Rosemary Extract Factory

Our rosemary extract powder is produced with carefully picked dry leaves of Rosmarinus officinalis L. extracted using state-of-the-art technology to preserve the maximum efficacy. This brown-yellow powder standardised to 10% Carnosic Acid content by HPLC analysis is a naturally occurring benzenediol abietane diterpene with better fat soluble phenolic characteristics. Our refined rosemary extract formulation is a unique solution for oxidative problems of food, nutritional supplements and cosmetic industry . The substance is excellent at stabilising Omega-3 fatty acids and avoiding heat deterioration in frying oils and also helps meet regulatory requirements to substitute synthetic antioxidants while retaining your final goods at ideal sensory levels.

Rosemary Carnosic Acid Advantages

Enhanced Antioxidant Action: Our extract employs a unique cascade mechanism wherein Carnosic Acid is transformed into Carnosol upon oxidation, keeping strong antioxidant activity and offering twofold protection from lipid peroxidation throughout the life cycle of your product.

Great Thermal Stability: Able to endure processing temperatures of 190°C-200°C for brief periods of time, so your production processes are not compromised in ingredient effectiveness, especially beneficial in extrusion and spray-drying.

Clean Label Compliant: Known as E392 in European countries, our natural extract helps you achieve clean-label certification while satisfying customer demand for recognisable, plant-based ingredients without synthetic BHA, BHT, or TBHQ.

Sensory Neutrality: Our purified chemical, unlike essential oil-based alternatives, does not possess strong camphoraceous odours, maintaining the true taste and scent profile of your final food and beverage applications.

Lipophilic Efficiency – Soluble in oils, fats and organic solvents, ensuring ease of incorporation into lipid-based matrices, offering optimal protection where oxidation issues are most crucial in your manufacturing environment.

Product specification

Application of Rosemary Carnosic Acid

Edible Oil Stabilisation: Our product stops rancidity in high-PUFA oils (fish oil, algal oil, flaxseed oil) during spray-drying microencapsulation procedures, providing induction time much beyond mixed tocopherol performance criteria.

Meat Processing Solutions Dual-function protection reduces lipid oxidation responsible for warmed-over flavour and ensures brilliant red colour stability in processed meat products. Effective in high salt/high fat systems such as sausages and cured meats.

Nutraceutical Formulations: Keeps fragile Omega-3 formulations stable during storage so your consumers enjoy the full nutritional benefits of the product and extends the shelf-life of the product without affecting the integrity of the capsule or flavour.

Cosmetic Uses: Rosemary Carnosic Acid's MMP inhibitory characteristics are used in anti-aging creams and sunscreen compositions to prevent collagen structures from UV-induced damage and to keep the emulsion oil phase stable throughout distribution channels.

Manufacturing Process

Step 1 – Raw Material Selection Rosemary leaves, carefully picked from our approved planting bases, are first screened for quality. Result: Only premium-grade botanical material with the best diterpene content enters our manufacturing stream.

Step 2 – Solvent Extraction Cleaned leaves are extracted under regulated conditions using food-grade ethanol or supercritical CO2 technology. Result: Highest yield of carnosic acid, preserving molecular integrity and removing undesirable chemicals.

Step 3 - Purification & Concentration Advanced chromatography techniques are used to run the extract and isolate certain compounds. Result: Accurate carnosic acid concentration to suit your exact needs ranging from 10% to 95%.

Step 4 - Quality Testing: Every batch receives comprehensive HPLC analysis alongside contaminant screening in our SGS-standard laboratory. Result: Complete COA documentation ensuring regulatory compliance and consistent quality standards.

Step 5 - Standardized Packaging: Purified powder receives double-layer PE bag protection within fiber drums in our 3,000-square-meter climate-controlled warehouse. Result: Product stability maintained throughout global distribution to your facility.

Third Party Test Report

Independent Verification Standards: Our goods are tested by independent, third-party accredited organisations such as SGS, Eurofins, etc., ensuring 100% conformity to international standards.

Pesticide Residue Analysis: Comprehensive screening satisfies the standards of EU Regulation 396/2005, guaranteeing that no dangerous agricultural chemical residues affect the end consumer’s product safety.

Heavy Metal Detection: We rigorously test to ensure that there is no Lead, Arsenic, Cadmium, and Mercury beyond the established safety levels, keeping your brand image and your consumers’ health safe.

Microbiological safety: All batches are certified free from Salmonella and E. coli and overall plate counts are kept below 1000 CFU/g to fulfil the most rigorous food safety standards.

Contaminant Screening: Extensive testing removes the worry about Polycyclic Aromatic Hydrocarbons (PAHs) and phthalate plasticisers assuring pharmaceutical-grade purity for purity-sensitive applications.​​​​​​​
