Introduction
β-Carotene (Beta-Carotene) is a red-orange pigment found in plants and fruits, chemically classified as a terpenoid and a provitamin A carotenoid. It is the most potent precursor of Vitamin A among carotenoids.
Unlike synthetic alternatives, our β-Carotene is produced through controlled fermentation or natural extraction, ensuring high bioavailability and stability. It serves a dual purpose in the industry: as a potent antioxidant nutritional enhancer and a stable natural colorant (E160) for food, beverages, and supplements.

Functions
1.Potent Antioxidant Activity (MOA)
β-Carotene acts as a chain-breaking antioxidant. It quenches singlet oxygen and scavenges free radicals (ROS), thereby protecting cellular lipids from peroxidation.
• Cellular Protection: Mitigates oxidative stress which is linked to cellular aging.
• In Vivo Efficacy: Studies indicate dietary supplementation reduces oxidative damage to hair cells and hearing loss in murine models.
2.Pro-Vitamin A Conversion
• Metabolic Pathway: Enzymatically cleaved by beta-carotene 15,15'-monooxygenase in the intestinal mucosa to yield two molecules of Retinal (Vitamin A).
• Safety Valve: The conversion is rate-limited by the body’s Vitamin A status, preventing Vitamin A toxicity (hypervitaminosis A) often associated with direct Retinol intake.
3.Pigmentation
• Natural Coloring: Provides a vivid yellow-to-orange hue stable across a wide pH range.
Applications
Our β-Carotene is engineered for specific industrial applications:
• Dietary Supplements (Softgels/Tablets): Used for vision health (retina protection) and immune support formulations.
• Functional Foods & Beverages:
◯ Dairy & Margarine: Provides the standardized "buttery" yellow color.
◯ Beverages: Water-soluble (CWS) grades ensure clear dispersion without "ringing" in juices and energy drinks.
• Cosmetics: Acts as an anti-aging active ingredient to protect skin against UV-induced erythema.
• Feed Additives: Enhances yolk color in poultry and fertility in livestock.
Flow Chart
Riboflavin (Vitamin B2) → Phosphorylation (Flavokinase) → FMN (Flavin Mononucleotide) → Adenylylation (FAD Synthetase) → Reaction Termination → Filtration → Ion Exchange Purification → Salt Formation (Disodium) → Concentration → Lyophilization → Quality Control → Packaging
Note: Our enzymatic process mimics the natural biological pathway, avoiding the use of toxic condensing agents found in chemical synthesis.
Quality Standard of Lactoferrin
| Item | Specification | Result |
| Appearance | Orange-yellow to orange powder | Conforms |
| Assay (HPLC) | ≥ 93.0% (Anhydrous Basis) | 96.5% |
| Identification | UV / IR Spectrum | Conforms |
| Water Content | ≤ 10.0% (Hygroscopic) | 6.8% |
| pH (1% Solution) | 5.5 – 6.5 | 6.1 |
| Sodium (Na) | 5.0% - 7.5% | 5.8% |
| Heavy Metals | ≤ 10 ppm | < 5 ppm |
| Arsenic (As) | ≤ 1.0 ppm | < 0.2 ppm |
| Microbiology | ≤ 500 cfu/g | < 50 cfu/g |
Method of Analysis of Lactoferrin
We utilize Reverse-Phase HPLC with UV detection at 260nm and 450nm.
• Purity Ratio: We measure the absorbance ratio A260/A450 (typically 3.25 - 3.65) to confirm the integrity of the Adenine and Flavin moieties, ensuring the molecule is intact.

Stability and Safety
Stability Studies
FAD is extremely sensitive to light (photolysis).
• Storage: Store in amber glass vials or aluminum foil bags at 2-8°C (Refrigerated).
• Shelf Life: 24 months under cold, dark conditions.
• Light Warning: Exposure to light causes rapid degradation into Lumichrome. Always handle under low light or yellow light conditions in the lab.
Safety & Handling (MSDS Summary)
• Classification: Non-hazardous.
• Handling: Wear protective eyewear. Substance is a strong dye (stains skin/clothing yellow).
• Storage: Keep container tightly closed in a refrigerator.

FAQ
What forms of β-Carotene do you supply?
We offer a full range: • Powder (CWS): 1%, 10%, 20% (for beverages, soups, bakery). • Beadlets: 10%, 20% (for tablets, hard capsules). • Oil Suspension: 30% (for softgels). • Pure Crystalline: 96%+ (for R&D and specialized use).
Is your β-Carotene natural or synthetic?
We supply both Natural (Fermented from Blakeslea trispora) and Nature-Identical (Synthetic) grades to meet different labeling requirements and budget constraints. Please specify your preference when quoting.
How do you ensure the stability of β-Carotene?
Unprotected β-Carotene oxidizes rapidly. We use advanced micro-encapsulation technology (using starch, gelatin, or gum arabic matrices) to protect the molecule from oxygen and light, ensuring a 24-month shelf life.
