The Process Of Frying Food Changes Its Quality Texture And Color Suppose The Total Change In Color E Which Is Measur 1 (29.28 KiB) Viewed 28 times

The process of frying food changes its quality, texture, and color. Suppose the total change in color E (which is measured in the form of energy as kJ/mol) of blanched potato strips can be estimated by the function below, where C is the temperature (in ∘C ) and t is the frying time (in min). Complete parts a through c. E(t,C)=436.36−10.93t−5.69C−0.02t2+0.02C2+0.08Ct a. What is the value of E prior to cooking? (Assume that C=0.) E=436.36 kJ/mol (Type an integer or a decimal.) b. Use this function to estimate the total change in color of a potato strip that has been cooked for 4 minutes at 170∘C. The total change in color is 57.42 kJ/mol. (Type an integer or a decimal.) c. Determine the critical point of this function and determine if a maximum, minimum, or saddle point occurs at that point. The critical point is at (t,C)= (Type an ordered pair, using integers or decimals. Round to two decimal places as needed.)
