Believe it or not one of the most common carbohydrate that is
being consumed by Americans today is starch (Livingstong.com). Starch is the
type of carbohydrate that is found in many staples of food groups, from cereals,
rice, potatoes, and even wheat. Since starch is so prevalent in different types
of food that we consume daily, the researcher decided to complete a science
project focusing on “Which household food items out of apples, bread, white
potato’s, cheese, milk, uncooked and cooked pasta contains the most starch”.
The purpose of this experimentation is to test for the
presence of starch in everyday food items that are found in our kitchens.  This project
is important to the researcher because it makes others aware of how much starch
their everyday household food items really contains. The researcher believes
it’s important that we are more aware of what we are putting in our bodies.  During this investigation the researcher will
detect starch in everyday foods using iodine. Iodine
will change from an orange/brown color to blue/black if starch is present. This
happens when the starch molecules form a spiral and help the iodine molecules
to line up. The
researcher hypothesize that white potato, cooked pasta, and bread will contain
the most starch out of the apple slices, milk cheese and uncooked pasta.

But what are carbohydrates? Carbohydrates are one
of the four major biomolecules that an organism needs from structure to
function for energy ( NHS choices). Starch is a carbohydrate, or a long chain
of glucose (sugar) molecules stuck together by chemical bonds. All plants make
starch, but some contain more than others. Carbohydrates indeed are one of the main
sources of our daily diet (Healthline). Carbohydrates are our bodies most
important and readily available source of energy. When consuming food,
your body utilizes
the starch carbohydrates it
needs right away and then stores the rest as glycogen in your liver and muscles (Healthline).
Glycogen can be pulled for energy for later use when your system needs it. For
example, your body may
burn glycogen during a workout if you
do not eat before a meal. This
biomolecule plays a vital role in both kids and adults healthy diet.

Carbohydrate are classified as either
simple or complex.  What makes
carbohydrates simple is that they are composed up of either one or two sugars
and are classified as a monosaccharide or a disaccharide (Healthline) . Complex
sugars on the other hand are composed up of three or more sugars and are
classified as a polysaccharide (Healthline). Carbohydrates are broken down
differently in the human body depending on the type that is being digested. Starchy foods are an important source of energy. After
they are eaten, they are broken down into glucose, which is the body’s main fuel, especially for our brain and muscles.
Starchy foods provide important nutrients to a person’s diet for example starch serves as
a great source of B vitamins, iron, calcium and folate (NHS choices).

In-order
for this experiment to be conducted there was certain materials required by the
researcher.

1 bottle of iodine
solution

1 bag of apple slices

1 cup of milk

2 slices of bread

1 cup of uncooked
pasta

1 cup of cooked pasta

1 cup of white potato
slices

1 cup of yellow
shredded cheese

1 eye dropper

9 small disposable
plates

1 roll of paper
towels

1 set of gloves

 

Before
starting this experiment, the researcher made sure he had a clean workspace
where he was able to display all the materials needed for the experiment. The
procedures for this experiment was very simple procedures that went as
followed.

1.      Number and label each
disposable plate with the name of the sample food item.

2.      Place one of each
food item on its correct disposable plate

3.      Before testing each
food sample record on data sheet whether the researcher think it contains
starch or not.

4.      Using the eye
dropper, place a few drops of iodine onto each food sample one at a time and
observe to see what the color change will be.

5.      Record your results
in the data table.

6.      Complete steps 2-5
for all food samples.

7.      Complete 2 trials for
each food sample for accuracy.

 

The researcher completed this
project focusing on “Which household food items out of apples, bread, white
potato’s, cheese, milk, uncooked and cooked pasta contains the most starch” to
make people aware of the presence of starch in everyday food items that are found in our
kitchens. 
This project was important to the researcher because it helps make
others aware of how much starch their everyday household food items really
contains. The researcher believes it’s important that we are more aware of what
we are putting in our bodies. This project will not only benefit the researcher
but everyone who believes in living a healthy and long life. The researcher
would like to thank his mom and dad for purchasing all the materials to
complete this project as well as his cousin for helping him complete this
experiment.

            The researcher hypothesis turned out to be incorrect in
this experiment. Uncooked pasta did not contain any starch. The researcher
tested his hypothesis twice and both times it was concluded that the only items
that contained starch were the white bread, white potato, cooked pasta and uncooked
pasta. The apple slices, milk and cheese did not contain any traces of starch.
This was determined after comparing the color before and after drops of iodine
was placed on the sample food items. If the researcher had to complete this
project again the one thing he would do differently is test a variety of more
food items as well as see what type of biomolecules are present.
