The Use of Low-Dose Electron-Beam Irradiation and Storage Conditions for Sprout Control and their Effects on Xanthophylls, Antioxidant Capacity, and Phenolics in the Potato Cultivar Atlantic

摘要: Low-dose electron-beam (e-beam) irradiation and storage conditions were evaluated for effectiveness in sprout control their influence on health-promoting compounds the potato cultivar Atlantic. Tubers subjected to zero 200 Gy stored at either 4 °C or ambient temperature 0, 10, 20, 75, 110 days before evaluation. Xanthophyll content (Xan), antioxidant capacity (AOC), phenolic (PC) quantified by spectrophotometric absorbance; xanthophyll with HPLC-DAD analysis. held during lost weight visibly dehydrated. exposed did not sprout; non-irradiated tubers sprouted, regardless of temperature. The exterior layer had greater total Xan, AOC, PC than interior layer, treatment. Storage time was most influential factor, affecting content. PC, chlorogenic acid increased within first 10 storage, then declined extended storage. Initially, AOC irradiated when compared samples; however, little no differences observed once Some samples experienced an increase Xan later stages believed be associated a concentration effect due dehydration. E-beam inhibited sprouting prominent health promoting retained.
