IMPROVED INFANT FORMULA CONTAINING AN AROMA COMPOSITION FOR USE AS FRAGRANCE

Description

[0001] Breast-feeding is believed to exhibit a series of advantages for the newborn compared to bottle-feeding. Human milk has been shown to impart several nutritional and health benefits, for example promotion of the infant's neuronal and intestinal development and fortification of the immune system 1, 2, 3. Apart from these aspects, many studies point out that human milk exhibits certain olfactory clues that foster the newborns' ability to orient themselves versus the human milk source 4, 5, 6, and that might even play an important role in the development of certain food preferences in later life 7, 8, 9, 10. Moreover, newborns are able to distinguish between human milk and cow's or artificial milk, they can separate between their own mother's milk and that of other women, and are even able to distinguish between different types of human milk according to their individual temporal needs, that means between e.g. colostrum and mature human milk 4, 6, 11, 12. Even more interesting is that it was shown in these studies that babies prefer the odor attributes of human milk compared to those of artificial infant formula or milk products based on milk compositions of animal origin such as cow's milk etc. To date, most studies in the area of milk research dealt with the characterization of odor-active volatiles in processed animal milks, predominantly UHT or pasteurized milks 13, 14. From these, the conspecific odor compositions of the milks from for example cows, ewes, etc. cannot be deduced as odorants might be degraded during the heating and further processing steps, or might be formed as new and additional odor constituents. Several effects forming artificial non-natural flavor attributes in milk have been well-documented such as the sunlight-flavor etc. 13, 14.

[0002] On the other hand, there are some studies dealing with the identification and quantification of conspecific volatiles or odorants in fresh or raw animal milk 14. However, most of these studies are based on techniques such as gas chromatographic and mass spectrometric methodologies that do not allow any weighting of a possible sensory contribution of the respective compounds 15. Only a few studies targeted at the identification of odor-active substances in animal milk such as water buffalo and ewe's milk 16, 17, 18, 19. Among the most common volatiles were aldehydes, ketones, esters, lactones and several diverse substances such as terpenes and aromatic compounds.

[0003] Also, as for human milk, the influence of mother's diet on the milk odor profile compositions is not yet understood. For cow's milk and ewe's milk, there are a few studies characterizing the changes of milk odor profiles with regard to specific feeding regimes, but in most cases just on a sensory, not on a chemical-analytical basis 19, 20, 21.

[0004] While there is numerous evidence on the psychophysics level that human milk displays a very characteristic and individual olfactory composition, the molecular principles behind these phenomena remained relatively unclear. This was predominantly due to the fact that, on the one hand, sample size is very limited for comprehensive investigation of the odor composition and of the odor-dynamics of human milk in relation to single breastfeeding episodes. On the other hand, the commonly used techniques for odor analysis of human milk such as solvent extraction techniques or gas chromatographic analysis in coupling with mass spectrometry or flame ionization detection were very limited with regard to odor specificity.

