Carotenoids, total phenolics and anti-oxidant activity of carrots were determined during 6 months of storage at 0°C, 85-90% relative humidity. In addition to changes in CIE colour parameters (L*, a*, b*, h and C), physicochemical properties of carrots including water soluble solids; pH and titratable acidity were evaluated. Cold storage of carrots did not affect the carotenoid levels (b-carotene, a-carotene and total carotenoid) except lutein, which showed a 37.5% loss. Total phenolic concentration of carrots decreased significantly (P < 0.05) over the entire storage period. The anti-oxidant activity of carrots decreased with a level of 31% and was found correlated with total phenolics and lutein content in carrots. While CIE L* and a* parameters decreased significantly (P < 0.05) after 6 months of storage, the b* and C parameters were statistically unchanged for the first 4 months of storage, but decreased gradually for the following period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
