Citric Acid

Citric Acid is a weak organic acid. Citric Acid is a natural preservative and is also used to add an acidic or sour taste to foods and soft drinks. In biochemistry, Citric Acid is important as an intermediate in the citric acid cycle, and therefore occurs in the metabolism of virtually all living things. We are highly appreciated as an Exporter and Supplier of Citric Acid. The Citric Acid is used as an environmentally benign cleaning agent. Citric Acid exists in greater than trace amounts in a variety of fruits and vegetables, most notably citrus fruits. Lemons and limes have particularly high concentrations of the acid; it can constitute as much as 8% of the dry weight of these fruits (about 47 g/L in the juices). The concentrations of Citric Acid in citrus fruits range from 0.005 mol/L in oranges and grapefruits to 0.30 mol/L in lemons and limes. Within species, these values vary depending on the cultivar and the circumstances in which the fruit was grown. Our prices for Citric Acid are highly reasonable. Properties
