Description

Abstract: Proportions of peanutextract, cottonseed oil, and water in liquidwhitener were optimized. Eighty-four consumers rated the performance and sensory characteristics of a commercial control and 12 whitener blends containing varying proportions of extract, oil, and water. Solubility, whitening power, color uniformity, and appearance acceptability of blends containing 0.533, 0.367, or 0.200 peanutextract and no oil were not significantly different from the control. The control had flavor acceptability significantly higher than all experimental blends and overall acceptability not significantly different from a blend with 0.367 peanutextract and no oil. Responses of all dependent performance and sensory variables to the component blends studied were predicted by reduced cubic polynomials. Overall acceptability was the limiting response for the optimum product. Use of over 0.50 peanutextract in the blend resulted in unacceptable products. The maximum amount of oil in an acceptable formulation was 0.01 of the component blend. This was blended with 0.20 extract. Acceptable oil levels decreased with increasing extract levels. Optimum formulations had consumer ratings of at least 7.5, 6.0, and 6.5 for solubility, whitening power, and color uniformity, respectively.
