After optimizing the experimental conditions, the acid hydrolysis method was compared with the Gothic-Luozi method. Both methods can completely extract the fat in this sample, and the precision meets the requirements. Gothic-Luozi method is more time-saving and convenient. When the sample contains impurities such as pigments, it is measured by the Gothic-Luomethod method. Pigments and other impurities remain in the lower layer of the solution and do not interfere with the measurement. When the acid hydrolysis method is used to measure impurities in the sample, it is also extracted into the organic solvent. The measured fat is crude fat, so the measurement result may be higher than the Gothic-Luozi method. The results of the fat analyzer are even more advantageous and accurate.
In summary, comparing three methods for determining fat in nutritious foods, such as fat analyzers, it was concluded that the improved acid hydrolysis method and Gothic-Luozi method can satisfy the measurement requirements, and Gothic-Luozi method is even more satisfactory. Accurate and convenient, it can adapt to the determination of fat in nutritious foods.
