20.500.12556/RUL-146297 Quantification and distribution of primary and secondary metabolites in the inner and outer parts of strawberry fruit The distribution of primary and secondary metabolites within a fruit can affect its nutritional and organoleptic quality, as fruit can vary in size and shape. This study investigated the differences in the distribution of the primary and secondary metabolites in the fruit of four strawberry cultivars (‘Asia’, ‘Clery’, ‘Frederica’, and ‘Sandra’) that were collected at one harvest point. The study included an analysis of the individual sugars, organic acids, phenolic compounds, and enzymes responsible for the degradation of phenolics. All of the studied cultivars showed a lower pH, higher total organic acid content, and lower glucose and fructose content in the outer part of the fruit. Differences were also observed in the total phenolic and anthocyanin contents, which were always higher in the outer part. The absolute differences in the total phenolic content ranged from 3723 to 6154 mg kg$^{-1}$ dry weight. Our results provide a basis for understanding the differences in the biosynthesis of these metabolites within this fruit and prove that it is essential to mix samples well before extractions to obtain results that are representative of the whole fruit. strawberry fruit secondary metabolites primary metabolites phenolics anthocyanins sugars organic acids enzymes jagoda primarni metaboliti sekundarni metaboliti antocianini sladkorji fenolne spojine organske kisline encimi true false true Angleški jezik Slovenski jezik Članek v reviji 2023-05-23 10:20:18 2023-05-23 10:20:24 2025-08-08 13:22:22 0000-00-00 00:00:00 2023 0 0 13 str. iss. 5, art. 605 Vol. 9 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 634.1/.7 2311-7524 10.3390/horticulturae9050605 152997891 horticulturae-09-00605-v4.pdf horticulturae-09-00605-v4.pdf 1 38DBADE6AF55B1C38B3713F035B2A101 380add84bbc0f670cd1e9f6248cf7c19b0799236ebe972fc884c1009bcaf6267 5da8c796-ccd3-11ee-9559-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=180945 https://www.mdpi.com/2311-7524/9/5/605 1 6452a225-f942-11ed-a314-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=169449 Biotehniška fakulteta 0 0 0
