Food preservation made easy for households with "Deliéa", an Air Liquide innovation

Air Liquide Japan Ltd (Air Liquide Japan, hereafter) has developed a product called “Deliéa”, bringing to households “Modified Atmosphere Packaging” technology, a preservation method widely used in the industry.

Modified Atmosphere Packaging is widely used for food process and logistics industries to extend shelf life and help preserve the shape of foods. Air Liquide is a global leader in the technology, offering products and services for different types of food ranging from meat, fish, fruits, vegetables to dairy products. Advantages of this technology include: no chemical additives are necessary to preserve food, and no excessive deflation is required, so aroma and shape of sensitive foods like strawberry and cakes can be maintained.

“Deliéa” technology combines the use of a gas injector and a storage bag. Two different solutions, with 2 types of gases and bags, are available depending on the type of food concerned (meat & fish / vegetables & fruits). The process consists in placing the food inside the special storage bag, seal it, connect the hand-held device to the bag in order to fill it with the appropriate preservation gas. Small gas cylinder cartridges are available for easy refill. The gas composition and material selection for storage bag leverages Air Liquide long-time expertise in “Modified Atmosphere Packaging” for the industry.

This innovation was inspired by the evolution of food consumers behavior, with growing concern regarding food waste and new lifestyle induced by the growing number of double-career or single-person households.

Deliéa is available through online pre-sale ( from July 11th to August 24th.

Shiro Yahara, President and CEO, Air Liquide Japan, commented: “Air Liquide has been active in Modified Atmosphere Packaging technology from its early stage of development, and gained extensive expertise in Japan and worldwide, through offering service to our customers. As social interest in reducing food waste and food safety attention grows, we have developed “Deliéa” to make this technology available for household use.”
