Volatile organic compounds in farmed and wild rohu, Labeo rohita, were extracted by Likens-Nickerson concurrent distillation apparatus. The farmed raised rohu of two weight categories designated as FW1 (1001-1200g) and FW2 (501-700g) were procured from the Fish Seed Hatchery, Faisalabad. Concurrently, wild rohu of two weight categories designated as WW1 (1001-1200g) and WW2 (501-700g) were capt...

The volatile constituents of the aerial parts of vervain (Verbena officinalis L.) cultivated locally were investigated. Analysis of the volatile fraction by GC and GC-MS is described. Compounds were identified by various methods, the major compounds being 3-hexen-1-ol (7.28%), 1-octen-3-ol (32.76%), linalool (4.66%), verbenone (20.49%) and geranial (7.22%).

This project has the objective to investigate the economic and technical perspectives for the replacement of woody biomass with non-woody biomass in a biomass gasification process. Non-woody biomass fuels like straw, manure and sludge are cheap fuels with an increased chlorine, sulphur and ash content. A representative biomass composition for non-woody biomass is 13 wt% ash, 0.3 wt% chlorine an...

in this study, the relationship among four species of polygonum (including p. hyrcanicum (three samples), p. persicaria, p. avicular, and p. hydropiper) was investigated by gc profiling. furthermore, the major compounds of the ethylic ether extract of p. hyrcanicum were identified by gc/ms as: α-bisabolol (17.5%), cedrol (15.9%), sesquisabinene hydrate (13.0%), α-elemol (10.5%) and trans-longip...

background and objective: reduced fat cheese often exhibits poor sensory quality due to the reduction of fat, which plays a critical role in flavor and texture. therefore, there is the challenge to produce a reduced fat cheese with improved sensory attributes and texture that is also comparable to its full-fat counterpart. the main objective of this research was to investigate the effect of dif...

The unique and delicate flavour of olive oil is attributed to the volatile compounds that develop during and after oil extraction from the olive fruit. The formation of these volatile compounds and the fruit characteristics that affect the formation are examined in this review. The role of extraction time -temperature interactions in volatile development and other factors that impact volatile d...

This study investigated the composition of volatile compounds in two pummelo cultivars, including 'Shatian' and 'Guanxi', cultivated in different regions of China with the aim of studying the effect of cultivar and cultivation condition on biosynthesis of volatile compounds in pummelo. Volatile compounds were extracted from pummelo juice using head-space microextraction and then analyzed using ...

BACKGROUND AND OBJECTIVE Volatile sulfur compounds may be the main source of oral malodor. The aim of this study was to clarify the relationship between periodontal parameters and volatile sulfur compounds and to evaluate the improvement of several halitosis-related outcomes by tongue scraping, nonsurgical periodontal treatment (including oral hygiene instruction) and oral hygiene instruction/c...
