Method of producing a darkened freeze-dried coffee |
摘要 |
The color of freeze dried coffee can be darkened by carefully controlling the pressure in the drying chamber during the first 1 to 5 hours of the drying cycle. By maintaining the pressure at between 350 to 650 microns of mercury for the specified time, a surface darkening is achieved without allowing the product to actually melt or puff. Thus, a high quality freeze dried coffee is obtained with a more desirable appearance.
