Abstract
A food objective for extraction and/or squeezing is charged into a colloid mill or a twin-screw extruder; immediately after and/or while milling, a low-temperature solvent (for example, water or milk of from −3 to 50° C.) is added; and after treating the food using the extruder, grounds are removed to produce an extract and/or a squeezed liquid.
Claims3
A process of producing an extract of coffee, which comprises charging roasted coffee beans for extraction in a twin-screw extruder having a narrow gap;
- milling said coffee beans, and immediately after milling, adding a low-temperature solvent from 2-30° C., followed by kneading said milled coffee beans in the solvent to thereby treat the coffee beans to extract useful components into the solvent;
- and optionally removing extraction grounds, wherein said milling and said extracting are carried out in the twin-screw extruder such that said milling and extracting are carried out by said twin-screw extruder.
