Summary
This summary is machine-generated.This study characterized a unique black carrot variety from Cuevas Bajas, identifying key phenolic compounds and sugars. Medium-sized carrots and late-season harvests showed higher beneficial compound levels.
Area Of Science
- Agricultural Science
- Food Science
- Biochemistry
Background
- Black carrot (Daucus carota) is known for bioactive compounds and antioxidants.
- The Cuevas Bajas black carrot variety has a distinct black/purple core.
- Understanding this autochthonous variety's composition is important.
Purpose Of The Study
- Characterize the Cuevas Bajas black carrot variety.
- Analyze antioxidant capacity, carotenoids, sugars, and phenolic compounds.
- Investigate the influence of root size and harvest season.
Main Methods
- Analyzed 144 samples using three antioxidant capacity assays.
- Quantified total carotenoids.
- Profiled sugars and phenolic compounds using ultra-high performance liquid chromatography coupled to high-resolution mass spectrometry (UHPLC-MS).
Main Results
- Quantified 20 polyphenolic compounds, with anthocyanidins being most abundant.
- Detected pelargonidin 3-sambubioside for the first time in black carrot.
- Medium-sized carrots had higher phenolic compounds; small carrots had higher simple sugars.
- Late-season carrots showed increased glucose and fructose; early-season carrots had more sucrose.
- Total carotenoid content did not differ significantly.
Conclusions
- Root size and harvest season significantly impact the biochemical profile of Cuevas Bajas black carrots.
- This variety is a valuable source of anthocyanidins and other bioactive compounds.
- The findings contribute to understanding local crop diversity and potential applications.
