Vitamin C intake and plasma ascorbic acid concentration in adolescents
The relationship between vitamin C intake and status was investigated in a group of adolescents (13-14 years old). Dietary intakes were assessed using a 7 d weighed dietary record method, coupled with the collection of duplicate diets. Vitamin C intakes calculated using food composition tables were compared with values obtained by direct analysis of duplicate diets. Vitamin C status was judged ...
متن کاملDetermination of Vitamin C (Ascorbic Acid) in Orange Juices Product
This research describes a voltammetric approach to determine amounts of vitamin C (Ascorbic acid) in orange juice sample, using three screen printed electrode. The anodic currents of vitamin C were proportional to vitamin C concentration in the range of 0 – 10.0 mM with the limit of detection of 1.36 mM. The method was successfully employed with 2 μL of the working solution dropped on the elect...

متن کاملEncapsulation of Vitamin C (ascorbic Acid and Amla Pulp) to Develop Vitamin C Fortified Ice Cream
In this research study, two percentage of alginate as wall material and 0.1m cacl2 as hardening bath were optimized for encapsulation (bead formation) through extrusion process. The encapsulation efficiency (ee) at 500mg of ascorbic acid was highest (74%) compared to 750 mg and 1000mg. Ee was highest (95%) at 40g for amla pulp. Encapsulated ascorbic acid beads had significantly higher the conte...
