| Abstract: | By using mannose as the standard and DNS as colour developing reagent,the author indirectly determinated the content of mannan in defatted coffee grounds by spectrophotometry. The Results shewed that there is the highest absorbance at 492 nm,and the standard recovery rates high,and the relative error small,and the recurrences good,and this method is simple and suitable for all kinds of defatted coffee grounds. |
