Carrot (Daucus carota L.) is a biannual plant that accumulates massive amounts of carotenoid pigments. The current research focuses on the changes of carotenoid composition, i.e., the total carotenoid and β-carotene content in Nantes type carrots during storage in traditional conditions. Carotenoid composition during carrot storage for six months at the temperature 4±1 °C and relative air humidity 89±1% was evaluated using spectrophotometric methods. The results revealed the tendency that total carotenoid content in carrots after six months of storage increased by 31.12–40.97% in average and β-carotene by 7.89–32.99% which is significantly (p is less than 0.05; α=0.05) higher.
