Embodiment 1
[0059] Embodiment 1 provides a method for improving the performance of myofibrillar protein, comprising the following steps:
[0060] Step 1. Remove the fat and connective tissue from the outer loin, cut it into strips and weigh it for later use. Place the processed strips of loin in a tissue masher, add four times the volume of stiffening liquid, and homogenize and smash it. After crushing and centrifugation, the primary precipitate was obtained. Add four times the volume of stiffening fluid to the primary sediment, repeat homogenization, mashing, and centrifugation 3-4 times to obtain a sediment. Four times the volume of NaCl solution was added to the precipitate, and after homogenizing and stirring, filtered through four layers of gauze to obtain a filtrate. Using HCl solution, the pH of the filtrate was adjusted to 6.20-6.25. After centrifugation again, a precipitate was obtained. is MP; wherein, the precipitate is MP, that is, the myofibrillar protein paste is obtained; ...
