A recently granted patent (Publication Number: US11772070B2) describes a food package designed to control or remove odors caused by amines. The package is a closed system with an internal volume and head space. It contains an amine-absorbent element made up of ammonium-exchanged mordenite type zeolites with a Si/Al atomic ratio between 5 and 20. These zeolites are present in the package in an amount between 2 µg and 50 µg per gram of weight of the amines-releasing food. The zeolites are in the form of powders with a particle size distribution (X90) between 0.2 and 10 µm.
The patent also mentions additional components of the amine-absorbent element. It can include ZnO-doped Faujasite type zeolites with a Si/Al atomic ratio between 2 and 30, present in an amount between 1 µg and 40 µg per gram of weight of the amines-releasing food. Furthermore, it can contain CuO-doped ZSM-5 type zeolites with a Si/Al atomic ratio between 10 and 50, present in an amount between 1.5 µg and 40 µg per gram of weight of the amines-releasing food.
The powders containing the zeolites are contained in a bag, which is composed of various materials such as low density polyethylene (LDPE), high density polyethylene (HDPE), polypropylene (PP), ethylene-vinyl acetate (EVA), polystyrene (PS), styrene-ethylene-butylene-styrene (SEBS), polylactic acid (PLA), polyesters, and biopolyesters. The bag can be placed either in the internal volume or the head space of the food package.
This patent provides a solution for controlling or removing odors caused by amines in food packages. By incorporating specific zeolites with the appropriate atomic ratios and particle sizes, the amine-absorbent element effectively captures and neutralizes the odorous compounds. The use of different zeolite types and compositions allows for customization based on the specific needs of different food products. The inclusion of a bag containing the zeolite powders ensures efficient distribution and contact with the amines-releasing food. The choice of bag material offers flexibility and compatibility with various packaging materials. Overall, this patented food package offers a practical and effective solution for odor control in the food industry.
