Development and Optimization of a Highly Sensitive Sensor to Quinine-Based Saltiness Enhancement Effect

Yifei Jing et al.

Summary: Adding specific substances to dietary salt can enhance saltiness, which has been used to develop low-salt food for promoting healthy eating habits. In this study, a new saltiness sensor was developed using a lipid/polymer membrane to accurately quantify the saltiness enhancement effect of quinine. Optimal concentrations of lipid and ionophore were determined for expected sensor response. The findings suggest the potential of using lipid/polymer membranes in taste sensors to evaluate saltiness enhancement.

Electrical Properties of Two Types of Membrane Component Used in Taste Sensors

Zhanyi Xiang et al.

Summary: PADE and TFPB were used as lipids to prepare two types of membrane electrodes. The ion selectivity of PADE membranes was consistently low, while the ion selectivity of TFPB membranes was concentration-dependent, increasing with higher TFPB concentrations. These results suggest potential for the development of innovative taste sensor receptive membranes.
