Overview
1,3-Dioleoyl-2-palmitoylglycerol (OPO) is a structured triglyceride designed to closely mimic the fatty acid composition and positional distribution of human milk fat. In human breast milk, palmitic acid is predominantly esterified at the sn‑2 position of the triglyceride backbone, which facilitates efficient absorption of both fatty acids and calcium. OPO‑enriched infant formulas provide a more natural fat profile, improving nutrient absorption, reducing constipation, and supporting healthy growth and development in infants.

Key Benefits

• Mimics human milk fat: Structured triglyceride with palmitic acid at the sn‑2 position, similar to breast milk.

• Improved calcium absorption: Reduces the formation of insoluble calcium soaps, enhancing calcium uptake and bone health.

• Better fat absorption: Promotes efficient digestion and absorption of fatty acids.

• Reduced constipation: Softens stools and improves gastrointestinal comfort in infants.

• Supports growth: Provides balanced nutrition for healthy infant development.

• High purity and quality: Meets strict specifications for use in infant formula.

Applications

• Infant formula: Added as a functional lipid component to improve fat and mineral absorption.

• Follow‑on formulas: Used in formulas for older infants and young children.

• Specialized nutrition: Included in products for preterm infants or those with digestive sensitivities.

• Dietary supplements: Used in nutritional supplements for pregnant and lactating women.

Recommended Use
Typical usage levels in infant formula are determined by the desired fat composition. The product should be formulated to achieve a final fat profile that meets regulatory and nutritional requirements.

Handling and Storage

• Store in a cool, dry place, away from direct sunlight, heat, and moisture.

• Keep containers tightly sealed to prevent oxidation and contamination.

• Use appropriate personal protective equipment (gloves, dust mask) when handling.

• Shelf life: typically 24 months under recommended storage conditions.

Packaging
Available in 25 kg bags, drums, or custom packaging upon request.

Quality Assurance
Each batch is tested for OPO content, 2‑palmitoyl content, acid value, peroxide value, and heavy metals to ensure compliance with food safety standards.
