Oranges are processed to either not from concentrate (NFC) or from concentrate (FC) juice. Juice industry primarily provides FC for financial aspects, whereas consumers prefer NFC for quality reasons. By application of the sensory science concept to NFC and FC based on genuine sample material, key aroma compounds were characterized. Analysis of the latter in a great number of commercial NFC and FC and a correlation to sensory evaluation allowed conclusions on the acceptance. Thus, it is not the type of juice, but a specific balance of odorants that is responsible for the sensory acceptance. Investigation of juice fractions originating from FC-process indicated the influence of thermal treatment to the odorants` stability.
