Research papers concerning the sugar and organic acid compositions and contents of wolfberry fruit are scarce.
The characteristics of sugar and organic acid compositions and contents in different cultivars are not well known.
The objective of this study was to compare the changes in sugars, organic acids and LBP in three cultivars at
five ripening stages, analyse the composition of sugars and organic acids in wolfberry fruit and to find correlations
between LBP content and free sugars. Our findings will provide useful information for improving the flavour and
especially the nutritional quality of wolfberry fruit via enhancing the content of LBP.
