Marker Substances in the Aroma of Truffles<\/a><\/strong><\/p>\nAbstract<\/em>
\nThe aim of this study was to identify specific truffle marker substances within the truffle aroma. The aroma profile of different truffle species was analyzed using static headspace sampling with gas chromatography mass spectrometry analysis (SHS\/GC-MS). Possible marker substances were identified, taking the additional literature into account. The selected marker substances were tested in an experiment with 19 truffle dogs. The hypothesis \u201cIf trained truffle dogs recognize the substances as supposed truffles in the context of an experiment, they can be regarded as specific\u201d was made. As it would be nearly impossible to investigate every other possible emitter of the same compounds to determine their specificity, this hypothesis was a reasonable approximation. We were interested in the question of what it is the dogs actually search for on a chemical level and whether we can link their ability to find truffles to one or more specific marker substances. The results of the dog experiment are not as unambiguous as could have been expected based on the SHS\/GC-MS measurements. Presumably, the truffle aroma is mainly characterized and perceived by dogs by dimethyl sulfide and dimethyl disulfide. However, as dogs are living beings and not analytical instruments, it seems unavoidable that one must live with some degree of uncertainty regarding these results.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_genesis_hide_title":false,"_genesis_hide_breadcrumbs":false,"_genesis_hide_singular_image":false,"_genesis_hide_footer_widgets":false,"_genesis_custom_body_class":"","_genesis_custom_post_class":"","_genesis_layout":"","footnotes":""},"categories":[189,500],"tags":[389,406,408,553,550,554],"class_list":{"0":"post-10882","1":"post","2":"type-post","3":"status-publish","4":"format-standard","6":"category-investigacion-es","7":"category-publications-es","8":"tag-customized-es","9":"tag-fluorescence-es","10":"tag-gap-es","11":"tag-irradiance_lo-es","12":"tag-science-es","13":"tag-truffles-es","14":"entry"},"acf":[],"yoast_head":"\n2022 - Marker Substances in the Aroma of Truffles | sglux<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/sglux.de\/es\/2022-marker-substances-in-the-aroma-of-truffles\/\" \/>\n<meta property=\"og:locale\" content=\"es_ES\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"2022 - Marker Substances in the Aroma of Truffles | sglux\" \/>\n<meta property=\"og:description\" content=\"Ruben Epping\u00b9, Lilly Bliesener\u00b9, Dr. Tilman Weiss\u00b2, Matthias Koch\u00b9, * \u00b9Division of Organic Trace Analysis and Food Analysis, Bundesanstalt f\u00fcr Materialforschung und -Pr\u00fcfung, Berlin, Germany \u00b2sglux GmbH, Berlin, Germany *Authors to whom correspondence should be addressed.
