Abstract:

In order to improve the utilization value and biological activity of cartilage protein, Polyodon spathula cartilage was used as the material to extract cartilage protein by microwave-alkali extraction method. The optimal enzymatic hydrolysis conditions of cartilage protein were explored by single factor and orthogonal experiments to be enzymatic hydrolysis temperature of 50 ℃, cartilage protein concentration of 1%, hydrolysis pH of 7.5, alkaline protease amount of 9000 U, and hydrolysis time of 5 h. The yield of amino nitrogen was 21.89% under the optimal conditions.

Key words: Polyodon spathula, cartilage protein, enzymatic hydrolysis
