Some yeasts are involved in flavour development of dry-cured meat products showing a positive impact on the generation of volatile compounds. The aim of this work was to design a method of routine analysis to evaluate the production of volatile compounds by yeasts to be selected as starter cultures. For this purpose, several variations of a minimum culture medium that included free amino acids, oleic acid, and α-ketoglutarate, incubated under similar conditions of water activity and pH as dry-cured meat products, were assayed. In these conditions, the representative yeast strains isolated from a dry-cured meat product were tested. The volatile compounds were analysed using Solid Phase Micro-Extraction and gas chromatography/mass spectrometry. In the designed media, the tested yeasts produced volatile compounds involved in flavour development of dry-cured meat products. In addition, all the strains showed the highest production of these volatile compounds in the complete minimum culture medium witch included α-ketoglutarate and oleic acid.

Abstract Using a range of chromatographic, spectroscopic, and mass spectrometric analytical techniques, we characterized one of the “edible items” found at the Vesuvius archeological sites and guarded at the National Archaeological Museum of Naples (MANN) in Naples, Italy. We authenticated the specimen contained in a glass bottle (Mann-S1 sample) as originally olive oil and mapped the deep evolution throughout its 2000 years of storage. Triacylglycerols were completely hydrolyzed, while the resulting (hydroxy) fatty acids had partly condensed into rarely found estolides. A complex pattern of volatile compounds arose mainly from breakdown of oleic acid. With excellent approximation, radiocarbon dating placed the find at the time of the Plinian Mount Vesuvius eruption in 79 A.D., indicating that Mann-S1 is probably the oldest residue of olive oil in the world found in bulk amount (nearly 0.7 L).

Allanblackia floribunda seed is one of the underutilized and under-exploited seeds in Nigeria, it is a flowering plant in the clusiaceae family that has been used over the years in folk medicine especially in managing hypertension in Africa. This study seeks to evaluate the phytoconstituents of Allanblackia floribunda. Qualitative phytochemical screening, proximate analysis and volatile compounds present in the seeds were evaluated using standard methods. The phytochemical screening showed the presence of alkaloids, flavonoids, tannins, triterpenoids and saponins in the seeds. The result from the proximate compositions showed that the seed had high fibre (4.21%), lipid (10.46%), protein (19.25%), and carbohydrate (61.26%) contents. The GCMS result revealed the presence of compounds with medicinal and nutritional potentials, among these compounds are caryophyllene (13.228%) and oleic acid (2.021%). This study revealed that an Allanblackia floribunda seed has phytoconstituent with nutritional and medicinal importance.
