1. The document discusses measuring and comparing the vitamin C content in different types of orange juice and other food samples. 2. Factors like growing conditions, processing methods, storage, and exposure to heat/light can affect a food's vitamin C concentration. 3. A procedure is described where indicator solution is added drop by drop to orange juice samples until the color changes, allowing calculation of relative vitamin C amounts.

1. Vitamin C Content Group 3

2. Do different types of orange juice contain the same amount of vitamin C?

3. If the factors of determining the vitamin c (the plant's growing conditions, method of processing, storage conditions, and exposure to heat, light or metals) are different, the vitamin C content will differ.

4. Objectives: 1. To measure and compare the Vitamin C content in a variety of food samples. 2. To determine the effect of various factors on Vitamin C concentration.

5. Vitamin C is best known to be found in citrus fruits. It maintains collagen, helps in healing of wounds and repair of tissues, helps in forming red blood cells. It should be in our bodies as much as possible. Since vitamin C should be ingested as much as possible, we would need to be able to get the most vitamin C in one day. :)
