- Abstract
- Abstract Food is frequently packed in a controlled environment
of gas, in order to extend shelf life. It is of great
importance to be able to monitor the status of the packed
food to ensure quality. We demonstrate a technique to monitor
the gas inside packages non-intrusively by using a laser
spectroscopicmethod in scattering solid materials. The technique
named GASMAS (GAs in Scattering Media Absorption
Spectroscopy) is based on tunable diode laser absorption
spectroscopy and relies on the fact that free gas inside
solid materials absorbs much sharper spectrally than
the bulk material. Results from time dependent measurements
of molecular... (More) - Abstract Food is frequently packed in a controlled environment

of molecular oxygen and water vapour in packages
of minced meat, bake-off bread, and the headspace of a milk
carton are presented. We show that the technique allows gas
measurements inside the food through the package, and assessment
of the integrity of the package. (Less)
