Example Embodiment
[0015] Example 1
[0016] 1 part of a mixture of fucoxanthin and palm oil at a mass ratio of 0.01:1, add to 40 parts of fish gelatin solution with a mass fraction of 1%, 200w ultrasonic for 2min, add 39 parts of acacia and Tween 80 mixture ( Among them, the volume ratio of Tween 80 to the gum arabic solution with a mass fraction of 1% is 1:30), stirring at a constant temperature of 40°C for 5 minutes, rotating at 400rpm, adjusting the pH to 3.8 with acetic acid, cooling to below 10°C, adding tannic acid The solution (with a mass fraction of 0.05% in the total system) solidifies the microcapsules, and freeze-drying after washing to obtain a fucoxanthin microcapsule product with a particle size of 79 μm.
Example Embodiment
[0017] Example 2
[0018] 1 part of a mixture of fucoxanthin and palm oil at a mass ratio of 0.4:1, added to 24 parts of 3% fish gelatin solution, ultrasonicated at 300w for 1min, and added 20 parts of acacia and Tween 80 mixture ( Among them, the volume ratio of Tween 80 to the gum arabic solution with a mass fraction of 3% is 1:10), stirring at a constant temperature of 55°C for 15 minutes, rotating at 800rpm, adjusting the pH to 4.0 with acetic acid, cooling to below 10°C, adding tannic acid The solution (in the total system with a mass fraction of 3%) solidifies the microcapsules, and freeze-drying after washing to obtain a fucoxanthin microcapsule product with a particle size of 23μm.
Example Embodiment
[0019] Example 3
[0020] 1 part of a mixture of fucoxanthin and palm oil in a mass ratio of 0.3:1, add to 5 parts of 2% fish gelatin solution, 150w ultrasonic for 5min, add 5 parts of acacia and Tween 80 mixture ( Among them, the volume ratio of Tween 80 to the gum arabic solution with a mass fraction of 2% is 1:20), stir at a constant temperature of 35°C for 10 minutes, rotate at 1200 rpm, adjust the pH to 4.2 with acetic acid, cool to below 10°C, add tannic acid The solution (the mass fraction in the total system is 1%) solidifies the microcapsules, and freeze-drying after washing to obtain a fucoxanthin microcapsule product with a particle size of 57μm.
