This document specifies a method for the determination of the loss in mass of solution by drying in the vacuum oven. The determination of the loss in mass (moisture content) in accordance with this standard can be applied to powdered decaffinated and regular coffee extracts. Coffee extracts according to this standard are spray-dried, agglomerated and freeze-dried coffee extracts. The method is not suitable for liquid or pasty coffee extracts. This document (DIN 10764-2) has been prepared by the Food and Agricultural Products Standards Committee (NAL) at Working Committee NA 057-05-09 AA "Kaffee" ("Coffee") and tested in an extensive ring test.
