Abstract: Potato strips, which are cut from raw potatoes and blanched, are contacted with an aqueous solution containing one or more hydrocolloids to deposit a hydrocolloid layer on the surface of the strips. The potato strips preferably are partially dried before being contacted with an aqueous starch-based slurry to provide a starch-based batter coating over the hydrocolloid layer. The potato strips having the dual coating of a hydrocolloid and a batter, are then parfried and frozen. When reconstituted by finish frying in hot oil, the resulting french fries have an extended holding quality, remaining crisp and tender for prolonged periods after finish frying.

Abstract: A process for preparing frozen potato strips which remain crisp for an extended period of time after finish frying. Potatoes which have been cut into strips and blanched are contacted with an aqueous solution having a pH in the range of about 5.5 to 8.5 which contains a hydrolyzed starch product, such as dextrin or maltodextrin. The pH of the aqueous solution is maintained within the desired range by the addition thereto of a basic alkali salt. A conventional chelating agent and reducing sugar may also be included in the aqueous solution. After contact with the aqueous solution, such as by immersion, spraying, and the like, the potato strips may be partially dried in hot air and are then frozen. The frozen potato strips are prepared for consumption by finish frying under suitable time-temperature conditions. Contacting the blanched potato strips with an aqueous solution containing a hydrolyzed starch product and having a pH in the range of 5.5-8.

Abstract: An improved rotary cutting apparatus is provided for cutting vegetables, particularly such as potatoes, into a distribution of strip sizes not exceeding a predetermined length limit. The apparatus comprises a conventional rotary impeller having peripheral blades for carrying potatoes into cutting relation with a slicing knife on an impeller housing for dividing the potatoes into slices followed by subsequent cutting into strips by strips knives on an adjacent cross-cut spindle. The impeller further includes an axially centered divider ring defining a pair of annular chambers for potato passage outwardly to the slicing knife, wherein longer potatoes are required to orient with their longitudinal axes extending generally radially with respect to the impeller, and generally perpendicular to the slicing knife, to limit the maximum length of the cut slices and the resultant cut strips.

Abstract: A process is provided for producing parfried and frozen potato product strips including but not limited to French fries, wherein the potato strips are adapted for reconstitution, immediately prior to consumption, in a microwave oven, conventional oven, convection oven, or finish fryer with highly desirable taste, color, and textural characteristics. The process comprises parfrying the potato strips under controlled time and temperature conditions to include two parfrying steps with an intermediate cooling step wherein the strips preferably are frozen to reduce the moisture content of the strips in accordance with a predetermined relationship of strip size, strip surface area, and moisture loss during processing.

Abstract: The invention provides for addition of a process oil in a liquid state, such as a vegetable oil, an animal fat or blend thereof to potato dough ingredients to enhance tenderness and crispness in the finished formed potato product and to reduce occurrences of "feathering" and "overmixing" of the dough during processing. Accordingly, a liquid oil addition of from about 0.12 weight percent to less than about 2.0 weight percent to the potato dough ingredients is presently preferred as producing the most desirable end product with respect to crispness, flavor, and interior and exterior characteristics. In one embodied form of the invention, the process oil may be added by incorporation of finely chopped, par-fried, frozen, potato eliminations into the potato dough. If eliminations are incorporated, a maximum of about 4.0 weight percent process oil in the potato dough can be utilized in accordance with the present invention.

Abstract: A frozen french fried potato product for heating in a toaster or oven, is provided. The product is made from a cohesive dough which is prepared by admixing cooked potatoes with additives comprising water, a binding agent, cellulose, and dehydrated potato flakes or granules. The dough is extruded into said product which is fried in cooking oil and frozen.
