Rosa Roxburghii Fruit Extract

Rosa Roxburghii Fruit Extract (also known as Cili Powder or Silk Flower Fruit Powder) is a high-nutrient plant-derived juice powder made from wild or cultivated Rosa roxburghii fruits in Guizhou, China. Processed using low-temperature juicing, concentration, and spray/freeze-drying techniques, this ingredient preserves the fruit's naturally high vitamin C, antioxidant enzymes, and polyphenols, offering a versatile solution for functional beverages, dietary supplements, nutrition powders, and cosmetic applications.

Rosa Roxburghii Juice Powder is a nutritious, natural plant powder, ranging in color from pale yellow to golden yellow, with the distinctive fruity aroma and a sweet-sour taste characteristic of Rosa Rugosa. Its fine texture makes it easily soluble, allowing for wide application in food, pharmaceutical, and other industries, injecting natural vitality and health into your products.

Rosa Rugosa (or Rose Roxburghii, as the original text specifies the botanical name Rosa roxburghii Tratt) is a unique fruit found in China's southwestern regions, and its fruit is rich in various nutritional components.

3 Key Icon Highlights:

Positioning Example: "Natural Vitamin C powerhouse with antioxidant support for functional food and supplement formulations."

1. Raw Material Selection & Preparation

Fully ripe wild or cultivated fruits are harvested, cleaned, and sorted.

2. Juicing & Enzyme Treatment

Fruits crushed; enzymatic treatment enhances juice yield and preserves nutrient content.

3. Filtration & Deaeration

Removes solids, prevents oxidation during processing.

4. Concentration

Vacuum evaporation concentrates juice to ~40–65% soluble solids while retaining nutrients.

5. Drying

Spray or freeze-drying reduces moisture to ≤5% to produce a fine, stable powder.

6. Milling & Packaging

• Powder milled to 80–120 mesh for optimal solubility and uniformity.
• Packed in moisture-resistant, light-protected containers.

7. Quality Assurance

Full COA, ISO/HACCP/KOSHER/HALAL certifications, batch-controlled production for consistent color, flavor, and nutrient retention.

Rosa Roxburghii Fruit Extract fits cleanly across multiple high-growth product categories. Its water-solubility, mild flavor profile, and multi-mechanism antioxidant activity make it one of the most versatile botanical ingredients available to formulators today.

Note: Both belong to the Rosa genus, but species, nutrient profile, and functional positioning are different. They are not interchangeable in formulations.

Not all Rosa Roxburghii extracts on the market are equivalent. Here is how our product compares to common alternatives across the criteria that matter most for B2B buyers:

The competitive advantage here is clear: our extract allows you to make multi-mechanism antioxidant claims - natural vitamin C, SOD activity, and polyphenol content - from a single, traceable botanical ingredient. That is a formulation and marketing advantage that synthetic ascorbic acid simply cannot replicate.

Q1: What is the difference between Rosa Roxburghii Fruit Extract and a standard vitamin C supplement ingredient?

Standard vitamin C ingredients - including most "natural" vitamin C on the market - deliver ascorbic acid as the sole active compound. Rosa Roxburghii Fruit Extract delivers vitamin C within a whole-fruit bioactive matrix that includes native SOD enzyme activity, polyphenols, flavonoids, and triterpenoids. This multi-compound profile enables broader label claims and supports more comprehensive antioxidant positioning. The two ingredients are not interchangeable from a formulation or marketing standpoint.

Q2: How is SOD activity measured, and is the declared activity stable throughout shelf life?

SOD activity is measured using a validated enzyme activity assay (typically the xanthine oxidase/cytochrome c method or the NBT reduction method), expressed in International Units per gram (IU/g). SOD is a protein-based enzyme and is sensitive to heat, moisture, and oxidation. Our manufacturing process uses low-temperature extraction and controlled drying to preserve enzymatic integrity. Accelerated stability testing supports a 24-month shelf life under recommended storage conditions (cool, dry, sealed, away from light).

Q3: Is your Rosa Roxburghii Fruit Extract water-soluble? Can it be used in clear beverages?

Yes. Our standard grades are water-soluble and suitable for beverage applications. Clarity in solution depends on the grade and concentration - we recommend requesting a sample for dissolution testing at your target use level before finalizing your formulation. Our technical team can advise on optimal solubilization conditions.

Q4: Do you offer organic-certified Rosa Roxburghii Fruit Extract?

Yes. We offer USDA NOP and EU Organic certified grades. Organic certification documentation is available upon request. Organic grades carry a slightly longer lead time - please confirm availability with our sales team at the time of inquiry.

Q5: What regulatory status does this ingredient hold in the US and EU markets?

In the United States, Rosa roxburghii fruit extract is used as a dietary supplement ingredient under DSHEA. It is not currently listed as a Novel Food in the EU, but regulatory status can vary by specific application and claim. We strongly recommend consulting with your regulatory affairs team for market-specific compliance guidance. We can provide supporting documentation - including botanical identity verification, safety data, and historical use records - to assist your regulatory submission.

Q6: Can you provide a custom potency grade not listed in your standard range?

Yes. Custom grades - including higher SOD activity (≥10,000 IU/g), higher vitamin C content (≥20%), or specific polyphenol profiles - are available through our OEM/ODM program. Minimum order quantities and lead times for custom grades vary. Contact our technical team with your target specification to receive a feasibility assessment and quotation.

Q7: How do I verify that the SOD activity on your COA is accurate and not inflated?

Every COA we issue is batch-specific and generated by our in-house analytical laboratory using validated methods. We provide retained samples with every commercial shipment, enabling independent third-party verification at any ISO 17025-accredited laboratory. We actively encourage third-party testing - it is the most direct way to verify our data integrity. Suppliers who discourage independent testing are the ones worth questioning.

Q8: What is the recommended dosage range for dietary supplement applications?

Published research and commercial formulation practice generally support a daily dose range of 200–600 mg of standardized Rosa Roxburghii Fruit Extract for dietary supplement applications, depending on the grade and the targeted functional outcome. For SOD-standardized grades, a dose delivering ≥1,000 IU SOD activity per serving is a common formulation target. We recommend working with your clinical or regulatory team to establish the appropriate dose for your specific product and claim.

At Jiuyuan Biotech, we supply Rosa Roxburghii Fruit Extract in HPLC-verified, cGMP-manufactured grades - backed by 12 international certifications, batch-specific COAs, and a technical team ready to support your formulation from sample to scale.
