Course Goal / Objective
Flavor is one of the most important criteria affecting the sensory quality of foods. The flavor of a food is determined by its taste, fragrance components and texture. The aim of this course is to explain the mechanisms of defects and bad odors in foods and to teach ways to minimize them.
Course Content
Detection of defects and malodor in foods by sensory methods, determination of defects and malodors in foods by means of instrumental analysis, defects caused by packaging materials, defects caused by microorganisms, oxidative aggravation, defects caused by Maillard reaction, defects due to cleaning and disinfectants.
Course Precondition
