Contents of Carotenoid in Different Strawberry Varieties During Maturing Stage

Carotenoid contents of the strawberries,Fu Mei No.1,Frandy,Nyoho,Red Pearl,and Hong Shi Mei,at various maturing stages and in different parts of the fruits were determined using UPLC.The results showed that the dominant carotenoids in the 5varieties of strawberries were lutein andβ-carotene.The total carotenoid contents were higher in Fu Mei No.1,Frandy,and Nyoho,and lower in Red Pearl and Hong Shi Mei.They were significantly higher in the outer parts than the core of the fruits.And,as Fu Mei No.1and Frandy strawberries were maturing,their carotenoid contents decreased,and the declines were most significant from the green to the white stage,as well as,from the pink to the red stage.
