The application of headspace solid-phase microextraction (HS-SPME) and dynamic headspace purge & trap (P&T) combined with gas chromatog.-mass spectrometry and odor activity value was used to analyze volatile compounds from acerola (Malpighia emarginata DC.) pulp in order to determine their key aroma compounds Chemometric evaluation led to the selection of the most efficient fiber of 50/30μm divinylbenzene-carboxen-polydimethylsiloxane in capturing volatile compounds Optimum conditions for HS-SPME were established and a total of 70 compounds were identified in pulp by HS-SPME, while 69 compounds were identified by P&T. The most represented class of compounds in HS-SPME was esters, while in P&T, it was alcs. Among the large number of compounds identified, the most abundant were 4-pentenyl hexanoate, 4-pentenyl butanoate, hexyl butanoate and 1,4,4,7a-tetramethyl-2,4,5,6,7,7a-hexahydro-1H-indene-1,7-diol in the extract by HS-SPME while 3-methyl-3-buten-1-ol, ethanol, 1,4,4,7a-tetramethyl-2,4,5,6,7,7a-hexahydro-1H-indene-1,7-diol and 4-pentenyl butanoate were in P&T. Based on this study in association with the odor activity values, the key aroma compounds of acerola pulp were (Z)-β-ocimene, (E)-β-ocimene, Me butanoate, linalool, (E)-β-ionone, (E)-2-hexenal, decanal, (E)-β-damascenone, Me hexanoate, 3-methyl-3-buten-1-ol, heptanal, Et butanoate, Et hexanoate, 1-octen-3-ol and nonanal. These compounds are predominantly of fruity notes with the presence of sweet, herbaceous and fresh odors. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Synthetic Route of C8H16O2).
Methyl heptanoate (cas: 106-73-0) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Synthetic Route of C8H16O2
