Chemical Properties

May contain ~3.0% 4-hydroxy-2,5-dimethyl-3(2H)-furanone.* Organoleptic characteristics: caramel, savory. Used in commercial meat flavors. First used in food in 1988.

Occurrence

Reported present in strawberry (0.001–0.01).

Uses

2,5-Dimethyl-4-oxo-4,5-dihydrofuran-3-yl acetate is furanone derivative; used in manufacturing method of silver nanowire by reacting silver salt in polyol in presence of growth regulator, halide salt, and specific furanone derivative.

Uses

This compound enhances the profile of brown flavors, including caramel, butterscotch, molasses, brown sugar, chocolate mocha, coffee and toffee. It will add to the sweet caramelic notes of browned butter, custard, dulce de leche, strawberry and other fruit jams, BBQ, fried eggs and roasted meat and nuts and soy sauce flavors.

Definition
