FuraneolTM was perceived more strongly in full-fat ice cream, while cis-3-hexen-1-ol, [alpha]- ionone, [gamma]-undecalactone and ethyl-3-methyl-3-phenylglycidate were perceived more strongly in low-fat ice cream. However, ice creams with Simplesse(R) and full-fat ice cream had similar sensory characteristics. Cooked sugar flavor, sweetness and their aftertastes were determinants for the degree of taste similarity with full-fat ice cream. The reformulated product, which was the closest in sensory characteristics to full-fat ice cream, was either the one in which the concentration of [gamma] undecalactone was decreased individually by 25% or the product, in which [gamma] undecalactone and cis-hexen-1-ol were decreased by 25%. No significant differences for consumer test between the reformulated products and full-fat ice cream. ; Includes bibliographical references.
