文摘

Measurements of multiphase grape pomace ethanol-water mixtures permittivities. An empirical model is proposed to calculate multiphase system dielectric properties. Model variables are temperature, solvent composition and solid-liquid ratio. Grape pomace boosts ionic conductivity by releasing ions into the solvent. Solvent composition revealed as the most influential variable.
