Rosemary Extract is a highly active ingredient made from natural rosemary leaves through supercritical CO₂ extraction technology. The core ingredient, carnosic acid, has a content of ≥5%-20% (customization is supported). Its antioxidant capacity is 3-4 times that of artificial synthetic preservatives (such as BHT and BHA), and it is safe and non-toxic, and complies with global mainstream market regulations (FDA, ECOCERT, ISO, etc.), making it an ideal natural solution to replace synthetic preservatives.
Core selling point: the “golden value” of carnosic acid
✅ Strong antioxidant: Carnosic acid can quickly neutralize free radicals, delay oil oxidation and rancidity, and extend the shelf life of food (experimental data: adding 0.02% rosemary extract can increase the oxidation stability of edible oil by 80%+)
✅ Natural preservation:Inhibit common pathogens such as Escherichia coli and Staphylococcus aureus, reduce the amount of chemical preservatives, and meet the trend of clean labels.
✅ Multi-scenario adaptation: High temperature resistance (stable below 260°C), good oil solubility, suitable for fried foods, baked oils, meat products, health care products and other fields.
✅ Synergistic enhancement: Compounded with natural antioxidants such as vitamin E and tea polyphenols, the effect is increased by more than 50%, helping customers reduce comprehensive costs.
The core functions of carnosic acid
Strong Antioxidant
Carnosic acid is a natural antioxidant, and its antioxidant capacity is significantly better than synthetic antioxidants (such as BHT, BHA) and vitamin E, especially in high temperature (stable below 260℃) and oil system. It can neutralize free radicals, delay oil oxidation and rancidity, and extend the shelf life of food. It is widely used in fried foods, baked oils, meat products and other fields.
Antibacterial and antiseptic
It has an inhibitory effect on common pathogens such as Escherichia coli and Staphylococcus aureus, and its antibacterial activity is better than some antibiotics (such as erythromycin). This feature allows it to replace chemical preservatives in food preservation and cosmetics preservation systems, meeting the "clean label" trend.
Cardiovascular protection
Through antioxidant and anti-inflammatory effects, it can reduce blood lipids and blood pressure, prevent atherosclerosis, and protect cardiovascular health. Studies have shown that it may reduce the risk of cardiovascular and cerebrovascular diseases.
Anti-tumor potential
Experiments have shown that carnosic acid can inhibit the proliferation of tumor cells (such as leukemia HL-60 cells) and may exert anti-cancer effects by regulating the cell apoptosis pathway, and has drug development potential.
Neuroprotection and anti-aging
Eliminating free radicals delays cell aging, improves cerebral blood flow and promotes nerve cell regeneration, and has a potential role in preventing neurological diseases such as Alzheimer's disease and Parkinson's disease.
Regulating metabolism and weight control
By inhibiting fat absorption and regulating glucose metabolism, it assists in weight loss and lipid reduction, and has certain benefits for obese and diabetic patients.
Anti-inflammatory and immune regulation
Relieves chronic inflammation (such as sore throat, arthritis), enhances immunity, and is suitable for auxiliary treatment of inflammation-related diseases
Application Areas & Solutions
Food industry
Oils & Fried Foods: Extend the life of frying oil and suppress the rancid smell of products such as potato chips and instant noodles
Meat products: Reduce the amount of nitrite and maintain the color and flavor of meat

Demand matching: Added in anti-aging skin care products (such as antioxidant essences and anti-wrinkle creams), suitable for people with sensitive skin and those who are looking for natural ingredients and those who are trying to prevent premature aging.
Recommended usage
1.Food Industry
Antioxidant and antiseptic
Oils and fried foods: The recommended addition amount is 0.02%-0.1% (based on the total amount of oil), which can significantly extend the shelf life of frying oils and fried foods and improve oxidative stability by more than 80%.
Meat products: Add 0.01%-0.05% to reduce the amount of nitrite, inhibit fat oxidation and keep the meat bright.
Baked goods: Add 0.02%-0.08% to bread and biscuits to delay rancidity and improve dough texture.
Condiments and sauces: Add 0.01%-0.03% to inhibit microbial growth and flavor deterioration.
2. Medicine and health care products
Auxiliary treatment of cardiovascular disease: Clinical studies recommend a daily intake of 50-200 mg (on the doctor's advice), which regulates blood lipids through antioxidant and anti-inflammatory effects.
Anti-tumor research: The experimental dose is mostly 20-40 mg/kg (animal model), and the human equivalent dose needs further verification.
Health care product preparations: The content of carnosic acid in capsules or tablets is usually 5%-20%, and the recommended daily intake does not exceed 300 mg.
3. Cosmetics and skincare products
Antioxidant and anti-aging products: The addition amount is generally 0.1%-1% (such as essence, cream), which can be used in conjunction with vitamin E to enhance the effect.
Natural preservative system: When replacing traditional preservatives, it is recommended to add 0.05%-0.2%, and other natural antibacterial ingredients must be used.
4. Feed and pet foods
Animal feed: Add 0.02%-0.1% to replace chemical antioxidants such as ethoxyquin, in compliance with EU REACH regulations.
Pet food: 0.01%-0.05% is recommended to improve fat stability and extend shelf life.
5. Other industrial applications
High temperature processing field (such as industrial oils and coatings): Add 0.5%-2% to take advantage of its high temperature resistance (stable below 260°C).
Plant extract compounding: When compounding with tea polyphenols and vitamin C, it is recommended that carnosic acid account for 10%-30%, which can enhance the comprehensive antioxidant effect.
Notes
Regulatory compliance: Different countries/regions have different standards for addition (such as China GB 2760-2011, EU EC No 1333/2008), and the dosage needs to be adjusted according to the target market.
Formulation selection: Powdered formulations are suitable for dry mixing processes, while liquid formulations are more suitable for oil systems. The concentration needs to be optimized according to the process
