Zusammenfassung:	A process for the treatment of vegetables prior to their presentation for sale comprising subjecting them, after cleaning and washing, to the following three successive stages of treatment, namely, an anti-oxidation treatment carried out in an aqueous bath of sodium metabisulphite at a temperature between 80 and 90 DEG C and for a period of 6 to 15 minutes, vacuum packaging in packs made from a plastics material at a temperature above 40 DEG C, and pasteurisation for a period of between 5 and 30 minutes at a temperature between 80 and 85 DEG C, the transfers from one stage to the next being effected without allowing the temperature to fall below 40 DEG C. The transfer of the vegetables from the anti-oxidation treatment stage to the vacuum packaging stage is preferably effected within 4 to 5 minutes, and the process is exemplified in relation to potatoes of the small "BINTJE" variety.
