Última Three-Year Comparison of the Polyphenol Contents and Antioxidant Capacities in Organically and Conventionally Produced Apples (Malus domestica Bork. Cultivar `Golden Delicious') Organic Eprints Stracke, Berenike A.; Rüfer, Corinna E.; Weibel, Franco; Bub, Achim; Watzl, Bernhard. The present study was performed to evaluate the polyphenol content and antioxidant capacity of apples (cv. `Golden Delicious') grown under defined organic and conventional conditions. Apples were harvested at five comparable commercial farms over the course of three years (2004−2006). In 2005 and 2006 the antioxidant capacity was 15% higher (p < 0.05) in organically produced apples than in conventionally produced fruits. In 2005 significantly higher polyphenol concentrations were found in the organically grown apples. In 2004 and 2006 no significant differences were observed (2004, 304 ± 68 μg/g organic vs 284 ± 69 μg/g conventional, p = 0.18; 2005, 302 ± 58 μg/g organic vs 253 ± 41 μg/g conventional, p = 0.002; 2006, 402 ± 100 μg/g organic vs 365 ± 58...

Background The organic food sales have been increasing during the recent years. It has been hypothesised that organically grown fruits are healthier based on their higher content of phytochemicals. However, data on the bioavailability of phytochemicals from organically or conventionally produced plant foods are scarce. Methods Two human intervention studies were performed to compare the bioavailability of polyphenols in healthy men after ingestion of apples from different farming systems. The administered apples were grown organically and conventionally under defined conditions and characterised regarding their polyphenol content and antioxidant capacity. No significant differences in the polyphenol content and the antioxidant capacity from the... Tipo: Journal paper Palavras-chave: Food security; Food quality and human health Fruit and berries. Ano: 2010 URL: http://orgprints.org/17951/1/strake%2Detal%2D2010%2Deur%2Dj%2Dnutr.pdf Sind Bio-Äpfel gesünder? Organic Eprints Stracke, Berenike A.; Briviba, Karlis; Bub, Achim; Rüfer, Corinna E.; Watzl, Bernhard. Viele Verbraucher, die sich beim Kauf von Lebensmitteln für Bioprodukte entscheiden, erhoffen sich davon gesundheitsfördernde Effekte. Allerdings liegen bis heute noch nicht genügend wissenschaftliche Daten vor, um ökologisch und konventionell erzeugte Lebensmittel vergleichend ernährungsphysiologisch bewerten zu können. Am Institut für Ernährungsphysiologie der Bundesforschungsanstalt für Ernährung und Lebensmittel (BfEL) wird zurzeit untersucht, ob sich verschiedene pflanzliche Lebensmittel aus ökologischer und konventioneller Anbauweise hinsichtlich ihres Gehaltes an sekundären Pflanzenstoffen und deren ernährungsphysiologischer Wirkung am Menschen unterscheiden.

The present study was performed to evaluate the concentrations of phytochemicals (carotenoids and phenolic acids) in wheat varieties grown under comparable organic and conventional conditions over three years as part of a long-term field trial. Phenolic acids of the hydroxybenzoic acid and hydroxycinnamic acid group were quantified by HPLC-DAD after extraction as free, soluble conjugated, and bound forms. Furthermore, the carotenoids lutein and zeaxanthin were determined by HPLC-DAD. There were no statistically significant differences between the two farming systems (sum of carotenoids (microg/g) for 2003, 0.91 +/- 0.55 organic vs 0.96 +/- 0.34 conventional; for 2005, 1.61 +/- 0.22 organic vs 1.33 +/- 0.19 conventional; for 2006, 0.87 +/- 0.33 organic vs...
