D-Allulose Taste-Modifying Mixture for Bitter Aftertaste Reduction

The patent introduces taste-modifying compounds (such as cyclotitrin, phyllodulcin, and other sweet taste-enhancing substances) as intermediary agents that mediate between the reduced sugar content and the desired sweetness profile. These compounds selectively enhance sweet taste sensations without contributing to the harmful metabolic effects of high caloric sugars, thereby resolving the contradiction between health benefits and taste quality.

The patent employs composite sweetening systems that combine multiple components: reduced high caloric sugars, alternative sweeteners (such as allulose, erythritol, or other sugar alcohols), and taste-modifying compounds. This composite approach allows the formulation to achieve both health benefits from reduced sugar and acceptable taste quality through the synergistic effects of the combined components, particularly the sweet taste-enhancing properties of the taste-modifying compounds.

The patent applies the principle of converting harmful factors into benefits by using taste-modifying compounds that specifically target and enhance sweet taste sensations while masking or counteracting the unwanted bitter and astringent after-tastes associated with conventional sweeteners. For example, certain compounds in the mixture can suppress bitter taste receptors while leaving sweet taste receptors activated, thereby converting the harmful bitter aftertaste into a beneficial pure sweet sensation.

The patent utilizes parameter changes by carefully controlling the concentrations and ratios of different sweeteners and taste-modifying compounds in the formulation. By adjusting these parameters, the patent optimizes the sweetness profile while minimizing unwanted after-tastes and improving heat stability. The specific ratios of taste-modifying compounds to sweeteners are tuned to achieve the desired sensory characteristics and stability properties.
