Question

(made it shorter)

1. Calculate the grams of each type of fat per serving of your food (percent X total fat per serving). Compare these to the values provided on the food package label. Keep in mind that the values on the food packaging labels are reported only to the nearest 0.5 grams. (photos on bottom)

2. How do your experimental results compare to the labeling of the snack food? Provide a detailed and specific analysis. (photos on bottom)

Explanation / Answer

1.) Using the formulas given in the table. The percentages of fat can be easily calculated as
unsaturated: 74.3%
saturated: 25.7%
polyunsaturated: 2.97%
monounsaturated: 71.3%

Since the total fat content per serving is 5 g, Then the amunt of fat per serving if the sample can be calculated by multiplying the percentages by 5 g. The results are rounded off to the nearest multiple of 0.5 g

unsaturated: 4.0 g (originally 3.71g)
saturated: 1.0 g (originally 1.28g)
polyunsaturated: 0.0 g (originally 0.15g)
monounsaturated: 4.0 g (originally 3.57g)

2.) Compared to the values indicated in the nutrition facts, some results are close to the values while some of the results deviate largely maybe due to the type of analysis done by Pepperidge Farm such as by Soxhlet extraction and/or gas chromatography
