          Abstract

          RESUMEN La piña (Ananas comosus [L.] Merr.) es una de las frutas tropicales más importante y popular, debido al aroma y sabor atractivos. Varios cientos de variedades se cultivan en varias partes del mundo y que es conocido que poseen marcadas diferencias en sus características sensoriales. La aplicación de la extracción líquida-líquida combinada con la cromatografía de gases-espectrometría de masas y los valores de actividad del olor fueron usados para analizar los compuestos volátiles de las variedades de piña fresca Oromiel, Cayena y Manzana cultivadas en Colombia, y para estimar los compuestos más activos del aroma. Se identificaron 194 constituyentes, distribuidos en 183 (17,51 mg/kg), 173 (11,39 mg/kg) y 153 (9,14 mg/kg) compuestos en las variedades Oromiel, Cayena y Manzana, respectivamente. La composición de los extractos estuvo constituida mayoritariamente por ésteres, seguidos de aldehídos, alcoholes, ácidos, terpenos, furanos y otros de distinta naturaleza química, pero cuantitativamente fueron predominantes los ésteres y tioésteres. Las tres variedades coincidieron en tener como predominante al hexanoato de metilo con una nota de piña. Las variedades Oromiel y Manzana coincidieron en tener como segundo predominante al 3-(metiltio)-propanoato de metilo con una nota olfativa a bajas concentraciones que recuerda a la piña, mientras que en la Cayena fue el octanoato de metilo (nota frutal). Un total de 35, 37 y 30 compuestos son contribuyentes activos del aroma de las variedades Oromiel, Cayena y Manzana, respectivamente. La contribución al aroma de cada uno de ellos difiere según la variedad.

          ABSTRACT La piña (Ananas comosus [L.] Merr.) is one of the most important and popular of tropical fruits, mainly due to its attractive flavor. Several hundreds of varieties are grown in various parts of the world and are known to vary markedly in their sensory characteristics. Application of liquid-liquid extraction combined with gas chromatography-mass spectrometry and odor activity value was used to analyze volatile compounds from fresh pineapple varieties Oromiel, Cayena and Manzana grown in Colombia, and to estimate the most aroma-active compounds. A total of 194 volatile compounds were identified, which were distributed in 183 (17.51 mg/kg), 173 (11.39 mg/kg) y 153 (9.14 mg/kg) constituents in the varieties Oromiel, Cayena and Manzana, respectively. The composition of the extracts was constituted by esters, aldehydes, alcohols, acids, terpenes, furans and other of different chemical nature, but quantitatively esters and thioesters were predominant. Ethyl hexanoate was the major compound in the three varieties, with a pineapple note. Oromiel and Manzana varieties agreed with methyl 3-(methylthio)-propanoate as the second major constituent, with a pineapple-like note at low concentrations, while in Cayena pineapple was methyl octanoate (fruity note). A total of 35, 37 and 30 of them were aroma active compounds of the varieties Oromiel, Cayena y Manzana, respectively. The contribution of each one was different among the varieties.

          GC-O-MS technique and its applications in food flavor analysis

          Gas chromatography-olfactometry-mass spectrometry (GC-O-MS) is a combination of gas chromatography-olfactometry (GC-O) and gas chromatography-mass spectrometry (GC-MS). GC-O-MS technique is a powerful tool to study food flavors and it has been widely applied for aroma and flavor analysis of various food items. In combination with different technologies, GC-O-MS can be applied to solve many flavor problems in the food industry such as quick mapping of aroma-active compounds, identification of key aroma-active compounds, cluster analysis based on the aroma-active compounds, relationship between odorants and sensory properties, and clarification of formation mechanism of important odorants. The newly proposed "molecular sensory science" concept (or sensory-directed flavor analysis) provides a much deeper research for the GC-O-MS application. Here, we have reviewed the operation, advantages and applications of GC-O-MS technique. Qualitative/quantitative analysis methods and sampling methods of aroma-active compounds have been described to introduce the different application areas of GC-O-MS. Case studies based on existing papers and our research have been discussed.

              Odor-active constituents in fresh pineapple (Ananas comosus [L.] Merr.) by quantitative and sensory evaluation.

              By application of aroma extract dilution analysis (AEDA) to an aroma distillate prepared from fresh pineapple using solvent-assisted flavor evaporation (SAFE), 29 odor-active compounds were detected in the flavor dilution (FD) factor range of 2 to 4,096. Quantitative measurements performed by stable isotope dilution assays (SIDA) and a calculation of odor activity values (OAVs) of 12 selected odorants revealed the following compounds as key odorants in fresh pineapple flavor: 4-hydroxy-2,5-dimethyl-3(2H)-furanone (HDF; sweet, pineapple-like, caramel-like), ethyl 2-methylpropanoate (fruity), ethyl 2-methylbutanoate (fruity) followed by methyl 2-methylbutanoate (fruity, apple-like) and 1-(E,Z)-3,5-undecatriene (fresh, pineapple-like). A mixture of these 12 odorants in concentrations equal to those in the fresh pineapple resulted in an odor profile similar to that of the fresh juice. Furthermore, the results of omission tests using the model mixture showed that HDF and ethyl 2-methylbutanoate are character impact odorants in fresh pineapple.
