Abstract

Abstract Potatoes are converted into convenience food products, using techniques which provide advantages over customary operations. Example: Potatoes are cooked and mashed. The mash is shaped into strips which are then treated with hot air at about 200* to 300*F. for about 1 to 5 minutes prior to steaming them for about one quarter to 1 minute and again applying hot air at about 200* to 300*F until the weight loss thereof is about 30 to 35 percent to case-harden their surfaces. The resulting intermediates may be fried directly and/or held in frozen or cold storage for future use. On frying, they yield products which have the taste, appearance, color, and texture of high-quality conventional French fries plus added advantages of higher solids content, lower fat content, and no tendency to get limp.
