Abstract

When analyzing the effects of a vegetable extract substitution on chocolate cupcakes,

the results were not promising. The purpose behind the experiment was substituting an

ingredient with similar raw ingredient properties (such as powders for this experiment),

while changing the flavor profile. The theory was thought that the physical properties of

the cupcakes would not vary, but the flavor might. This was done to test the importance

of mouth feel in cupcakes and other more fattening foods. The physical tests done were a

texture analysis, viscosity on the batter and water activity measurements on the final

product. There was also a sensory panel to see if possible consumers would not the

difference in the taste of the variables. It was found that while the physical properties

were attempted to stay the same, using the same procedure, they did vary; however, the

main finding was in the sensory study. It was found that the audience still preferred the

control, chocolate cupcake over all the variables. While the vegetable extract substitution

might provide for a healthier snack, it is not preferred.

Introduction

With movies such as Fast Food Nation, Americans have been starting to notice their

diet trends, and might even admit that they are not as healthy as what they want or should

be. With all the delicious fattening food out on the market, it would be great if something

could taste just as great as dessert, but also be healthy and beneficial. The theory behind

the experiment is adding vegetable extracts to cupcakes will produce no change in the

product texture, water activity or taste preference. While measuring the effects on

texture, flavor and batter thickness, zucchini, carrot, pumpkin, jalapeno will all be

substituted for cocoa in chocolate cupcakes. The purpose of adding vegetable extracts to

cupcakes not only takes a dessert food and makes it healthy, but it adds more vegetables

into the diet of Americans.

Unhealthy diets are a trend that is growing rapidly among children, as well as adults.

It is recommended that we should be consuming at least two servings of fruits and three

servings of vegetables daily (Nebeling 2007) for a healthy diet; however, there is a report

that over time, the majority of U.S. adults continue to consume fewer than five servings

of fruits and vegetables daily (Nebeling 2007). This is upsetting because there is an

increasing trend in obesity and weight gain. Just in 2001, a study was shown that by

2001, almost 21 percent of adults were obese, representing a nearly 75 percent increase

(Salinsky 2003). This project is to help provide healthy alternatives to unhealthy foods,

starting with the cupcake.

Vegetables are an important food group that often gets overlooked. Sometimes it is

due to the fact that they might be the least appetizing. Or maybe it is because vegetables

are usually served by themselves and not mixed in with some of our favorite foods.

Vegetables are important because Vegetables provide a selection of important vitamins

and minerals along with other compounds, called phytochemicals that help to keep us

healthy (Hirving 2007). Another reason why vegetables are healthy and an important

necessity of a diet is it was found that subsets of the population who consume larger

amounts of cruciferous vegetables are afforded some degree of disease protection (Lunn

2006). The amounts that Americans should be consuming are in the current guide lines

suggested adults should eat at least 5 portions (400g) of a variety of fruit and vegetables

each day (Hirving 2007). But sometimes it is hard to achieve the recommended 5

portions of fruits and vegetables a day. That is why adding vegetable extract to cupcakes

will increase vegetable portions and also deliver a mouth watering treat.

Seeing how vegetables are an important, but sometimes overlooked, food, there is

much discussion on how to help vegetables play a more dominant role in diets. In an

article by J. Lunn, little has been done up until now to encourage the consumption of

fruits and vegetables, which have long been known to be essential for good health (Lunn

2006). The article goes into more detail about the use of a “superfood” and gives possible

definitions of it. In the talk about a “superfood”, one definition is the most well-known

definition of a superfood elates to the fruit and vegetable section of most supermarkets

(Lunn 2006).

The theory is that perhaps people, children especially, are addicted and drawn to

unhealthier foods because of their physical properties. Flavor and appearance just need

to be satisfactory as long as people assume they are eating something that feels good

when they eat it. Mouth feel is the technical term food scientists use to describe how

food feels in your mouth (Szczesniak 2005). The texture analyzer is used because it can

measure the force in compression with any kind of food (Daniels 2003). It is important

to measure the texture because this can help dictate the mouth feel of a food.

Using water activity measurements were useful in numerous ways. Water activity is

defined as measure of the energy status of the water in a system (Carter 2007). The role

that water activity plays in food is that water activity decreases, or as water becomes

more “bound,” the water in a system is less available for microbiological and chemical

reactions, which can impart stability to a food system (Carter 2007). This means that in

order for the food to be shelf stable and not be affected by molds, yeast or bacteria, a low

water activity is preferred. Low water activity also inhibits chemical activity as well.

Water activity is dependent on the temperature (Carter 2007); therefore, it is important to

record the temperature along with the water activity value. It is important to monitor the

water activity in order to control the retardation of the staling process (or perceived

freshness of the baked good) (Tessier 2001). The water activity aids in the main physical

property, texture, by observing how high the water activity is. The higher the water

activity, the product will have a softer crumb (Tessier 2001). The role that water activity

plays in cupcakes is that if vegetable extract substitution is successful, it still must

maintain microbial and chemical properties as well to be considered safe for consumers.

