. Conclusion
In conclusion, the Sprint machine has proven to be capable of
accurate and precise protein content determinations and it is a
relatively simple protocol to perform; however, in instances where
the accuracy of protein content determination is critical, or when
the sample is suspected to be outside the constructed standard
curve, better options would still be the Dumas or Kjeldahl
methods. Depending upon experimental requirements, the Sprint
Rapid Protein Analyzer could become a viable research option for
determining protein content in lean beef.
