Abstract
Abstract Disclosed are simulated, puffed dried fruit pieces and methods for their preparation. The dried fruit pieces are useful for incorporation into ready-to-eat cereals of low water activity, e.g., A w of 0.1 to 0.3, such as puffed cereals. The dried fruit pieces are characterized by a low density ranging from 0.15 to 0.40 g./cc. due in part to a hollow center and thus do not settle during distribution and storage, and do not sink in milk. The dried fruit pieces are prepared by drying in prescribed manner pieces comprising encapsulated solutions containing hydrophilic colloids set with gelling agents.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
143 words
A method for preparing a dried, simulated hollow fruit product comprising in sequence the steps of: (A) contacting a solution with a bath to form encapsulated pieces, said solution comprising (1) about 40 to 70% moisture (2) about 1 to 6% sweeteners, and (3) about 0.5 to 2.0% hydrophilic colloid (wet basis) said bath containing a gel setting agent capable of causing the hydrophilic colloid to set up an encasement around said pieces; immediately thereafter, (B) first drying the pieces with forced convection drying with hot air at about 220° to 280° F. to a moisture content of less than about 20%, to form hollow cored pieces; and (C) finish drying the hollow cored fruit pieces to a moisture content of about 5 to 10% to form a hollow centered dried simulated fruit piece having a density of about 0.15 to 0.40 g./cc.
Claim 2
Independent Claim
143 words
A method for preparing a dried, simulated hollow fruit product comprising in sequence the steps of: (A) contacting a solution with a bath to form encapsulated pieces, said solution comprising (1) about 40 to 70% moisture (2) about 1 to 6% sweeteners, and (3) about 0.5 to 2.0% hydrophilic colloid (wet basis) said bath containing a gel setting agent capable of causing the hydrophilic colloid to set up an encasement around said pieces; immediately thereafter, (B) first drying the pieces with forced convection drying with hot air at about 220° to 280° F. to a moisture content of less than about 20%, to form hollow cored pieces; and (C) finish drying the hollow cored fruit pieces to a moisture content of about 5 to 10% to form a hollow centered dried simulated fruit piece having a density of about 0.15 to 0.40 g./cc.
Claim 3
Dependent Claim
40 words
