Question regarding food additives: potassium ferrocyanide, with a detected content exceeding 100
Thread Content
The total content of potassium ferrocyanide in the raw material is always over 100, but when using analytically pure potassium ferrocyanide, the value is within the normal range. I’m seeking an explanation for this; in my opinion, it is caused by some of the crystalline water in the raw material, potassium ferrocyanide, being lost.
Your question is not clearly stated. Analyzing potassium ferrocyanide involves identifying what substance, element, or group is the object of analysis, and then expressing it in terms of potassium ferrocyanide For the analysis of substances containing crystalline water, it is necessary to accurately determine the quantity and form of the sample under stable conditions. When there is a slight loss of crystalline water, the results obtained will definitely be inaccurate.
