The complex molecular assemblages were analysed in the soil gas phase after applying pine forest wastes (PFW) or sugarbeet vinasses (SBV) for soil-borne crop pests' management. For this purpose, solid-phase micro-extraction (SPME) and gas chromatography (GC) were used coupled with mass spectrometry (MS). The organic wastes were applied either to Calcic Entisol or Haplic Arenosol moistened at fi...

TiH distribution of sulphur in protein has long been a subject of interest, and the work of Osborne and numerous other investigators on the sulphur in vegetable proteins indicated the probable presence of at least two forms of organic sulphur; further, Dakin [1920] in his amino-acid analysis of gelatin found sulphur compounds other than cystine. The isolation of methionine [Mueller, 1921] and i...

Effects of four cooking methods (microwave cooking, grilling, steaming and shallow fat frying) and reheating by microwave on volatile profile in S. commerson were evaluated. Thirty compounds were identified in GC-MS analysis of raw samples. The number of volatile compounds had increased to 36, 46, 45 and 45 compounds in microwave cooked, grilled, steamed and shallow fat fried samples, respectiv...

As one of the most common solid wastes, municipal sewage sludge needs to be dried before its disposal and resource reuse. In this study, effects vacuum degree, heat source temperature thickness on drying rate odor concentration in tail gas were studied through orthogonal experiments carried out lab-scale heat-conductive device; The comparative atmospheric state (-0.08MPa). results show that is ...

The influence of two yeast strains and the addition copper sulphate on aroma Riesling wines was monitored. Two commercially available strains, Zymaflore VL3 X-Pure, were applied. General composition, volatile thiols, norisoprenoids, free terpenes, fermentation, sulphur compounds content determined, sensory attributes assessed by 22 tasters in a balanced incomplete block design (BIBD). produced ...

Abstract Mango stem bark extracts (MSBE) have been used as bioactive ingredients for nutraceutical, cosmeceutical, and pharmaceutical formulations due to their antioxidant, anti-inflammatory, analgesic effects. We performed the MSBE preparative column liquid chromatography, which led resolution identification by GC-MS of 64 volatile compounds: 7 hydrocarbons, 3 alcohols, 1 ether, aldehydes/keto...
