Consumer's perception and expected liking of labels of burgers with sodium reduction and addition of mushroom flavor enhancer.

This study investigated consumers' perception of labels of burgers with sodium reduction and/or addition of mushroom flavor enhancer. Six visual stimuli were created using a factorial design with sodium content (regular, sodium-reduced, and sodium-reduced plus health claim) and flavor enhancer (monosodium glutamate (MSG) and mushroom extract) as factors. Consumers answered an attitudinal questionnaire and evaluated the stimuli through expected liking and check-all-that-apply (CATA) questions.
