To determine the non-bonded interaction between methyl benzoate and boron nitridenanotube, we focused on an armchair single-wall boron nitride nanotube (9,9) With length 5 angstroms.The geometry of molecules was optimized using B3LYP method with 6-31g* basis set. Also reactivityand stability of methyl benzoate and boron nitride nanotube (9,9) was checked. Then NBO, FREQ,...

OBJECTIVE(S) Potassium benzoate (PB) is used as a substitute preservative for sodium benzoate primarily in dietetic foods where the sodium content is minimized. There are few reports about the teratogenic effects of PB. The purpose of this study is to investigate the teratogenic effects of PB on eye development in balb/c mice fetuses. MATERIALS AND METHODS Thirty female mice were divided to t...

Fruit spot disease of Phyllanthus emblica L. is one theproblems, which reduce the quality fruits at pre-harvest period. Fungal pathogen was isolated using tissue planting methods during November 2016 to December 2017. The fungus, Thielaviopsis paradoxa identified both morphological and molecular characterization based on internal transcribe spacer (ITS) region ribosomal DNA (rDNA). Mycelial gro...

In this study, an aerosol fluidized bed is used to coat particles. A new generator obtain coating solution droplets with a diameter of around 1 μm or smaller. Glass particles, which have mean 653 μm, were the non-porous core material and was sodium benzoate. Scanning electron microscope pictures analyzed by MATLAB image processing for evaluating coverage curvature effect. Monte Carlo simulation...

Article history: Received on: 15/03/2013 Revised on: 04/04/2013 Accepted on: 01/05/2013 Available online: A selective and reproducible high performance liquid chromatographic method has been developed for the determination of granisetron hydrochloride in presence of its hydrolytic, oxidation, photodecomposition and thermal degradation products. Successful separation of granisetron from its degr...

AIMS Mathematical models were created which predict the growth of spoilage bacteria in response to various preservation systems. METHODS AND RESULTS A Box-Behnken design included five variables: pH (2.8, 3.3, 3.8), titratable acidity (0.20%, 0.40%, 0.60%), sugar (8.0, 12.0, 16.0 * Brix), sodium benzoate concentration (100, 225, 350 ppm), and potassium sorbate concentration (100, 225, 350 ppm)...

Kinnow (Citrus nobilis × Citrus deliciosa L.) is a widely grown Citrus species known for its high quality fruit juice with good storage life. The present investigation is concerned with the enhancement of shelf-life of Kinnow fruit juice through refrigeration storage and addition of preservatives. Fruit juice was prepared from fruits harvested at complete physiological maturity and potassium me...

At present the view is commonly accepted that hippuric acid is produced chiefly by the kidney in most animals and exclusively by that organ in the dog. This conclusion is based largely on the well known work of Bunge and Schmiedeberg (1) who were able to dem0nstrat.e that hippuric acid was formed when blood containing benzoic acid and glycine was perfused through dog kidney. Furthermore, they f...

Abstract: The stability of aqueous and non-aqueous papaverine hydrochloride solutions exposed to the UV radiation is poor. In order to enhance its photo-stability suitable light absorbers may be used. There werefour photo-protectors considered in this work: 4-aminobenzoic acid, sodium benzoate, methyl 4-hydroxybenzoate and propyl 4-hydroxybenzoate, whose UV absorption spectra characteristics ma...
