(3) drug reagents: 1.00 mol/L sodium hydroxide solution of 0.09 M sodium hydroxide solution: take 90 ml solution above, distilled water diluted to 1000 ml has made good iodine solution 】 : iodine (analysis) of 2.00 g and 20.00 g of potassium iodide (analysis) mix, distilled water dissolves the capacity to 1000 ml has made good 】 【 1.00 mol/L acetic acid solution: measuring 57.8 ml ice acetic acid (analysis), distilled water diluted to 1000 ml 95% ethanol has made good 】 【 (analysis).
4. Test method and steps: sample weighing → dispersion → preparation of chrominant → colorimetry → calculation.1.
2. Scattered: 1.0 ml anhydrous ethanol, rocking scatter wet ⇒ plus 9 ml 1.00 mol/L sodium hydroxide solution, rotary volumetric flask flushing of the lye lands on the sample of the bottle wall ⇒ in boiling water for 10 minutes, after cooling constant volume.
3. Preparation of color liquid: 0.09 M sodium hydroxide solution (blank), concentration of four types of sample, sample liquid (the second repeat 5 ml) respectively in 50 ml volumetric flask ⇒ around 30 ml distilled water ⇒ ⇒ 1.0 ml 1.00 M acetic acid solution with 0.2% iodine solution 1 ml, timing immediately, fully shake, constant volume.
4. Colorimetry: let stand for 20 minutes and determine the absorbance at 620nm.
5. Automatic calculation of amylose content
