Oxalic Acids in Vegetables Determination of Free and
نویسنده
چکیده
Vegetables generally contain more or less oxalic acid, which is produced by metabolism in cytoplasm.12 Most of the oxalic acid is fixed as calcium oxalate to protect protoplasm from its toxic action.3 Vegetables containing a considerable quantity of oxalic acid are usually boiled before being cooked to remove any harshness.4 The oxalic acid contained in food is determined by the KMnO4 titration of calcium oxalate, gas, liquid or

Determination of Carboxylic Acids in Apple Juice by RP HPLC
Low molecular weight organic acids are most predominant in apple juice among these components fumaric acid was not exceed more than 5 ppm. It was thought that the HPLC is the best method of the determination of organic acids in the apple juice. In this study, chromatographic separation of organic acids of apple juice was obtained by preparing a sample and by applying them to acid phase for ...

The rate of metal transfer from the solid phase to solution is an important factor governing their concentration in the soil solution and its availability. In this research, the release rate of Zn in contaminated soils from Isfahan was studied using solutions citric acid, oxalic acid and malic acid 0/01 M during the period of 2 - 504 hours and its relationship with soil characteristics was inve...
متن کاملRole of Hydrogen Transfer and Ionic Bonding on RR, SS and RS Medetomidine Conglomerates/Acids Stability: A Theoretical Study
This study focuses on RR, SS and RS medetomidine (MM) and inclusion of several achiral acids to distinguish which acid can help conglomerate formation instead of crystallizating racemic mixtures by defining the low-lying energy of their structures. Favorable orientation of acids was determined in interaction with the MM enantiomers after optimization. The most noticeable interactions include hy...
متن کاملDetermination of residues in honey after treatments with formic and oxalic acid under field conditions
Formic acid and oxalic acid field trials for control of Varroa destructor were carried out in autumn according to the Swiss prescriptions during three successive years in different apiaries in Switzerland. The following parameters were determined in honey that was harvested the year after treatment: formic acid, oxalic acid and free acidity. The following range of values were found in honeys of...

The study of drying and wetting cycles in soils is important due to their effects on plant nutrition and soil fertility as well as environmental issues. Therefore, a laboratory experiment was set up with a completely randomized design and factorial arrangement in three replications to identify the influence of wetting and drying cycles in combination with or without application of organic acids...
