Determination of the respiration index and of the modified atmosphere inside the packaging of minimally processed products.

Résumé

In order to study the physiological influence of the different processes involved in obtaining minimally processed products, the authors studied the respiratory intensity of pomegranate seeds, sliced orange and both together. The storage temperature was 4 °C. The pomegranate variety was Mollar (Punica granatum L.) and the orange Washington Navel (Citrus sinensis, L., Osbeck). The gas composition inside the packaging was determined by extracting a volume of gas through a silicone septum attached to the plastic film. Changes in the concentration of O2 and CO2 were determined by injecting 5 ml of the modified atmosphere into a Toray LC700C O2 analyzer and a Toray PG-100 CO2 analyzer (Toray Engineering Co., Ltd). Variations over time in the concentrations of these two gases surrounding the products, which were wrapped in two films, one of high and the other of low permeability, were recorded.
