Milk powder fat content and moisture content detection - low field nuclear magnetic resonance spectrometer
There is a great demand for milk powder in the market, and factories produce milk powder products with different fat contents according to customer needs. It is very necessary to measure the fat content of these milk powder products. The moisture content of milk powder products also has requirements, and the water content is generally less than4%Excessive moisture can make the product prone to spoilage.
At present, the oil content in milk powder can be measured by solvent extraction, which is a time-consuming method that requires chemical reagents and professional operators. Moisture testing can be measured by drying method, and the testing process is relatively slow and requires operators.
Milk powder fat content and moisture content detection - basic parameters of low field nuclear magnetic resonance instrument:
1. Magnet type: permanent magnet;
2. Magnetic field strength: 0.5 ± 0.08T;
3. Probe coil diameter: 25mm;
The testing principle of low field nuclear magnetic resonance method is shown in the following figure:
By calibrating the curve, the fat and moisture content in milk powder and milk powder products can be quickly detected.
Compared to traditional technology, (Low field nuclear magnetic resonance spectrometer for detecting fat and moisture content in milk powderMeasuring the fat and moisture content in milk powder products has many advantages. The low field nuclear magnetic resonance method has fast testing speed and simple operation, which can collect and measure more samples in the same time, improve detection efficiency, achieve process detection, and better evaluate quality control.
