Beschreibung
Zusammenfassung:	A humidity control device for use in maintaining the desired humidity of a closed environment, e.g., a container, while also decreasing headspace oxygen, the device including a water vapor and oxygen permeable pouch, an aqueous salt solution containing humidity controlling salts in combination with salts of ascorbic acid or isomers thereof. L'invention concerne un dispositif de régulation de l'humidité destiné à être utilisé pour maintenir l'humidité souhaitée dans un environnement fermé, par ex., un contenant, tout en diminuant le taux d'oxygène dans l'espace de tête, ledit dispositif comprenant une poche perméable à la vapeur d'eau et à l'oxygène, une solution saline aqueuse contenant des sels régulant l'humidité en association avec des sels d'acide ascorbique ou des isomères de l'acide ascorbique.
