Were cultured large yellow croaker, shrimp, mussels of the dry goods and fresh produce as experimental materials. Using traditional analytical methods and equipment to do the same detection method of the determination of nutrients and to study their differences. Related to protein content, fat content, moisture content determination of the plot, the traditional quantitative methods were used Kjeldahl method, atmospheric pressure drying method and the Soxhlet extraction method, and the experiment for protein, moisture and fat content were measured using automatic Kay Miriam's fixed nitrogen, halogen moisture and fat analyzer instrument. Experiments show that: instrumental analysis can replace the traditional methods of analysis. There is little difference between the two. General Instrument measured the results of its relatively smaller average deviation. 1绪 论 1
