 The study investigates the effects of two stress inhibitors, particle film PF and dacarboxylic acid DA, on the aroma composition of beauty seedless and tecordag seedless grape cultivars using solid-phase micro-extraction technique with gas chromatography, GC, and mass spectrometry, MS. The study identifies a total of 36 and 24 aroma compounds in beauty seedless and tecordag seedless, respectively. The C6 compounds, hexanol and 2hexanol, are the most abundant compounds in both grape cultivars, accounting for 40.1% and 72.3% of total aroma composition in beauty seedless and tecordag seedless, respectively. Monoturpenes, geranium, narrow and naryc acid, and sesquiterpenes, alfeline gene germacrine have a significant contribution to the total flavor of beauty seedless. Benzophenone, maltul, 6-methyl 5-heptin 2-1, 2-ethylhexanol, 2-pentofuran, acetic acid, hexanoic acid are other compounds detected at the highest amount. In tecordag seedless, benzene acetaldehyde, 2-ethylhexanol, maltul, for hexan 1ol, acetic acid and hexanoic acid are determined as proportionally important compounds. The study finds that the effects of stress inhibitors on the aromatic composition of grape cultivars are limited, and the proportional levels of any aroma compounds could not be attributed to influence of the stress inhibitors. However, the findings contribute useful information for future studies. This is the first report on the aroma composition of beauty seedless and tecordag seedless grape cultivars.
