Sugars, especially glucose, are a major source of energy for all living things. Plants produce glucose by photosynthesis and convert that and other monosaccharides into various disaccharides such as sucrose (table sugar) or convert it into starch to store it more easily. Animals which eat these plants can make use of this energy source and also are attracted to the sweet taste and smell. We frequently add sugar to foods that normally and naturally do not have it (or have it only in small quantities) just because we crave the taste of it for its own sake. As our sugar consumption has risen in western nations, so have our rates of the “stress” diseases: diabetes and hypoglycemia, heart and circulatory problems, dental caries, malnutrition, decreased resistance to infections, etc.
Around 100 years ago, the average American consumed about 40 lb. of sugar per year. As of 1986, Americans were averaging a third of a pound of sugar per person (including children) per day, which comes to about 127 lb. per person per year. As of 1982, 25% of the average American’s intake of cane and beet sugar came from soft drinks. Soft drink consumption in the U. S. rose from 1.6 drinks per person per year in 1850 to 620 drinks per person per year in 1981.
As of 1998, the average American sugar consumption has risen to 148 lb. per person per year, which is over 1/3 lb. or 600 Kcal per day! According to a study by US Department of Health and Human Services, between the years, approximately half the US population consumes sugar drinks on any given day with 52% of the population consuming at least one 12- oz cans of soda per day. In this experiment, we will analyze a number of types of soft drinks to see how much sugar they contain.
Objective: To determine the amount of sugar in sodas or other sugar containing beverages by extrapolating from graphical data. The data we will graph is the average solution density versus mass % sugar in sugar solutions.
Background: Density is defined as the ratio of a substance’s mass to its volume, as shown in Equation 1. Equation 1 density, g/mL = mass, g / volume, mL. We can calculate the density of a sugar solution, once we have measured the mass of a known volume of the solution. As the amount or mass of sugar increases, so does the density of the solution. We can express the amount of sugar in the solution in terms of mass percent, as shown in Equation 2. Equation 2 mass percent sugar, % = (mass of sugar, g / mass of solution, g) x 100%

The escalating consumption of sugar, particularly in the form of soft drinks, has profound health implications, making it crucial to understand and quantify sugar content in beverages. This paper explores a methodology to determine the sugar concentration in sodas through density measurements and graphical analysis, providing an accessible approach for both educational and practical applications.
Introduction
Understanding the sugar content in beverages is essential given the global rise in sugar consumption and related health issues such as obesity, diabetes, and cardiovascular diseases (World Health Organization, 2015). Traditionally, sugar content analysis involves laboratory techniques like titration or chromatography, which, while accurate, may not be feasible in all settings due to resource constraints. Alternatively, density-based methods offer a practical approach for estimating sugar concentration, leveraging the correlation between solution density and sugar content (Davis & Smith, 2018).
Theoretical Background
Density is defined as the mass per unit volume of a substance (Eq. 1). When sugar dissolves in water, it increases the solution's density proportionally to the amount of sugar present (Evans, 2019). The mass percent of sugar (% m/m) is calculated as the ratio of sugar mass to the total solution mass, multiplied by 100 (Eq. 2). Establishing a linear relationship between density and sugar concentration enables the estimation of sugar content in unknown samples through graphical analysis.
Methodology
The experimental procedure involves preparing sugar solutions of known concentrations, measuring their densities, and plotting these data to generate a calibration curve. The process begins with dissolving specific amounts of sugar in distilled water to create solutions with various known sugar percentages. The mass and volume of these solutions are precisely measured, and their densities are calculated. A graph of density versus mass % sugar is then plotted, and linear regression analysis determines the trend line equation.
To analyze commercial beverages, samples are measured for volume, and their densities are calculated similarly. Using the established calibration curve or trend line equation, the mass % sugar of the beverage samples is estimated. This approach provides a rapid and cost-effective method for assessing sugar content without advanced laboratory equipment.
Results and Data Analysis
The calibration curve generated from the known sugar solutions typically exhibits a linear relationship, with the density increasing as the sugar concentration increases. The slope and y-intercept of the trend line provide a mathematical model to estimate the sugar percentage from the measured density of beverage samples (Holland et al., 2020). For example, an unknown soda sample with a measured density of 1.015 g/mL might correspond to a specific sugar concentration based on this model.
Discussion
The correlation between solution density and sugar content validates the usefulness of density measurements as an indirect indicator of sugar concentration in beverages. However, several factors can influence the accuracy of this method, including temperature variations, presence of other solutes, and degassing of carbonated drinks (Li & Chen, 2021). Degassing, in particular, reduces carbon dioxide content, impacting the density measurement. It is essential to standardize measurement conditions and account for these variables for reliable results.
Moreover, this method aligns well with nutritional labeling, enabling consumers and health professionals to estimate sugar intake from beverages rapidly. The approach also demonstrates educational value, illustrating principles of solution chemistry, density, and data analysis.
Conclusion
Measuring the density of sugar solutions and using graphical analysis provides an effective means to estimate the sugar content in sodas and similar beverages. This technique is accessible, economical, and suitable for educational purposes, fostering a better understanding of beverage composition and its health implications. Future work may focus on refining the calibration models and exploring automated analyses for broader applications.
