Description

1.Sn-2 DHA Algal Oil – Next-Generation Structured Omega-3 Ingredient

Sn-2 DHA Algal Oil is an advanced structured lipid ingredient designed for high-end nutrition applications. Through innovative enzymatic technology and precision refining processes, the DHA molecules are selectively positioned in the Sn-2 position of the triglyceride structure, significantly enhancing the biological efficiency of DHA absorption.
Compared with conventional DHA oils, Sn-2 structured DHA more closely resembles the natural lipid composition found in human breast milk. This structural similarity improves digestion and absorption efficiency, making it particularly valuable for infant nutrition and specialized medical nutrition products.
The product represents a new generation of DHA ingredients that support product upgrades for nutrition brands and enable the development of premium formulations targeting high-value markets worldwide.

2.High Sn-2 DHA Ratio for Enhanced Bioavailability

In triglyceride molecules, fatty acids can be located at three positions known as Sn-1, Sn-2, and Sn-3. Scientific research indicates that fatty acids located at the Sn-2 position are more efficiently absorbed during digestion.
Sn-2 DHA Algal Oil is specifically engineered so that a large proportion of DHA is positioned at the Sn-2 location.
Key structural advantages include:
• Sn-2 DHA ratio exceeding 51% of total DHA
• nearly double the typical industry level
• improved intestinal absorption efficiency
• lipid structure closer to breast milk DHA
• enhanced metabolic utilization
This structural advantage allows nutrition manufacturers to create highly differentiated DHA products that deliver improved functional benefits.

3.Patented Enzymatic Directed Esterification Technology

The unique structure of Sn-2 DHA Algal Oil is achieved using patented enzymatic directed esterification technology.
This advanced biotechnology platform enables precise placement of DHA molecules within the triglyceride structure, creating a targeted Sn-2 DHA distribution.
Key advantages of this enzymatic technology include:
• precise molecular structure control
• higher nutritional bioavailability
• preservation of natural lipid properties
• environmentally friendly enzymatic process
This proprietary technology has been granted a national invention patent and represents a significant advancement in omega-3 ingredient development.

4.Advanced Refining and Purification Process

Following enzymatic structuring, the oil undergoes a series of advanced refining steps to ensure exceptional purity and safety.
The refining process includes:
• hydration degumming
• alkaline neutralization (deacidification)
• winterization
• bleaching purification
• deodorization technology
This integrated refining process effectively removes impurities, oxidation byproducts, and undesirable odors while maintaining the structural integrity of DHA molecules.
The result is a highly purified DHA oil with excellent sensory quality and long-term stability.

5.Strict Contaminant Control

To meet international food safety requirements, the production process carefully controls potential contaminants and oxidation indicators.
Key quality characteristics include:
• extremely low peroxide value
• minimal oxidation products
• controlled trans fatty acid levels
• strict monitoring of 3-MCPD esters
• strict monitoring of glycidyl esters
These quality controls ensure that the product meets the stringent standards required for infant nutrition and specialized medical food applications.

Sn-2 DHA Algal Oil ≥50% (Structured Omega-3 TG) – Key Questions & Answers

1. What is Sn-2 DHA Algal Oil?

Answer:
Sn-2 DHA Algal Oil is a structurally optimized omega-3 triglyceride oil in which docosahexaenoic acid (DHA) is predominantly esterified at the sn-2 position of the glycerol backbone.
This structure mimics human milk fat, enhancing digestion, absorption, and bioavailability of DHA.

---

2. What does “≥50% Sn-2 DHA” mean?

Answer:
It means that at least 50% of the DHA content is specifically located at the sn-2 position of triglycerides, rather than randomly distributed.
This positional specificity is critical for improved lipid metabolism and nutrient uptake, especially in infants and clinical nutrition.

---

3. What are the advantages of Sn-2 structured DHA vs regular DHA oil?

Answer:
Compared to conventional DHA oils, Sn-2 structured DHA offers:

• Higher bioavailability

• Better absorption efficiency

• Reduced formation of calcium soaps in the intestine

• Improved fat digestion

• Closer composition to human breast milk lipids

---

4. What is the source of the DHA?

Answer:
The DHA is derived from marine microalgae through controlled fermentation, typically using strains such as Schizochytrium sp.
This ensures a sustainable, vegetarian, and contaminant-free omega-3 source.
