Studies of Oxygen and Oxygen Exchange in Fruits Using Gas in Scattering Media Absorption Spectroscopy
The concentration of the biologically active molecular oxygen gas is of crucial importance for fruits, not only in the maturation and ripening processes, but also in the metabolic respiration. We have studied oxygen content and oxygen exchange in fruits non-invasively by using Gas in Scattering Media Absorption Spectroscopy (GASMAS). By studying how the GAS-MAS oxygen signal changes during the ripening process of different kinds of tropical fruits nectarine (NE), mango (MG), papaya (PA), and guava (GU), the state of ripeness of fruits can be assessed. Oxygen diffusion measurements on peeled and unpeeled apples are also performed, and the results show that the skin strongly influences the gas exchange with the environment.
