| The term "Pineapple" is rather misleading, because the fruit is neither an apple nor a pine. The name ananas is of Guarani origin. South American Indians selected wild-growing ananas and it was spread to the West Indies before the Spanish conquest. It was brought to Africa, India and Southeast Asia by the Portuguese and the Spanish. Today major producers of pineapple are Hawaii, the Philippines, Brazil, Malaysia, Thailand, Formosa and Mexico. \\ | The term "Pineapple" is rather misleading, because the fruit is neither an apple nor a pine.

| | Dominant volatile ester compounds of fresh-cut pineapple (headspace SPME GC-MS) were methyl 2-methylbutanoate (1.0%), methyl hexanoate (2.2%), methyl 5-hexenoate (3.2%), ethyl hexanoate (1.2%) and ethyl 5-hexenoate (2.1%). Minor components were methyl (3-methylthio)propanoate, ocimene, 3,7-dimethyl-1,3,7-octatriene, ethyl (3-methylthio)propanoate, and methyl 4-octenoate e.g. \\ |

| "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." \\ | "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).

| "HRGC-MS analysis of juices made from fresh-cut fruit revealed the known prevalence of esters, with methyl 2-methylbutanoate, methyl 3-(methylthio)-propanoate, methyl butanoate, methyl hexanoate, ethyl hexanoate and ethyl 3-(methylthio)-propanoate, as well as 2,5-dimethyl-4-methoxy-3(2H)-furanone (mesifurane) and 2,5-dimethyl-4-hydroxy-3(2H)-furanone (furaneol) as major constituents. A corresponding flavour profile was rarely found in water phases/recovery aromas under study. In most cases, the characteristic methyl esters and hydroxy or acetoxy esters were lacking completely or appeared only in minor amounts in these products. Whereas a few of the commercial single strength juices revealed fruit-related flavour profiles, juices produced from concentrates mostly exhibited a flavour composition similar to that of concentrates, i.e. they were predominantly determined by their contents of furaneol and did not show the fruit-related ester distribution. Similarly, the jams under study were poor in typical pineapple constituents." \\ | "HRGC-MS analysis of juices made from fresh-cut fruit revealed the known prevalence of esters, with methyl 2-methylbutanoate, methyl 3-(methylthio)-propanoate, methyl butanoate, methyl hexanoate, ethyl hexanoate and ethyl 3-(methylthio)-propanoate, as well as 2,5-dimethyl-4-methoxy-3(2H)-furanone (mesifurane) and 2,5-dimethyl-4-hydroxy-3(2H)-furanone (furaneol) as major constituents.
