A method of processing potatoes or vegetables to dehydrated hash browns or other forms is disclosed where cooked and cooled potato slices are subjected to a second cooking time to improve flavor, texture and composition. The potato slices are further cooled to a chilled temperature which modifies the starch content of the potato so that the potato can be easily processed to smaller sizes, shapes or dimensions. When processed to a smaller size, shape or dimension, the potato material is contacted with a lubricating substance devoid of water which reduces or prevents the potato pieces from sticking together and improves the composition of the dehydrated potato pieces. The process of the present invention improves the flavor, texture and composition of the potatoes, both during the processing steps and at later rehydration. The process of the present invention also merely modifies the starch content of the potatoes without having to remove the starch and/or add the starch back in at a later time. As a result, product yields are increased.

Method for preparing rehydratable vegetable pieces

A process for making dehydrated potato products from potato flakes so that they can be sulfite-free by mixing the potato flakes with a sufficient amount of water to increase their moisture content to a predetermined level, lowering the temperature of the moistened potato flakes to a temperature and for a period of time sufficient for retrogradation of free soluble starch contained in the potato flakes, reducing the size of the potato flakes in a manner to minimize breakage of potato cell walls, and drying the resulting potato product. The dehydrated potato product can be reconstituted without using a boiling liquid to make a dough for french fries or to make a mashed potato product.

Process for making dehydrated potato products

Process for making a reconstitutable dehydrated, cooked potato piece or strip. Raw potatoes are cooked and a dough of separated potato cells is formed therefrom. A small quantity of the cells are ruptured to release their starch contents. The released starch alone or in combination with additional raw starch which is gelatinized after mixing with the dough are used to give the dough an adhesive character which will permit the eventually dried potato pieces to be reconstituted in water without loss of piece identity. After rupture of the potato cells the dough is maintained in a heated condition until formed into strips or pieces of the desired size after which they are dried. An alternative process employs raw starch as the principle means for obtaining the desired adhesive character in the dried potato pieces. In the alternative process the dough is processed and formed into the desired pieces or strips without heating and thereafter the raw starch is gelatinized by application of heat. The product is thereafter dried.

Dehydrated potato processes

An agglomerate of dehydrated potato particles containing a binder, the agglomerate having a bulk density in the range of 0.25-0.50 grams per milliliter a bulk porosity in the range of 0.6-0.9 and an initial moisture absorption rate during reconstitution at 130.degree.F of 0.20 to 0.35 grams of water per gram of product per second and being reconstitutable without agitation to form a substantially homogenous dough even when disposed as a consolidated mass. By proper distribution of the binder among the particles, the reconstituted potato dough exhibits uniform cohesive characteristics that allow for ready division into shapes suitable for french-frying.

A potato dough is prepared so that it is 23 to 40% solids including cooked intact potato cells, binder and raw starch, the remainder of the dough being moisture. The dough is divided into slabs and cut into strips of normal French fry potato size. The strips are then parfried in deep fat to a moisture content in the range of 40-65% to gelatinize the starch and form a matrix surrounding the intact potato cells throughout the piece, which matrix gels upon cooling, is not thereafter disturbed and makes the product freeze-thaw stable. The product is then frozen and stored. Without loss of piece integrity the product can be finish fried directly, or even after prolonged thawing, by deep fat frying or oven heating to form a crisp French fry.
