Rapid Determination of Moisture and Protein contents in Silver Carp Surimi by Fourier Transform Near-Infrared (FT-NIR) Spectrometry

Moisture and protein contents in silver carp surimi were determined by Fourier transform near-infrared (FT-NIR) spectrometry in this study. Prediction error of calibration set (SEC) and validation set (SEP), correlation coefficient of calibration set (Rc) and validation set (Rv) were used to evaluate the quality of the models. The result showed that for moisture, the best calibration was developed using partial least square (PLS) with pretreatment-Normalization to Unit Length (NLE). The best calibration model of protein in surimi was also developed using PLS. The NIR, but with pretreatment- Normalization by Closure (NCL). The study demonstrated that NIR spectroscopy technology could be successfully applied as a rapid method to determine moisture and protein contents in surimi processing industry.
