Jiuhua Food Safety Soy Sauce Total Acid Testing Reagent Supply, High Cost-Effectiveness

Soy sauce total acid detection reagent
. Measured by the National Standards Center and strictly configured in accordance with the national standard B/./-. The soy sauce total acid detection reagent is used to detect the total acid content in soy sauce. Through the amount of reagent added, it can be qualitatively judged whether the total acid content in soy sauce is qualified. Convenient and safe, simple operation, accurate results and high sensitivity.

. Soy sauce total acid detection reagent
. Used to detect the total acid content in soy sauce. Hygienic standards stipulate that the total acidity of soy sauce should be./. The total acid in soy sauce is titrated with an alkali standard solution. In the presence of an indicator, the end point of the determination is when the sample solution changes from colorless to pink. Based on the number of drops of the alkali standard solution consumed, the total acid content in the sample can be calculated.

.
. Operation method:
.
. Take the sample into the colorimetric tube, add water (distilled water or purified water) to the scale, and cover the plug. Then mix evenly and take it from it. Put it into an Erlenmeyer flask, add water (if the color of the solution is darker, you can increase the amount of water appropriately, but be careful to add the same amount of water when doing blank solution experiments), add a few drops of chromogenic reagent , shake well, and use a dropper bottle to add the total acid and amino acid nitrogen determination solution drop by drop in an upright manner. Shake each drop well. Stop the titration when the solution initially turns pink (yellow with powder). Press each drop. The measuring solution is equivalent to .g of total acid. Calculate the total acid content (if the measuring solution does not turn pink after consuming a drop, it means that the total acid exceeds the standard and should be sent to the laboratory for accurate quantification. The results determined by this method are consistent with the amount specified in the national standard or label When the marked amount differs by only ~ one drop (measurement solution), it should be handled with caution and can be sent to the laboratory for accurate quantification.

. Note:,
. Drinking water cannot be used as a diluent for measurement. It is recommended to use distilled water or purified water.
.
.
. Store in a sealed seal.
