Study of properties of raw meat from unconventional animals with anomalous nature of autolysis

Rational use of meat with deviations in the process of autolysis becomes very important, because the number of slaughter animals that have deteriorated organoleptic indices and functional-technological properties during maturing of muscle tissue has significantly increased. Such raw materials are divided into meat with PSE (pale, soft - flabby or soft, exudative - watery, pH less than 5.2) and DFD (dark - firm, firm - dense, dry - dry, pH more than 6.4) - properties. Meat with signs of PSE and DFD reaches 40-50%, so meat industry specialists are tasked to develop affordable methods of meat identification for PSE, DFD and NOR groups and on their basis technological solutions for improving the quality of products. The purpose of the research was to study the change in functional and technological properties of non-traditional types of meat with an abnormal character of autolysis. The study of pH showed an increase in the index to 7.1 in pheasant meat. For the rest of the game the hydrogen index was at the level of 6.75-6.8, which is a deviation from the norm. Physicochemical studies of venison muscle tissue showed that the pH was 6.2. This indicator is considered the norm for ripe meat. Of practical interest is the study of water binding capacity. From meat with a small water-binding capacity, it is difficult to produce high-quality products, since during processing, the loss of moisture and, accordingly, the soluble substances in it is great. Studies have shown that the percentage of bound moisture to the sample is small, and its maximum value is 19.3% in male mallard meat. If we take in comparison only game meat, then the difference in the rates is 1.6-4.3% and we can speak about small losses of moisture. In cloven-hoofed animals, the difference in the index was only 0.4%.
