DHA Microencapsulated Powder

1.High Oil Load Omega-3 Ingredient for Infant Nutrition and Functional Foods

DHA (Docosahexaenoic Acid) is a critical long-chain Omega-3 fatty acid essential for human health. It is a major structural component of the brain and retina and plays a vital role in neurological development, cognitive function, and visual acuity.
In the human brain cortex, DHA accounts for approximately 40% of polyunsaturated fatty acids, while in the retina it represents nearly 60% of total fatty acids. Because of its physiological importance, DHA has become a key nutritional ingredient in infant formula, maternal nutrition, and functional food products worldwide.
To meet the strict quality requirements of the global nutrition industry, our DHA Microencapsulated Powder utilizes high-purity algal DHA oil produced from Schizochytrium sp. through patented fermentation technology. This sustainable microbial source eliminates risks associated with marine pollution and ensures a consistent and safe supply of Omega-3 DHA.

2.Advanced Microencapsulation Technology

The product is produced using a multi-stage encapsulation process:
2.1Precision emulsification
2.2High-shear processing
2.3High-pressure homogenization
2.4Spray drying encapsulation
Through optimized formulation and process control, the DHA oil is encapsulated within a stable protein matrix. This microcapsule structure protects DHA from oxidation and environmental degradation while maintaining excellent dispersibility in food systems.
The result is a high encapsulation efficiency powder with strong oxidative stability and good dissolution performance.
Key advantages include:
• High oil loading capacity (7%–20%)
• Excellent oxidative stability
• Good solubility and dispersibility
• Low odor and neutral taste
• Improved shelf life for finished products
These characteristics make it an ideal ingredient for demanding nutritional formulations.

3.Natural Triglyceride (TG) DHA Structure

The DHA in this product exists naturally in the triglyceride (TG) molecular structure, which is the same form commonly found in natural foods.
Compared with synthetic or ethyl ester forms, TG-form DHA provides several advantages:
• Higher biological absorption efficiency
• Better compatibility with human metabolism
• Improved nutritional value in food applications
This ensures the final product delivers optimal nutritional performance.

4.High Quality Algal Source

Our DHA originates from Schizochytrium microalgae cultivated through closed fermentation systems.
This production method offers several important advantages:
• No marine environmental contamination
• No food chain accumulation
• No heavy metal risk
• Controlled and traceable fermentation process
The microalgae fermentation process is environmentally friendly and utilizes renewable biological resources, making it a sustainable alternative to traditional fish-derived Omega-3 sources.

5.Full Industry Chain Quality Control

To ensure maximum quality and traceability, the entire production chain is integrated within a single manufacturing facility.
Production stages include:
• Algae strain cultivation
• Controlled fermentation
• Oil extraction
• Purification and deodorization
• Microencapsulation
• Powder processing
By controlling the full production chain in one location, batch-to-batch consistency and strict quality standards are guaranteed.
The facility operates under 100,000-class clean production standards, with each manufacturing step monitored under rigorous quality management protocols.

6.International Certifications and Regulatory Compliance

DHA Microencapsulated Powder complies with strict international regulatory and food safety requirements.
Certifications include:
• FDA GRAS approval for infant nutrition
• FDA GRAS approval for general food applications
• EU Novel Food authorization
• Halal certification
