Appendix A

Testing method A.1 General Provisions This standard reagents and water in the absence of other specified requirements, refer to the three water analytical reagent and GB/T 6682 regulations. test In the standard titration solution, impurity measurement standard solution, preparations and products, did not indicate when the other requirements, according to GB/T 601, GB/T 602 and GB/T 603 provisions prepared. Solution was used in the tests did not indicate what is formulated with solvent, it refers to an aqueous solution. A.2 Identification Test A.2.1 solubility Insoluble in water, dilute acid, dilute alkali solution and most organic solvents. A.2.2 Identification A.2.2.1 air nozzle with 38μm sieve 20g sample 5min. Failure to sift greater than 5%, then the sample is dissolved in 270mL 30g Water; otherwise 45g sample was dissolved in 255mL of water. This is the test solution. The sample solution in a high-speed masher (18000r/min to On) mixed 5min. Take 100mL of the mixed solution was transferred to 100mL graduated cylinder and allowed to stand 3h. The surface should be white, impervious Bright, bubble-free upper layer dispersion (keep this dispersion was used to identify test A.2.2.2) appears. A.2.2.2 A.2.2.1 Identification Test taken in the dispersion of the sample solution is added 1mL starch indicator solution in 20mL sample solution (10g/L), add a few drops of iodine standard solution (0.1mol/L), no blue or purple to blue color. A.3 Determination of carbohydrate content (in terms of cellulose, dry basis) of A.3.1 Reagents and materials A.3.1.1 sulfuric acid. A.3.1.2 potassium dichromate solution. 0.5mol/L. Weigh 25g potassium dichromate, dissolved in water 1000mL, shake. A.3.1.3 ferrous ammonium sulfate standard titration solution. c [(NH4) 2Fe (SO4) 2] = 0.1mol/L. A.3.1.4 1,10- phenanthroline - ferrous indicator solution. A.3.2 Analysis step Weigh about 125mg sample accurate to 0.01mg, with about 25mL of water to be transferred to 300mL Erlenmeyer flask. Added 50.0mL Potassium dichromate solution and mixed. Then carefully added 100mL sulfuric acid and heated to boiling. Heat was removed, allowed to stand at room temperature for 15min, to After cooling in a water bath transferred to 250mL volumetric flask, dilute with water to nearly the mark, cooled to 25 ℃, and then diluted with water to volume and mix. take The liquid 50.0mL, add 2 drops to 3 drops of 1,10-phenanthroline - ferrous indicator solution with 0.1mol/L ammonium ferrous sulfate standard titration solution titration, remember The recorded consumption. Blank test at the same time, consumption records 0.1mol/L ammonium ferrous sulfate standard titration solution. A.3.3 Calculation Results Carbohydrates (cellulose meter, dry basis) of the mass fraction w1, according to equation (A.1) Calculated. w1 = (V1-V2) × 338 m × 100% (A.1) Where. V1 --- blank test volume consumed ferrous ammonium sulfate standard titration solution, in milliliters (mL); V2 --- sample consumption volume of ferrous ammonium sulfate standard titration solution, in milliliters (mL); 338 --- conversion factor; M --- the quality of the sample, in milligrams (mg), according to the measured loss on drying value is corrected. The results parallel arithmetic mean of the measurement results shall prevail. A.4 pH measurement Weigh 5g sample, add 40mL water, shaken 20min, centrifugation. Then measured with a pH meter method according to GB/T 9724 provisions pH of the supernatant. A.5 Determination of water-soluble substance A.5.1 Analysis step Weigh 5g samples, accurate to 0.0001g, and 80mL water mix, this is a sample solution. Sample solution was shaken for 10min, the sample The solution was filtered into a filter paper of known weight evaporating dish, the filtrate was evaporated to dryness on a steam bath, and then dried under ± 2 ℃ 1h, cooled at 105 ℃, Weighed. A.5.2 Calculation Results The mass fraction of water-soluble substance w2, according to equation (A.2) Calculated. w2 = m2-m1 m0 × 100% (A.2) Where. After drying --- m2 evaporating dish along with the quality of the dried product, expressed in grams (g); Mass m1 --- evaporating dish in units of grams (g); m0 --- sample mass, in grams (g). ......
