how to find oxalate content in guava
Oxalate content in Guava fruit generally increases as the fruit ripens. This is due to the breakdown of pectin and other cell wall components, releasing oxalate stored within the cells. As the guava ripens, the activity of enzymes involved in oxalate metabolism changes, leading to an accumulation of oxalate in the fruit. However, the exact levels can vary depending on the variety of guava and environmental factors.
It increases as it ripens. :D Now, that is what I wrote in my practical notebook. B-)
Take 10 gms of fresh guava & crus it into a fine pulp using pestle-mortar. Transfer the pulp to a beaker and add 50ml of dil.H2SO4. Boil the contents for about 10 mins. Cool and filter the contents into a 100ml measuring cylinder. Make up the volume upto 100ml by adding distilled water. Tae 20ml of the solution in a titration flask and add 20ml of dil.H2SO4 to it. Heat te mixture to about 60C and titrate it against N/20 KMNO4 solution taken in the burette. End point: Appearance of pale pink color..... This should be done with different guavas at their different stages of ripening.
Some fruits that contain oxalate ions include blackberries, raspberries, strawberries, and kiwi fruit. These fruits may contribute to the formation of kidney stones in individuals who are susceptible.
Oxalic acid can be extracted from guava fruit by first crushing the fruit to release the juice, then filtering the juice to remove solid particles. The juice can then be heated and treated with a calcium source such as calcium hydroxide to form calcium oxalate precipitate, which can be separated to obtain oxalic acid. The oxalic acid can then be further purified through crystallization or other methods.

They always have oxalate in guava food. it's just a natural substance within it.
