The fresh new prevalent resin acid is actually dehydroabietic acid and oxidization of the-facts regarding abietic acidic, also eight-oxodehydroabietic and you can hydroxy- 7-oxodehydroabietic acids Profile 5.
Temperature of the-things like retene had been in addition to noticeable. Methyl clermont base 63 recognition try within every examples and you can unmodified resin acids, abietic, pimaric and isoprimaric acids, were along with observed.
Much like the mountain trials, the about three resin acids just weren’t contained in all of the analysed trials, e. The lipid extractions provided small quantities of fatty acids. Only the saturated efas C and you will C was indeed found in the fresh new samples and have been characterized by an elevated or equivalent number regarding C versus C Data 5 and you can 6.
Such efficiency make sure the amphorae lining was made out of mountain while the presence regarding methyl dehydroabietate means, as stated a lot more than, it was brought straight from the fresh new temperature away from wood Colombini ainsi que al
Zero bush or creature sterols was basically observed in brand new samples. While the visibility of your acids isn’t a sign regarding certain belongings in this new amphorae, neither of incorporating off particular oils on their organic coatings. Plus tartaric acidic, most other substances which might be contained in wines have been along with contained in these products: malic, malonic, fumaric, succinic acids Table 2. In these instances, although it can not be definitively oriented one to wines try present in the new ships, they quality after that investigation.
To advance consider when your content is actually wines, more sampling http://www.datingranking.net/nl/mobifriends-overzicht methods and perhaps most other measures might possibly be checked-out when you look at the the long run. One another examples SN02 and you will SN07 was indeed regarding excavation on Cadiz and you can products was taken from the brand new motorboat necks.
Zero efas except that C and you will C was basically identified. Syringic acid and you can vanillic acid was indeed recognized both in products.
Syringic acid is considered to be several other biomarker of grape situations, produced from malvidin malvidin- 3-glucosidethe predominant anthocyanin the brand new pigment responsible for color from red grapes Singleton, ; Guasch- of lipid removal out-of Keay Contour six – Partial total ion chromatogram of the lipid removal of Keay Dining table 2 – Dominant compounds noticed in the wine biomarker extractions out-of Keay Additionally, as Barnard ainsi que al.
On samples clermont base 63 detection, syringic acidic is actually from the vanillic acidic and you may vanillin. This might suggest that in this case that isn’t relevant toward exposure regarding wine however, in order to something else. It is of interest to notice you to inside the examples regarding the necks out-of ships, like the several Keay In all cuatro neck products, syringic acidic is identified. Particularly, totally free syringic acid is located in particular bush present, and additionally inside the a small amount when you look at the lignin.
Therefore it is likely that the fresh new syringic acid throughout the trials is inspired by some other resource eg cork stoppers one phorae. Two of the cuatro lipid extractions did not indicate detectable greasy acids apart from prominent non-symptomatic efas i. C and you may C with no plant otherwise animal sterols was identified.
Like the most other amphora systems assessed, new Keay Pinaceae factors, particularly dehydroabietic acidic, methyl dehydroabietate and you will seven-oxodeydroabietic acids, was in fact and recognized in products, appearing a slope lining. Each other products contained significant amounts of C Cholesterol and you will cholesterol levels oxidation affairs was basically and seen in both trials. Cholesterol try an effective signal of a pet origin for the stuff. Decisive biomarkers out-of marine organisms, including isoprenoid efas, just weren’t seen in the fresh new samples off both vessels.
The brand new lipid analyses of products revealed mountain residues acquiesced by the clear presence of dehydroabietic acidic and you will eight-oxodehydroabietic acidic
The presence of such fatty acids and cholesterol levels will be the result often out-of a pet content maybe fish? Regarding the wines biomarker extractions of your own Keay Specific ingredients one to are located within the drink, besides tartaric acid, was basically found in the latest products: malic, succinic and you can fuples Table 2.
