  • What is Standardized Rosemary Extract E392?

     

    Standardized Rosemary Extract E392 is a regulatory-compliant natural food preservative and antioxidant from Rosmarinus officinalis L. leaves. Standardized to lipid-soluble and water-soluble polyphenols, this plant-derived ingredient delivers exceptional oxidative stability and clean-label safety across commercial food, beverage, and nutraceutical supply chains.

    Green Spring Technology utilizes continuous countercurrent extraction and high-vacuum molecular distillation to manufacture this industrial-grade botanical ingredient in both standardized powder and liquid oil forms, ensuring seamless equipment compatibility for high-speed automated manufacturing lines.

    The oil-soluble series is standardized in Carnosic Acid (5% to 50%), functioning as a heat-resilient antioxidant to control peroxide values in bulk edible oils, fats, and industrial pet food, effectively replacing synthetic alternatives like BHA, BHT, and TBHQ.

    The water-soluble and specialized application series features high-purity Rosmarinic Acid (20%) and functional Ursolic Acid (25% to 98% powder), guaranteeing crystal-clear solution transmittance and zero discoloration interference in advanced beverages, dietary supplements, and premium cosmetics.

    Technical FAQ


    Q1: What are the primary formulation boundaries between Carnosic Acid, Rosmarinic Acid, and Ursolic Acid series?
    A1: Carnosic Acid (5%–50%) is lipid-soluble, optimized for controlling peroxide values in bulk edible oils, fats, and industrial pet food. Rosmarinic Acid (2%–20%) is 100% water-soluble, achieving ≥95.0% spectrophotometer transmittance in clear functional beverages. Ursolic Acid (25%–98% white powder) is targeted exclusively for skin-barrier soothing cosmetics, requiring organic solvent or liposomal carriers.


    Q2: How does Standardized Rosemary Extract E392 replace synthetic chemical alternatives like BHA, BHT, and TBHQ?
    A2: The active carnosic acid molecule undergoes radical scavenging mechanism transitions that resist thermal breakdown. It possesses a high smoke point and molecular structural lattice stability, allowing it to withstand commercial deep-frying and steam extrusion up to 180°C–200°C without active potency loss, delivering an effective plant-derived natural preservative alternative to synthetic chemical stabilizers.


    Q3: Does the usage of Standardized Rosemary Extract (E392) impact the visual clarity or sensory profile of clear beverages?
    A3: Utilizing the specialized water-soluble rosmarinic acid powder ensures zero browning or sedimentation. Precision extraction removes volatile essential oils and chlorophyll, resulting in a light-colored powder that guarantees no residual herbal aroma, browning discoloration, or bitter aftertaste across a fluid pH 3.0 to 7.0 formulation range.


    Q4: What specific regulatory standard clearances are guaranteed for international shipments of Bulk Rosemary Extract?
    A4: Every industrial lot is certified under BRCGS, IFS, FDA, Kosher, Halal, COSMOS, and EU/USDA Organic global standards. Batch-specific analysis protocols ensure 100% compliance with heavy metal thresholds (Pb ≤ 2.0ppm, As ≤ 1.0ppm, Hg ≤ 0.1ppm, Cd ≤ 1.0ppm under USP <2232> / EC No 1881/2006) and maximum residue limits (MRLs under EU EC No 396/2005 and USP <561>), verified via HPLC and independent validation by Eurofins and SGS.
