For the range of fat content found in pork, the two chemical procedures studied for the estimation of intramuscular fat (IMF), Soxhlet and total lipid (TL), are highly correlated and values for the Soxhlet procedure are slightly lower. No significant (P<.05) differences existed between the two methods. Hence, both methods can be recommended for the determination of IMF in pork. The Soxhlet method, however, may be more indicative of marbling than the TL procedure.
