A method for altering a coffee source component profile of an aged coffee source to mimic a target coffee component profile of a non-aged coffee source, wherein the aged coffee source and the non-aged coffee each comprise multiple taste contributing acids. In a switching system, a Master Controller is provided for maintaining the database of the system, and for receiving call processing control messages. In response to the first distance being less than a threshold distance, the media is credited as exposed to the first panelist. The squeegee implement further includes a guiding structure in fluid communication with both the wiping blade and the absorbing component for guiding the liquid from the wiping blade to the absorbing component. Therefore, since the display device does not require a backlight unit and a driving circuit unit for driving the backlight unit, the display device has reduced power consumption, a slim and lightweight profile, and a simple structure. The compositions and isolated components obtained by the methods of the invention can be used in pharmaceutical, medical, nutritional, cosmetic or health applications.
