用三刺激色度仪测定面粉的白度

Measuring Flour Whiteness by A Tristimulus Colorimeter

应用三刺激色度仪测定面粉的白度的结果表明,它对面粉中加入低等级面粉和麸皮有较高的分辨能力,而且面粉的水分含量对面粉的三刺激值没有明显的影响。

Initial investigations suggested that it is possible and convenient to measure flour whiteness by a tristimulus colorimeter. The results of this study show that the tris-timulus instrument is sensitive to addition of lower grade flours and bran to a base flour and the moisture content of flour dose not significantly affect the tristimulus measure-ments.
