Embodiment 1

[0035] Embodiment 1 provides a kind of preparation method of seaweed polysaccharide extract, in the present embodiment, the weight ratio of Ulva, Fucus and other brown algae is 1:16.7:2.3, specifically comprises the following steps:

[0036] (1) Take 10g of dried Ulva, 167g of Fucus, 11g of seaweed, 6g each of Hijiki and Undaria pinnatae, mix them and make powder, pass through a 10-mesh sieve, and use a mass of 2.0kg for the algae powder obtained by sieving The calcium chloride aqueous solution with a percentage of 1% was ultrasonically extracted twice, each time for 20 minutes (the power of ultrasonic extraction was 400W). The two extracts were combined and filtered with a 5 μm polypropylene membrane to obtain 2.9 kg of filtrate;

[0037] (2) Add 50g polyamide and 50g snake cage resin to the filtrate of step (1), after stirring at room temperature for 1 hour, filter with a 0.8 μm polypropylene membrane to obtain 2.6kg of filtrate;

[0038] (3) Concentrate the filtrate of ste...

Embodiment 2

[0040] Embodiment 2 provides a kind of preparation method of seaweed polysaccharide extract, in the present embodiment, the weight ratio of Ulva, Fucus and other brown algae is 1:80:15, specifically comprises the following steps:

[0041] (1) Take 2g of dried Ulva, 160g of Fucus, 10g of seaweed, 10g of Hijiki, and 10g of Undaria pinnatifida, mix them and make powder, pass through a 10-mesh sieve, and use a mass percentage of 2kg for the algae body powder obtained by sieving The 1% calcium chloride aqueous solution is ultrasonically extracted twice, each time for 20 minutes (the power of ultrasonic extraction is 400W). Combine the two extracts and filter with a 5 μm polypropylene membrane to obtain 3.0 kg of filtrate;

[0042] (2) Add 60g polyamide and 60g snake cage resin to the filtrate of step (1), after stirring at room temperature for 1 hour, filter with a 0.8 μm polypropylene membrane to obtain 2.5kg of filtrate;

[0043] (3) Concentrate the filtrate of step (2) to about...

Abstract

The invention discloses a seaweed polysaccharide extract, application and preparation method thereof. Wherein, the seaweed polysaccharide extract is extracted from the composition of green algae and brown algae. In addition, the present invention also discloses the preparation method of the above-mentioned seaweed polysaccharide extract, which includes the following steps: Step a: Mix green algae and brown algae according to the dry weight ratio, mix and pulverize, sieve the pulverized product, and then use chlorination Ultrasonic extraction of the calcium aqueous solution, filtering the extracted solution, and collecting the filtrate; step b: adding polyamide and resin to the filtrate collected in step a, stirring for a period of time, filtering, and collecting the filtrate; step c: concentrating the filtrate collected in step b to 1 / 5-1 / 8 of the original volume, filter, then add ethanol to the filtrate, let it stand at 4-8°C for 4-6 hours, collect the solid, and dry it. The seaweed polysaccharide extract in this case has a significant synergistic moisturizing effect, and can also effectively promote the repair of the skin barrier, and can be used in the development of moisturizing and repairing products.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction, and in particular relates to a seaweed extract and its preparation method and application. Background technique [0002] With the growth of age and the deterioration of the external environment, the moisturizing function of the skin decreases, which in turn leads to the dehydration and hardening of collagen, causing a series of problems such as chapped skin, wrinkling, and damaged skin barrier. At present, hyaluronic acid is recognized as an ideal natural moisturizing factor, but hyaluronic acid comes from animal tissue or genetically engineered fermentation, which is different from pure natural plant sources, and its function is relatively single, mainly moisturizing and lubricating, and cannot repair damaged skin. damaged skin barrier. The moisturizing effect of plant-derived moisturizing factors is generally not outstanding enough. [0003] Based on this, it is expected to...
