<p>AGGREGATED MIXED-MOISTURE FLAKED COFFEE OF HIGH AROMA Caren A. Klien and Donald R. Gieseker Aggregated coffee flake particles comprise a plurality of compressed coffee flakes bonded together wherein at least one of which is a low-moisture flake (1% to 3.5% by weight) and at least one of which is a high-moisture flake (4.5% to 7% by weight) are disclosed. The composite flake particles range in thickness from 9 to 16 mils. The flaked coffees provide improved extractability of the water-soluble flavor constituents, exhibit high initial aroma levels, and exhibit high bed permeability. Also disclosed is a process for preparing aggregated mixed-moisture flaked coffee. The process comprises: (1) separately cold-grinding dual streams of roast coffee, relatively high-moisture and low-moisture, respectively; (2) combining of the two ground coffee streams to provide a roll mill feed having a specified particle size distribution and average moisture content, and (3) passing the coffee feed through a roll mill under specific conditions, and (4) screening the roll-milled, aggregated flaked coffee to produce a product such that no more than 60% by weight passes through a 30-mesh U.S. Standard screen.</p> |
