Changes of carotenoids composition of yellow peach during fruit development
摘要
Abstract
[Objective]The study was to analyze the relationship between carotenoids composition, content and fruit color of yellow peach during fruit development. [Method] Acetone was used as extraction solvent. 'Xiang Jin Pan', 'Independence' and 'Frederic' were as experimental material. The total carotenoids content was tested by UV spectrophotometer. The carotenoids qualitative and quantitative analysis at different development stages of peach fruit were conducted by High Performance Liquid Chromatoqraphy (HPLC).[Result]The flesh color of 'Xiang Jin Pan' was light yellow 'Independence' was golden yellow and ' Frederi' was orange yellow at mature stage. As the yellow color deepened, the total carotenoids content in pericarp of ' Xiang Jin Pan' decreased, but kept stable in ' Independence' and increased gradually in ; Frederic;. The total carotenoids content in mesocarp of three varieties increased as the fruit developed and it was the highest in the deepest yellow peach ' Frederic'. The fruits of three varieties all contained five main carotenoids compositions Xanthophyll, Zeaxanthin, β -Cryptoxanthin, α -Carotene and β-Carotene. The variation trend of Xanthophyll in pericarp was the decrease along with the fruit development while the trends of Zeaxanthin, β-Cryptoxanthin and α-Carotene were contrary. The variation trend of β-Carotene in pericarp was similar to that of the total carotenoids content. The variation trends of Xanthophyll and Zeaxanthin in mesocarp were similar to that in pericarp. But the trends of β-Cryptoxanthin, α-Carotene and β- Carotene were different.[Conclusion]β-Carotene played a main role in affecting yellow color, followed by β-Cryptoxanthin and α-Carotene. The ratio of β-Cryptoxanthin and α-Carotene had big concern. The bigger the ratio, the deeper the yellow color. Then the color of β-Cryptoxanthin was reflected to orange yellow, while α-Carotene was reflected to light yellow.关键词