[0005] This might be regarded as the main reason that only limited data on the chemical characterization of odor-active compounds in human milk is available to date 22. In this cited study, authors succeeded in identifying a total of five odorants which were detectable in all four analyzed breast milk samples. These compounds were the fatty-tallowy smelling (E)non-2-enal, the mushroom-like smelling oct-1-en-3-one, the caramel-like compounds 4-hydroxy-2,5-dimethyl-3(2H)-furanone and maltol, and the milky smelling 2-nonanone. All of these compounds were also detectable in formula milk. On the other hand, some additional compounds were identified in formula milk: the buttery smelling butane-2,3-dione, the cooked potato-like smelling 3-methylthio propanal (methional) and the meat-like smelling 2-methyl-3-furanthiol. In conclusion, no human milk-specific compound has been reported in this study. A second study reported a series of volatiles in human milk, with 6 esters, 13 ketones, 6 fatty acids, 2 lactones, 24 aliphatic aldehydes, 9 alcohols, 18 hydrocarbons, and 6 miscellaneous compounds 23. Authors used an isolation procedure based on simultaneous steam distillation-extraction under reduced pressure using diethyl ether as the solvent with a distillation temperature of 62 to 65 °C during two hours of extraction. Detection and identification of the volatile compounds was accomplished by means of gas chromatography combined with mass spectrometry based on comparison of mass spectral data with library MS spectra. However, in the cited study, the sensory properties and the sensory contribution or impact of the identified compounds with regard to human milk was not elucidated. Moreover, the list of detected volatiles comprises a series of substances which are, to the specialist of the field of odor research, highly unlikely to be odor-active contributors of human milk, for example toluene, n-propylbenzene, 1,2,4-trimethylbenzene, m-, p- and o-ethyltoluene, 1H-pyrrole, N-butyl-N-nitrosobutanamine, N,N-dibutylformamide etc. Identification of such volatiles is more likely to be produced either by artefacts, by drawbacks of the analytical outline (identification by comparison with mass spectra library data only) or by environmental contaminations of the human milk as it has been described in different aspects 24, 25. In conclusion, it seems highly improbable that these substances are natural human milk odor constituents that are supposed to compose the human milk aroma attributes. This is supported by the aspect that there are no common biochemical routes known that would explain the occurrence of such substances in human milk as endogenous compounds. In addition, it is not clear whether some of the given volatiles have been generated due to the thermal treatment during the analytical procedure as specified above, or have been destroyed. Therefore, it is not possible to identify potential odor contributors for human milk aroma among the identified volatiles presented in the cited study, and to rate their possible impact and contribution to human milk aroma.

[0006] So far the addition of natural odorants of human milk for improving the acceptance of nutraceutical compositions has not been described.

[0008] Giammarioli S. et al.: "Determination of hexanal in infant formulas by headspace-gas chromatography", Italian Journal of Food Science (1995) describes a headspace-GC method for quantitative determination of hexanal in infant formulas.

[0009] DE 2057906 discloses a method for the preparation of baby food which contains acetic acid.

[0010] EP 1 728 496 A2 describes a method for feeding an infant, a feeding device, a pacifying device and an odour carrier.

[0011] The international application WO 99/37270 refers to an olfactory stimulus for eating, a method to increase a user's intake of a novel diet, a method to stimulate overall ingestion for babies and a method to stimulate an ingestion of breast milk.

[0012] WO 97/30687discloses a fragrance precursor composition, a compound of formula A-OR¹, a process for prolonging the effect of diffusion, a method of suppressing human body malodour and the use of a compound.

[0013] US 2005/0261738 describes a simulated breast comfort aid system.

[0014] In order to find an optimal infant formula, wherein the amounts and composition of the odor-active substances are as dose as possible to mother's milk, the present inventor has studied the odor composition of fresh human milk by appropriate analytical tools without thermal exposition, predominantly taking into account the aspect of odor-activity. The analytical approach comprising gas chromatographic-olfactometric characterization of the odor volatiles was used that allowed the unambiguous identification of odor-active compounds even in small-scale human milk samples.

[0015] This approach offers the possibility to analyze milk from individual donors with minimal disturbance of the normal breast feeding procedure, and without the need to pool samples from a number of donors, as it was done in other studies. Also, the technique allows the analysis of separate individual milk sample portions from within one feeding session. That means the target was to develop an approach that allowed collection of a small portion of milk right at the beginning of the feeding episode, followed by one or more additional sampling events later on during the same feeding episode.

