V. Kabasakalis et al., STUDY OF OXALIC-ACID CONTENT IN VEGETABLES AND ITS IMPLICATION ON HEALTH, Fresenius environmental bulletin, 4(7), 1995, pp. 445-448
In this work we determined the oxalic acid content in several vegetabl
es of Thessaloniki's area, using two methods 1,2. The results of the t
wo methods have been found to be sufficiently closed. The oxalic acid
content was found to vary from 0.195 % in peas to 7.336 % in spinach i
n dried samples whereas in tomatoes it was found to be relative to the
ir maturity degree.
