abstractbackground and objective: microwave-assisted extraction (mae) is one of the novel, fast, and efficient methods for extraction of bioactive compounds. the aim of this study was optimization of mae of betalains from red beet (beta vulgaris) and evaluating antioxidant activity of its methanolic extract.materials and methods: the effects of independent variables namely, microwave power leve...

the effect of pre-treatments in combination with hot air, vacuum and hot-a microwave drying methods the progress of the drying process, and textural, and colour and rehydration rate on button mushroom (agaricus bisporus) slices were investigated. in this work, one of the following methods: hot air, vacuum drying or microwave-assisted convective drying and also different pre-drying treatments, v...

background: there are many varieties of compounds in chemical and petrochemical wastewater. one of the important members of the chlorophenols (cps) family is ρ-chlorophenol. this pollutant is introduced into the environment through various human activities such as waste incineration, uncontrolled use of wood preservatives, pesticides, fungicides and herbicides, as well as via bleaching the pulp...

Reusable silica supported perchloric acid and potassium bisulphate have been prepared and explored as green catalysts for thiocyanation of aromatic compounds under conventional and solvent free microwave assisted conditions. The microwave assisted protocol exhibited remarkable rate accelerations and offered selective thiocyanation of aromatic and hetero aromatic compounds in good yields. Reacti...

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...

The broad bandwidth and low loss offered by modern photonics have led to an ever-increasing interest in the design and implementation of photonically assisted solutions for the generation, processing, control and distribution of microwave signals, an area called microwave photonics. In this article, a tutorial on microwave photonics is presented with an emphasis on optical generation of microwa...

salmonella     species show different disease syndromes and host specificity, according to their antigenic profile. salmonella enterica serovar typhimurium is one of the most frequently isolated serovar from foodborne outbreaks. poultry meat has been identified as one of the principal foodborne sources of salmonella. in this study, the effect of microwave treatment of chicken meat samples wh...
