Abstract

Abstract: Butters, margarines and table spreads are water‐in‐oil emulsions. Melting characteristics of these products are important for flavor release and consumer acceptance. One characteristic that is believed to discriminate butters from margarines is a cooling sensation perceived in‐mouth while consuming these products. Here, we investigated different methods to characterize sensorically and analytically the "cool‐melting" properties of commercial butter and margarines. Our results show that butter indeed can be distinguished from margarines based on their "cool‐melting" properties. Furthermore, changes in enthalpy as measured through DSC and solid fat content are good predictors of the "cool‐melting" effect of spreads. Practical applications: By understanding the mechanisms of the "cool‐melting" perception of spreads, and linking them to analytical measurements, we can create an in‐vitro quantification method of "cool‐melting." This method can eventually help directing product development to achieve the desire product profile and increase consumer acceptance and liking of margarines and low‐fat spread products. In this study we did not assess the impact of "cool‐melting" on consumer perception, which would be the next step in understanding the drivers of liking of spread products.
