Bu çalışma, Türkiye’nin önemli havuç üretim merkezlerinden olan Konya ve Ankara illerinden temin edilen havuçların kimyasal ve biyoaktif bileşimlerini belirlemek amacıyla ele alınmıştır. Havuç örneklerinin kimyasal bileşimlerinin belirlenmesi amacıyla nem, kül, yağ, protein, karbonhidrat ve mineral içerikleri incelenmiş; biyoaktif bileşimlerinin belirlenmesi için ise β-karoten ve toplam fenolik miktarı ile DPPH testi kullanılarak antioksidan aktiviteleri ölçülmüştür. Konya ve Ankara yöresi havuçlarının mineral bileşikleri arasında Mg (sırasıyla 1145 ve 1033 mg/kg), P (sırasıyla 2250-3844 mg/kg), Mn (sırasıyla 15,4 ve 5,84 mg/kg), Zn (sırasıyla 14,8 ve 21,1 mg/kg) K (sırasıyla 26100 ve 26888 mg/kg) ve Fe (sırasıyla 26,0 ve 29,2) bakımından anlamlı farklılıklar olduğu görülmüştür. Konya havuçları toplam fenolik bileşik miktarı ve antioksidan kapasite değeri bakımından daha yüksek bulunurken (sırasıyla 7,71 mg/100 g taze havuç ve %33,5 inhibisyon), Ankara havuçları β-karoten miktarı (12,6 mg/100 g taze havuç) açısından öne çıkmıştır. Elde edilen sonuçlar, bölgesel farklılıkların havuçların besin ve biyoaktif bileşik içerikleri üzerinde belirleyici olduğunu ortaya koymaktadır.

Determination of Chemical and Bioactive Compositions of Carrots Grown in Türkiye

This study aimed to determine the chemical and bioactive compositions of carrots obtained from Konya and Ankara, two major carrot-producing regions in Türkiye. Moisture, ash, fat, protein, carbohydrate, and mineral contents were examined to determine the chemical composition of carrot samples. To determine their bioactive composition, β-carotene and total phenolic contents were measured, as well as antioxidant activity using the DPPH assay. Significant differences were found in the mineral compositions of Konya and Ankara regions’ carrots in terms of Mg (1145 and 1033 mg/kg, respectively), P (2250 and 3844 mg/kg, respectively), Mn (15,4 and 5,84 mg/kg, respectively), Zn (14,8 and 21,1 mg/kg, respectively), K (26100 and 26888 mg/kg, respectively), and Fe (26.0 and 29,2 mg/kg, respectively). Konya carrots were found to have higher total phenolic compound and antioxidant capacity (respectively 7,71 mg/ 100 g fresh carrot and %33,5 inhibition), while Ankara carrots were more prominent in β-carotene content (12,6 mg/100 g fresh carrot). The results suggest that regional differences significantly influence the nutritional and bioactive profiles of carrots.
