Abstract
This study aimed to determine the response of potato starch granules to microwave radiation indicated by changes in starch granule size. Laboratory analyses were carried out in 2019 with tubers of an early edible potato cultivar Innovator. The tubers were irradiated for 10-600 s using a 100 W generator producing microwaves having a frequency of 2.45 GHz. Dimensions of starch granules were measured using an OPTICA B-510BF optical microscope and PROVIEW x64 software, 3.7.13483.20181206. The results were analyzed in STATISTICA 13.3. software package at a significance level of α=0.05. The microwaves were shown to significantly modify the maximal diameter and surface area of potato starch granules.
