Influence of shrimp status on near infrared spectral pls model
The influence of near infrared spectral PLS model on different shrimps was analyzed.The near infrared spectral (NIS) curve of whole shrimp and minced shrimp was collected by near infrared spectroscopy analyzer (DA7200).The Unscrambler 10.3 software was used to choose the best preprocessing method and the optimal band to establish TVB-N and TBC models by partial least square regression (PLSR),and validate model.The results showed that the correlation coefficient (rc),the correction of decision (Rc2),the correlation coefficients of cross-validation (rv),the correction of decision of Cross-Validation (Rc2) of minced shrimp models were higher than those of whole shrimp models in calibration set.The root mean square error correction (RMSEC),standard error of calibration (SEC),root mean standard error of cross-validation (RMSECV),standard error of cross-validation (SECV) of minced shrimp models were not higher than those of whole shrimp models in calibration set.The correlation coefficients,the root mean square errors of prediction (RMSEP) and standard error prediction (SEP) of different models showed that the results of minced shrimp models were better than whole shrimp models in prediction set.And the minced shrimp models were better predict TVB-N and TBC in Penaeus vannamei Boone than whole shrimp model.In conclusion,minced shrimp NIR curve was better in prediction than the whole shrimps.
