This session will discuss an evaluation of expeller-pressed chili pepper extracts for the presence or absence of lipid oxidation notes using aroma only. Results showed a strong, positive relationship between total aldehydes and the frequency of lipid oxidation detection by the untrained assessors. Another presenter will discuss the influence of lipid oxidation on the flavor profile and product acceptance of whole wheat bread. The session will also examine the ability to smell individual sensory-active compounds and determine their identity, to create the highest-quality food products.
