Summary

This study investigates whether organic or conventional carrot production yields measurably different total phenolic content, and how various drying conditions modulate this relationship. Non-destructive analytical techniques — likely near-infrared spectroscopy or similar — were employed to quantify phenolic compounds without sample destruction, offering methodological value alongside the agronomic comparison. The paper contributes to the evidence base on how production system and post-harvest handling jointly influence the phytochemical composition of root vegetables.

UK applicability

Whilst conducted in Turkey, the findings are broadly applicable to UK horticulture, where organic carrot production is well established and post-harvest drying is relevant to processing supply chains; UK growers and food scientists may find the non-destructive measurement methodology particularly transferable.

Key measures

Total phenolic content (mg GAE/100g or equivalent); drying method effects; organic vs conventional comparison; non-destructive spectroscopic or near-infrared measurements

Outcomes reported

The study measured and compared total phenolic content in organically and conventionally grown carrots subjected to different drying treatments. Non-destructive analytical techniques were applied to assess how farming system and post-harvest processing interact to influence phytochemical levels.
