The key aroma components and the lipolysis in a dry cured sausage 'Sobrassada of Mallorca from black pig' were studied. Sobrassada was characterized by a fatty acid profile with a high content of monounsaturated fatty acids and by the generation during the curing process of polyunsaturated free fatty acids that were oxidized to generate flavor compounds. Eighty-four different volatile compounds...

Engineering dual-function single polypeptide catalysts with two abiotic or biotic catalytic entities (or combinations of both) supporting cascade reactions is becoming an important area enzyme engineering and catalysis. Here we present the development a PluriZyme , TR 2 E efficient native transaminase ( k cat : 69.49±1.77 min -1 ) artificial esterase 3908 to 0.41 activities, integrated into sca...

In today's society, the risk of cardiovascular disease is steadily rising. The fatty acid composition three local fermented food condiments (dawadawa, ogiri igbo, and okpei) purchased from different markets in Aba, Nigeria, was studied using gas chromatography mass spectrometry (GCMS) order to look for alternative natural that are absorbed body without having many health implications. profiles ...

Most air quality studies in agricultural environments use thermal desorption analysis for quantifying semivolatile organic compounds (SVOCs) associated with odor. The objective of this study was to develop a robust sampling technique for measuring SVOCs in humid environments. Test atmospheres were generated at ambient temperatures (23 +/- 1.5 degrees C) and 25, 50, and 80% relative humidity (RH...

A strictly anaerobic, Gram-stain-positive bacterium, designated FW431T, was isolated from a mud cellar used for producing strong aromatic Chinese liquors. The strain was able to produce butanoic acid, an important component of the aroma style of Chinese liquors. Cells of strain FW431T were straight or slightly curved rods with a polar endospore and peritrichous flagella. The major cellular fatt...

In the ®rst of the title compounds, (2S)-2-(1-oxo-1H-2,3dihydroisoindol-2-yl)pentanoic acid, C13H15NO3, prepared from l-norvaline, a hydrogen-bonded network is formed in the solid state through OÐH O C, CÐH O C and CÐ H arene intermolecular interactions, with shortest O O, C O and C centroid distances of 2.582 (13), 3.231 (11) and 3.466 (3) AÊ , respectively. In the l-valine derivative, (2S)-3m...

A set of novel series of 1,3,4-thiadiazolyl-sulfanyl-4,5-dihydropyridazin-3(2H)-ones with anticipated antimicrobial activity has been synthesized. The synthetic protocol of the targeted compounds was accomplished by treating β-aroylacrylic acid 1 with 5-amino-1,3,4-thiadiazole-2-thiol (2) to afford the thia-Michael adduct 3. Afterwards, the obtained thia-Michael adduct 3 was cyclized to 4,5-dih...

Chemoreception is a key feature in selection of host plant by phytophagous insects, and odorant-binding proteins (OBPs) are involved in chemical communication of both insects and vertebrates. The legume pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae) is one of the key pest species of cowpea and widely distributed throughout tropical and subtropical regions, causing up to 80% of yie...
