A new method to determine epoxide concentrations in oxidized oils was developed and validated using (1)H NMR. Epoxides derived from lipid oxidation gave signals between 2.90 and 3.24 ppm, well separated from the signals of other lipid oxidation products. To calibrate, soybean oils with a range of epoxide concentrations were synthesized and analyzed using (1)H NMR by taking the sn-1,3 glycerol p...

the effect of ascorbic acid (aa) and butylated hydroxyanisole (bha) supplementation on aflatoxicosis in broiler chickens (1 to 42 days of age) was investigated (250, 500, 1000 and 2000 ppm for aa and bha) in diet containing 1 ppm total aflatoxin (af: 76.45% afb1, 10.52% afb2, 9.89% afg1 and 3.14% afg2). a total of 300 day-old broiler chicks were divided into ten treatment groups (t1=control; t2...

—Formalin is currently the only aquaculture drug approved by the U.S. Food and Drug Administration for the control of fungi on the eggs of all finfish. The efficacy of formalin for disinfecting hybrid catfish (channel catfish Ictalurus punctatus 3 blue catfish I. furcatus) eggs was examined and compared with that of three other potential chemotherapeutants. Two experiments were conducted to eva...

Ficus benjaminais a very popular and resistant indoor plant in temperate areas. Cutting is the easiest propagation method of this plant and it requires special treatments such as auxin and appropriate rooting medium. In order to test the suitable auxin (IBA) concentration and rooting media, a factorial experiment carried out based on randomized complete block design with three replications. Exp...

In this study we developed a low cost sensor for measuring the concentration of hydrogen peroxide (H₂O₂) in liquids utilizing a spectrometric method. The sensor was tested using various concentrations of a peroxidase enzyme immobilized on a glass substrate. H₂O₂ can be catalyzed by peroxidase and converted into water and oxygen. The reagent 4-amino-phenazone takes up oxygen together with phenol...

Farmers have been growing marigold commercially but they are still lacking knowledge on procedure of postharvest handling flowers. This has created a huge problem for those farmers since cannot store their own produce longer period time thus facing problems in marketing. In order to inform the with best means preservation cut flowers so that could fetch good market price product. A lab experime...

In concentration of hydrogen peroxide, first, the solution should be quite pure, and then, it concentrate with methods such as vacuum distillation and cooling crystallization, because impurities in the hydrogen peroxide solution in high concentrations are causing decomposition of this substance; that is very dangerous. The purpose of this article is separation of chromium and magne...
