The purpose of the laboratory is to provide a detailed overview of the pasta cooking process and assess various processes. The main method used to cook pasta is by immersion in boiling water or brine solution. Accordingly, this laboratory makes use to a pot, a stove, thermometer, water, boxed pasta, and other standard kitchen ingredients like salt. The main result is that pasta cooks faster in boiling brine solution compared to boiling water. Introduction This laboratory module provides a demonstration of cooking pasta for dinner through the process of boiling in water and a brine solution, culminating in a determination of which method takes the least time. Objectives The main objectives of this laboratory module are 1) obtain the temperature evolution over time of water and brine solution from room temperature to boiling, 2) determine the amount of time it takes to cook the pasta after boiling, and 3) evaluate which method of cooking pasta is more time efficient. Background and importance Cooking pasta has been around for centuries and is ubiquitous in the modern western world. As a matter of fact wheat semolina has long been considered a central component of food, notably in pasta products (Laleg, Cassan, Barron, Prabhasankar, & Micard, 2016). More directly related to this laboratory, pasta is a typical food that is cooked and consumed by college students across the globe in unprecedented numbers. Therefore, knowledge of the fastest common method for cooking pasta should enable students to save time and spend that time studying. Procedure The process of cooking pasta through immersion in boiling water or brine is fairly straightforward. First, two pots of adequate size to contain the amount of pasta plus liquid is obtained. Both pots are filled with 1 quart of water, and standard table salt is added to only one of them, the other remains a control with only plain water. Next, both pots are placed on the stovetop and the initial temperature is recorded, please see details in Appendix A. For both pots, the fire lit, and set to medium. While heating up, the temperature is taken every minute. Once the liquid boils, 1 cup of pasta is added, please see details in Appendix B. Starting after five minutes, and repeating every minute samples are taken, air cooled, and then sampled to check to see if the pasta is finished cooking. Once the pasta is finished cooking, the heat is turned off, and the water drained from the pasta by using a strainer. 3 Original Data Sheet 4 Results and Calculations 240 110 220 100 200 90 Temperature (C) Temperature (F) Figure 1a shows the measured temperature history, in Fahrenheit, during heating for both the water and brine solutions. The conversion between degrees Fahrenheit and Celsius is given by 5 °πΆ = (°πΉ − 32) , 9 and as an example, the standard boiling point of water, 212F, is readily converted to 5β 5 (212β − 32β) = (180 ) β = 100β. 9β 9 Using this conversion, Figure 1b shows the converted temperature history, in Celsius, during heating for both the water and brine solutions. Additionally, the data shows that the pasta is cooked after 10 minutes in plain water, and after 8 minutes in the brine solution. 180 160 140 120 100 70 60 50 40 80 60 80 30 Water Brine 0 2 4 6 Time (min) a) 8 10 12 20 Water Brine 0 2 4 6 8 10 12 Time (min) b) Figure 1: Measured temperature as a function of time while heating both water and brine solution, a) in degrees Fahrenheit, and b) in degrees Celsius. Discussion To reiterate, the main objectives of this laboratory module are 1) obtain the temperature evolution over time of plain water and brine solution from room temperature to boiling, 2) determine the amount of time it takes to cook the pasta after boiling, and 3) evaluate which method of cooking pasta is more time efficient The results, as shown in Figure 1 clearly show the temperature history of plain water and brine solution. Both water and brine start at room temperature and under the application of heat the temperature increases nearly linearly. The plain water, near the boiling point, remains at a constant 212F while the liquid changes phase to water vapor. This clearly shows that plain water boils at 212F, which is inline with common knowledge. Additionally, the brine solution exhibits no clear plateau, which indicates that the water in the solution changes from liquid to vapor, and the salt remains in the residual solution. This shows that the brine solution boils at a higher temperature compared to plain water, which is also expected based on common knowledge. 5 Additionally, the results show that pasta cooked in plain water takes 10 minutes to cook, while pasta cooked in the brine solution takes only 8 minutes to cook. This result indicates that cooking pasta in a brine solution is faster than plain water. In this case the overall savings in time is 20%. This reduced cooking time may be explained by the increased boiling point of the brine solution compared to plain water causing the 20% increase in efficiency. Overall the data appears to be of high quality, reliable, and without obvious errors. This assessment is made since the boiling data matches well with common knowledge. Conclusion In conclusion, the results show that cooking pasta in brine is 20% more time efficient compared to plain water. Additionally, all the objectives have been met: temperature evolutions, and cooking times were measured; and we have determined cooking in a brine solution is more time efficient than plain water. Satisfying each objective yielded information that was integral in drawing the final conclusion. Questions and Answers Question 1: What is the boiling temperature of plain water? Water boils at 212F, which is equivalent to 100C (Black & Kosher, 2019). References Black, J., & Kosher, R. (2019). DeGarmo's Materials and Processes in Manufacturing (13th ed.).

Note that there is neither a heap nor a valley; the pasta is simply level with the top of the measuring cup. Figure 3: The pasta in a 1-cup measuring cup. Here are a few hints and tips that were used in the creation of this document, and are considered basic working knowledge of word processing software. ο· Note how the headings are done, this allows you to automatically create the table of contents. ο· Note how figure captions are done: Insert -> caption. This will allow you to cross-reference that caption in the text. It will then automatically update if other figures are added before/after. ο· Note how figures are inserted into a table (without borderlines) so you may include the “a)” and “b)” underneath subfigures. It also keeps nice alignment on the page. ο· Note how the references are done: Document elements -> references. This will allow you to automatically generate the references and cross-reference them in the text. Final caution, this document was created using Word for Mac 2011. There are probably numerous updates in the software since then. 7
