Analysis of oxalate of fresh and stored tomato juice Essay Example

justify">The presence of oxalate ions and oxalic acid content in tomatoes is also a cause of kidney stones. Several researches have proven that the absorption of dietary oxalate is a major contribution on urinary stones. To avoid the risk of formation of kidney stones, it is, therefore, recommended that people should limit the intake of oxalate ions and calcium to bind whatever oxalate is ingested. A daily intake of 800-1200 mg of calcium per day for an adult is recommended by physicians to prevent stone formation. Accurate information on the oxalate contents of food is much harder to come due to difficulties in measuring it.

The oxalate ions present in tomato fruit juice is measured by titration methods. The study helped to analyze of tomato fruit juice on health. The study showed contribution of tomato fruit juice in the formation of stone. This study also showed that the consumption of fresh tomatoes is much beneficial than the consumption of stored tomatoes. The estimation of oxalate level in the fruit juice will be done by titration against standard potassium permanganate and standard sodium hydroxide solution.

Difference in the volume of potassium permanganate and sodium hydroxide consumed will correspond to the total oxalate. Keywords: Tomato, oxalic acid, oxalate ion, titration, sodium hydroxide, potassium per magnate. Introduction :Tomato is one of the world's most popular and widely cultivated fruit vegetable.
