Abstract
In the present paper, the moisture and oil content in gross cottonseed analyzed by near infrared reflectance spectroscopy (NIRS) technique was studied. Including the basic theory of NIRS and advantage of open detecting mode. The calibrations of the moisture and oil content in gross cottonseed were performed. The precision and accuracy of the moisture and oil content were clarified by random sampling. The correlation coefficient is high: 0.965 for moisture and 0.953 for oil. The calibration errors (SECV) for the moisture and oil content in gross cottonseed are 0.226 and 0.391 respectively. The result of NIRS prediction has been proved that the NIRS method can replace the normal analysis method completely. Further studies on the calibration of oil content in nucleus and rate of nucleus in gross cottonseed were carried out with part of samples. It has been proved that NIRS method can be applied to detect the oil content in nucleus and rate of nucleus in gross cottonseed.
