For the storage of foodstuffs which are susceptible to oxidative degradation it is proposed to use powdered metal - and especially aluminium - in wet- corrosion compositions using strong corrosion agents, and specifically materials (such as strong acids and strong alkalis) that will reduce the pH to well below 4 or increase it to well above 9. More particularly, it is proposed that the metal and a large-surface-area, reaction-site material be utilised in a very finely powdered form, and especially one in which a significant proportion of the particles are deformed, possibly with fracturing. The compositions can be dispersed within a water- and oxygen-permeable sheet that can be disposed in actual, direct contact with the oxygen-sensitive substance to be protected.

Relativement au stockage de produits alimentaires susceptibles de se dégrader en présence d'oxygène, on propose d'utiliser un métal pulvérulent, spécialement de l'aluminium, dans des compositions à corrosion par voie humide utilisant des agents fortement corrosifs (notamment des produits tels que des acides et des bases forts) portant le pH très au-dessous de 4 ou très au-dessus de 9. On propose plus particulièrement que le métal et le matériau à forte aire superficielle de contact constituant le site de réaction se présentent sous forme de poudre très fine, notamment de poudre dont une importante partie des particules sont déformées et possiblement fracturées. Ces compositions peuvent être dispersées dans des feuilles perméables à l'eau et à l'oxygène disposées en contact direct avec le produit à protéger altérable par l'oxygène.
