Oxalic acid

From Cookipedia


Sorrel, an interesting, yet fairly uncommon vegetable / herb that is high in oxalic acid.

Oxalic acid is an organic compound with the formula H2C2O4. It is a colourless crystalline solid that dissolves in water to give colourless solutions.

Occurrence in foods and plants

Calcium oxalate is the most common component of kidney stones. Early investigators isolated oxalic acid from wood-sorrel (Oxalis). Its presence makes it dangerous to eat unripe carambola or monstera fruits. Members of the spinach family are high in oxalates, as is sorrel. Rhubarb leaves contain about 0.5% oxalic acid and jack-in-the-pulpit (Arisaema triphyllum) contains calcium oxalate crystals. ===Industrial uses=This table was originally published in Agriculture Handbook No. 8-11, Vegetables and Vegetable Products, 1984.
