PotassiuM iodide starch pa - Names and Identifiers
PotassiuM iodide starch pa - Introduction
PotassiuM iodide starch pa is a chemical reagent used to detect the content of starch in a substance. It consists of starch and potassium iodide.
PotassiuM iodide starch pa has the following properties:
1. The appearance of white or light yellow paper or strip.
2. When the test paper is in contact with a substance containing starch, the test paper will turn blue or purple, the darker the color, the higher the starch content.
3. In the absence of starch on the material to maintain the original color test paper.
The main use of PotassiuM iodide starch pa is to quickly detect the starch content in food and biological samples. It is often used to detect the incorporation of starch in food (as an inexpensive filler) and to qualitatively detect the amount of starch in organisms or tissues in biological experiments.
The method of preparing PotassiuM iodide starch pa is relatively simple. Dissolve a small amount of starch and an appropriate amount of potassium iodide in a sufficient amount of water, then soak the filter paper or paper strip in the solution and dry to obtain the test paper.
Note the following safety information when using PotassiuM iodide starchpa:
1. Potassium iodide solution and iodine is toxic, should avoid direct contact with the skin or inhalation.
2. When using the test paper, pay attention to avoid eating or contact with eyes and oral mucosa.
3. Waste test paper should be properly handled to avoid environmental pollution.
4. Before using the test paper, it is best to read and follow the relevant safety instructions.
