What is PD CEN/TR 17474 about?
PD CEN/TR 17474 defines the repeatability and the reproducibility of a method using near-infrared spectroscopy in whole kernels for the determination of moisture and protein on wheat and barley. The performance of the method (accuracy) is found in EN 15948.
The values derived from the report are applicable to the following concentration ranges:
For wheat:
- Moisture contents range from 9,5 % – 15,7 %
- Protein contents range from 10,0 % DM to 18,6 % DM
For barley:
- Moisture contents range from 10,6 % – 15,9 %
- Protein contents range from 9,2 % DM – 15,4 % DM
Who is PD CEN/TR 17474 for?
PD CEN/TR 17474 on determination of moisture and protein content in cereals is relevant to:
- Food technologists
- Food testing laboratories
- Agriculture service laboratories
- Grain networks
Why should you use PD CEN/TR 17474?
Transferability is the ability to get the same analytical result on different instruments with the same sample. With regards to grain analysis, a large number of instruments and wide variations in temperature and humidity can significantly affect these results. Thus, PD CEN/TR 17474 aims to standardise the determination of moisture and protein content in whole kernels of barley and wheat, which is done using a near infrared spectrometer.
As a result, you can ensure the essential characteristics are retained even with the use of different instruments and calibration models. For prediction models, the standard deviations of these differences in instrument are key measures, which are covered in PD CEN/TR 17474.
With PD CEN/TR 17474, you can maintain accuracy and precision in methods for determining the moisture content and protein in whole kernel for grain analysis.
