Abstract：The flavor of tomatoes is determined by the volatile compounds formed during the ripening process of tomatoes， which to a certain extent determines the choice of consumers to buy tomatoes. The substances that determine the flavor of tomatoes undergo dynamic changes during the ripening process of tomatoes， from initial release to aroma enrichment to depletion， and are affected by many factors. In order to understand how to speed up the preparation period of aroma material synthesis， prolong the accumulation period of aroma material enrichment， and reduce the loss period of aroma material as far as possible， the key ways and key substances of tomato aroma material synthesis were expounded， so as to provide reference for the improvement of tomato flavor quality.

Key words：Tomato; Fruit flavor; Aroma; Aromatic substances; Biosynthetic pathway; Impact factors
