Tricalcium citrate

The citric acid obtained from fermentation is removed from the culture by precipitation. The precipitation is formed by the addition of Ca(OH)2 200 gl , at 70 °C. The pH of solution is adjusted to 7.2. Tri-calcium citrate tetrahydrate is collected by filtration. The tricalcium citrate as filter cake is dissolved in H2S04 at 60 °C with 0.1% excess, the solid retained is CaS04 and the free citric acid is obtained. The free concentration of citric acid is determined with an enzymatic kit available from Merck. GC/HPLC is recommended for high accuracy of any research work.5... [Pg.285]

Citric acid occurs widely distributed in nature in many fruits. It is present in raspberries, gooseberries, currants, and other acidulous fruits. It is usually obtained from unripe lemons, the juice of which contains about six per cent of the free acid. In isolating the acid, the juice is neutralized at the ordinary tem-perture with calcium carbonate, and filtered. Tricalcium citrate dissolves readily in cold water, but is difficultly soluble in hot water. As a consequence, when the solution of the citrate obtained from the lemon juice is boiled, the calcium salt of the acid precipitates. This is separated and treated with an equivalent quantity of sulphuric acid after the removal of calcium sulphate, citric acid is obtained by evaporation of the solution to crystallization. Citric acid is formed as the result of the fermentation of glucose by citromycetes pfefferianus. It is prepared on the technical scale in this way. [Pg.299]