[0016] To achieve this goal, a very versatile and sensitive extraction technique for gaseous and liquid samples, the stir bar sorptive extraction (SBSE) was used 26. In SBSE, a PDMS-coated stir bar is exposed for a certain extraction time to a certain volume of sample either with or without preliminary application of derivatization techniques. After sorption of the analytes into the PDMS material, and removal of the matrix system, the analytes can be easily recovered via solvent extraction or thermo-desorption, and analyzed for example by means of high resolution-gas chromatography or liquid chromatography in combination with the respective detector systems. Compared to other sorptive sample preparation techniques such as SPME, the SBSE has several advantages such as convenient handling, high extraction capacity, very low amounts of PDMS breakdown products and many more 27. Apart from environmental investigations such as pesticide analysis and several others 27, 28, 29, first applications of SBSE have been reported for the direct analysis of e.g. benzoic acid or dicarboximide fungicides in foods and beverages 30, 31, for the elucidation of biochemical pathways, and for the analysis of odorous compounds in foods, mainly liquids 33, 34, 35. Combination with multidimensional gas chromatography using chiral chromatography systems allowed the assignment of the stereochemistry of aroma compounds in foods such as strawberries 36. In-vitro studies of biological markers, drugs, their metabolites or other artificial contaminants such as PCBs have been just recently performed on body fluids such as sperm, blood and urine 37, 38. Recently, SBSE was used in the context of a new in-vivo approach called BOSS (Buccal Odor Screening System) 39, 40. It was successfully applied for the characterization of volatile coffee and wine aroma "aftertaste" substances within the oral cavity. A variation of the system was applied to monitor the development of breath odor profiles after consumption of beer 43. The use in milk has not been described. An adopted approach for characterization of human milk odorants will be presented in the following.

[0017] Trace volatile and odorous substances that were characterized in fresh human milk with regard to their molecular composition and their sensory characteristics. The methodology was successfully applied for identification of more than forty characteristic odorants in human milk. The technique comprises a modified stir bar sorptive extraction system in combination with two-dimensional gas chromatographic separation and parallel mass spectrometric and olfactometric characterization of the analytes. The present invention shows that the technique can be used both for direct extractive sampling, but also for headspace analysis. Due to its applicability for small sample volumes, even day-to-day physiological variations in the profiles of volatile organic compounds in human milk samples, but also fluctuations within e.g. one breastfeeding episode can be monitored.

[0018] Accordingly, the object of the present invention is to provide nutraceutical compositions that are more attractive for babies and newborns.

SUMMARY OF THE INVENTION

The following compounds were synthesized according to the literature trans-4,5-epoxy-(E)-2-decenal (Schieberle P, Grosch W.Z. Lebensm. Unters. Forsch. 1991, 192: 130-135),1-hexen-3-one (Blank I, Fischer KH, Grosch W. Z. Lebensm. Unters. Forsch. 1989, 189: 426-433), (Z)-octa-1,5-dien-3-one (Ulrich F, Grosch W. J. Am. Oil Chem. Soc. 1988, 65: 1313-1317), (Z)-non-2-enal (Ullrich F, Grosch W. Fat Sci. Technol. 1988, 90:332-336), 4-ethyloctanoic acid (Rota V. Charakterisierung von Schlüsselaromastoffen in rohem und gekochtem Schaffleisch durch Anwendung von Struktur/Wirkungskonzepten. PhD thesis, Technical University Munich, Germany, Verlag Dr. Hut, Muenchen, Germany, 2004). The compounds were freshly distilled prior to analysis. Chemical and sensory purity was checked by gas chromatography-olfactometry (GC/O) as well as gas chromatography-mass spectrometry (GC-MS).

Samples

[0079] Ten samples of human milk were collected from different donors and immediately stored for a maximum of two days prior to analysis at -18°C. Panelists were non-pregnant volunteers (non-smokers, Germans of Caucasian ethnicity) in the age range 28-35 (mean age 32), exhibiting no known illnesses at the time of examination. Breast milk production was normal and no breast infection was detected prior to milk sampling. Sampling took place in the lactation period from 12 to 20 weeks postpartum. 20 mL samples were taken during the day, about 1-2 hours after a light meal that was relatively weak in odor (water, plain bread with little amounts of butter and cottage cheese), right before a regular breast feeding episode. Prior to sample collection and analysis, written consent has been obtained from all participants providing human milk samples after full explanation of the purpose and nature of the study.

