Air Products will showcase how the use of industrial gases in food processing applications can help natural, organic and healthy food producers increase productivity and improve food quality at the Natural Products Expo West in Anaheim, California, from 8th to 10th March.

Show attendees are invited to stop by Air Products’ booth N343, where the Tier One company will highlight its Freshline® solutions using liquid nitrogen (N2) and carbon dioxide (CO2), which provide numerous benefits in food freezing and chilling applications. Due to the extremely cold temperatures of these cryogenic gases, food products can be chilled or frozen in minutes instead of the hours traditionally required with alternative systems. This rapid freeze results in smaller product weight losses and ensures moisture and quality are maintained longer.

Cryogenic gases are also beneficial in grinding nutraceuticals, spices and other ingredients. During grinding operations, liquid N2 can be used to eliminate frictional heat to help improve mill throughput and grind consistency. This also helps prevent the loss of flavor and aroma components. 

Air Products will highlight other applications that use food-grade industrial gases, such as modified atmosphere packaging (MAP). MAP is a process where the breathable atmosphere in a package is replaced with pure gas, like N2, or a gas mixture to extend the shelf life of food. Because food products spoil in different ways—whether through microbial growth, discoloration, oxidation or moisture loss—industrial gases can be added into the package to change the composition of the air around the food, enabling food to look, smell and taste good longer.

As a leader in cryogenic technology applications, Air Products operates state-of-the-art food and grinding labs in Allentown, Pa., where the company can test a customer’s product on production-scale equipment to help determine the feasibility of using cryogenics in their process, quantify the cost versus benefits of using cryogenics, and optimize their food processing operation.
