Potassium iodide and zinc sulfate are recognized for their nutritional benefits at low concentrations. Blue vitriol, primarily a fungicide, is not commonly used in food production. The discussion highlights the importance of understanding the role of these compounds, particularly the distinction between hydrated states and their actual chemical functions in food.
