Mixing ethyl maltol, vanillin, and thyme when added to fishing bait can attract fish, making it easier for fish to take the bait.
Ethyl maltol is a food additive. It is a meat-flavored multi-functional flavoring agent, such as a repellent for bitter, fishy and unpleasant smells. It can also improve the taste and extend the storage period of food. The general addition amount is 0.003%.
