Determination of Ascorbic Acid Contents of Fruits and Vegetables
Ascorbic acid contents of some fruits and vegetables in Abakaliki were analyzed through titrimetric methods. The results recorded the concentrations (mg/100g) of ascorbic acids in various fruits as orange (15.47 ± 0.23), lemon (12.87 ± 0.45), grape (2.00 ± 0.10), paw-paw (46.40 ± 1.65), apple (2.20 ± 0.10), banana (1.87 ± 0.06), carrot (1.80 ± 0.04), pineapple (2.80 ± 0.10), water melon (2.27 ±...
متن کاملDetermination of L- Ascorbic Acid in Plasma by Voltammetric Method
Voltammetric techniques have been considered as important methods among the analytical techniques used for the identification and determination of trace concentrations of many biological molecules such as L-ascorbic acid (AA). L-ascorbic acid is an electro-active molecule, though it is difficult to determine its value directly with a majority of electrodes made of carbon and transition metals, ...

متن کاملRapid Determination of Ascorbic Acid in Fresh Vegetables and Fruits with Electrochemically Treated Screen-Printed Carbon Electrodes
This study demonstrates a new electrochemical method for rapid determination of ascorbic acid in real samples with electrochemically pretreated screen-printed carbon electrodes. Cyclic voltammetry results indicated that the electrochemically activated electrodes possessed an excellent electrocatalytic activity toward ascorbic acid oxidation and can be successfully used for its selective and sen...
متن کاملDetermination of Ascorbic Acid in Vegetables by Derivative Spectrophotometry
Determination of ascorbic acid (AA) in garlic, green pepper and chestnut was performed by derivative spectrophotometry without using any pre-separation or background correction techniques. The method is based on the measurement of the distances between two extremum values (peak-to-peak amplitudes) in second and third order derivative spectra of the extracts. Ten percent trichloroacetic acid was...
