The enhancement of the perception of saltiness by Sichuan pepper oleoresin in a NaCl model solution.

Health concerns related to the intake of salt have necessitated the investigation into NaCl reduction by examining the cross-modal interaction between the perception of saltiness and pungency elicited by Sichuan pepper oleoresin (Spo). The category scale and the generalized Labeled Magnitude Scale (gLMS) were used to determine the degree to which Spo enhanced the perception of saltiness in the NaCl model solution. Sixty-eight participants were divided into the hyposensitive, semi-sensitive, and hypersensitive groups according to individual exponent.

The relationship between alkylamide compound content and pungency intensity of Zanthoxylum bungeanum based on sensory evaluation and ultra-performance liquid chromatography-mass spectrometry/ mass spectrometry (UPLC-MS/MS) analysis.

Background: Zanthoxylum bungeanum originating in different places varies in alkylamide content and pungency intensity.

Results: The pungency intensity of 19 Zanthoxylum bungeanum samples was first determined with Scoville pungency units (SPUs). The SPUs were found to range from 3.
