[0002] Fucoxanthin (fucoxanthin) is a carotenoid substance, mostly distributed in algae, marine phytoplankton, and aquatic shellfish. Fucoxanthin has a long conjugated double bond and contains allene and alkylene oxide. This special structure makes it have a variety of biological activities, including anti-tumor, weight loss, blood lipid lowering, anti-oxidatio

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.

Abstract

The invention discloses a preparation method of a fucoxanthin microcapsule, which belongs to the technical field of food processing. The preparation method comprises the following steps: (1) uniformly mixing palm stearin and fucoxanthin to be used as a core material, and ultrasonically dispersing the core material in a gelatin solution to form uniform emulsion; (2) adding an Arabic gum solution containing a surfactant into the emulsion of the step (1), stirring for 5 to 15 min at constant temperature, adjusting PH to be 3.8 to 4.2 by utilizing acetic acid, and carrying out complex coacervation; (3) lowering the temperature of a system of step (2) to be lower than 10 DEG C, adding a tannic acid solution, and curing microcapsules; and (4) after the microcapsules are precipitated, adding deionized water to wash the microcapsules, repeating for multiple times, and freeze drying to obtain microcapsule powder. The fucoxanthin microcapsule prepared by the invention is uniform in particle size, stable in structure, and unlikely to have the situation such as breaking and leakage of core materials, so that the storage and application of the fucoxanthin can be facilitated.

Description

technical field [0001] A method for manufacturing fucoxanthin microcapsules belongs to the technical field of food processing. Background technique [0002] Fucoxanthin (fucoxanthin) is a carotenoid substance, which is mostly distributed in algae, marine phytoplankton, and aquatic shellfish. Fucoxanthin has a long conjugated double bond and contains allene and alkylene oxide. This special structure makes it have a variety of biological activities, including anti-tumor, weight loss, blood lipid lowering, anti-oxidation, and blood sugar regulation. However, due to its highly unsaturated structure, fucoxanthin is for Factors such as light, oxygen, temperature, enzymes, and PH value are unstable, prone to oxidation and isomerization, and are difficult to store for a long time. In addition, the low water solubility of fucoxanthin limits its application in water-containing foods. [0003] Palm stearin is the solid part separated from palm oil after freezing and crystallization. I...
