The Food Additives Committee of the Food and Agriculture Organization of the United Nations and the World Health Organization stipulates that the per capita daily intake of ethyl maltol should not exceed 2 mg kg- 1. Therefore, the guiding dosage in food processing is 100 ~ 200 pg kg- 1.
The maximum dosage of ethyl maltol can refer to the recommended dosage of the manufacturer. Reference dose in some foods:
Seasoning (chicken essence) 20 ~ 60 mg/kg; 60 ~ 130mg/kg of meat and fish (processed products); Ice cream, frozen food, jelly, tomato soup and other soups 5 ~15 mg/kg; Chocolate coating, candy, chewing gum and dessert 30 ~ 50m g/kg；; Meat products, sausages, seafood, etc. It can be added appropriately or adjusted appropriately according to the product characteristics.
The extended data identification method is as follows
1. Appearance identification method: ethyl maltol is white granular crystal with luster, while the counterfeit is white powder with no luster.
2. Direct tasting method; Fake goods are sweet, but genuine goods are bitter.
3. Heating identification method: put a small amount of ethyl maltol on tin foil paper (or thin iron sheet) and heat it with alcohol lamp or lighter. After heating, ethyl maltol will melt. If heating is continued, the melted ethyl maltol will completely evaporate without leaving any impurities. When counterfeit or low-purity ethyl maltol is operated according to the above method, burnt substances will be left on the tin foil paper. ?
4. Dissolution method; Ethyl maltol is hardly soluble in water at room temperature (the solubility in water is 1: 55), the crystal sinks to the bottom of the water, and the liquid is clear and transparent. Counterfeit products are easily soluble in water, and if they contain starch, they are turbid.
