The application discloses a PSE meat protein efficient extraction method based on alkaline pH regulation, and belongs to the technical field of meat protein extraction. The steps are as follows: after PSE meat is uniformly homogenized, pre-cooled deionized water is added at 1:9 (w / v), the pH is adjusted to 11.5-13.0, stirring extraction is carried out for 5 min, and the supernatant is collected by centrifugation; the pH of the supernatant is adjusted back to 5.5, and after standing and precipitating, centrifugation is carried out, and the precipitate is collected; the precipitate is freeze-dried, and PSE meat myofibrillar protein is obtained. The application aims at the problems of PSE meat protein denaturation and functional property deterioration, realizes efficient dissolution of protein through alkaline pH regulation, has high protein purity and retains complete salt-soluble protein, and provides a simple and efficient solution for high-value utilization of PSE meat.
