions. This ensures a top-grade final product since it’s carbonated by a clean gas that, by preparation and analysis, does not have any taste or odor. Contemporary local microbreweries, restaurants, and taverns, especially – world-class breweries, besides – typically call for PurityPlus beverage-grade carbon dioxide for beer dispensing. Just as favored are special mixtures of nitrogen and carbon dioxide since they facilitate pouring a lot of those popular Porter-style dark beers. At the same time soft-drink and beer packaging and beer dispensers using carbon dioxide are found practically everywhere in world, a number of other foods and beverages employ PurityPlus specialty gases in a way that the consumer doesn’t see. A classic case in point is fruit ripening. For fifty years or so, High Purity and C.P.-Grade ethylene have been indispensible components in the banana supply chain globally. Green bananas are harvested, packaged, shipped, and stored at carefully monitored temperatures. Big grocery distributors get this fruit and transfer it to ripening chambers that introduce a precisely monitored flow of ethylene. This boosts the natural ripening process to create 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 extends shelf life and enhances product appearance. The best-known process uses High Purity nitrogen with very low moisture and oxygen content to preserve an extensive array of products, from coffee and breakfast cereals to potato chips, nuts, and other salty snacks. More complex, specially prepared combinations of High Purity nitrogen, carbon dioxide, and oxygen are deployed to produce what’s best known as Modified Atmospheric Packaging (MAP). The examples recounted here don’t even begin to convey the thousands of ways in which food and beverage manufacturers and packaging operations use Purity Plus gases and equipment in the United States and Canada. Our professionals are experts in how to use food industry gases cost-efficiently. What’s more, we’re anxious to work with you to help increase the shelf life and improve the look of your products.
