Appendix A

Testing method A.1 General provisions In addition to the provisions of this standard, the purity of the reagents used are analytical pure, the standard titration solution used, the standard solution for the determination of impurities, preparation And products should be prepared according to GB/T 601, GB/T 602, GB/T 603, test water should be consistent with GB/T 6682 in the three water regulations set. The solution used in the test refers to the aqueous solution when it is not specified in the formulation of the solvent. A.2 Identification test A.2.1 Solubility Weigh 2g sample, add to 50mL of water, can form a granular, hard, slightly milky white gel, the elix is acidic, insoluble In ethanol. A.2.2 Swelling in ethanol solution The sample may swell in 60% ethanol solution. A.2.3 Color response Weigh 0.2g sample, add 20mL of water, boil to form mucus. Add 5mL hydrochloric acid, the mixture and then boil for 5min. should Showing lasting red or pink. Weigh 0.5g sample, mixed with 2mL 5mol/L sodium hydroxide solution, slowly heating, should be brown. A.2.4 Sedimentation test Weigh 1g sample, add to 80mL water, mix shaking 24h, the formation of mucus. Remove 4mL mucus, add 0.5mL hydrochloric acid, Boil, then add 1mL 5mol/L sodium hydroxide solution, filter. In the filtrate by adding 3mL Felix solution, heating, should be generated red precipitation. Determination of acid - insoluble ash A.3.1 Reagents and materials Hydrochloric acid solution. 1 9. A.3.2 Analysis steps A 25 mL hydrochloric acid solution was taken and added to the ash obtained in the determination of total ash and boiled for 5 min. Use a filter crucible or ashless filter paper Filtered, washed with hot water several times, at 675 ℃ ± 25 ℃ to burn to constant weight. A.3.3 Calculation of results Acid-insoluble ash mass fraction w1, calculated according to formula (A.1). w1 = m1 m0 × 100% (A.1) Where. m1 - the mass of the residue after ignition, in grams (g); m0 --- the quality of the sample, in grams (g). The results of the test are based on the arithmetic mean of the parallel measurement results. A.4 Determination of starch or dextrin A.4.1 Reagents and materials Iodine solution. Weigh iodine 14.0g, dissolved in potassium iodide containing 36.0g in 100mL aqueous solution, add 3 drops of hydrochloric acid, diluted with water to 1000mL. A.4.2 Analysis steps A 10 mg/mL sample solution was prepared. Take appropriate sample solution, boil and cool, add a few drops of iodine solution, no blue or red out Now, that is through the test. ......
