Abstract: A portable ncar infrared speclromclcr was applied to collect spectral inlormation in the shorl-wave infrared reyion
o1 236 samples o! Ircsh chicken to stablish a quantitalive model for predicting the cholesterol content of Ircsh chicken
breast through partial Icasl squares regression combincd with chemometrics. The results showed thal the optimal spectral
prctrcatmcnt mcthod was the combinalion of normalization and baseline correction. Model calibration was achicved by
climination of abnormal valucs performed twice. Paramcters of the optimal prediction model developed were determincd as
follows: R (correlation coc ieicnt lor calibration se)0.801 1, SEC(slandard crtor of calibration)6.6998, R,(corrclation
cocllicicnt for prediction sel)0. 8034, s=(standard crror o[ prediction) 7.529 6, MF(number o! main lactors) 4, and
Spi'src 1 12, which indicated the prediction modcl had better reliability; robustness and performance than other modcls
Key words: portable ncar infrared spectrometer(NIR); shorl-wavc NIR region; rapid nondestructive prediction; fresh
