Rosemary Leaf Extract Powder

Rosemary Leaf Extract Powder - Premium Natural Antioxidant Solution

If you are looking for a natural antioxidant ingredient that you can trust, you have found it. Hunan Clover Origins Biotech's Rosemary Leaf Extract Powder is outstanding in quality and consistency. Our extract is standardized to include 5%, 10%, 20% or 50% Rosmarinic Acid (confirmed by HPLC) giving you the exact requirements you need for your formulations.

Our product is made from quality rosemary leaves (Rosmarinus officinalis L.) using advanced ethanol and water extraction, and is used in dietary supplement, functional food, natural food additive and cosmetic industries. With over 25 years of experience in botanical extracts and yearly production capacity of over 5,000 tons, we ensure batch-to-batch consistency and stable supply chain support. We are FDA registered, ISO 9001, FSSC 22000, Halal and Kosher certified so you can rest assured your products meet worldwide quality standards.

What Is Rosemary Leaf Extract Powder?

This concentrated botanical substance is significantly more than just powdered leaves. Using state-of-the-art solvent extraction and spray drying technology, we extract and concentrate strong bioactive ingredients like Rosmarinic Acid, Carnosic Acid and other polyphenols.

The extraction method eliminates the indigestible cellulose but retains the antioxidant chemicals you need. This generates a standard, shelf-stable ingredient that performs consistently from production batch to batch.

You will love the increase in bioavailability versus raw herb powders. The extract causes the cell walls to break down, releasing active substances which are actually absorbed and utilized by your consumers' bodies.

Product Specifications

Our standardized specifications ensure you receive consistent quality for reliable formulation development:

Technical Properties & Advantages

Rosemary Leaf Extract Powder provides unique technical benefits that alleviate typical formulation problems. The powder has shown good thermal stability, retaining its antioxidant action at high processing temperatures up to 200°C.

Depending on your application demands, you can work with different solubility profiles. Grades high in rosmarinic acid dissolve rapidly in water-based systems and are perfect for use in beverages and liquid supplements.

The natural brown color blends well with most formulas without causing visual discrepancies. Particle size distribution is important for seamless blending in capsule filling equipment and powder mixing.

Synergism with tocopherols or ascorbic acid is shown by our extract. This multiplier effect allows you to lower the overall antioxidant dosage and yet have a stable result.

Our product is compliant with clean-label standards. It is designated as a natural flavoring agent GRAS in the US and as E392 in the EU, so you can deliver on consumer demand for familiar ingredients.

Quality Control & Testing Protocols

We do a four-tier quality inspection to keep the integrity of the ingredients at every step.

Active Marker Quantification: Verify the HPLC assay to ensure your product's Rosmarinic Acid level is consistent with what is shown in your Certificate of Analysis. Each batch of production is tested individually.

Contaminant Detection: Strict testing procedures include Heavy Metals testing by ICP-MS (Lead <3.0ppm, Arsenic <1.0ppm, Mercury <0.1ppm) and Pesticide Residues testing by GC-MS/LC-MS. We screen for over 500 pesticides.

Microbiological Control: Tested to USP <61> <62> standards with rigorous limits: Total Plate Count <1,000 cfu/g, Yeast & Mold <100 cfu/g, and no Salmonella and E. coli.

Physical Analysis: testing for particle size distribution and bulk density to ensure constant flowability for your production equipment. We check that each batch meets mesh size specifications.

And with third-party validation from Eurofins, SGS and Alkemist Labs, you get independent verification you can trust. Complete traceability from raw material procurement to completed product to achieve total supply chain transparency.

Applications Across Industries

Dietary Supplements: Formulate antioxidant capsules, tablets and powdered blends that promote cellular health and immunological function. Our standardized extracts assure the same dose in each of your products.

Functional Foods & Beverages: Add functional benefits and organically extend shelf life. Water-soluble forms mix well into ready-to-drink formulas, protein powders and nutritional bars.

FAQ

Q: What's the difference between Rosmarinic Acid and Carnosic Acid extracts?

A: Water-soluble Rosmarinic Acid is excellent for beverages, liquid supplements, and water-based cosmetics. Carnosic Acid is fat-soluble and is ideal for use in fat-containing meals, oils and lipid-based products. We have both types customized for your application needs.

Q: How does your extract compare with tocopherols for food preservation?

A: Our rosemary extract is more thermally stable for high temperature processing such as baking, frying and extruding. It works synergistically with tocopherols to provide better antioxidant protection than either antioxidant alone, generally at a lower total dose.

Q: Do you offer organic or non-GMO certified options?

A: Yes, we do have certified organic rosemary leaves and we have segregated processing lines. We provide full documentation to meet your certification needs including organic certificates and non-GMO declarations.

Q: What is the expected shelf life and how should I keep the product?

A: Under proper storage conditions (sealed container, cool, dry environment away from direct light), shelf life is 24 months. We recommend temperatures around 25 °C and relative humidity under 60% to retain optimum stability.

Q: Is there technical support available for formulation development?

A: Certainly. Our technical staff will give you application recommendations, stability testing advice and dose recommendations based on your individual product matrix. We may carry out compatibility testing and pilot scale experiments to optimize your formulation.

Q: Is there any documentation for regulatory compliance?

A: All shipments are accompanied by Certificate of Analysis, third-party testing reports, allergen statements, GMO declarations, BSE/TSE statements, and applicable certifications (Kosher, Halal, organic). We also supply regulatory status documents for a number of markets.

Q: Do you do custom blends with other plant extracts?

A: Yes, we offer OEM/ODM services including unique compound formulation and premix creation. We can combine rosemary extract with complementary antioxidants, vitamins or other botanical extracts to develop customized ingredient systems.
