Introduction:
Citrus fruits and derived products have a beneficial effect on the human health because of its
nutritional and antioxidant properties and their consumption is associated with a decrease in the
incidence of cardiovascular disease and reduction of the risk of certain cancers and also. During
the processing of citrus fruit for juice, peels are the primary by products and phytochemicals are
abundant in citrus peels. As you would expect, pesticide, herbicide and fungicide residues
are highest on the peel of oranges These compounds have been associated with healthy properties
ascribed
to
their
antioxidant
activity
and
free
radical
scavenging
abilities.
Phenolic compounds and antioxidant activities in citrus peel have been widely investigated and
they have been found to possess antiallergenic, antiartherogenic, anti-inflammatory, antimicrobial,
antioxidant, antithrombotic, cardioprotective and vasodilatory effects.
All species help move chi stagnation. Although all species share certain properties, there are
some differences; Mandarin Orange Peel is an anti-inflammatory, cholagogue, carminative,
diuretic and tonic, and the green or unripe orange peel is a cholagogue and carminative. The bitter
Orange Peel moves chi stagnation and is a carminative, stimulant, stomachic, expectorant and
tonic. Additionally, different species/parts have different uses. Mandarin Orange Peel – catarrh,
chest congestion, gas, indigestion; Green or Unripe Citrus Peel — abscess, bloating, breast cancer,
gall bladder congestion, liver stagnation; Bitter Orange Peel – flatulence, indigestion, stagnation in
the digestive tract, tumors. Using the peels as a digestive aid stimulates the production of
hydrochloric acid. The high content of bioflavonoid helps to strengthen the capillaries and tissues
in the body. Orange flower water is used as a sedative.
Meanwhile, mosquitoes are a family of small midge-like flies, the Culicidae. Although a few
species are harmless or even useful, most cause a nuisance by sucking blood from vertebrates
including humans. Accordingly, some authorities argue that disease-bearing mosquitoes are the
most dangerous animals on earth. With increasing reports of the harmful effects DEET has on
humans, there has been a move to repellents which are organic. These are of the kinds that have
had traditional household purposes before their being used as mosquito repellents.

Title: Anti Mosquito Repellant Candle Additive from Mandarin Orange (Citrus reticulata
blanco)
II. Objective of the Experiment:
1. This experiment will be conducted to know more the accurate and faster way of killing
mosquitoes that causes dengue.
2. To make an experiment that could really help the middle-class families as well as
everybody in avoiding to be sucked by the mosquito carrier of dengue.
III. Statement of the Problem: This study aims to determine whether extract from the peels of
mandarin orange (citrus Reticulata Blanco) can be a good additive for an anti-mosquito
repellant candle.
IV. Background of the Study:
Mandarin Orange (Citrus reticulata blanco) is said to have an essential oil from its
peels that is used as flavoring, perfumes and in medicinal use. An essential oil obtained
from the leaves and young twigs are called 'petit grain oil'. Yields are around 0.5%.
In traditional Chinese medicine, the dried peel of the fruit is used in the regulation of ch'i,
and also used to treat abdominal distension, and to enhance digestion. All that mandarin
eating adds up to a lot of peels. As you would expect, pesticide, herbicide and fungicide
residues are highest on the peel of oranges. The fruit, including its peel is used to treat
allergic reactions. Another important part of the peel that is widely used is the oil present in
it. It acts as an effective insect repellent and is also used in the production of furniture
polishes. The peel initially tastes somewhat sweet and spicy but has a bitter and pungent
after-taste.
An insect repellent is a substance applied to skin, clothing, or other surfaces which
discourages insects (and arthropods in general) from landing or climbing on that surface.
Insect repellents help prevent and control the outbreak of insect-borne diseases such
as malaria, Lyme, dengue fever, bubonic plague, and West Nile fever. Pest animals
commonly serving as vectors for disease include the insect’s flea, fly, and mosquito; and the
arachnid tick. So, in this case, we used candle as an insect repellant to kill mosquitoes that
causes dengue.
V. Hypothesis:
We can say that extract from the peels of mandarin oranges will help us to have a more
accurate and faster means of killing mosquitoes, due to high acidity this can help as an additive.
VI. Methodology
Materials:
Used Candles
Candle Wick
Mandarin Oranges
Pan
Candle Molder
Container
Mosquito Net
Procedure:
Collecting Mosquitoes
1. First, we filled the container with water depending on the container where you will make
the experiment.
2. Second, we will wait until we find some mosquito eggs(wrigglers).
3. Then, we covered it with fishing net.
4. After which, we just waited for the wrigglers to fully developed into an adult mosquito.
Candle with Extract of Mandarin Orange Making
1. First, we need to gather all the materials for the candle making. These are the candles,
and mandarin oranges.
2. Second, we extracted the peels of our mandarin oranges (Citrus reticulata blanco)
3. Next, we’ll going to cut the candle, but make sure we’ll get the candle wick of it.
4. Then, we will melt the candle in the pan with a moderate temperature.
5. After the candle has been melted, we will mix the melted candle with the extracted
peels of our mandarin oranges (Citrus reticulata blanco).
6. Let the mixture, blend properly.
7. Then we
in a candle
8.
will put our mixture
mold.
Finally we allowed it to dry
up.
•
VII.
For the final procedure, after we have collected mosquitoes and made our
candle, we can now test and light up our candle with our mosquitoes. Ifyou
can’t believe in this, use an ordinary candle and light it up for one day at a place
that is full of mosquitos and the next day light up a candle with the peels of
mandarin orange (Citrus reticulata blanco) and see the difference.
Observation:
We have observed that our anti mosquito repellant candle additive from mandarin
orange is a good anti mosquito repellant because it kills mosquitoes rapidly. As we light up
our candle, mosquitoes, die faster. the scent of the mandarin oranges helps the candle to be
more effective as an anti mosquito repellant candle.
VIII.
Conclusion:
Therefore, we conclude that extract from the peels of mandarin orange (Citrus reticulata
blanco) can be a good additive for an anti mosquito repellant. It could be one of the best
product of country for avoiding dengue if possible to be sold on markets, it could be
cheaper and effective. With this great idea, middle-class family could avoid mosquito
without paying higher on buying repellants ,it will be a great difference to everyone as
well.
