Embodiment 1
[0017] A processing method for maintaining the brittleness of the petiole of S. sylvestris includes the following:
[0018] (1) Separate the collected leaves, petioles and roots of Saussurea spp., and treat the leaves and roots according to conventional methods. After the petioles are cleaned and cut into sections, they are refrigerated at 6°C for 18 hours;
[0019] (2) Pre-cook the refrigerated petiole segments in a citric acid solution with a mass concentration of 0.25% for 5 minutes, and drain the water for use;
[0020] (3) Degreasing and hydrolyzing the corn gluten meal, separating the hydrolysate from solid and liquid to obtain a compound amino acid solution, and soaking the spare petiole section for 1.5 hours at a temperature of 48°C and a pH of 5.4;
[0021] The degreasing method of the corn gluten meal is to mix the corn gluten meal with an organic carboxylic acid with a mass concentration of 2.7 mol / L and a carbon number of 6 in a weight ratio of 4:6, and then keep it at a te...
Embodiment 2
[0026] A processing method for maintaining the brittleness of the petiole of S. sylvestris includes the following:
[0027] (1) Separate the collected leaves, petioles and roots of Saussurea vulgaris, treat the leaves and roots according to conventional methods, clean the petioles, cut into sections, and refrigerate them at 8°C for 12 hours;
[0028] (2) Pre-cook the refrigerated petiole segments in a citric acid solution with a mass concentration of 0.3% for 6 minutes, and drain the water for later use;
[0029] (3) Degreasing and hydrolyzing the corn gluten meal, separating the hydrolyzed product from solid and liquid to obtain a compound amino acid solution, and soaking the above spare petiole segment at a temperature of 50°C and a pH of 5.5 for 2 hours;
[0030] The degreasing method of the corn gluten meal is to mix the corn gluten meal with an organic carboxylic acid with a mass concentration of 2.2 mol / L and a carbon number of 5 in a weight ratio of 4:6, and then keep it at a te...
Embodiment 3
[0034] A processing method for maintaining the brittleness of the petiole of S. sylvestris includes the following:
[0035] (1) Separate the collected leaves, petioles and roots of Saussurea vulgaris, treat the leaves and roots according to conventional methods, clean the petioles, cut into sections, and refrigerate them at 5°C for 48 hours;
[0036] (2) Pre-cook the refrigerated petiole segments in a citric acid solution with a mass concentration of 0.2% for 4 minutes, and drain the water for use;
[0037] (3) Degreasing and hydrolyzing the corn gluten meal, separating the hydrolysate from solid and liquid to obtain a compound amino acid solution, and soaking the above-mentioned spare petiole segment at a temperature of 45°C and a pH of 5.2 for 1 hour;
[0038] The degreasing method of the corn gluten meal is to mix the corn gluten meal with an organic carboxylic acid with a mass concentration of 3.2 mol / L and a carbon number of 8 in a weight ratio of 4:7, and then keep it at a temper...
