Abstract
ABSTRACT Four moisture and four fat determination methods requiring from 5 min to 12 h were performed on 664 ground beef samples to compare accuracy and precision of rapid fat and moisture determinations to the Association of Official Analytical Chemists (AOAC) procedures. The modified Babcock results were closer to the official ether extraction method than those obtained from the Banco and Univex methods. Moisturefuge moisture determinations were more highly correlated with AOAC percentages than either the Toluene or Ohaus methods. Correlations among moisture and fat determination methods studied with official results were 0.90 or higher and none of the fat and moisture values differed significantly from those using AOAC methods. These data suggest the modified rapid moisture and fat determination methods evaluated have adequate accuracy and precision for reliable control and analyses use.
