Determinación del contenido de grasa y humedad en los piensos

Application Background

Fat content is an important nutritional and quality control parameter during feed production. The energy of fat is high, Increasing the fat content in the feed can improve the energy level and save protein. Sin embargo, if the fat content in the feed is too high, after long-term intake, the animal’s liver will accumulate too much fat, resulting in fatty liver disease which will affect the growth of the animal, and even causing death in severe cases. By contrary, if the fat content of the feed is too low, the energy in the feed is insufficient, and the amount of essential fatty acids provided by the fat cannot meet the growth needs of the animals.

Moisture content is an important parameter for product quality as well. If the moisture content is too high or too low, it will affect the feed quality and can complicate or even make further processing impossible. The most suitable moisture content (usually less than 10%) prevents feed spoilage and extends expiration date. Por lo tanto, we need a fast and reliable measurement of fat and moisture content to optimize feed production processes. Low-field NMR method can quickly and accurately measure the fat and moisture content of feed. Low field NMR analyzer can work at the site of factory, to provide a strong guarantee for product process optimization and quality control.

Application Principles

La intensidad de la señal de RMN es proporcional al contenido de protones de hidrógeno en la alimentación.. Podemos establecer una curva de calibración entre el contenido de grasa o agua y la intensidad de la señal de RMN.. La velocidad de relajación de la señal de RMN está relacionada con el estado de los protones de hidrógeno.. en el feed, El agua está fuertemente unida a la matriz sólida., mientras que la grasa es gratis. La señal de agua o grasa se puede distinguir según la diferencia en la velocidad de relajación.. Para realizar la detección rápida del contenido de grasa y el contenido de agua..
