Keay The latest immersed mountain deposits drill a robust resemblance on obvious mountain samples

The fresh new predominant resin acid was dehydroabietic acid and you can oxidization from the-activities regarding abietic acidic, together with seven-oxodehydroabietic and hydroxy- 7-oxodehydroabietic acids Figure 5.

Temperatures of the-items such retene were and additionally obvious. Methyl clermont feet 63 identification try present in every trials and unmodified resin acids, abietic, pimaric and you can isoprimaric acids, was as well as observed.

Just like the mountain examples, all around three resin acids just weren’t within most of the analysed samples, e. New lipid extractions given small amounts of efas. Precisely the soaked essential fatty acids C and you can C was basically seen in the fresh new examples and you can was described as a heightened otherwise equal count regarding C versus C Rates 5 and you will six.

This type of performance confirm that brand new amphorae liner was created off pitch in addition to presence away from methyl dehydroabietate means, as stated more than, that it was introduced straight from the new temperatures out-of wood Colombini ainsi que al

Zero bush otherwise creature sterols had been present in the latest examples. As well as the presence of your own acids is not indicative regarding particular items in new amphorae, nor of the incorporating of certain oils to their natural coatings. Including tartaric acidic, almost every other compounds which can be within drink had been as well as contained in such samples: malic, malonic, fumaric, succinic acids Desk dos. In these cases, though it can not be definitively founded you to wine try contained in the fresh vessels, it merit subsequent investigation.

To help expand have a look at whether your posts is wines, some other sampling strategies and maybe other strategies was tested from inside the the near future. Each other examples SN02 and you will SN07 was from the excavation on Cadiz and products was indeed obtained from the latest motorboat necks.

Zero fatty acids besides C and you will C have been known. Syringic acidic and you may vanillic acidic had been understood both in products.

Syringic acidic is considered to be other biomarker off grape points, produced by malvidin malvidin- 3-glucosidethe commonplace anthocyanin the fresh new pigment accountable for color regarding red grapes Singleton, ; Guasch- of lipid removal off Keay Figure 6 – Partial full ion chromatogram of one’s lipid removal away from Keay Desk 2 – Dominant compounds present in the wine biomarker extractions from Keay More over, as the Barnard et al.

Throughout the products clermont ft 63 recognition, syringic acidic is from the vanillic acid and you may vanillin. This may advise that in this instance this is simply not associated into visibility off wine however, so you can something different. It’s interesting to remember one into the products in the necks off vessels, like the a couple Keay In every cuatro shoulder samples, syringic acid is known. In particular, totally free syringic acidic is found in certain plant provide, along with for the smaller amounts in the lignin.

Therefore it is possible that this new syringic acid on the products is inspired by various other resource instance cork stoppers one to phorae. Two of the 4 lipid extractions don’t imply noticeable fatty acids other than common non-symptomatic essential fatty acids we. C and C no bush otherwise animal sterols had been identified.

Like the almost every other amphora designs reviewed, the brand new Keay Pinaceae things, like dehydroabietic acid, methyl dehydroabietate and you will 7-oxodeydroabietic acids, were also recognized both in trials, exhibiting a slope lining. One another trials contains high amounts of C Cholesterol and you may cholesterol oxidation circumstances was and additionally perceived in both products. Cholesterol is actually a strong indication away from an animal origin for the newest posts. Definitive biomarkers off marine bacteria, such as isoprenoid essential fatty acids, just weren’t noticed in the brand new trials away from either ships.

The brand new lipid analyses of your own products shown slope deposits acknowledged by the existence of dehydroabietic acid and you may seven-oxodehydroabietic acidic

The presence of such essential fatty acids and you can cholesterol levels could be the result sometimes from an animal blogs perhaps seafood? About wines biomarker extractions of Keay Specific ingredients you to are observed during the wine, other than tartaric acid, were observed in new trials: malic, succinic and you may fuples Dining table dos.
