Resumo

In carrot roots, reducing the percentage of mass and the occurrence of diseases are the leading causes of post-harvest losses during storage and marketing. Also, budding and rooting are indicated as the possible effect on the use of modified atmosphere in root vegetables and tubers. This study was conducted to compare forms of packaging and storage time on weight loss, percentage of sprouted roots and concentration of ? carotene in three carrot cultivars. The carrots were placed in shallow trays of polystyrene and wrapped with PVC film, and put two roots per tray, or in bulk. Then, the roots were stored in the dark at ambient conditions for 20 days Carrots stored with plastic film (PVC) remained commercially viable for up to 12 days. When stored in bulk showed weight loss of more than 5% in 4 days, which is not feasible to trade. The content of carotenoids was constant throughout the storage period for the in three cultivars.
