The protocol used for the Sprint rapid protein analyzer followed
the method outlined in the AOAC Official Method (2011.04) for
Protein in Raw and Processed Meats (AOAC, 2011). To prepare each
run, homogenized lean beef (0.3150–0.3300 g) was weighed into a
tared Sprint sample cup and then placed on the Sprint turntable. A
filter was then added to the turntable and the run began with a
homogenizer speed of 25,000 rpm for 90 s.
