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 an algal polysaccharide extract as well as application and a preparation method thereof. The algal polysaccharide extract is extracted from a composition of green algae and brown algae. In addition, the invention also discloses a preparation method of the algal polysaccharide extract, which comprises the following steps of a, weighing green algae and brown algae according to the dry weight ratio, mixing, crushing, sieving the crushed material, then carrying out ultrasonic extraction by adopting a calcium chloride aqueous solution, filtering the extracted solution, and collecting the filtrate, b, adding polyamide and resin into the filtrate collected in the step a, stirring for a period of time, filtering, and collecting the filtrate, and c, concentrating the filtrate collected in the step b to 1 / 5-1 / 8 of the original volume, filtering, adding ethanol into the filtrate, standing for 4-6 hours at 4-8 DEG C, collecting the solid, and drying to obtain the product. The algal polysaccharide extract disclosed by the invention has a remarkable synergistic moisturizing effect, can also effectively promote the repair of skin barriers, and can be used for developing 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...
