Sea buckthorn (Hippophae rhamnoides) is known as the "King of Vitamin C." Its juice powder, rich in total flavonoids, vitamin C, organic acids, and rare palmitoleic acid, has become a popular ingredient in functional beverages, meal replacements, and beauty drinks.

6 Key Indicators of High-Quality Sea Buckthorn Juice Powder

Raw Material Traceability – "Small Production Areas" are Superior to "Bulk Commodities"
High-altitude regions such as the Qinghai Plateau, Ulagai in Inner Mongolia, and the Qilian Mountains in Gansu have long sunshine hours and large diurnal temperature differences, resulting in sea buckthorn with total flavonoid content exceeding 1.2%, on average 30% higher than those grown in plains. Suppliers should provide GPS coordinate-level origin certificates, and verification of wild or organic certification is required.

Ingredient Purity – The Ingredient List Should "Only Subtract"
A truly "sea buckthorn juice powder" should only have one ingredient listed: Sea buckthorn juice powder. If "maltodextrin, sucrose, or citric acid" are present, it can be considered a filler-type product, and the active ingredient content must be discounted accordingly.

Processing Details – Low-Temperature Belt Drying for Freshness Preservation
Vacuum low-temperature belt drying (≤45 ℃) can maintain a vitamin C retention rate of over 90%, resulting in uniform particles and good solubility; while traditional spray drying, with an inlet air temperature as high as 180 ℃, can lead to a vitamin C loss of up to 40%. After sampling, perform a "cold water rapid dissolution test": 5 g of powder + 200 mL of 25 ℃ water, stirring for 10 seconds should result in complete dispersion with no visible fruit residue.

Active Ingredients – Include "Flavonoids" in the Contract
Using total flavonoids ≥1.0% and vitamin C ≥600 mg/100 g as baseline values, require suppliers to provide third-party HPLC chromatograms with the shipment; if used for "antioxidant" claims, it is recommended to also test the ORAC value, with ≥5000 μmol TE/g making differentiation easier. Safety Indicators – Zero Tolerance for Heavy Metals
Lead ≤ 0.3 ppm, Cadmium ≤ 0.2 ppm, Total Arsenic ≤ 0.1 ppm, and mycotoxins (patulin) must not be detected, meeting EU EC 1881/2006 standards.

Certification Endorsement – ​​The Most Reassuring "Dual Standard" System
Companies that have simultaneously obtained ISO 22000 and EU/USDA organic certifications offer greater assurance of batch consistency, significantly reducing customer on-site audit costs.

Three Multi-Source Consumption Options for Sea Buckthorn Juice Powder

Functional Ready-to-Drink – "Light Nourishment" Meal Replacement
Formula: 8% sea buckthorn juice powder + 3% inulin + 2% erythritol + 1% coconut powder MCT.  Each serving is 30g, simply mix with hot water. The combination of Vitamin C and medium-chain fatty acids meets the dual needs of antioxidant and ketogenic diets for breakfast meal replacement.

Probiotic Carrier – "Sea Buckthorn Yogurt Powder"
Utilizing the natural organic acids of sea buckthorn (pH 3.2–3.5) to inhibit miscellaneous bacteria, combined with freeze-dried lactic acid bacteria powder to create ready-to-drink granules. It has a shelf life of up to 18 months and requires no refrigeration. Each sachet contains 2g, with live bacteria ≥10^11 CFU, suitable for travel.

Beauty Solid Beverage – "Oral Skin Brightening"
Sea buckthorn juice powder is dry-mixed with collagen peptides and rice ceramides in a 5:3:1 ratio, made into stick packs. One pack daily for 8 consecutive weeks can increase skin moisture by 15% (internal clinical data). High content of Vitamin C promotes collagen synthesis, and palmitoleic acid (Omega-7) repairs mucous membranes, providing both internal and external benefits.
