Flavour profiles of three novel acidic varieties of muskmelon (Cucumis melo L.)

Sensory and instrumental analysis of medium and long shelf-life Charentais cantaloupe melons (Cucumis melo L.) harvested at different maturities

“…A number of these odours were detected in our previous study (Lignou et al, 2013); however, the identities of many of these compounds remain unknown. A number of compounds were positively identified including (Z)-3-hexen-1-ol with a very strong cut grass odour in mMSL genotype.…”

“…3-Chlorophenol (100 μl of a solution containing 1 mg/ml in 10% methanol/water) was added to the filtrate (20 ± 0.1 ml) as internal standard and the extraction was performed as described by Lignou, Parker, Oruna-Concha, and Mottram (2013).…”

“…Extracts were analysed by an Agilent 6890/5975 GC–MS as described by Lignou et al (2013). Semi-volatile compounds were identified as described above for the volatile compounds.…”

Aroma volatiles obtained at harvest by HS‐SPME/GC‐MS and INDEX/MS‐E‐nose fingerprint discriminate climacteric behaviour in melon fruit

“…The data of experimental spectra were compared with the spectra of the NIST05 (version 2.0d) library data bank and validate by comparison of linear retention indices (LRIs) calculated with a homologous series of n ‐alkanes (C 6 –C 20 ; Sigma‐Aldrich, St. Louis, MO, USA) analysed under the same conditions. The concentration of the individual aroma volatile compounds identified (expressed as ng mL −1 of juice) was quantified from the relation between their areas and that of the internal standard (1‐phenylethanol), obtained from the total chromatograms, using a response factor of 1 …”

Extraction techniques for analysis of aroma compounds

“…A number of compounds that are important in muskmelon aroma, including the polar aroma compounds homofuraneol (2-ethyl-4-hydroxy-5methyl-3[2H]-furanone) and norfuraneol (4-hydroxy-5-methyl-3[2H]-furanone), could not be detected using headspace adsorption onto Tenax TA but were successfully extracted using SPE (Lignou et al, 2013(Lignou et al, , 2014. Strata-X cartridges (Phenomenex, Torrance, CA), containing a functionalised styrene-divinylbenzene polymer, have been used with some success for the analysis of polar aroma compounds in strawberries and melons.…”
