driving question‚ or topic‚ was “Does the level of vitamin C change over time in Orange Juice.” After I viewed the website‚ I got very excited because it had simple step-by-step instructions about how to test the level of vitamin C. On the following page are the directions. I think I am really excited to do this project because it sounds very interesting and fun to do. I hope to prove what the driving question/topic entails. Paragraph 2 – Background (5 Facts) • Vitamin C helps to repair and regenerate

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

Title : The Vitamin C content of fruit juice Aim : To investigate the vitamin C content of fruit juice. Introduction : [2]Vitamin C‚ also known as the ascorbic acid or the L-ascorbate‚ is required for the growth and repair of tissues in all parts of our body. It is necessary to form collagen‚ an important protein used to make skin‚ scar tissue‚ tendons‚ ligaments‚ and blood vessels. Vitamin C is essential for the healing of wounds as well as for the repair and maintenance of cartilage‚ bones

Activity 1.21- Is high Vitamin C all it claims to be? Purpose: * To investigate the vitamin C content of fruit juice * To investigate which type of fruit juice provides the most vitamin C The quantity of vitamin C in food and drink can be determined using a simple colour test. Vitamin C decolourises the blue dye DCPIP (dichlorophenolindolphenol). Vitamin C is an antioxidant and reduces the DCPIP. DCPIP changes from blue to colourless (or slightly pink) as it becomes reduced. We will

: The Vitamin C Content of Fruit Juices Lecturer : Madam Rita Rohaizah binti Sohari TITLE: THE VITAMIN C CONTENT OF FRUIT JUICES INTRODUCTION Vitamin C which is also known as ascorbic acid is an essential nutrient for human. It is a water-soluble vitamin that is necessary for normal growth and development. Water-soluble vitamins dissolve in water. Leftover amounts of the vitamin leave the body through the urine. That means a continuous supply of vitamin is needed in daily

Vitamin C Content of Apple Juice Introduction Complete lack of ascorbic acid (a.k.a Vitamin C) in the diets of humans and other primates leads to a classic nutritional disease‚ scurvy. This disease was widespread in Europe during the fifteenth and sixteenth centuries‚ but it is rare today. Ascorbic acid is widely distributed in nature‚ but it occurs in extremely high concentrations in citrus and green plants such as green peppers and spinach. Ascorbic acid can be synthesized
