A quantitative predictive model for creamy mouthfeel in dairy desserts was developed, using PLS multivariate analysis of texture attributes. Based on 40 experimental custard desserts, a good correlation was obtained between measured and predicted creamy mouthfeel ratings. The model was validated by testing it for commercial custard desserts (r=0.84, p=0.002). Further validation was obtained by applying the model to commercial yoghurts, using a different panel. Again a good correlation was obtained (r=0.90, p
