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

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.

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.

of sun exposure‚ or vitamin D. An inverse relationship has been researched and found that those diagnosed with a deficiency in vitamin D can be at a higher risk for developing these forms of cancer. According to the American Cancer Society‚ 209‚060 cases of breast cancer‚ 21‚880 cases of ovarian cancer‚ 217‚730 cases of prostate cancer‚ and 102‚900 cases of colon cancer will be diagnosed in 2010 across the United States (1). Adequate intake or supplementation of vitamin D is a factor that can

INTRODUCTION In our experiment we tested the amount of vitamin C in a certain amount of lemon juice. We did this with the help of PCPIP which is an indicator that shows the presence if C vitamin. For this we used the mentioned indicator‚ pipette‚ three eprouvetes‚ 0.1% of C vitamin solution and lemon juice. First we had to get the volume of 0.1% vitamin C solution that is needed for our amount of PCPIP (2ml) to decolorize. Then we had to determine the volume of lemon juice that is needed to
