“…Terpenes are common aroma compounds in dairy products and have previously been associated with the forage of the animals providing the milk (Bendall 2001;Havemose et al 2007;Tornambe et al 2006;Viallon et al 2000). This also explains why milk-based formulas exposed six terpenes, whereas α-pinene was the only terpene represented in powder formulas.…”

It has been suggested that mother's milk has a more diverse flavor composition than infant formula milk as it reflects the maternal diet. This study aimed to identify volatile compounds in mother's milk and infant formula milks to obtain more knowledge about these sources of early sensory exposure in infant feeding. Mother's milk collected by ten lactating women, three times on three independent test days (n=90), and 11 different formula milks were examined. Formulas included seven milk-based liquid formulas and four powder formulas (one milk-based and three hypoallergenic). Both mother's milk and infant formulas were rich in lipid-derived volatile compounds including alcohols and carbonyl compounds. Formulas differed from mother's milk as they contained more volatiles related to thermal treatment such as methional, 2-furfural, and sulfides. By comparison, mother's milk revealed a higher variety of terpenes probably originating from the maternal diet. The number of identified volatiles in mother's milk varied both within samples obtained from the same woman and significantly between women. The latter one suggests large variety in breast-fed infants' exposure to volatiles. Qualitative differences existed for infant formulas. Powder forms revealed a greater number of compounds, predominantly secondary lipid oxidation products, and larger batch variations than liquid products. Extensively hydrolyzed formulas were significantly richer in volatile compounds associated with heat treatment of milk. These findings suggest that breast-fed infants are exposed to variations in volatile compounds in mother's milk, while formula-fed infants are exposed to less diverse flavors when fed infant formula from the same brand.

“…Recently, the pulsed flame photometric detector (PFPD), has started to be used for sulfur compounds (VazquezLandaverde, Torres, & Qian, 2006b). Recent work by Havemose, Justesen, Bredie, and Nielsen (2007) demonstrated that SPME is an appropriate method to study oxidative changes in milk but that it is not sensitive enough to detect compounds present at low concentrations, such as sulfur compounds. In our study, the SPME technique was used to analyze volatile compounds because the effect of high-pressure homogenization on milk fat globules will produce more oxidative than thermal changes.…”

“…A higher number of sulfurous components may be present in the milk sample than found by SPME-GC/MS, due to the fact that the human nose is much more sensitive to sulfurous components than the GC/MS (Senger-Emonnot et al, 2006). Moreover, extraction techniques like Solvent Assisted Flavor Evaporation (SAFE) will probably be more sensitive towards sulfurous components than SPME (Havemosea, Justesena, Bredieb, & Nielsen, 2006). SAFE is, however, not a simple and fast method for quality control.…”
