Title
(EN) ATMOSPHERE CONDITIONING AGENT
(FR) AGENT DE CONDITIONNEMENT DE MILIEU
Abstract
(EN)
An atmosphere conditioning agent containing a deoxygenating and carbon dioxide generating agent such as ascorbic acid, aiming at improving the adaptability to filling in packaging material, shortening the time required for realizing an anaerobic atmosphere, and regulating the concentration of oxygen and carbon dioxide in an anaerobic atmosphere being conditioned to be each in a desired range. The conditioning agent comprises a carbon dioxide generating agent, a ferrous compound, a pH modifier and water dispersed in a dispersant comprising silicon dioxide and/or calcium silicate, crystalline cellulose, and optionally active carbon. Preferably, according to the gas composition of a desired anaerobic atmosphere, ascorbic acid or calcium carbonate is used as the carbon dioxide generating agent, while calcium hydroxide and/or sodium carbonate is used as the pH modifier.
(FR)
Agent de conditionnement de milieu, contenant un agent de désoxygénation produisant du dioxyde de carbone, tel que l'acide ascorbique, destiné à améliorer le remplissage de matériaux d'emballage, par le raccourcissement du temps nécessaire pour obtenir un milieu anaérobie, et par la régulation de la concentration de l'oxygène et du dioxyde de carbone dans une atmosphère anaérobie que l'on désire conditionner, de manière que les valeurs de concentration se situent chacune dans une plage désirée. L'agent de conditionnement comprend un agent générateur de dioxyde de carbone, un composé ferreux, un modificateur de pH et de l'eau dispersée dans un dispersant comprenant du dioxyde de silicium et/ou du silicate de calcium, de la cellulose cristalline, et éventuellement du charbon actif. De préférence, en fonction de la composition gazeuse du milieu anaérobie désiré, on utilise de l'acide ascorbique ou du carbonate de calcium en tant qu'agent générateur de dioxyde de carbone, et de l'hydroxyde de calcium et/ou du carbonate de sodium en tant que modificateur de pH.
