• The COD of spent H 2 S scavengers was reduced up to 98% by hydrothermal oxidation. Increase temperature from 200 350 °C enhances the reaction rate seventyfold. Triazine, monoethanolamine and dithiazine were converted in less than 1–3 min. Organic nitrogen sulfur are mainly into ammonium sulfate. Short chain carboxylic acids, pyrazines pyridines intermediate products. feasibility oxidation a w...

The evaluation of volatiles in food is an important aspect production. It gives knowledge about the quality foods and their relationship to consumers’ choices. Alcohols, aldehydes, acids, esters, terpenes, pyrazines, furans are main chemical groups that involved aroma formation. They products processing: thermal treatment, fermentation, storage, etc. Food a mixture varied molecules. Because thi...

How external factors affect virgin rapeseed oil (VRO) flavor was explored from the perspective of key flavor-related compounds (KFCs). Light (sunlight, ultraviolet light, and dark), temperature (ambient 60 °C), packaging materials (glass plastics) were selected. Induction periods (IPs) samples in surface hydrophilicity measured. The results showed that aldehydes increased 3.654 to 10.183 82.762...

Trapping is considered a powerful tool in the monitoring and control of fruit flies high economic importance such as Mediterranean fly, Ceratitis capitata (Diptera: Tephritidae). However, cost trapping and, some cases, safety chemicals used baits are concerning for growers environment. Here we present novel, low cost, environmentally friendly, female-specific bait C. capitata, called Biodelear,...

Field muskmelon seeds contain plenty of oil. However, its potential as vegetable food oil has not been explored comprehensively. This study used three different processes, cold extrusion (CE), coasting followed by (R-CE), and supercritical fluid extraction (SFE), for the field seed (FMSO) studied quality characteristics such color, fatty acid composition, volatile components. The found that FMS...

The reaction of benzil, 1-alkyl-2-arylethanediamine dihydrochloride and sodium acetate trihydrate gave the target molecule dihydropyrazine derivatives 30-34. The compounds have been characterized on the basis of their FT-IR, 1H NMR and 13C NMR spectroscopies. All the compounds are screened for their antibacterial activity against Staphylococcus aureus, Klebsiella pneumoniae, Pseudomonas aerugin...
