THE INFLUENCE OF WASHING PROCEDURE ON THE ANTIOXIDANT CAPACITY OF DAUCUS CAROTA SUBSP. SATIVUS
Abstract
Carrots are in important source of antioxidants. The main compound that gives them antioxidant capacity is beta-carotene. Storage and post-harvest treatments can influence negatively the antioxidant capacity of carrots. In order to evaluate the impact of storage and washing procedure samples from Atomic Red and Royal Chantenay varieties were analyzed using Photochem instrument from AnalytikJena before washing, immediate after washing, after 15 day of storage at 8oC and after 45 day of storage at 8oC. The results are express in mg/kg equivalent TROLOX. There is a small loss of antioxidant capacity between the first day and after 15 days of storage, 3,86 % on average in the control batch respect to 9,47 % on average for the samples. Between the first day and after 45 days of storage there is a big loss of antioxidant capacity, 19,22% on average in the control batch respect to 24,86 % on average for the samples.
