compressed biscuits (cbs) were developed using wheat flour, soy flour, sugar, oil and malt extract. combining of compression and dehydration technology were applied for production. packaging cbs using vacuum packaged, use of oxygen absorber (oa) and identical samples were aerobically packaged and stored at ambient and elevated (40°с) temperature for 12 weeks. the effect of different packaging a...

Headspace oxygen in sample vial for the purge-and-trap dynamic headspace/gas chromatography method oxidizes meat if held hours before purging, influences volatile profiles, and misrepresents the true composition of volatiles. Helium flush and helium flush plus oxygen absorber were used to eliminate residual oxygen and minimize oxidative changes in meat during sample holding time. Both helium fl...

Fresh gas flows of 1-5 l./min containing oxygen concentrations of 25-50% in nitrous oxide were led into a semiclosed circle absorber circuit. The resulting inspired oxygen concentrations were measured under conditions of spontaneous respiration. The lower the fresh gas flow, the greater was the discrepancy between fresh gas and inspired oxygen concentration. No association between minute volume...

Articles you may be interested in Structural and electronic modification of photovoltaic SnS by alloying Thin film photovoltaic cells are increasingly important for cost-effective solar energy harvesting. Layered SnS is a promising absorber material due to its high optical absorption in the visible and good doping characteristics. We use first-principles calculations based on density functional...

gaz is one of the traditional food products. ingredient of gaz has certain differences compared with other sweets & snacks, which in the preparation of them no oils, starch and flour is used. adverse color, taste and odor in gaz may has been created by oxidation in nuts at store condition. on the other hand, gaz becomes dry in inappropriate packaging at areas with low humidity and becomes soft ...

In the present study, the potential mutagenic effects of a packaging system for food containing oxygen absorbers was evaluated on a popular sweet bakery product (glazed doughnuts) stored at 20oC along its extended self life by using the Salmonella typhimurium Histest with the tester strains TA98, TA100, TA1535 and TA1537 and Escherichia coli Trptest with strains WP2uvrA and WP2uvrA pKM101. All ...

Photocatalytic oxidation of organic compounds proceeded efficiently in a hybrid system with ruthenium aqua complexes as catalysts, BiVO4 as a light absorber, [Co(NH3)5Cl](2+) as a sacrificial electron acceptor and water as an oxygen source. The photogenerated holes in the semiconductor are used to oxidize molecular catalysts into the high-valent Ru(IV)=O intermediates for 2e(-) oxidation.
