Abstract: To elucidate the main factors that affect the flavor of cherry tomato (Solanum lycopersicum Mill. var. cerasiforme), the flavor and nutrient substances were analyzed through technical means as high efficiency liquid chromatography (HPLC) etc. The results showed that the coefficient of variations (CV) of malic acid, citric acid, ascorbic acid (Vc) and total amino acids are relatively higher compared with other flavor determination parameters. Among the 16 tested varieties, Zheyingfen No. 1, Zheyinghuang No. 1 from Vegetable Science Institute of Zhejiang Agricultural Academic Science (ZAAS), Huangfei from Golden Seedling Company of Japan, Tianzhenghongzhu from Vegetable Science Institute of Shandong Agricultural Academic Science (SAAS) were top-ranked in the flavor evaluation, and 7 of their flavor determination parameters (soluble solids, total sugar, organic acid, fructose, glucose, citric acid, and Vc) were significantly higher than those of backward ranked correspondences. Further analysis indicated that the flavor score was positively correlated with parameters including soluble solids, total sugar, organic acid, fructose, glucose, ascorbic acid, but showed no significant correlation with compound parameters such as total sugar/titratable acid etc. Based on the results, we proposed that the main flavor determination parameters should be soluble solids, soluble sugar (fructose+glucose), organic acid (mainly citric acid) and Vc. Additionally, total amino acids, as traditional nutrient components, might also be correlated with tomato flavor.
