Coffee treatment process and product.

摘要

The preparation of a substantially homogeneous freeze dried coffee product is effected by i) mixing a coffee extract at a temperature in the range of from 0 DEG to 20 DEG C with from 10 to 60% by weight of roast and ground coffee particles based on the weight of the two coffee constituents, the said particles having a particle size such that 98% by weight of the ground coffee passes a 75 micron mesh; ii) subjecting the mixture from step (i) to homogenization; iii) passing the homogenized mixture from step (ii) to a mixing tank and adding thereto at least an equivalent weight of coffee extract at a temperature in the range of from minus 5 to 30 DEG C and from 20 to 40% by weight of frozen coffee fines based on the weight of the homogenized extract and the coffee extract; iv) freezing the mixture from step (iii); v) grinding the frozen coffee product; vi) screening the ground frozen coffee product from step (v); and vii) subjecting frozen particles of an appropriate size to freeze drying. i