PDMS-coated Stir Bars

[0080] For the experiments, commercially available Twister®-SBSE bars (20 mm length, 0.5 mm POMS coating thickness and ~50 µL of total POMS volume according to the suppliers specifications; Gerstel GmbH, Mühlheim a/d Ruhr, Germany) were used. Prior to analysis, the bars were subjected to a conditioning procedure according to the suppliers recommendations: the stir bars were first soaked in 100% acetonitrile for at least two days, then conditioned at 300°C for 4h.

[0081] Each SBSE bar was first screened for odorants ("background", see "Results and Discussion") and then directly used for analysis. Each stir bar was used for just one single experiment, then reconditioned and screened for background again. Each experiment was performed with at least three different SBSE bars to avoid SBSE bar variations.

Direct StirBar Sorptive Extraction of Human Milk Samples

[0082] Five mL of each human milk sample were pipetted separately into 10 mL closed glass vessels and tightly sealed with a lid (cf. Figure 1). Glass vessels had been thoroughly cleaned prior to analysis and heat-conditioned at 110°C to avoid any odorous contamination. A SBSE bar was immediately placed in the respective sample, stirred for 1h, removed with tweezers, dipped into deodorized water, briefly dried with lint-free tissue and immediately placed into the thermo-desorption unit.

Headspace Sampling

[0083] Five mL of each human milk sample were pipetted separately into 10.mL closed glass vessels, affixed with inserts for headspace exposition of the PDMS stir bar, and tightly sealed with a lid (cf. Figure 1). Glass vessels had been thoroughly cleaned prior to analysis and heat-conditioned at 110°C to avoid any odorous contamination. Equilibration of the SBSE bar within the headspace insert above the stirred sample was conducted for 1h. Then, the SBSE bar was removed with tweezers, dipped into deodorized water, briefly dried with lint-free tissue and immediately placed into the thermo-desorption unit.

SBSE Thermo-Desorptive Sample Application

[0084] Thermo-desorption of the samples was performed by means of a TDS-2 thermo-desorption system (Gerstel GmbH) in combination with a CIS-4 PTV injector (Gerstel GmbH) for cryofocussing the analytes prior to transfer onto the analytical column. The following sampling parameters were used: Splitless thermal desorption was performed by programming the TDS-2 from 40°C to 240°C (5 min) at a rate of 60°C. Cryofocussing was performed with liquid nitrogen at -100°C. Injection was performed with a ramp of 12 °C/s from -100°C to 240°C (5 min). The gas chromatographic conditions are given below.

High Resolution Gas Chromatography-Olfactometry

[0085] Application of the samples was performed as described above (SBSE Thermo-Desorptive Sample Application). The odorants were screened in parallel by three panelists by sniffing the effluent after gas chromatographic separation. Sniffing analysis was repeated three times by each panelist. All detected odorants were identified by comparison with reference substances on the basis of the following criteria: retention index (RI) on two stationary phases of different polarity (DB-FFAP, DB-5), mass spectra obtained by MS (EI) and MS (CI), and odor quality as well as odor intensity perceived at the sniffing-port. Only if the odor quality and intensity of the reference agrees with that detected via GC-O, identification can be regarded as "positive".

[0086] The one- (for sniffing) or two-dimensional (for mass spectrometric identification) gas chromatographic system (TD-HRGC) consisted of a Mega 2 gas chromatograph (Fisons Instruments, Mainz-Kastel, Germany) as the precolumn system in tandem with a Fisons GC 5160 as the main column system (cf. Figure 2). The following fused silica columns were used: DB-FFAP (30 m x 0.32 mm i.d., 0.25 µm FD, J & W Scientific, Folsom, USA) and/or DB-5 (SE-54; 30 m x 0.32 mm i.d., 0.25 µm FD, J & W Scientific, Folsom, USA). The gas chromatographic conditions were the same as described previously.