Adding in vegetables in cupcakes will give a healthier product to the market, but will

consumers want to buy it and will it play a definitive role in their health? In a study

conducted by Lassen and colleagues in Denmark showed an increase in fruit and

vegetable consumption at lunchtime in five worksite canteens when these foods were

made more easily available and appealing (Buttriss 2004). This study proves that people

will eat healthier if there is more availability of healthy foods. While the article goes on

to recommend price changes of food and even counseling, it can also be concluded and

recommended that vegetables need to be made more attractive and available to

consumers.

The project of The Effect of Vegetable Extract Substitutions to Cupcakes will be

focused on reproducing a well known product, cupcakes, with healthier additions,

vegetable extracts. While the trials will be tested compared to the standard, there will

also be a sensory test to evaluate how well the other trials compared based on a nine point

hedonic scale. The null hypothesis is that there will be no difference between the

standard cupcake and the vegetable cupcakes.

Methods:

The design of the experiment was to take a known recipe for chocolate cupcakes and

substitute the flavor. The recipe used was chosen because the chocolate was in a powder

form. Since the vegetable extract was also in flavor form, it was assumed that little to no

change in the texture or physical properties would take place. The color of the powders

and flavor were the main targets of the experiment, assuming that the physical properties

had little variation. This would then help show how people prefer the mouth feel and

texture of a food while the flavor varies.

For the experiment of substituting vegetable extract into chocolate cupcakes, the

following recipe was used.

689.76 grams all-purpose flour

459.84 grams granulated sugar

114.96 grams variable (HERSHEY'S Cocoa, vegetable extract)

9.49 grams baking soda

4.745 grams salt

470 mL water

180 mL vegetable oil

30 mL white vinegar

10 mL vanilla extract

The variables used were zucchini powder, carrot powder, pumpkin powder, jalapeno

powder and the control was chocolate cocoa. The control was a Hershey product while

the vegetable extracts came from The Food Source Inc.

The oven was heated to 350°F. There were twenty-four muffin cups (2 1/2-inches in

diameter) with paper or foil bake cups lined inside two twelve cupcake trays. The dry

ingredients, flour, sugar, cocoa/vegetable extract, baking soda, and salt were combined.

In fact, most of the dry ingredients were pre-weighed and to shorten the baking

preparation. The wet ingredients water, oil, vinegar and vanilla were then mixed in large

bowl with the dry ingredients, and the mixture was thoroughly blended. The muffin cups

were then filled ¾ full with the cupcake batter. The cupcakes were baked 25 minutes.

The cupcakes were then cooled. The experiment was performed in the food chemistry

baking laboratory in Stone Hall. The room temperature was approximately 25ºC for all

three trials.

To test the different variables, the viscosity was measured at room temperature (25ºC)

using the Brookfield viscometer with spindle number 7 at 60 RPM. Once the cupcakes

were baked then cooled, the crust was taken first, then the body of the cupcake was taken

for a water activity reading using the water activity system. While the water activity

system was stabilizing and finding a reading, the texture of the cupcake was found using

the Stable Micro Systems Texture Analyzer with the cone probe. Since the cupcake had

different texture levels, there were at least three replicate samples taken for each trial.

The viscosity and texture were also measured in a room at room temperature (25ºC).

Once the tests were finished, the cupcakes were then dispersed to a sensory panel. The

panel was chosen at random, and there were seven panelists for each trial. The panelists

rated the cupcakes on appearance and overall (flavor and mouth feel) using the nine-point

Hedonic scale, then the panel rated the cupcakes in order of preference one to five; one

being their favorite, and five being their least favorite. Altogether, only three trials were

done on separate days for the experiment.

The original recipe can be found at Cooks Recipes

http://www.cooksrecipes.com/cake/easy_bake_shoppe_cupcakes_recipe.html

The replications were done on separate days in case human and preparing error played

a crucial role. The reason replications were done on separate days was to try to minimize

any error and allow the preparer to take time making and baking the cupcakes. The

people chosen for the sensory panel were chosen based on physical proximity. Those

who were in the laboratory while the physical properties were being tested usually

sampled the cupcakes. No person sampled the cupcakes twice. People who were also

asked to sample were those collegiate students in the Purdue Society of Women

Engineers since they typically had an event on an evening that a replication was carried

out. Also, those who did participate in the sensory panel did not know the variables of

the cupcakes until afterwards. This was to avoid any preconceived opinions. The typical

panelist was a college student of age 18-22. This is not the targeted demographic;

however, it is still important to get the general audience’s opinion.

