Abstract:

In the disclosed treatment of foods or foodstuffs (particularly liquid and semi-liquid or semi-solid foods and solid foods such as meats and stews), the food or foodstuff is subjected to very high hydrostatic pressures in the presence of a saccharide ester (e. g. sucrose mono-, di-, and/or tri-C. sub. 8 -C. sub. 24 -fatty acid esters) at temperatures above 35. degree. C. but preferably below 60. degree. C. for a relatively short period of time (less than 60 minutes). This treatment is effective in essentially eliminating sporeforming organisms, whether in the form of spores or in the vegetative state.
