Carotenoid Composition And Vitamin A Value Of Brazilian Loquat (eriobotrya Japonica Lindl.).

Six sample lots of loquat commercialized in Campinas, Brazil were analyzed for their carotenoid composition beta-carotene (7.8 micrograms/g), zeta-carotene (0.1 micrograms/g), neurosporene (1.1 micrograms/g), beta-cryptoxanthin (4.8 micrograms/g), 5,6-monoepoxy-beta-cryptoxanthin (0.6 micrograms/g), violaxanthin (1.6 micrograms/g), (0.8 micrograms/g) and auroxanthin (0.9 micrograms/g) were identified beta-Carotene and beta-cryptoxanthin were the principal pigments, being responsible for 44% and 27%, respectively, of the total carotenoid content (17.6 micrograms/g). Both were also the principal contributors to the vitamin A value of 175 RE/100g. The carotenoid composition of the Brazilian loquat resembles that of the Japanese loquat variety Tanaka.45433633