High Resolution Gas Chromatography-Mass Spectrometry

[0087] The odorants were analyzed by two-dimensional gas chromatography (TD-HRGC) as described above. MS analyses were performed in parallels with the sniffing analysis on the main column system with an ITD-800 (Fisons Instruments, Mainz-Kastel, Germany) running in the CI-mode with methanol as the reagent gas. The following fused silica columns were used: DB-FFAP (30 m x 0.32 mm i.d., 0.25 µm FD, J & W Scientific, Folsom, USA) in combination with DB-5 (SE-54; 30 m x 0.32 mm i.d., 0.25 µm FD, J & W Scientific, Folsom, USA). The gas chromatographic and mass spectrometric conditions were the same as described previously.

Characterization Odor-active Compounds via PDMS Bar - Headspace Sampling

[0088] When analyzing the headspace above the human milk samples by means of HRGC-olfactometry of the adsorbed substances, a total of 22 odor-active compounds was detected.

[0089] Twenty-one of these were identified based on the criteria given in the experimental section (cf. Table 2). Among the detected compounds were aseries of fatty smelling compounds, (E)-oct-2-enal, (Z)-non-2-enal, (E)-non-2-enal, (E,E)-nona-2,4-dienal, grassy, leaf-like and citrussy substances (hexanal, octanal), and several coconut-like smelling compounds of the lactone group, that is γ-nonalactone, γ-decalactone, and δ-decalaetone. Acidic and sweaty impressions were due to acetic acid and butanoic acid. Apart from that, several sweet substances were detectable, such as the honey-like smelling phenylacetic acid, as well as 4-hydroxy-2,5dimethyl-3(2H)-furanone (caramel-like) and vanillin (vanilla-like). Metallic, mushroom- and geranium leaf-like substances were hex-1-en-3-one, oct-1-en-3-one, (Z)-octa-1,5-dien-3-one and trans-(4,5)-epoxy-(E)-2-decenal and an unidentified geranium leaf-like smelling odorant.

[0090] Specific malty, buttery and cooked potato-like impressions were elicited by methylpropanal, diacetyl, and methional, respectively. With the exception of the unknown geranium leaf-like compound, all odorants were detectable in all milk samples from different donors (Table 1).

[0091] The chemical structures of these odorants are shown in Figures 3 and 4.

a The compounds were identified by comparing it with the reference odorant based on the following criteria: retention indices on the capillaries named in the table, mass spectra obtained by MS/EI and MS/CI, odor quality and intensity perceived at the sniffing port. b Odor quality perceived at the sniffing port. c Sampling technique: HS: HRGC-Olfactometric detection of odorants via PDMS bar - headspace sampling, SA: HRGC-Olfactometric detection of odorants via direct stir bar sorptive extraction of the milk sample. d Retention indices were calculated according to Halang WA, Langlais R, Kugler E. Anal. Chem. 1978, 50:1809-1832.

Characterization Odor-active Compounds via Direct Stir Bar Sorptive Extraction of Human Milk Samples

[0092] HRGC-olfactometric analysis of the adsorbed volatiles from direct extraction of human milk led to the identification of the same compounds discussed above (cf. Table 1). Apart from that, 25 additional compounds were detectable by means of HRGC-O. Only seven of these were detectable in all human milk samples from all donors: the peach-like smelling (Z)-6-γ-dodecenolactone, the fatty smelling (E,E)-deca-2,4-dienal, and the citrussy-soapy smelling compounds nonanal and decanal. Interestingly, the other three of these seven odorants elicited for adults relatively objectionable, animalic odors: the goat-like smelling 4-ethyloctanoic acid, an unidentified musty smelling odorant, as well as the urine-like smelling 5α-androst-16-en-3α-one.

