The Prospect of Electrical Impedance Spectroscopy as Nondestructive Evaluation of Citrus Fruits Acidity

Abstract

Main objective ol the prnrnt work was to invndcate the Garut citrus fruits acidity mine electrical impedance me-remmts. Furthermore., the mrasunmmts ol electrical properties or Garut citrus fruits Wett c:mdudrd at various In-els ol pH and frequencies. This is done as a first step in order to n-aluate the Garut citrus fruits Kidity that does not damace il The electrical paramders have si,,Uficant responK to acidity ol Guut citrus fruits. 'Ille chances of acidity lead to ch•ca in electrical properties or fruits. Resistance per wdght, nactance per wdcfit, inductance per wdght, and impedance per wdght or Garut citrus fuits dtdined whm the pH is increased. Whik the capacitance per wdght or the Garut citrus fruits incttaes as pH incnues. The correlations betwem pH and electrical paramders are estimated by usinc multiple ~ons equatiOIL Their correlation was highly linear at frequency ol l Mlh. Those estimation equations an the primary basis in nondestructive dderminin& of Garut citrus acidity with electrical impedance measuttmmls.
