  • Patent number: 5512308
    Abstract: Disclosed is the preparation of fruit and nut mixes with improved texture stability. Such mixes contain from about 15% to about 60% fruit and from about 40% to about 85% nuts wherein at least about 20% of the nuts are roasted and at least about 20% of the nuts have a crystalline sugar coating. The fruit for use in the mix has an initial water activity of from about 0.35 to about 0.70 and an initial moisture content of from about 7% to about 18% water. The roasted nuts for use in the mix have an initial water activity of from about 0.05 to about 0.40 and an initial moisture content of up to about 3% water. Once the fruit and nuts are combined, they are allowed to equilibrate in a moisture impervious environment to an equilibrium water activity of from about 0.35 to about 0.58 and a percent moisture to equilibrium water activity ratio of the fruit of from about 17:1 to about 32:1.

  • Patent number: 5464642
    Abstract: Disclosed is a process for making from dough a reduced-fat fried snack which has a more expanded, lighter structure than conventional fried snacks. A dough is formed which contains from 50% to 70% flour (preferably potato flour), at least 3% hydrolyzed starches, from 1% to 10% calcium carbonate, and a relatively low level of added water (20% to 40%). The dough is formed into a sheet from which snack pieces are cut and fried. The fried snack pieces contain only 18% to 38% fat. The fried snack pieces are from 1% to 14% larger by volume as compared to conventional fried snack pieces of equal weight.

  • Patent number: 5366748
    Abstract: An improved method for the production of extruded cereal grain-based fried food products having improved qualities is provided. In the improved method, the cereal grain-based food product is formed by extrusion of a cereal grain dough mass containing a gum such as carboxymethyl cellulose and optionally a protein, followed by frying the extruded cereal grain dough to produce a fried cereal grain food product having reduced gumminess or toothpacking and grittiness.
