3-(Methylthio)propionaldehyde Usage And Synthesis


Chemical Properties

CLEAR COLOURLESS LIQUID

Chemical Properties

3-(Methylthio) propionaldehyde has a powerful, onion, meat-like odor. It has a pleasant, warm, meat and soup-like flavor at low levels

Uses

3-Methylthiopropionaldehyde is a synthetic flavoring agent that is a colorless to light yellow liquid with an intense meat odor. it polymerizes with age and is stable in a 50% alcohol solution. it should be stored in glass containers. it is used at low concentrations for meat and broth flavors for applications in meats and condiments at 3 ppm and in baked goods and beverages at 0.5 ppm.

Preparation

By transamination and decarboxylation of various amino acids; by oxidation of the alcohol
