Abstract:

In this study, a rapid determination method of chloramphenicol residue in milk was developed using near infrared NIR) transmission spectrophotometry and partial least squares (PLS). The correlation coefficient between true and predicted alues of chloramphenicol residue is 0.9893. The average recovery of prediction sets is 99.77%. This method can be used for the apid determination of chloramphenicol residue in milk.

Key words: near-infrared, ransmission spectrophotometry, chloramphenicol residue, milk, quantitative analysis
