The key metabolite of fruit flavor change in different ripening stages of .

has an unstable ripening period. Herein, five typical periods of fruit ripening of 'LR' were analyzed by non-targeted metabolomics techniques. The results showed that ripening started 73 days after flowering and reached the ripening criterion at 93 days, a total of 451 differential metabolites were identified for the five periods.

Non-targeted metabolomics reveals the taste variations during Lour. fruit maturation.

Lour. is a new kind of underutilized wild fruit tree; the metabolic reasons for its fruit flavor changes are not yet clear. In this study, the pink flesh of this excellent tasting fruit (BR) was used to reveal the metabolic causes of taste variations through five developmental stages.
