Pork fat can be generally divided into subcutaneous fat and muscle fat. Subcutaneous fat mainly refers to the fat tissue between the skin and muscle tissue, commonly known as wolfberry, subcutaneous fat often because of its different parts and different names, such as the back of the called back 膘Wait. Muscle fat includes intermuscular fat and intramuscular fat, wherein intermuscular fat refers to fat that exists between striated muscles (muscles), and intramuscular fat refers to fat that exists between muscle bundles in striated muscle and in muscle cells. , Such as epimyocardial, perimysial and intramuscular fat. The determination of intramuscular fat in pig muscle is a core indicator for the evaluation of pork quality, and its accuracy is of great significance in breeder breeding and commercial production. The result of measuring the fat content by the fat analyzer is very accurate. Therefore, it can provide effective help for the determination of pork fat content.

There is a high correlation between the three methods of fresh sample extraction, Soxhlet extraction and near-infrared spectroscopy. Further analysis showed that the data obtained from the two methods of fresh sample extraction and near infrared spectroscopy had no significant difference, while the data obtained from the two methods of fresh sample extraction and Soxhlet extraction showed significant differences; near infrared Spectral method and Soxhlet extraction method are significantly different. The reason may be related to the different pretreatment methods (fresh and dry samples) and reagents used in the extraction.

Marble scores are only used as an aid. The near-infrared spectroscopy has the characteristics of rapidness, accuracy, and convenience. It can be used as a new method for detecting intramuscular fat in pig muscles. Its disadvantage is that the instrument is expensive. The regression analysis results showed that the measured data of the near-infrared spectroscopy can also be consistent with the fresh sample extraction method according to the estimation of the regression equation. Near-infrared spectroscopy for the determination of intramuscular fat of pig muscles is a reliable and rapid detection method. It provides a new way for the rapid detection of intramuscular fat. The fat analyzer has established a certain improvement for the determination of intramuscular fat in our country and the revision of standards. basis.
