This invention relates to non-brittle dried fruits and vegetables, especially non-brittle freeze-dried fruits and vegetables, and methods for preparing such fruits and vegetables. More specifically, this invention relates to non-brittle dried fruits and vegetables prepared by applying a surface coating of an aqueous solution of a polyhydric alcohol (preferably glycerol) prior to drying. Application of the aqueous solution of the polyhydric alcohol prior to drying appears to allow sufficient migration of polyhydric alcohol into the cellular structures, thereby plasticizing the cellular structures and minimizing damage to the cellular structures of the fruits and vegetables during and after drying and post-drying activities. The resulting plasticized product is rendered non-brittle as indicated by a drastic reduction of fines and/or broken pieces after drying and/or packaging, shipping, and storage as compared to conventionally dried fruits and vegetables.
A method for producing non-brittle dried fruits or vegetables, said method comprising (1) applying an aqueous solution containing a polyhydric alcohol to the exterior surface of the fruits or vegetables to be dried;
A method for producing non-brittle dried fruits or vegetables, said method comprising (1) applying an aqueous solution containing about 1 to about 40 percent of a polyhydric alcohol to the exterior surface of the fruits or vegetables to be dried;
Non-brittle dried fruits or vegetables comprising fruits or vegetables which have been freeze dried in the presence of an aqueous solution containing about 1 to about 40 percent of a polyhydric alcohol to form the non-brittle dried fruits or vegetables, wherein the fruits or vegetables are contacted with the aqueous solution and maintained in the aqueous solution for about 10 seconds to about 2 minutes at a temperature below about 20° C. prior to being freeze-dried, and wherein the non-brittle fruits or vegetables are less susceptible to breakage or fracture as compared to comparable fruits or vegetables freeze dried in a comparable manner without presence of the aqueous solution containing the polyhydric alcohol.
