  • Method of preserving foodstuffs
    Patent number: 4834997
    Abstract: A method of extending the shelf life of foodstuffs comprises the steps of evacuating gas from the foodstuff and treating the foodstuff with carbon dioxide and sulphur dioxide either in admixture or sequentially. The gases are then evacuated from the foodstuff, which is sealed into a container under an inert gas. In cases where the preserved foodstuff is likely to exude moisture during storage, water may be removed from the product. Foodstuffs treatable by the method include fruit such as apples.
