Method for preparing dehydrated food products
First Claim
1. A method for drying a material to form a dehydrated product, comprising:
- (a) providing a wet mash comprising the material to be dried; and
(b) drying the wet mash wherein drying the wet mash comprises the steps of;
(i) providing a first energy source selected from the group consisting of conductive heat sources, convective heat sources, infrared energy sources, and combinations thereof;
(ii) providing a second energy source comprising a source of infrared energy;
(iii) forming a layer of the wet mash, the mash layer having a first surface and an oppositely facing second surface;
(iv) heating the first surface of the mash layer with the first energy source; and
(v) heating the second surface of the mash layer with the second energy source;
wherein the mash is dried to a moisture content of less than about 50% by weight prior to heating the second surface of the mash layer;
and wherein at least a portion of the steps of heating the first and second surfaces of the mash layer are carried out simultaneously.

Abstract
A method for preparing dehydrated fruits, vegetables and tubers, particularly potato products. The steps of the method include: boiling the whole raw edible product or slices or pieces of the raw edible product for a time sufficient to partially cook the starch and soften the tissue of the edible product; comminuting the cooked product; and drying the comminuted product. The raw edible product is preferably unpeeled or partially peeled.
The resulting dehydrated product: (1) retains more Vitamin C; (2) has a lighter color; (3) has a higher percent of free amylose; (4) has fewer broken cells; and (5) has fewer degradation products than a corresponding product produced by conventional methods.
