Abstract
Sliced potato products are prepared for refrigerated storage and distribution while retaining the characteristics of wholesome, freshly sliced potatoes for a minimum of 45 days. The potatoes may be peeled, or unpeeled, and cut into any sliced configuration, such as French fries, crinkle cuts, or homefries. The potato pieces are then washed, dewatered, and sterilized in a hot oil blanch. The cut potatoes are then mechanically chilled and packaged in an inert atmosphere which utilizes CO.sub.2 as a component. The packaged potatoes are stored and distributed under refrigeration until ready for use.

A method of preparing the packaging cut, washed, and dewatered potatoes consisting of the steps of:
- blanching and sterilizing the potatoes in hot oil at about 360.degree. F. for about 1.5 to 3 minutes;
- chilling the potatoes;
- and then
- packaging the potatoes in a package having an inert gas atmosphere containing CO.sub.2 thereby reducing bacterial growth on the potato surfaces by the formation of carbonic acid on the potato surfaces.
A method for preparing and packaging sliced and washed potatoes consisting of the steps of:
- blanching and sterilizing the potatoes in about 360.degree. F. (182.degree. C.) oil for about 1.5 to 3 minutes;
- draining excess oil;
- chilling the potatoes;
- evacuating a package;
- inserting the potatoes in the package;
- purging the package with a gas mixture of CO.sub.2 and N.sub.2 ;
- sealing the package;
- and then
- storing the package in a cool temperature until ready for cooking.
