Effect of Biofortification with Iodine by 8-Hydroxy-7-iodo-5-quinolinesulfonic Acid and 5-Chloro-7-iodo-8-quinolinol on the Chemical Composition and Antioxidant Properties of Potato Tubers (Solanum tuberosum L.) in a Pot Experiment

Iodine deficiency impacts on the development of thyroid disease. Vegetables and fruits usually have a low iodine content; hence, it makes sense to increase their content. Potato is consumed daily by millions consumers would, therefore, be good target for biofortification with programs. The aim this study was determine effects via application soil solutions two iodoquinolines [8-hydroxy-7-iodo-5-quinolinic acid (8-OH-7-I-5QSA) 5-chloro-7-iodo-8-quinoline (5-Cl-7-I-8-Q)] KIO3 (as an positive control) content basic chemical composition, macro micronutrient content, nitrogen compounds, vitamin C, antioxidant potential potato tubers Solanum tuberosum L. process had no significant effect tuber weight in yield. I forms KIO3, 8-OH-7-I-5QSA, 5-Cl-7-I-8-Q resulted (1400.15; 693.65; 502.79, respectively, compared control, 24.96 µg·kg−1 d.w.). This also decrease elements that are harmful consumers, such as: Al, Ni, Cr, Ag, Pb Tl. enrichment 8-OH-7-I-5QSA reduction ammonium ions (from 19.16 14.96; 13.52 mg∙kg−1 f.w.) chlorides 423.59 264.92; 265.31 f.w.). Biofortification improved polyphenolic profile from 197.31 233.33 mg GAE·100 g−1 f.w. A carotenoid after plant 3.46 2.96, 2.45, 1.47 mg∙100 d.w., respectively) observed. It can postulated production potatoes enriched and/or worthwhile, as provide source diet simultaneously reduce risk developing deficiencies.
