Citrus fruits 28 Apr 2011 We have developed an automated high‐throughput assay for the determination of vitamin A (retinol), ergocalciferol. (25‐OH D2) Total vitamin C (ascorbic acid + dehydroascorbic acid) has been investigated using two methods, the first. UV-spectrophotometric method and the second titration Determination of vitamin C in some fruits and vegetables in. Davanagere city, ( Karanataka) - India. G. Vasanth Kumar*, Ajay Kumar K., Raghu Patel G.R. and S. Other optical methods for vitamin C estimation include spectrophotometrical determination of iodine reacted with ascorbic acid [52] and chemiluminescence [ 53]. A
This is the endpoint of the titration. The method is suitable for use with vitamin C tablets, fresh or packaged fruit juices and solid fruits and vegetables.
