Embodiment 1

[0031] Example 1: Preparation of Spirulina Polysaccharide Powder:

[0032] extract:

[0033] 1. Weighing: Weigh 10.00g spirulina powder into a 500ml beaker

[0034] 2. Dissolution: add deionized water to the beaker at a ratio of 1:25 (g / ml)

[0035] 3. Freezing and thawing treatment: freeze at -20°C for 4 hours and take out. Then thaw in a 37°C water bath and repeat this 3 times

[0036] 4. Ultrasound: After thawing is completed, ultrasonicate for 15min at 80Hz

[0037] 5. Extraction: After ultrasonication, the extraction was carried out at a constant temperature of 90 °C for 3 hours.

[0038] 6. Centrifugation: Centrifuge the extract at 3000r / min for 10min, take the supernatant

[0039] 7. Concentration: the extract was concentrated under reduced pressure at 70°C to obtain a concentrate

[0040] 8. Alcohol precipitation: then use 5 times the volume of the concentrated solution for alcohol precipitation with 95% ethanol overnight, centrifuge at 3000 r / min for 10 min, tak...

Embodiment 2

[0049] Example 2: Preparation of cream:

[0050] raw material:

[0051] Caprylic acid triglyceride: purchased from the Making Cosmetics website (trade name Triglyceride)

[0052] Tocopheryl acetate: purchased from the website of Making Cosmetics (trade name Vitamin E (dl-alphatocopheryl acetate)

[0053] Glyceryl stearate, polyethylene glycol-100 stearate: available from the website of Making Cosmetics (trade name BLEND)

[0054] Sodium acrylate / sodium acryloyl taurate copolymer, isohexadecane, polysorbate 80: purchased from the website of MakingCosmetics (trade name EMU)

[0057]Glycerin: purchased from the Making Cosmetics website (trade name Glycerin)

[0058] Cetearyl Alcohol: purchased from Source Leaf Bio

[0059] Sodium pyrrolidone carboxylate: purchased fr...

Embodiment 3

[0073] Example 3: Stability test, see figure 2

[0074] Centrifugation test:

[0075] Process: Put the sample into a centrifuge tube with a scale of 10ml to about 2 / 3 of the height, and pack it firmly, plug it with a lid, and then put it into an electric heating constant temperature incubator pre-adjusted to 40 °C, and keep it for 1 hour. Put the centrifuge tube into the centrifuge to keep the balance, and centrifuge at 2000r / min for 30min to observe whether there is oil-water layer and particles.

[0076] Result: No oily moisture layers, no particles.

[0077] Heat resistance test:

[0078] Process: Put the sample into a sealed centrifuge tube, set the temperature in an incubator at 40°C for 24 hours, and then return to room temperature to observe the discoloration of the liquid and the stratification of oil and water.

[0079] Result: No oily moisture layers, no particles.

[0080] Cold resistance test

[0081] Process: Put the sample into a sealed centrifuge tube, pu...

Abstract

The invention discloses a preparation method of a composition containing spirulina polysaccharide extract. The preparation method comprises the following steps of: heating and dissolving an A-phase raw material; heating and melting a B-phase raw material and adding the B-phase raw material into the A-phase raw material; stirring while adding; homogenizing; then adding a C-phase raw material in sequence in a stirring process; homogenizing and stirring to obtain the composition. The A-phase raw material comprises caprylic / capric triglyceride, CreamMaker-Blead, Gelmaker EMU and vitamin E acetate;or the A-phase raw material comprises jojoba oil, CreamMaker-Blead, avocado oil, cetostearyl alcohol, vitamin E acetate and Gelmaker EMU; the B-phase raw material comprises glycerol, sodium hyaluronate and de-ionized water; or the B-phase raw material comprises glycerol, sodium hyaluronate, sodium pyrrolidone carboxylate, 1, 3-butanediol and de-ionized water; and the C-phase raw material comprises spirulina extract, butterflybush flower extract, grape seed extract, ulmus pumila extract, asiaticoside extract, benzyl alcohol-DHA and essence. The product disclosed by the invention has relativelygood stable properties including heat resistance, cold resistance and the like, has a relatively good cleaning effect on DPPH and. OH and has relatively good moisture retention.

Description

technical field [0001] The invention relates to a preparation method of a spirulina polysaccharide extract product, in particular to a preparation method of a composition containing the spirulina polysaccharide extract. Background technique [0002] With the advancement of technology and the advent of more and more electronic products, people are also exposed to blue light environment too much. Compared with ultraviolet rays, blue light has stronger penetrating power and can reach the dermis layer of human skin, thereby causing damage to the skin. Such as oxidative stress, pigmentation, etc., in addition to causing damage to retinal cells, resulting in decreased vision or even loss. The damage caused by blue light also makes anti-blue light products more and more sought after by people. [0003] Spirulina is rich in polysaccharides, proteins, amino acids, vitamins, carotenoids, γ-linolenic acid, inorganic elements Na, K, Ca, Mg and trace elements Fe, Co, Mn, Ni, Cr, V, Zn,...
