Carotenoids and their geometry isomers in selected tropical fruits


Ying, Sze Wen and Khoo, Hock Eng and Kin, Weng Kong and Ismail, Amin (2013) Carotenoids and their geometry isomers in selected tropical fruits. International Journal of Food Properties, 16 (4). pp. 826-837. ISSN 1094-2912; ESSN: 1532-2386


This study determined the carotenoids content in cherry tomato, pink guava, and red grapefruit pulps and juices. Cherry tomato pulp exhibited the highest β-carotene content whereas pink guava pulp had the highest lycopene content. However, β-carotene and lycopene contents in the studied fruit juices were lower than their pulps in the same sample portion. Interestingly, six to twelve cis-isomers of carotenoids were identified in the fruit pulps and juices studied. A higher number of trace amounts of cis-carotenoids was found in fruit pulps as compared to juices. Therefore, consumption of whole fruit is recommended as the studied fruit juices have lower carotenoids content.
