Percent Composition Of Gum Lab Report

647 Words3 Pages

Purpose: The purpose of this lab is to find the percent composition of sugar in gum, and how it differs based on the brand of gum, by using the percent by mass. Hypothesis: If two separate brands of gum are masticated, in which is based on Trident and Orbit Gum, then the mass of the sugar/the percent composition of the sugar in the gum would be the same, because the amount of sugar and sugar alcohol used in the gum are the same, based on the nutritional facts provided. Variables: Independent Variable: The Brand of Gum Dependent Variable: Percent of Composition of Sugar in Gum / Mass of Sugar (in g) Controlled Variables: The Amount Sticks of Gum, The Flavor of the Gum, Materials: ~ Trident Gum (2) ~ Wrapper of Gum ~ Calculator ~ Orbit Gum (2) ~ Weighing Scale / Balance Procedure: 1) Gather Materials 2) Weigh and record the mass of the gum in the wrapper 3) Remove the gum from the wrapper, and weigh/record the mass of the wrapper alone - Subtract to find mass of gum itself 4) Have 2 sets of 2 people masticate the gum. Each set of people should receive a different brand 5) Chew until the gum “loses” its flavor - approximately 5 minutes. All people should remove the piece of gum at same time 6) Attempt to …show more content…

The experiment conveys how the percent compositions of the sugar in the brand sticks of gum were different, even though the nutritional facts portrayed that the sugar content should have been the same. Based on the data, it is determined that Trident has a lower composition of sugar in the gum, in relation to Orbit. This is shown, as after 5 minutes of chewing the gum, the total mass of Trident dropped by .94 grams whereas the mass of Orbit gum dropped by 1.18 grams. The percent sugar composition in the Trident gum was 50% whereas Orbit had a sugar composition of

Independent Variable amount of substrate (sucrose) present 3. Controlled Variables temperature, pH, sucrase + sucrose incubation time 4. Describe what is measured as an indicator of sucrase activity and why this is an indicator of sucrase activity. I believe glucose and fructose was used as an indicator because they are what produces sucrose and sucrose creates more sucrase activity.

Throughout the history of advertising there have been many emotional commercials. Commercials that emphasize a relatable and powerful main idea that is subtly, or not so subtly, woven in with the product that is being advertised.

As my experiment, I tested 4 students by giving two of the four students a piece of spearmint gum and two students no gum during the test. The students with the gum both averaged a 97. Georgia scoring and 97, and Chloe also scoring a 97. The students who did not have a piece of gum during the test both averaged a 94. Emma scored a 100 and Mackenzie scored an 88.

Our hypothesis is that the homemade lip balm is going to be better than store bought. We think this because you can add different ingredients to make the homemade product look, feel and taste better. Intro Is making your own lip balm and cosmetics cheaper and easier than buying them at your local drugstore? We will find out! We will be making 3 different kinds of lip balms and comparing them with a store-bought lip balm.

Remaining a constant routine or schedule during the experiment is very difficult to achieve therefore allows for other variables within the procedure that are not intended. Potential sources of error could be eating or drinking too soon before class or at a different time than usual. Forgetting to follow the procedure or irregularly following the procedure could affect the results for the data. In future experiments, I would increase the amount of times the gum and mints are taken to possible have a greater change in the experimental values. Having more participants would create a better average and allowing better results for conclusions.

Based on the Beer-Lambert Law, the absorbance of light of a sample is directly proportional to the concentration of the molecule which absorbs light. Distilled water is used as a blank solution to set the spectrometer to a zero reading due to none of the absorbing species present in the solution tested. In this experiment, heat is used to speed up the browning of reducing sugar to produce furan. It is due to the chemical reaction of the reducing sugar with the free amino group of an amino acid. The amino group that is present in monosaccharides sugar are a short chain, therefore it is more reactive.

The magnitude of p-value indicates that linear terms of AF and SMP have significant effect at 5% level of significance (p <0.05) on cookie’s fiber content. Further quadratic effect of AF and interaction between ‘AF and SMP’ has significant effect at 5 % level of significance (p <0.05) on cookie’s fiber content. The magnitude of β coefficients revealed that the linear term of AF has the maximum negative effect (β= -0.22) whereas SMP (β= 0.03) showed a positive effect on cookie’s fiber content. The increase in fiber content with decrease in AF may be due to the increase in FTMF proportion in formulation which has high initial fiber content than AF.
