Abstract
This invention relates to a process for manufacturing potato chips using chemically treated frozen potatoes which exhibit the good quality of promptly harvested potatoes. Potato slices are dipped in a heated solution containing ultraphosphate. Subsequently, the dipped slices are frozen and stored. Eventually, the frozen slices are thawed and fried for consumption.
Claims2
A process for manufacturing potato chips using chemically treated frozen potatoes which consists essentially of:
- (a) washing, peeling and slicing potatoes to obtain potato slices;
- (b) preparing a heated dipping solution having a concentration of 0.2-1.0% by weight of ultraphosphate, wherein the dipping solution is heated to a temperature of 40.degree.-50.degree. C.;
- (c) dipping potato slices in the heated dipping solution for 3-5 minutes;
- (d) rapidly freezing the dipping potato slices a -40.degree. to -60.degree. C. for 5 to 30 minutes;
- (e) storing the frozen potato slices at about -20.degree. C.;
- (f) thawing the frozen potato slices at about 30.degree.-80.degree. C;
- and
- (g) frying the thawed potato slices in vegetable oil.