Discussion

The focus of the experiment was to attempt to have the variables match or come close

to the physical properties of the control. This was measured by a texture analyzer,

viscosity of batter and also water activity. There was a control used in the experiment,

because the chocolate cupcake’s physical characteristics were trying to be replicated.

The tests performed were aimed to deviate very little from the results of the control. The

texture analyzer was done to give a better idea of the mouth feel of the cupcakes. Water

activity was used to control the microbial/safety aspects and also the quality. The

viscosity of the batter was used to see when the chemical changes started to take place,

pre-baking or during baking. If the viscosity of the batter was consistent with the control,

but the texture analysis was different, this leads to the conclusion that the baking

conditions played a role in the experiment. Table 1.1 and Figure 1.1 compares the

thickness of all the batters. Figure 1.1 shows that zucchini powder is the most similar to

the control, but the other variables are not too close to the control. This could be due to

the composition of the vegetable powders compared to the cocoa powder. Right away it

is seen that the results will not be favorable since the substitution impacted the physical

properties.

Table 1.2 and Figure 1.2 show the results from the Texture Analysis. The control has

the highest texture which means it is the strongest since more force is required to

compress the product. Since the other variables have a lower Texture force, this could

mean that they need more baking time, and a more appropriate bake time and temperature

should be reviewed and recommended. It could also mean that regardless of flavor,

consumers could still favor the control because it has the consistency that is on the

market. There is also a wide range of values for texture. This could be do to the

equipment since there were some technical difficulties while running the trials with this

machinery. It could also be due to the time when the texture analysis was performed. If

the cupcakes were not cooled, they would yield a lower texture analysis because they are

still hot and soft.

An observation made during the procedure was that those cupcakes that had a higher

difference in water activity from the crust and body of the cupcake could be due to

cooking time. Some cupcakes had very similar water activity, which also led to the

visual observation that those cupcakes had a weak crust. The pumpkin cupcake did

appear to be softer and more moist than the other variables. Having similar water

activities throughout the cupcake could lead to the conclusion that it was not cooked as

long as necessary; however, the data for the control results refute that theory. The

control, which had the highest force for texture, did not have the largest difference in

water activities between the crust and the body of the cupcake. If there is a link between

cook time and water activity difference, more testing would be needed. Another point of

interest is comparing the variables values to the control while using Figure 1.3. It seems

that the zucchini and jalapeno are the closest variables to the control. This could also

show that by having differences in the water activity, the texture of the crust compared to

the body could be observed.

Table 1.4 shows the data from the water activity results. These results could not be

averaged due to the temperature dependency of the results. All the results have a

different temperature that they were taken at, which does not allow the data to be

standardized. Since the purposes of the water activity results were to observe the safety of

the food, it can be seen that the food products have a higher water activity than some

foods. This could lead the cupcakes susceptible for yeasts and mold.

A source of error could be done by the preparer of the experiment. Until the

experiment had been carried, little to no knowledge and practice of the equipment had be

demonstrated. A recommendation would be for the experiment to be carried on with

trained professionals who are better trained to work the equipment. The large standard of

deviation values could be due to the human error in working the equipment.

The subjective methods were done by two methods. The first method that the

cupcakes were evaluated at was the nine-point Hedonic scale. Figure 1.4 show the results

from the overall characteristics of the cupcakes. This includes the flavor, mouth feel and

even aroma of the product. The results show that the most favored variable was the

control. Figure 1.5 shows the results from the appearance only evaluation. Once again,

the control is favored among the other variables. The reason that appearance was done

separately from the overall evaluation was that while preparing the cupcakes, it was

observed that the powder had some color to it. While the zucchini and jalapeno could

have been pleasing flavor-wise to a consumer, a green cupcake was not aesthetically

pleasing. To eliminate another variable such as appearance, it was rated separately so as

to provide data based on appearance alone.

The second method to evaluate the sensory portion of the experiment was to rank the

variables in order of preference. Once again, overall characteristics were ranked, then

appearance. The rank was one to five with one being the most desired cupcake and five

being least favorite. Both Figures 1.6 and 1.7 show that the control was ranked as the

most preferred cupcake, both on overall and appearance properties. This shows that the

vegetable substitution proved that it did have an effect on texture; therefore, also having

an effect on flavor and consumer likeableness. This coincides with a study that was done

on children with eating disorders. It was found that altering food type and texture may

alter the aversive or reinforcing properties of eating in other ways (Patel 2002).

The subjective portion of the experiment could be due to human and instrumental

error. Since the target age demographic is children, children should be used on the

sensory panel. Another approach to the sensory panel would be to use trained food

tasters can be surprisingly accurate and consistent when it comes to rating such properties

on scales of, say, 1 to 10 (Szczesniak 2005). Another way to analyze the texture of food

to flavor is to correlate these subjective sensory ratings with objective measurements of

the way food samples flow and deform when a force is applied, a branch of physics

known as rheology (Szczesniak 2005).
