Transcript of Does Exposure to light effect the amount of Vitamin C in jui

Results:
Does Exposure to sunlight affect the amount of
Vitamin C in juice?

OUR HYPOTHESIS:
Experiment Two
How we tested our
hypothesis...
-Two experiment
A.
How the sun affects vitamin C from the source
B.
How sun affects vitamin C in juice form
Chemistry 102-02
by: Edelweiss Vaovasa
and Diana Betancourt

EXPERIMENT ONE:
Results:
About Vitamin C:
-Also known as: Ascorbic Acid, L-ascorbic acid, and L-ascorbate
-Many health benefits
-Chemical formula: C6H8O6
-Comes from many citric fruits and vegetables
About the Sun:
-One of many sources of Vitamin D
-The skin synthesize vitamin D from exposure to sunlight and other artificial sources of Ultraviolet B (UVB) light.
Sunlight does affect the
amount of Vitamin C
in juices, increasing the amount in Juice.
pineapple orange
tree
Hamlin Orange tree
Valencia orange
Tree
Tested before ripening, at ripening, and before ripening
Sunlight affect on Vitamin C from the source
Sun System PAR Meter
An integrated sensor to measure photosynthetic active radiation
where we tested
Vitamin C Strips:
Used gives us the range of Vitamin
C.
Step 1:
Step 2:
Step 3:
Titration Experiment
Using iodine and starch solution in order to find the amount of Vitamin C
Valencia Oranges had the most Vitamin C
- had the most sun during June
- grew during Winter even without the least amount of sun
How sun affects vitamin C in juice form
3 cups of each (9 cups total):
-one set outside in the sun
-one set inside, regular
amount of sun
*
- one set outside, covered
- one set inside, covered
* our control group
lowerst
highest
-closed cups on the inside and outside lost Vitamin C, but cups on the outside lost the most.
-open cups outside lost a significantly larger amount of Vitamin C than the ones open inside.
Conclusion
Sunlight
increases
Vitamin C during growth of citrus fruit or vegetables, but
diminishes
Vitamin C over time in juice form.
