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.
