Sea Buckthorn Extract Powder

Sea Buckthorn Extract Powder: A Top-Quality Bioactive Ingredient for Skin and Immune Health

Our sea buckthorn extract powder is derived from the brightly colored sea buckthorn berries, rich in sea buckthorn flavonoids, vitamin C, and other substances. Shaanxi Hongda utilizes supercritical carbon dioxide extraction technology to produce a fine powder. This method maximizes the retention of flavonoids and superoxide dismutase (SOD) content in sea buckthorn, maintaining it at 10% to 30% or higher. We not only provide raw materials but also complete solutions to help your brand enter the "oral aesthetics" and "digestive health" industries.

Shaanxi Hongda's natural sea buckthorn berry extract powder is rich in flavonoids and vitamin C, with total flavonoids greater than 10% (UV) / isorhamnetin greater than 1% (HPLC), and retains over 70% of natural vitamin C. Our sea buckthorn fruit powder, tested in the laboratory, is the purest extract currently available on the market, making it an ideal choice whether you are producing immune-boosting nutritional supplements or anti-aging beauty products.

Production Process of Seabuckthorn Extract:

1. Rapid Freezing and Cell Wall Breaking of Wild Seabuckthorn Fruit in High-Altitude Areas followed by Multi-Stage Air Classification: Wild, high-latitude seabuckthorn fruit is strictly selected and rapidly frozen at -18℃ to physically break down the cell walls. A multi-stage air classification system removes 100% of residual branches, shriveled fruit, and exogenous impurities.

2. Low-Temperature Ultrasonic Countercurrent Microwave-Assisted Aqueous Phase Extraction: The broken-down fruit pulp is fed into a multi-stage continuous countercurrent extraction line. The water temperature is controlled below 45℃. The physical cavitation effect of microwaves and ultrasound instantly releases flavonoids and polyphenols from the cells, completely eliminating the introduction of toxic solvents.

3. High-Speed ​​Disc Centrifuge for One-Phase Multi-Stage Oil-Water Separation: The extract is physically graded in a high-speed continuous disc centrifuge at 12,000 rpm, precisely separating the high-value seabuckthorn crude oil (sold separately as essential oil), leaving a clear liquid rich in water-soluble flavonoids and trace amounts of emulsified unsaturated fatty acids.

4. Online Nanoscale High-Pressure Emulsification and Homogenization of Natural Food-Grade Wall Material: Non-GMO gum arabic or sodium octenyl succinate starch is precisely proportioned online in the clarified liquid as a natural protective shell (wall material). A three-plunger high-pressure homogenizer (pressure up to 60 MPa) shears and reverse-encapsulates trace amounts of fatty acids into nanoscale microcapsules.

5. Multi-Stage Low-Vacuum Mild Temperature-Controlled Falling Film Concentration: The homogenized emulsion enters a sealed double-effect low-vacuum falling film evaporator, rapidly concentrating the material to a Baume degree of 22-25 at an extremely low boiling point of 42℃, fundamentally locking in heat-sensitive active monomers such as isorhamnetin to prevent thermal denaturation.

6. Co-current Low-Media Inlet Air Temperature Atomization Spray Drying: The concentrated paste is atomized into a drying tower via a high-speed centrifugal atomizer. The inlet air temperature is strictly controlled to not exceed 140℃, and the outlet air temperature not exceed 75℃, instantly drying and shaping the microcapsule surface to form microparticles with a highly hydrophilic protective shell.

7. Large-capacity fully automatic three-dimensional vibrating sieving and magnetic capture: The dry powder undergoes physical granulation through an 80-mesh stainless steel fully enclosed vibrating screen, while simultaneously passing through a 12,000 Gauss rare-earth strong magnetic removal device to ensure that there are absolutely no large particle clumps or trace mechanical metal foreign objects in the bulk shipment.

8. Aseptic nitrogen-filled packaging with controlled ambient humidity below 35 degrees Celsius: In a Class 100,000 cleanroom with relative humidity strictly controlled below 35%, a fully automatic filling machine seals the dry powder into double-layer aluminum foil bags and fills them with high-purity nitrogen to replace oxygen, completely locking in the oxidation of internal lipids for shelf life.

FAQ

Q: What's the difference between sea buckthorn extract and sea buckthorn fruit powder?

A: Sea buckthorn fruit powder is usually simply dried and ground, resulting in a lower concentration of active ingredients. Hongda provides extracts, which utilize supercritical fluid extraction technology to selectively enrich flavonoids and fatty acids. Their bioactivity and stability are far superior to ordinary fruit powder, and they require significantly less addition to the formulation.

Q: How do you guarantee no solvent residue during the extraction process?

A: We use supercritical CO2 extraction. This is a physical extraction process where the CO2 automatically vaporizes and leaves after circulation, involving no organic solvents (such as hexane or methanol), fully complying with "Clean Label" requirements.

Q: How does your Sea Buckthorn Extract Powder compare to vitamin C?
A: It has more bioavailable and varied antioxidants than manufactured ones.

Q: Is there a water-soluble version for drinks?
A: Yes! Ask our team about solubility-optimized formats.

Q: Are samples available?
A: Qualified purchasers get free samples.

Q: How do you sustain?
A: Zero-waste processing and carbon-neutral packaging.
