20.500.12556/RUL-184486 Mass loss, sucrose depletion and technological quality changes in sugar beet roots tubers during long-term field clamp storage under commercial conditions Izguba mase, upad saharoze in tehnološke spremembe koreninskih gomoljev sladkorne pese med dolgotrajnim skladiščenjem v komercialnih razmerah The study assessed changes in root mass, sucrose content, technological impurities, and microbial polysaccharides in sugar beet tubers during long-term field clamp storage under commercial conditions in the Western Forest-Steppe of Ukraine in 2024–2025. Tubers of commercial hybrids were stored in outdoor clamps and sampled after 0, 30, 60, 90, 120, 150, and 180 days. Tuber mass loss, sucrose content, K, Na, α-amino nitrogen, and dextran/levan accumulation were determined using standard analytical methods. Tuber mass loss increased from 0.85 % after 30 days to 9.20 % after 180 days. Sucrose content declined from 18.30 % at harvest to 17.17 % after 180 days, corresponding to a relative sucrose loss of 6.17 %. Potassium increased from 3.85 to 5.31 mmol 100 g-¹, sodium from 0.48 to 1.03 mmol 100 g-¹, and α-amino nitrogen from 11.8 to 27.8 mg 100 g-¹. Dextran/levan accumulation remained low during the first 90 days but increased sharply after 120 days, reaching 3.31 % by day 180. The results indicate that outdoor clamp storage should not exceed 120 days under these conditions. sugar beet clamp long-term storage sucrose content dextran levan technological quality α-amino nitrogen sladkorna pesa poljske jame dolgotrajno skladiščenje vsebnost saharoze dekstran levan tehnološka kakovost α-amino dušik true false false Angleški jezik Slovenski jezik Članek v reviji 2026-07-08 11:39:57 2026-07-08 11:40:01 2026-07-09 04:14:24 0000-00-00 00:00:00 2026 0 0 8 str. no. 2 Vol. 122 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 63 1854-1941 10.14720/aas.2026.122.2.25167 284038915 KYSELOV+et+al.+(N).pdf KYSELOV+et+al.+(N).pdf 1 5520606ACBA3C0E69C01572B1BAEDE81 f56543ce6e2face03cf3dcac532fbab4932ea41b4f17144832e06544a134cb3a 0bf65c6e-7ab1-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=237331 https://journals.uni-lj.si/aas/article/view/25167 1 ea5d86a4-7ab0-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=237330 Biotehniška fakulteta Acta agriculturae Slovenica 0 0 0
