* Area of the peak expressed as a mixture percentage of the total area of all integrated peaks in the chromatogram; Cal RI –Calculated Retention Index: It RI –Retention Index from literature’: \(\mathrm{Lit}\) RI from Pubchem and Chemepider database [10,4]; \(\mathrm{L}^{2}\) Oxford threshold based on the _diffewell_ A Associates website [36]; \(\mathrm{V}^{2}\) Other Threshold in water of volatile compounds identified in tomato fruits [10]; \(\mathrm{L}^{2}\) –Phenoyethanol was identified since it presents a chemical structure similar to phenoyethyl copyrate used for the preparation of macroemissions. Phenoyethyl copyrate it is not present in the library and therefore the software identified a similar compound.
