The profile of volatiles in squids was characterized using simultaneous distillation-extraction coupled with comprehensive two-dimensional gas chromatog. (GC) and Time-of-Flight mass spectrometry (GC×GC-TOFMS). GC×GC-TOFMS improved the resolution and separation efficiency of the compounds; it not only separated the 52 compounds that co-elute in conventional GC-MS, but also allowed the identification of compounds that were not previously detected (e.g. 2-Octanol). The total contents of volatiles detected by GC×GC-TOFM were about 2.5-fold higher than those analyzed by GC-MS. Among 184 volatiles identified by GC×GC-TOFMS, 119 compounds were reported for the first time in squids, compared with the GC-MS data available in the literature. These volatile classes included aromatic hydrocarbons (39), aliphatic hydrocarbons (22), esters (21), aldehydes (20), alcs. (19), sulfo compounds (18), nitrogenous compounds (17), ketones (14), acids (6), furans (5) and phenols (3). This study proposes a methodol. and presents data that could be used to determine the volatiles in seafood. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Recommanded Product: 5444-75-7).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. 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.Recommanded Product: 5444-75-7
