Ethyl maltol is easy to form a complex with iron, and will gradually change from white to red after contact with iron. Therefore, the use of iron containers should be avoided when storing, and the solution should not be in contact with iron for a long time. It is advisable to store it in glass or plastic containers.
Usage and precautions of ethyl maltol in whole grain baking: 1. Generally, when in use, 0.25% solution is prepared with hot water or alcohol and glycerol, and then the best addition amount is selected through experiments to avoid direct addition, so as not to be insoluble and unable to play a role.
2, the amount should not be too much, when excessive, the effect will be counterproductive and self-defeating.
3, used for baking food, should choose to join when the clarity is low, the effect is better.
4. Ethyl maltol is very sensitive to iron-containing substances and will turn purple when combined with iron ions; Avoid contact with iron-containing substances in the production process, especially when the concentration is high, be more careful; Ethyl maltol can be used in meat processing. On the one hand, it can interact with amino acids to enhance the flavor of meat. More importantly, it can be used in combination with iron salt as appropriate, and can replace nitrite to keep the roast meat in the can pink.
5. Ethyl maltol will appear yellow when it meets alkali. When the color of some products cannot be yellow, alkaline raw materials should be avoided.
