Increased scrutiny of food ingredients and the consumer’s desire for natural or healthy produce have motivated food processors to find novel ways of replacing chemical preservatives with natural ones.
Air Products’ modified atmosphere packaging (MAP) development team has discovered that combining natural compound vapours such as essential oils or aromas with MAP can give an enhanced aroma or flavour to packaged products.
Another benefit of the Freshline® Aroma MAPTM System is the extended shelf life of the product compared to standard MAP (when adding certain specific essential oils in the aroma vapour), offering the possibility to replace or remove chemical preservatives currently used.
As a consequence, Air Products’ R&D team created the Freshline® Aroma MAPTM System for food packaging.
The Freshline® Aroma MAPTM System allows you to seamlessly deliver precise amounts of volatile compounds (essential oils) into your MAP gas stream. This provides a tailored aroma to food products and potentially extends the product shelf life, depending on the compounds chosen.
How does it work?
Built on a skid on wheels, this system is easily and rapidly fitted onto the existing packaging line, between the MAP gas supply and the packaging machine.
Thanks to its pre-set parameters, the machine injects a precise and repeatable amount of aroma/active compounds into the gas flow. The mix of MAP gas and evaporated active/aroma compounds is then led to the packaging machine, where it is inserted in the packaging the same way it is done for standard MAP.
Air Products experts will then build, calibrate and install the Freshline® Aroma MAPTM System to the exact dosing rate needed depending on the compound used and desired end result.
