| Powder | Q/371426FY 007 | Take an appropriate amount of sample and place it in a clean and dry container. Observe the color and condition of the sample under appropriate natural light, and check for visible impurities; Take an appropriate amount of sample to smell its taste, put it in your mouth to taste its taste (rinse your mouth with water before tasting the second sample), and make a record. | |

| pH | 5.0-7.0 | Take a proper amount of sample, prepare the solution to be tested with pure water with a dry matter of about 30%, wash the electrode with the sample solution, insert the electrode into the sample solution, adjust the temperature of the pH meter to compensate to 25 ºC, and measure the pH value of the sample solution. Repeat the operation until the pH reading stabilizes for 1 minute, and record the result. | |
| Ash, % | ≤0.1 | Place the crucible on a high-temperature furnace or electric heating plate, with a half lid on the crucible cover, and carefully heat it to completely carbonize the sample without smoke under ventilated conditions. Immediately place the crucible in the high-temperature furnace, raise the temperature to 900 ºC± 25 ºC, and maintain this temperature until all remaining carbon disappears. Generally, ashing can be completed within 1 hour. Cool it to around 200 ºC, take it out, and cool it in a dryer for 30 minutes. If carbon particles are found in the burnt residue before weighing, a small amount of water should be dropped into the sample to moisten it, making the clumps loose. Steam the water dry and burn it again until there are no carbon particles, indicating complete ashing. Only then can it be weighed. Repeated burning until the difference between the two weights does not exceed 0.5mg is considered constant weight. | |
