Abstract
A contact-dehydrating sheet suitable for use in the production of dried protein-containing food such as fish and meat and a method for drying the protein-containing food are presented. The contact-dehydrating sheet comprises: (a) a water permeable film, (b) a dehydrating layer consisting essentially of a water absorbing polymer substance dispersed in a hydrophilic adhesive substance, said layer being placed on the surface, opposite to the surface where the protein-containing food to be dried is contacted, of the water-permeable film, and (c) a protective film covering over the dehydrating layer.

A contact-dehydrating sheet for drying protein-containing food comprising:
- (a) a water-permeable film;
- (b) a dehydrating layer consisting essentially of a water absorbing polymer substance dispersed in a hydrophilic adhesive substance selected from the group consisting of hydrophilic polysaccharides and the chemically modified product thereof and synthetic hydrophilic adhesive substances, said layer being placed on the surface, opposite to the surface where the protein-containing food to be dried is contacted, of the water-permeable film;
- and
- (c) a protective film covering over the dehydrating layer.
A method for drying protein-containing food comprising the step of contacting at least a portion of the protein-containing food to be dried with a contact-dehydrating sheet, said sheet comprising (a) a water-permeable film;
- (b) a dehydrating layer consisting essentially of a water absorbing polymer substance dispersed in a hydrophilic adhesive substance selected from the group consisting of hydrophilic polysaccharides and the chemically modified product thereof, and synthetic hydrophilic adhesive substances, said layer being placed on the surface, opposite to the surface where the protein-containing food to be dried is contacted, of the water-permeable film;
- and (c) a protective film covering over the dehydrating layer.
