  • Patent number: 5783246
    Abstract: Included is the preparation of particulate coffee products with improved particle packing characteristics. Fine coffee particles having particle diameters of less than about 600 micrometers are compacted to a bulk density of from about 0.40 to about 0.70 gm/cc. The resulting coffee products have the isodensity and isobrew solid profiles as shown in FIGS. 1 and 2, respectively, where the bulk density and brew solid values for any ternary particle mixture represented on the graph increases with increased coffee fine fractions therein. The process can also be used to control or increase the bulk density of particulate coffee products thereby eliminating or reducing the need to rely upon roasting means to control bulk density. The compaction operation changes the particle morphology without rupturing the cell walls of the coffee.

  • Patent number: 5490999
    Abstract: A process for preparing a high protein or low fat nut spread having desirable fluidity, texture and flavor. The process comprises as a first step depositing a nut paste in a mixing tank. Next, the solid ingredients are mixed sequentially with the paste with the proteins being added last. The Casson plastic viscosity of the mixture is adjusted to about 30 poise or less. This mixture is then pumped through a homogenizer and a colloid mill or series of colloid mills. Nut spreads having a bimodal particle size distribution such that at least 50% of the solids in the nut spread have a particle size of less than 18 microns and 90% of the solids in the nut spread have a particle size of less than 60 microns, and further having a Casson plastic viscosity of from about 8 to about 17 poise and a yield value of less than about 300 dynes per square centimeter are produced according to this process.

  • Patent number: 5433970
    Abstract: A process for preparing a high protein or low fat nut spread having desirable fluidity, texture and flavor. The process comprises as a first step depositing a nut paste in a mixing tank. Next, the solid ingredients which are to be present in the final product spread are mixed into the tank containing the peanut paste. The Casson plastic viscosity of the mixture is adjusted to about 30 poise or less. This mixture is then pumped through a homogenizer and a colloid mill or series of colloid mills. Nut spreads having a bimodal particle size distribution such that at least 50% of the solids in the nut spread have a particle size of less than 18 microns and 90% of the solids in the nut spread have a particle size of less than 60 microns, and further having a Casson plastic viscosity of from about 8 to about 17 poise and a yield value of less than about 300 dynes per square centimeter are produced according to this process.

  • Patent number: 5230919
    Abstract: The invention is a reduced past nut or oilseed butter composition made from roasted nuts which contains: (a) from about 40% to about 67% nut solids, between 65% and 80% of said solids having a particle size less than 18 microns and a SPAN of greater than 2.5 and not more than 5.0; (b) from about 33% to about 45% oil; (c) from 0% to about 4% stabilizer; (d) from 0% to about 40% bulking agent; (e) from 0% to about 8% flavorant; and (f) from 0% to about 3% emulsifier; where the product has a Casson plastic viscosity of between 1 and 15 poise and a yield value below 300 dynes per square centimeter. The invention also relates to a reduced fat or full compositions of the general type described above which is whipped to contain dispersed gas bubbles, where at least 90% of the bubbles have a diameter less than 150 microns. Processes for making these compositions are also described.
