QUESTION 13 25 points SaveAnswer Now that you have the ice cream mix you want to try to freeze it into ice cream. You made 100 pounds of ice cream mix at a moisture content of 62%. You discovered that the ice cream mix's specic heat above freezing is 0.74 BTUIIb F, its specific heat below freezing is 0.40 BTUIIb \"F, and its freezing point is 27.3\"F. The latent heat of water is 144 BTU/lb. If the initial temperature of the ice cream mix was 40F, how much energy (BTU) needs to be removed to freeze all ofthe ice cream mix (assume all of the water freezes in the production of this ice cream) to a temperature of 18F. Please provide your answer to the nearest whole number. QUESTION 12 10 points Save Answer Food scientists often thermally process food products to reduce the potential microbial population. What if, prior to going home for the evening, you thermally processed the ice cream mix (from question 11) that originally contained the 10 food infection type microorganisms. If the D-value for the mix is 2.87 minutes at 140 C and you processed the mix for 20.09 minutes, what would the final microbial count be?QUESTION 11 20 points Save Answer You decided to become a super cool food scientist and upon graduation, was hired at an ice cream company. The first product you are asked to work on is soft-serve ice cream. Soft-serve ice cream starts off as a liquid ice cream mix that will later be frozen into delicious, smooth and creamy ice cream. Your lab mate was showing you how to make the liquid ice cream mix, and after making it, forgot to put it in the refrigerator before heading home. Unfortunately, that ice cream mix contained 10 viable food infection type microorganisms. If the average lag phase generation time is 120 minutes, the average log phase generation time is 60 minutes, and two generation times (40 microorganisms) are required for the system to switch from the lag to the log phase, how many microorganisms would be present in the mix when you returned to the lab 15 hours later. Please provide your answer to the nearest whole number. QUESTION 10 5 points Save Answer Keeping with the information noted in question 9 (reminder: After baking, you would like each of your cookies to be 8cm in diameter You deCided to utilize process control charts to optimize your cookie making process, so you selected 5 baked cookies and measured their diameter, and obtained the following measurements (in cm)): 1,83 2,81 3,78 4,79 5,80 684 What value will you plot on the range chart? Please provide an answerio the nearest tenths place (i.e., 1 deCimal place) QUESTION 9 15 points Save Answer After baking, you would like each of your cookies to be 8cm in diameter. You decided to utilize process control charts to optimize your cookie making process. For the first point you plot on your X-bar chart, you select 6 baked cookies and measure their diameter. You obtain the following measurements (in cm): 1. 8.3 2. 8.1 3. 7.8 4. 7.9 5. 8.0 6. 8.4 What value will you plot on the Xbar chart? Please provide an answer to the nearest tenths place (i.e., 1 decimal place)
