This study presents Saccharomyces cerevisiae, an alcohol fermentation waste, for removal of acidic dyes (Red 3:1 & Orange 13) even after chemical and physical modification. Biosorption performance was found 96.29% through untreated biomass and 97.31% through pretreated biomass with hydrogen peroxide solution for Red 3:1, whereas 93.49% through untreated biomass and 94.71% through pretreated bio...

The problem of estimating quantitatively the components of a mixture of naturally occurring estrogens has been attacked through the preparation of their p-phenylazobenzoyl (azoyl) esters and separating these esters by the chromatographic adsorption technique (1). By this method, the monoazoates were quantitatively separated from the diazoates. Hydrolysis of these esters and suitable extraction ...

In a previous paper (1), the authors have shown that the fumigation of citrus trees with hydrocyanic acid (HCN) for pest control, at a time of the year when the fruit buds are in a certain stage of development, produced ridges and sectors in the outer portion of the peel (flavedo) of the fruit. In the navel orange, Valencia orange and grapefruit varieties, fumigation of trees in February produc...

Spectrophotometric measurements of the Fricke–gelatin–xylenol orange (FGX) gel dosimeter demonstrated reproducible linear dose response up to 25Gy. However, oxidation processes continue post-irradiation, affecting the response of this dosimetry system. Additional oxygenation during preparation increases the sensitivity of the gel but does not improve the auto-oxidation stability of the dosimete...

Citrus is one of the most important fruit crops in world. junos Siebold ex Tanaka cv. Pujiang Xiangcheng a new rootstock with good grafting affinity and multiple abiotic stress tolerance. In this study, effects ‘Pujiang Xiangcheng’ two commonly used rootstocks for maxima (Burm.) Merrill Guanxi Miyou, considering their growth, photosynthetic performance, phytohormones quality, were evaluated. Th...

ABSTRACT: The present research presents an analytical methodology based on High Performance Liquid Chromatography (HPLC) and Principal Component Analyses (PCA) for simultaneous quantification differentiation of organic acids sugars in commercial fruit juice samples (orange, grape, apple tangerine). In addition to the development method that generated suitable validation paramters quantitative a...

a simple, economical, precise and fast visible spectrophotometric method has been developed for the determination of azathioprine in tablet dosage form. developed method is based on the formation of extractable colored complex of drug with colouring agent indigo carmine and methyl orange. a wavelength maximum was found to be 683.7 nm and 566 nm. the concentration range of 15-50 μg ml-1 with of ...

Orange juice concentrates were packaged aseptically by a “Dole” aseptic canning machine using 6 oz metal cans. The final juice products (ll”, 34’, 44’, 58” Brix) were stored between -18” and 36°C and tested periodically for nonenzymatic browning, ascorbic acid destruction, furfural and sensory changes. Nonenzymatic browning, the main deterioration phenomena in these products, was satisfactorily...

ABSTRACTThis study aims to obtain the appropriate and accepted concentration of papaya orange kalamansi mixture in manufacture jelly drink with observation parameters organoleptic test (color, aroma, taste, texture), chemical analysis (pH level total acid analysis), sensory (syneresis test). The used a Complete RandomIzed Design (RAL). factor studied was addition oranges concentration. will use...
