FIELD: analytical methods in food industry.
SUBSTANCE: weighed sample is placed in nuclear-magnetic relaxation signal sensor of pulse NMR analyzer and kept to equilibrate temperature at 24°C, after which maximum amplitude characterizing water proton signal amplitude (A3) is measured and, using linear equation B=0.0824*A3-5.1799, percentage of moisture is found and then percentage of fat is determined from formula Fat=100-B.
EFFECT: enabled rapid determination of fat without use of toxic solvents.
