Sugar Contents and Composition in the Mature Fruit of Different Longan Cultivars
The sugar composition in the mature fruit of 37 longan cultivars were analyzed by using the method of high liquid chromatography.The data were subject to correlation analysis and clustering analysis,and the different longan cultivars were categorized.The TSS content was between 16.84％～27.34％,the soluble sugars were mainly composed of sucrose,glucose and fructose.Among them,the sucrose content was the highest among the three soluble sugars.Correlation analysis showed that the TSS content was very significantly positively correlated with sweetness and with total sugar content similar to the relationship between sweetness and total sugar content in longan fruit.Based on the sucrose/hexose ratio,the tested cultivars could be divided into three different types of sugar composition:sucrose-prevalent type,intermediate type,and hexose-prevalent type.
