Overview

Automated platform enhances colorimetric sensor arrays, enabling fast discrimination of food samples using pH indicators.

Key Points

  • The system enables rapid discrimination of various food products based on their acid-base properties.
  • Data acquisition takes less than 1 minute, significantly enhancing efficiency compared to traditional methods.
  • Using an 8-channel digital light sensor improves the discrimination capability beyond conventional RGB models.
  • Principal component analysis and hierarchical cluster analysis were effectively utilized for data processing.
