Measuring the Vitamin C content in a variety of fruit juices Background Information Vitamin C‚ also called ascorbic acid‚ is a water soluble vitamin. It is a powerful reducing agent that is able to decolourise blue DCPIP (2.6-dichlorophenol indophenols). The decolourisation of DCPIP can therefore be used to calculate the vitamin C content of a variety of fruit juices. Research Question – To determine how the content of Vitamin C (%) will differ in fresh fruits (orange‚ mango‚ lemon‚ lime‚ blackcurrant

And to make sure you don’t get too much of these vitamins you should make sure you are eating the right foods to maintain a healthy diet. The other vitamin classification

THE VITAMIN C CONTENT OF FRUIT JUICE Aim: To investigate the vitamin C content of fruit juice.Hypothesis: I believe the more drops of fruit juice taken to decolourise DCPIP‚ the smaller the amount of vitamin C in that fruit juice. This is because DCPIP needed to be decolourised by ascorbic acid in fruit juice‚ so less concentration of ascorbic acids means that more ascorbic acids is needed to decolourised DCPIP. I believe that freshly squeezed orange is going to have the most Vitamin C content

Temperature on Content of Vitamin C Introduction A daily intake of Vitamin C is essential for humans. Without it‚ the disease scurvy develops as sailors‚ explorers and people during the long winters in the Northern hemisphere found before the time of Captain Cook. The British Navy started giving sailors lime juice to prevent scurvy on long voyages in 1795. Vitamin C is found in high levels in foods such as oranges‚ limes‚ lemons‚ blackcurrants‚ parsley and capsicums. Vitamin C is water soluble and

Aim(s) of the experiment (objectives) To determine the concentration of vitamin C in different kinds of juices. Hypothesis Freshly squeezed juice will have the most vitamin C compared to the other types of juices and drinks‚ because the fruit is picked fresh‚ and it is not stored‚ preserved or exposed to oxygen.

Determination of the concentration of vitamin C in fruits/vegetables by using the DCPIP test (2008) Principle : Vitamin C is a strong reducing agent. It can decolorize the blue dye DCPIP. The amount of vitamin C in a food sample can be estimated by the amount of it that is used to decolorize a fixed amount of DCPIP. Apparatus : Test tube‚ clean and dry Test tube rack 5 ml syringe or a good quality squeezing pipette 1 ml pipette

RICKETS For Scientific Principles and Health and Disease By: Mackenzie Gray 112-69-7540 April 7‚ 2010 Rickets is a disease that deals with a deficiency with Vitamin D. Vitamin D is important by controlling calcium and phosphate levels. If the blood levels of these minerals become too low‚ the body may produce hormones that cause calcium and phosphate to be released from the bones eventually this leads to weak and soft bones.
