Citric acid production.
Citric acid is a commodity chemical produced and consumed throughout The World. It is used mainly in the food and beverage industry, primarily as an acidulant. Although it is one of the oldest industrial fermentations, its World production is still in rapid increasing. Global production of citric acid in 2007 was over 1.6 million tones. Biochemistry of citric acid fermentation, various microbia...
متن کاملCitric Acid Determination
Three types of methods have been proposed for the determination of citric acid in urine. Salant and Wise (1) used the unspecific mercuric sulfate reagent of Deniges (2) in a study of the toxicity of citrates. Thunberg (3) developed an enzymatic method employing a dehydrogenase said to be specific for citrate. The remaining methods depend on the so called pentabromoacetone method of Stahre (4), ...
متن کاملphysicochemical properties of crude and purified locust bean gums extracted from iranian carob seeds
in this research, seeds of iranian carob trees grown wild in kazeroon city (fars province) were used to extract iranian locust bean gum as a seed galactomannan. chemical composition, solubility, and rheological properties of crude and purified gums were investigated and compared with a commercial (sigma) locust bean gum (lbg) sample. chemical composition of the purified iranian lbg was similar ...
متن کاملCitric Acid and Bone Metabolism
From the sedimentation and diffusion constant values obtained in a solution containing 1 g./ 100 ml. H substance, and using the determined value of the partial specific volume, the molecular weight was calculated from the usual equation (Svedberg & Pedersen, 1940) giving a value of 320 000. From the same data the frictional ratio f/fo obtained was 4-2. This corresponds to an axial ratio of > 10...
متن کاملCitric acid and calcium metabolism.
Recently there has been increasing realisation of tile important part played by citric acid in the body’s metabolism. Thus administration of pyruvic acid, the intermediate metabolite common to the utilisation of carbohydrate, protein and perhaps fat, causes increased urinary excretion of citrate. Many tissues can form citrate by condensation of pyruvate and oxalacetate followed by reduction, an...
