“…Impedance spectroscopy can also be used for food materials such as meat (Bai et al, 2017;Oliver et al, 2001;Zhao et al, 2017), fish (Niu & Lee, 2000;Oliver et al, 2001), bread (Bhatt & Nagaraju, 2010;Daikuzono et al, 2017) and fruits and vegetables (Bera & Nagaraju, 2011c;Bera, Bera, Chowdhury, Ghoshal, & Chakraborty, 2017;Chowdhury, Singh, Bera, Ghoshal, & Chakraborty, 2017b;Chowdhury, Bera, Ghoshal, & Chakraborty, 2017a;Chowdhury, Bera, Ghoshal, Chakraborty, & Naresh Kumar, 2017c;El Khaled et al, 2017;Rehman, Izneid, Basem, Abdullah, & Arshad, 2011;Repo, Paine, & Taylor, 2002;Voz ary & D-n e, 1998;M esz aros, 2007) in terms of their frequency dependent electrical impedance calculated from the boundary voltage-current data measured by an array of surface electrode and an electrical impedance measuring instrumentation. EIS has been adopted by a several research groups for investigation of fundamental electrical properties of fruits and vegetables during ripening and storage.…”
