Abstract

The invention provides rapid iodized salt detection liquid. The rapid iodized salt detection liquid is prepared from the following raw materials: a reducing agent, namely arsenious acid with the concentration of 0.005-0.010g / mL, an indicator, namely amylose with the concentration of 0.002-0.006g / mL, a preservative, namely zinc chloride with the concentration of 0.0005-0.0015g / mL and sodium hydroxide with the concentration of 0.0100-0.0150g / mL; the pH of the detection liquid is 1-1.5. The rapid iodized salt detection liquid provided by the invention is suitable for the detection of iodized salt, the iodine preparation of which is potassium iodate, and iodized salt, the iodine preparation of which is potassium iodide. The rapid iodized salt detection liquid has the advantages that the reducing agent is the arsenious acid, so that the detection speed is relatively rapid; the appropriate pH and the purified amylose are used for preparation, so that the sensitivity and stability of reaction colors are ensured; the zinc chloride is used as the preservative, so that after the rapid iodized salt detection liquid is stored for a long term, the color gradation of the rapid iodized salt detection liquid is still obvious during detection.
