New common resin acid try dehydroabietic acidic and you can oxidization because of the-things regarding abietic acidic, together with eight-oxodehydroabietic and you can hydroxy- 7-oxodehydroabietic acids Figure 5.
Heat by the-things such as for instance retene was in fact along with apparent. Methyl clermont feet 63 detection was found in all the examples and you will unmodified resin acids, abietic, pimaric and you can isoprimaric acids, were including noticed.
Similar to the mountain products, the three resin acids just weren’t contained in all of the analysed products, elizabeth. The newest lipid extractions considering small amounts of efas. Just the over loaded fatty acids C and you can C was found in this new products and were characterized by an elevated or equal count out-of C as compared to C Data 5 and you may 6.
These overall performance confirm that this new amphorae liner was made away from pitch while the presence regarding methyl dehydroabietate ways, as mentioned more than, it absolutely was lead directly from brand new heating regarding wood Colombini ainsi que al
Zero bush or creature sterols have been seen in the new trials. While the exposure of your acids isn’t an indication out of particular items in brand new amphorae, nor of the adding out-of specific fats on their natural coatings. And tartaric acid, other ingredients that will be within wines was basically together with contained in this type of examples: malic, malonic, fumaric, succinic acids Dining table 2. In these cases, although it cannot be definitively based you to drink is within the latest ships, they merit after that research.
To help glance at in the event the posts is wine, additional testing strategies and maybe other measures will be tested when you look at the the long run. Both samples SN02 and SN07 was regarding the excavation during the Cadiz and you can examples were obtained from the new motorboat necks.
Zero fatty acids other than C and C had been understood. Syringic acidic and you may vanillic acid was in fact recognized in examples.
Syringic acid is recognized as being various other biomarker away from grape items, based on malvidin malvidin- 3-glucosidethe widespread anthocyanin this new pigment accountable for coloration of grapes Singleton, ; Guasch- of one’s lipid removal out-of Keay Contour 6 – Limited overall ion chromatogram of your lipid removal off Keay Table 2 – Prominent ingredients present in the wine biomarker extractions away from Keay Additionally, because the Barnard ainsi que https://datingranking.net/nl/senior-match-overzicht/ al.
In the trials clermont legs 63 recognition, syringic acidic was in the vanillic acidic and you will vanillin. This may recommend that in this case this is simply not relevant into visibility away from wines however, so you’re able to something else entirely. It is interesting to see one into the trials from the necks out of boats, like the two Keay In all 4 neck examples, syringic acid is actually recognized. Particularly, 100 % free syringic acidic is found in some plant provide, together with into the small amounts inside lignin.
So it is possible that the newest syringic acidic about examples comes from some other provider particularly cork stoppers you to phorae. A couple of cuatro lipid extractions didn’t imply noticeable greasy acids except that popular non-diagnostic efas i. C and C without plant or creature sterols were recognized.
Like the most other amphora models assessed, the fresh Keay Pinaceae circumstances, eg dehydroabietic acid, methyl dehydroabietate and you may 7-oxodeydroabietic acids, have been and additionally recognized in examples, appearing a slope lining. Each other trials consisted of tall degrees of C Cholesterol and you can cholesterol oxidation points was along with sensed in both trials. Cholesterol levels is actually a powerful sign from an animal origin for the articles. Decisive biomarkers away from aquatic organisms, instance isoprenoid essential fatty acids, were not noticed in the fresh products regarding possibly ships.
This new lipid analyses of one’s samples revealed slope deposits acknowledged by the existence of dehydroabietic acidic and you will 7-oxodehydroabietic acid
The current presence of these types of essential fatty acids and you may cholesterol could be the influence either out-of a pet articles maybe seafood? From the drink biomarker extractions of Keay Specific ingredients one to are found for the wine, apart from tartaric acid, was basically observed in the fresh trials: malic, succinic and you will fuples Dining table 2.
