| essence and spice | chicory ketone is also listed as methyl furanone. it is a kind of furanone essence and spice product. it is white or light yellow solid at room temperature and has strong caramel aroma. it also has toast, fruit flavor and jam flavor. its flavor strength is slightly weaker than furanone, but its performance is more stable than furanone and its price is lower. It is an important raw material and a good flavoring agent for sweet flavor. The flavor threshold of 0.04ppb has obvious flavoring and modification effect. It has been widely used in coffee, chocolate, bread and other foods, beverages, and tobacco. It can also be used in daily chemical products. It is a safe edible flavor (registration number: FEMA3635) approved by FEMA of the American Association of Edible Fragrance Manufacturers. It is recommended to use or store in a sealed container protected by nitrogen immediately after opening. furanone, also known as pineapple ketone or strawberry ketone, is a new flavor synergist with a planar cyclic enolone structure popular in recent years. It has a strong roasted caramel flavor, and its characteristic aroma is fruity aroma, caramel aroma, caramel and pineapple-like aroma. White to light yellow crystals or powdered solids, slightly soluble in water, easily soluble in organic solvents such as ethanol. Natural products are widely found in strawberries, oats, cheese, boiled beef, beer, cocoa, coffee, tea, mango, litchi, malt, gooseberry, grape, heated beef, pineapple, citrus and other fruits. In 1965, J.O.Rodin and others separated furanone from the ethanol extract of pineapple juice for the first time and determined its molecular structure. |
