Combining the high-intensity sweeteners’ positive synergy with response surface methodology (RSM), it is possible to optimize food and beverage products liking, masking undesired sensory attributes and reducing costs and consumers’ additives intake (up to 50%). A RSM based on a five-level, two variable central composite rotatable designs (CCRD) was applied, varying aspartame and acesulfame-K concentrations in order to optimize consumers’ sensory liking (n = 118) for peach nectar in terms of appearance, aroma, flavor, and overall liking. Statistically valid models were found for flavor and overall liking attributes and highest liking values were found for samples combining the two sweeteners (therefore overcoming acesulfame-K’s sensory limitations) in lower concentrations, confirming the synergetic effect and allowing cost reduction and less additives intake, without losing sensory quality.
