Food packaging arrangement
A food packaging arrangement ( 1 ) comprising a packaging ( 2 ) and a chemical composition ( 4 ) which, by reaction with a breakdown product of the food ( 3 ) in question, forms a light-emitting or fluorescent compound or emits light.
1. A food packaging arrangement, comprising:
a packaging ( 2 ); and
a chemical composition ( 4 ) which is configured to undergo a reaction with a breakdown product of the food ( 3 ) in question and to form a light emitting or fluorescent bioluminescent compound or emits light, characterized in that the chemical composition ( 4 ) contains reduced flavin mononucleotide, the breakdown product of the food ( 3 ) is an aldehyde, and the chemical composition ( 4 ) further comprises an aldehyde converting enzyme.
2. The food packaging arrangement according to claim 1 , characterized in that the packaging ( 2 ) is light-tight.
3. The food packaging arrangement according to claim 2 , characterized in that the packaging ( 2 ) comprises an exposable window ( 5 ) through which light can enter and exit.
4. The food packaging arrangement according to claim 1 , additionally comprising a buffer.
5. The food packaging arrangement according to claim 1 , characterized in that the chemical composition ( 4 ) is integrated into the packaging ( 2 ) in such a manner that the chemical composition is not directly in connection with the food ( 3 ), but is accessible to the breakdown product of the food ( 3 ).
6. The food packaging arrangement according to claim 1 , characterized in that the chemical composition ( 4 ) is present in bound form on a support ( 7 ).
7. The food packaging arrangement according to claim 6 , characterized in that the support ( 7 ) is a semipermeable membrane that is permeable to the breakdown product of the food ( 3 ) in question.
