一般描述
γ-Valerolactone has been identified as one of the volatile flavor constituents in mango and honey.
Natural occurence: Barley, beef, beer, Swiss cheese, coffee, cocoa, mango, milk, mushroom, peach, pork, tea, soy and tomato
应用
The sweet, creamy notes of this lactone will enhance coconut, vanilla, caramel, toffee, milk chocolate, and the sweeter dairy flavors like cajeta, milk and whipped cream. Dried fruit flavors like date and fig, and nut flavors like almond and peanut butter are also good destinations for this material.
