• Electrical polarization
• Dielectric constant
• Rheology
• Bacteria count

This study is based on the development of bacterial count quantification generated by medium dielectric variations and consequent polarization material release. The proposed approach is an action method for the fast detection of bacterial concentration in orange juice. The sensing method relies on bacterial attachment up to biofilm formation. Furthermore, different media provide more oxygen group content to enhance capacitance and self-discharge. The test took only 30 min and it provided the means for rapid bacterial detection in the juice industry.
