3 Terms and Definitions
The terms and definitions defined in GB/T 40467 and NY/T 3512 and the following terms and definitions apply to this document.
3.1
sample set sampleset
It is representative to cover the minimum to maximum range of moisture, protein, and fat content, to meet the sample size requirements of the relevant process, and the same
A collection of livestock and poultry meat samples of the same sample form.
4 Principles
Utilize the combined frequency or double vibration of chemical bonds such as hydrogen-containing groups XH (X=C, N, O) in livestock and poultry meat under the wavelength of 780nm~2526nm
The absorption spectrum generated by the frequency was used to establish the quantitative analysis and calibration model of water, protein and fat content by the multivariate calibration method, and then the detection
The near-infrared spectrum of the sample is imported into the calibration model to realize the simultaneous and rapid detection of the moisture, protein and fat content in livestock and poultry meat.
5 Instruments and equipment
Instruments and equipment should comply with the provisions of GB/T 40467.
6 Specimen Preparation
Select calibration samples and test samples according to the method specified in GB/T 9695.19, avoiding the visible adipose tissue and fascia on the surface of livestock and poultry meat.
