STUDY OF OXALATE ION CONTENT IN GUAVA FRUIT
INTRODUCTION
Guava is sweet, juicy and light or dark green coloured fruit. It is cultivated in all parts of India. When ripe it acquires yellow colour and has penetrating strong scent. The fruit is rich in vitamin C and minerals. It is a rich source of oxalate and its content in the fruit varies during different stages of ripening. Guava fruit, usually 4 to 12 cm long, are round or oval depending on the species. The outer skin may be rough, often with a bitter taste, or soft and sweet. Varying between species, the skin can be any thickness, is usually green before maturity, but becomes yellow, maroon, or green when ripe. Guava fruit generally have a pronounced and typical fragrance, similar to lemon rind but less sharp. Guava pulp may be sweet or sour, off-white ("white" guavas) to deep pink ("red" guavas), with the seeds in the central pulp of variable number and hardness, again depending on species

Oxalate is an organic acid, primarily found in plants, animals and humans. It is not an essential molecule and is excreted from our body in an unchanged form. Our body either produces oxalate on its own or it converts other molecules like vitamin C to oxalate. External...