[0093] Additional compounds were the faeces-like smelling 3-methylindole, the intensely sweaty 2-and 3-methylbutanoic acids and pentanoic acid, and an additional unidentified goat-like compound. These odorants were, however, not sensorically detectable in all milk samples. The remaining compounds were also not detectable in all milk samples, but only a few of them. These were the fatty and cucumber-like smelling odorants (E,E)-octa-2,4-dienal and (E,Z)-nona-2,6-dienal, and the mushroom-like smelling non-1-en-3-one. Other for adults relatively pleasant odor notes originated from the flowery compounds linalool and β-ionone, the sweet smelling 2-aminoacetophenone and δ-dodecalactone, and two honey-like odorants (phenylacetaldehyde and 2-phenylethanol). Characteristic bellpepper-like, phenolic and savory-like impressions were elicited by 3-isobutyl-2-methoxypyrazien, 2-methoxyphenol, and sotolon, while one metallic smelling compound remained unidentified.

[0094] In the present invention, a broad variety of odor-active substances was identified in human milk samples. It was shown that not only a large number of compounds can be found, but that these odorants are structurally very diverse, and exhibit an array of different olfactory impressions. It was also shown that most of these substances were detectable either by means of headspace analysis or by direct SBS extraction of the milk samples. For this reason these compounds are characteristic constituents of human milk.

[0095] Comparing the results presented here with those of Bingham et al. (Bingham PM, Stevens-Tuttle D, Lavin E, Acree T. Arch. Pediatr. Adolesc. Med. 2003, 157: 1031) who analyzed four breast milk samples, it can be seen that the fatty smelling (E)-non-2-enal, the mushroom-like smelling oct-1-en-3-one and the caramel-like smelling 4-hydroxy-2,5-dimethyl-3(2H)-furanone were in both studies among those compounds which were detectable in all milk samples. However, diacetyl and methional which were only found in formula milk in the previous study, were identified as human milk odorants in the present application, together with more than 30 additional odorants which had not been reported by Bingham et al.

[0096] More than 50% of these odorants were even detectable just in the headspace of the human milk samples, without the need for a direct milk extraction methodology. This displays the high sensitivity and selectivity of the applied analytical procedure. On the other hand, those compounds which were additionally detected by direct SBS extraction of the milk samples were odorants with relatively high molecular weight, such as 5α-androst-16-en-3α-one or (Z)-6-γ-dodecenolactone. Often they were homologues with higher molecular weights of related substances already detected by headspace analysis. For example, hexanal and octanal were identified by means of headspace analysis while nonanal and decanal were additionally found by the direct extraction procedure. This mirrors discrimination effects of the headspace technique due to volatility aspects, and highlights the need to use the direct extraction technique as complementary tool.

[0097] The detection of the steroid compound 5α-androst-16-en-3α-one as sensorically active constituent using the presented SBSE procedure is noteworthy. On the other hand, maltol and 2-nonanone were not detected in our study by means of HGRC-O after SBSE enrichment. It is difficult to speculate about the reasons for these differences as details on the exact experimental procedure have not been provided in the previous study (Bingham PM, Stevens-Tuttle D, Lavin E, Acree T. Arch. Pediatr. Adolesc. Med. 2003, 157: 1031). While it has been specified that analysis and identification had been performed by means of gas chromatography-olfactometry, and had also been based on the respective odorant retention indices, no details have been given on the mode of odorant enrichment or recovery. In this context, it needs to be stated that only those compounds were taken into consideration within the present invention which were detectable by means of HRGC-O, but not HRGC-FID or HRGC-MS only. This has obviously been done accordingly in the study by Bingham et al. Therefore, the detection differences are very likely due to the fact that another sample work-up procedure has been used, such as solvent extraction and/or a distillation approach.

[0098] Generally, it has to be noted that maltol and 2-nonanone are not very potent odorants. Comparison with previous results on SBSE application in the determination of trace aroma compounds in physiological context implies that this approach is a highly sensitive, and a useful complementary tool for identification of odorants in small-scale samples. This is affirmed by the present study with the first-time characterization of large number of human milk odorants. This shows that the applied technique can be used as a screening system for potent odorants in small-scale human milk samples. For selective and sensitive quantitation the presented technique can be used as basis for e.g. stable isotope dilution assays as described elsewhere.
