Gas Solutions for Food & Hospitality
The food and hospitality industries in Australia are vibrant and diverse, reflecting the nation’s rich cultural tapestry and culinary innovation. From bustling cafes and gourmet restaurants to quaint bakeries and food markets, Australia offers a range of dining experiences that cater to a wide variety of tastes and preferences. Known for its emphasis on quality, sustainability, and farm-to-table practices, the Australian food industry prides itself on using fresh, locally sourced ingredients to create delicious and memorable dishes. Industrial gases play a crucial role in processes ranging from food preservation and packaging to beverage carbonation and culinary applications.
What Gases Are Used in the Food and Hospitality Industry?
The food and hospitality industry relies on various gases to optimise the storage and preservation of ingredients, increase the efficiency of processes, and in the production of food and beverages. Here’s a breakdown of the gases commonly used in food and hospitality:
- Carbon Dioxide (CO2)
Carbon dioxide is essential for carbonating beverages, preserving food, and creating dry ice for cooling and transportation. It is widely used in the production of soft drinks, beer, and sparkling water, and in modified atmosphere packaging (MAP) to extend the shelf life of perishable foods. - Nitrogen (N2)
Nitrogen is used for inerting, purging, and blanketing in food packaging to prevent oxidation and spoilage. It is also used in cryogenic freezing and chilling processes to preserve the quality and freshness of food products. - Oxygen (O2)
Oxygen is used in controlled atmosphere packaging to maintain the freshness of fruits and vegetables. It is also employed in aquaculture to oxygenate water, ensuring optimal conditions for the growth and health of aquatic organisms. - Argon (Ar)
Argon is used in modified atmosphere packaging (MAP) to displace oxygen and extend the shelf life of food products. It helps maintain the colour, flavour, and texture of packaged foods.
Applications of Industrial Gases in Food and Hospitality
Beverage Carbonation
Carbon dioxide is the primary gas used for carbonating beverages. It is dissolved in water under pressure to create carbonated drinks such as soft drinks, beer, and sparkling water. Carbon dioxide is also used in dispensing systems for draft beer and soda fountains, ensuring consistent carbonation and quality of beverages served in restaurants, bars, and cafes.
Food Preservation and Packaging
Modified atmosphere packaging (MAP) is a common application of industrial gases in the food industry. Gases such as carbon dioxide, nitrogen, and argon are used to create a controlled atmosphere inside food packaging, extending the shelf life of perishable products by inhibiting the growth of spoilage microorganisms and preventing oxidation. This process helps maintain the quality, flavour, and appearance of fresh produce, meat, dairy products, and baked goods.
Aquaculture
In aquaculture, oxygen is used to oxygenate water in fish farms, ensuring optimal conditions for the growth and health of fish and other aquatic organisms. Adequate oxygen levels are essential for maintaining water quality, preventing stress, and promoting efficient feed conversion. Oxygenation systems are employed to deliver dissolved oxygen to the water, supporting healthy and productive aquaculture operations.
