Which mycotoxin is water-soluble and heat-stable?

Explanation:
Water solubility and heat stability in mycotoxins are tied to their chemical structure and how they interact with water and heat. Fumonisins have polar, hydrophilic groups that make them readily dissolve in water, so they can contaminate foods that involve aqueous processes. They are also relatively resistant to heat, meaning cooking temperatures don’t completely destroy them. The other toxins are less water-soluble, being more lipophilic or poorly soluble in water, and while they can be heat-stable, they don’t exhibit the strong water solubility seen with fumonisins. So fumonisins best fit the combination of water-soluble and heat-stable.
