Effect of temperature on Vitamin C content

Besides my experiment there have been other experiments that have tested temperature’s effect on ph. They also wanted to know whether temperature affects the ph. I found an experiment online called “Effect of Temperature on the pH of orange juice” done by students from Nease High School. Unlike my project, they only tested Orange Juice. They used 5 different temperatures, and the result was that the temperature had no effect. Another experiment I found online called “ Does storage temperature affect the ph of Orange Juice” by Anna Elizondo also only used Orange Juice. Her results were that the juice was more acidic at a hot temperature. The last experiment i found was on the lines of my experiment, but was more about my hypothesis. It was called “Does Storage Temperature Affect Orange Juice 's Acidity?”. Like the other experiments, this one only used Orange Juice. They used ph paper to measure the acidity at 40 degrees-50 degrees over the span of 2 days. Their conclusion was that the ph was still the same.

15. Which of the following is NOT a possible toxicity symptom associated with vitamin C excesses?

In determining the melting point range of the aspirin, a capillary tube (sealed at one end) was one-third-filled with the dried aspirin. The capillary tube and a thermometer were immersed in an oil bath. The temperature at which the solid started to melt and the temperature when the entire sample was completely liquefied were recorded as the melting point temperature range.

Vitamin A and D have showed unexpected and crucial effects on immune system. Vitamin A includes innate immune towards microbial infection, absence of vitamin A can increase the chance of bacterial, viral, and parasitic infection. Also excessive intake of vitamin A Is associated with toxicity, including blocked hematopoiesis, mitogen-induced T-cell spread, antigen-specific antibody production, and an increased susceptibility to infectious organisms. Vitamin A is also given by Retinoid supplement to treat the skin effects of T-cell lymphoma. Vitamin C also known as Ascorbic Acid also contribute in innate immunity system, Vitamin C works during infection to prevent oxidative damage. Lower concentration of vitamin C in leukocyte is related to reduce immune response in humans. It has been proven that Vitamin C concentrations in the plasma and leukocytes rapidly decline during infections and stress. Iron chelators such as desferrioxamine inhibit the activity of phagocyte oxidase and reduce reactive oxygen intermediate-dependent killing of bacterial pathogens, both in vitro and in vivo. Lastly, Zinc is a dietary trace mineral that is responsible for growth and development, and it is essential for the function of cells of the immune system. It increased susceptibility to

Vitamin C is needed for a baby to develop well as it helps our bodies fight off infection and disease as well as helping to heal wounds. It can also prevent anemia. Some lactating mothers may need more vitamin C than others, especially if overcoming a cold, surgery or some form of injury. The dose needed is 115 mg or 120 mg per day. Food sources in which vitamin C can be found are citrus fruits, broccoli, Kiwi, cauliflower and bell peppers.

They experienced success with this remedy due to the large amounts of vitamin C present in the

The greater the amount of vitamin C there is in the juice, the less juice it will take to decolourise it

B3 (niacin) is common in fortified breakfast cereals, beef liver and chicken breast. B5 (pantothentic acid) can be found in breakfast cereals and beef liver. B6 (pyridoxine) is found in foods such as chickpeas and yellow fin tuna. B7 (biotin) can be found in long grain white rice and cereals and vitamin B12 is common in meats, clams and liver. Vitamin C is found in many of the fruits we consume such as juice, citrus, peaches and vegetables like bell peppers (Tumbarello, 2012). Collectively many water soluble vitamins can also be found in a wide variety of foods such as fresh vegetables, legumes, citrus fruit, bananas, avocados, walnuts, potatoes, eggs, pork, roast beef, chicken and fish like tuna, salmon and trout. They are also found in fortified cereal grains, breads, oatmeal, and wheat bran.

1) Pour 25 mL of the 1 M hydrochloric acid into the beaker and rinse the solid by swirling the acid around in the bottom of the beaker.

another minute. After the minute, I cleaned the Gram’s iodine with purified water then added three drops

Vitamin C also known as ascorbic acid is needed for growth and maintenance of healthy tissues, especially skin, blood vessels, bones, gums, teeth. Vitamin C aids in resistance against infection and healing of wounds. It also helps the body absorb iron from food. Vitamin C can be found in green vegetables, potatoes, tomatoes and citrus fruits such as oranges and lemon. A lack of vitamin C can cause scurvy, iron deficiency and poor wound healing. A healthy diet

Vitamin C is an organic compound that is also known as ascorbic acid. The molecular formula for Vitamin C is C6O8H6. This structure contains a 5-membered ring. Vitamin C contains 4 alcohol functional groups, an alkene, and an ester. Within the ring it contains one double bond, the carbon=carbon bond in the ring structure, this is an alkene functional group. The Vitamin C structure also contains an ester which helps form the five-membered ring.

Vitamin C should be taken in through diets, fruits and vegetables so that it can have its best effects and is good for our health. Vitamin C supplements are only used as addition if our bodies do not have enough Vitamin C.

We live in a society in which we are in a state of constant fear of diseases. From when we are young we are taught repeatedly to wash our hands before every meal and to eat an apple daily. Moreover, we are catechized on a regular basis to bundle up so we do not catch a cold or pneumonia. Likewise, our doctors advise us to visit them annually to make sure we don’t have deficiency related disorders such as scurvy or anemia. What if there is a vitamin that could aid in preventing the aforementioned illnesses? Would it not be worth a try? Consider this an introduction to vitamin C! Details on this “wonder vitamin” are elaborated in the subsequent paragraphs!

Hypothesis & Rationale: Pasteurization decreases the natural level of vitamin C in orange juice because the heat may cause the chemical bonds in ascorbic acid to break down and disband.
