Hydroxy-gamma-lactones Enhance Creaminess and Mask Bitterness

The patent introduces a specific class of compounds (hydroxy-γ-lactones with particular molecular structures where A is selected from specific moieties, n is 0-7, and Z is C1-7 linear alkane) that fundamentally changes the chemical parameters of the taste modifier. These compounds operate at extremely low concentrations (0.01-100 ppm) to simultaneously achieve bitter taste masking and creaminess enhancement, resolving the contradiction by finding optimal molecular structure parameters rather than using conventional modifiers at higher doses.

The invention employs composite molecular structures combining specific functional groups (hydroxy group at position 8 or 9, γ-lactone ring, variable alkane chain) to create compounds that perform multiple functions. The dual functionality of these composite molecules allows them to interact with both bitter taste receptors and creaminess perception pathways, achieving simultaneous masking and enhancement effects that single-function compounds cannot provide.

The patent utilizes the parameter of concentration efficiency, demonstrating that the specific hydroxy-γ-lactone compounds achieve creaminess enhancement at 0.01-100 ppm concentrations. This extreme concentration efficiency allows mouthfeel improvement without the need for high doses that would alter the natural flavor profile, as the compounds work through specific molecular interactions rather than bulk sensory effects.

The hydroxy-γ-lactone compounds act as molecular intermediaries that mediate between the consumer's perception and the actual product composition. These compounds create the sensation of creaminess through specific receptor interactions without requiring physical cream or high concentrations of flavorants, thus preserving the natural flavor profile while achieving the desired mouthfeel through a mediating chemical substance.
