The Effect of Different Storage Conditions and Package Size on Storage Duration of Carrots

Abstract

The effects of different storage temperatures and packing size on the storage period of the Nandor Pi carrot cultivar are reported. Storage temperatures were at a controlled O° and 5° C and at ambient temperature with assisted ventilation. Product was stored in 2-, 5-, 10-, and 20-kg perforated polyethylene PE bags for these experiments; control carrots were placed in each of the three temperatures but were not packed . At monthly intervals the stored carrots were evaluated for the following; total soluble solids, carotene content. weight loss, sprouting, rooting, and sensory quality. Results show that the unpacked carrots placed in 5°C refrigeration could be stored for up to two months. Unpacked controls stored in ventilated conditions or at O° C could be stored for as long as three months. Carrots packed in PE bags and placed in ventilated conditions could be stored for up to four months, while plastic-packed product placed in O° C refrigeration lasted for as long as six months. Sprouting and weight loss were found to increase as storage temperat ırre increased, whereas TSS was observed to decrease in contrast. For all storage conditions the carotene content of carrots stored in PE bags was uniformly higher at the end of the storage period than at the beginning of the storage period.
