Embodiment 1
[0028] The preparation method of protein-chitosan complex coagulation food microcapsule system in the present embodiment comprises the following steps:
[0029] 1. Firstly, prepare soybean protein isolate / sodium alginate aqueous solution: mix 2.1818g soybean protein isolate and 0.2182g sodium alginate and dissolve them in deionized water, keeping the mass ratio of soybean protein isolate and sodium alginate at 100:10. 10% (w / v) sodium hydroxide solution was used to adjust the pH to 8.0, stirred with a magnetic stirrer until completely dissolved, and the volume was adjusted to 100 mL to obtain a 2.4% (w / v) soybean protein isolate / sodium alginate aqueous solution.
[0030] 2. Dilute 1% (w / v) chitosan solution to 0.6% (w / v) with 1% (w / v) acetic acid solution, and then mix with the above 2.4% (w / v) soybean protein isolate / Sodium alginate aqueous solution is mixed in equal volumes, at this time, the mass ratio of soybean protein isolate to chitosan is 3.64:1, and the total solids ...
Embodiment 2
[0034] The preparation method of protein-chitosan complex coagulation food microcapsule system in the present embodiment comprises the following steps:
[0035] 1. First, prepare a soybean protein isolate / pectin solution: mix and dissolve 2.3857g soybean protein isolate and 0.0143g pectin into deionized water, keeping the mass ratio of soybean protein isolate and pectin at 100:0.6. 10% (w / v) sodium hydroxide solution was used to adjust the pH value to 7.0, stirred with a magnetic stirrer until it was completely dissolved, and the volume was adjusted to 100 mL to obtain a 2.4% (w / v) soybean protein isolate / pectin aqueous solution.
[0036] 2. Dilute 1% (w / v) chitosan solution to 0.8% (w / v) with 1% (w / v) acetic acid solution, and then mix with the above 2.4% (w / v) soybean protein isolate / The pectin solution was mixed in equal volumes. At this time, the mass ratio of soybean protein isolate to chitosan sugar was 2.98:1, and the total solids concentration of the solution was 1.6%...
Embodiment 3
[0040] The preparation method of protein-chitosan complex coagulation food microcapsule system in the present embodiment comprises the following steps:
[0041] 1. First prepare pea protein isolate / sodium alginate solution: mix and dissolve 0.0857g pea protein isolate and 0.0043g sodium alginate into deionized water, keeping the mass ratio of pea protein isolate and sodium alginate at 100:5.02. Adjust the pH value to 7.0 with 10% (w / v) sodium hydroxide solution, stir with a magnetic stirrer until completely dissolved, and dilute to 100 mL to obtain 0.09% (w / v) pea protein isolate / sodium alginate aqueous solution.
[0042] 2. Dilute 1% (w / v) chitosan solution to 0.01% (w / v) with 1% (w / v) acetic acid solution, and then mix with the above 0.09% (w / v) pea protein isolate / The sodium alginate solution was mixed in equal volumes. At this time, the mass ratio of pea protein isolate to chitosan was 8.57:1, and the total solids concentration of the solution was 0.05% (w / v). Adjust the...
