Abstract

1375704 Preserving food F C JOHNSON 8 Feb 1972 [8 Feb 1971] 4205/71 Heading A2D A process for preserving food comprises effecting the absorption of a humectant which is glycerol, propylene glycol, sorbitol or mixtures thereof, and then the partial removal of water from the food to obtain a partially dehydrated product containing an aqueous solution of the above humectant, the amount of water present in the partially dehydrated product being- greater than that at which the food would be preserved by dehydration alone but not greater than 40% by weight for meat and fish, and not greater than 66% by weight for fruit and vegetables, and the amount of humectant being such that the water activity of said aqueous solution is below that at which bacterial and enzymatic activity takes place. For fruit or vegetables, the humectant may be added in the form of a sulphiting solution before the removal of water therefrom. For meat and fish, these may be partially cooked in a humectant-containing liquor prior to the removal of water therefrom. The water may be removed by freeze drying.
