Integration of Physiological Analysis and Untargeted Metabolomics to Explore Differences in Quality Among Four Sweet Cherry Cultivars

This study compared the quality parameters of four popular sweet cherry fruits (“Ti- eton”, “Pioneer”, “Sunburst”, and “Huangmi”) in Shanxi Province and used untargeted metabolomics to analyze the differential metabolites (DMEs) among them. The results showed that the four fruits have distinct differences in their skin color, texture, size, weight, and solid-to-acid ratio. Notably, “Huangmi” fruit showed greater physical damage and bitterness and lower overall likeability than the other three...
