Beta-Carotene Oil 30% is a reddish-brown liquid and manufactured by fermentation technology.
Natural beta-carotene is obtained by a fermentation process using a mixed culture of the two sexual mating types(+) and (-) of natural strains of the fungus Blakeslea Trispora. The crystallised product consists mainly of trans beta-carotene. Because of the natural process, approximately 3% of the product consists of mixed carotenoids. The micronized beta-carotene crystalloids are evenly dispersed in sunflower oil and all-rac-α-Tocopherol is added as an antioxidant.

Flow Chart
Microbial Strain Development & Smart Fermentation System
1. Strain Screening & Optimization
Built a 3,000+ microbial strain library.
High-throughput screening via microfluidic chips (500 strains/day) identified Blakeslea trispora HSF-Bt07 with 3× higher β-carotene yield than wild strains.
Adaptive evolution (ALE) under stress (high osmotic pressure/low temperature) enhanced stability: 99% yield retention over 20 generations.
2. Light/Oxygen-Sensitive Fermentation System
Double-layer stainless steel bioreactor:
UV-resistant coating + nitrogen blanketing → dissolved oxygen ≤3% (vs. industry average 8%).
3. Dynamic control technology
Embedded sensors collect 12 parameters (pH, temperature, cell density) every 10s.
Machine learning-based feeding adjusts C/N ratio → cell density reaches 65g DCW/L (vs. 40g in traditional processes).
Two-Phase Fermentation:
48h biomass growth phase: 300% biomass increase.
Metabolic burst phase: Gradient temperature triggers β-carotene production at 10g/L.
Advantages
- Higher stability and bioavailability compared to synthetic carotenoids.
- Sustainable production via Blakeslea trispora fermentation.
- Aligns with clean-label and plant-based trends across industries.
Applications
1. Nutraceuticals & Dietary Supplements
Beta carotene liquid used as a natural source of β-carotene (provitamin A) for immune support, vision health, and antioxidant formulations. Incorporated into softgels, capsules, or liquid supplements for enhanced bioavailability.
2. Functional Food & Beverages
Added to juices, dairy products, and fortified snacks as a natural colorant (orange-red hue) and nutrient booster. Ideal for clean-label products replacing synthetic dyes (e.g., annatto alternatives).
3. Cosmetic & Skincare Products
Utilized in anti-aging serums, creams, and sunscreens for its antioxidant properties and UV-protection benefits. Enhances skin radiance and supports collagen synthesis in topical formulations.
4. Pharmaceutical Industry
Beta-Carotene Oil serves as a raw material for vitamin A production in medical supplements targeting deficiency-related conditions. Explored in formulations for photoprotective therapies or wound-healing applications.
5. Animal Feed Additives
Added to poultry/pet feed to improve feather/skin pigmentation and boost immune function in livestock.
