Addition of three natural flavoring materials, hydrolyzed vegetable protein (HVP), hydrolyzed animal protein (HAP) and yeast extract (YE), into 0.2 M cystine-0.1 M lactose-0.1 M maltose solution (control) was studied for development of meat-like flavor by Maillard reaction.

Addition of three natural flavoring materials, hydrolyzed vegetable protein (HVP), hydrolyzed animal protein (HAP) and yeast extract (YE), into 0.2 M cystine-0.1 M lactose-0.1 M maltose solution (control) was studied for development of meat-like flavor by Maillard reaction. The HVP, HAP and YE were added individually at various concentrations and were mixed at selected concentration in order to compare their effects. The absorbance, color, sensory characteristics and volatile compounds of the solutions after the reaction at $100^{\circ}C$ for 8 hr were measured. The results showed that the absorbances of reaction solution at 420 nm and 278 nm were increased as reaction time and the concentration of the natural flavoring material increased. Also ‘L’ values of reaction solutions added with HVP, HAP or YE decreased while the ‘b’ value increased slightly. From the results of sensory evaluation 1.16% HVP, 0.94% HAP, 1.48% YE or 1.16% HVP + 0.94% HAP were selected as the appropriate substrates for the meat-like flavor development. The volatile compounds identified by GC/MS for the control and those added with 1.16% HVP or 1.16% HVP+0.94% HAP were 1 hydrocarbons, 9 aldehydes, 5 ketones, 1 ester, 5 alcohols, 2 aromatics(benzene), 2 furans, 1 sulfur compound.
