- •
It is difficult to predict SSC and firmness of pears using one permittivity value.
- •
Nonlinear models were better than linear models in SSC and firmness determination.
- •
SPA-ELM had the best comprehensive performance in predicting SSC and firmness.
- •
Dielectric spectroscopy had potential in developing pear maturity detector.
