Introduction
Docosahexaenoic Acid (DHA) is a long-chain Omega-3 polyunsaturated fatty acid (C22:6 n-3) that serves as a primary structural component of the human brain, cerebral cortex, skin, and retina. Often referred to as "Brain Gold," it is essential for neurological development and function.
We offer two distinct product lines to meet your specific market positioning:
1.Algal DHA (Premium): Produced via fermentation of Schizochytrium sp. microalgae. It is Vegan, Sustainable, and free from ocean-borne contaminants (Hg / PCBs).
2.Fish DHA (Standard): Refined from deep-sea Tuna/Bonito oil. Cost-effective solution for general Omega-3 supplements.

Functions
1.Infant Neuro-development (Critical USP)
• Brain Structure: DHA comprises approx. 40% of the polyunsaturated fatty acids in the brain and 60% in the retina.
• Cognitive Growth: Clinical data supports that adequate DHA intake during pregnancy and infancy is correlated with improved psychomotor development, IQ scores, and visual acuity.
2.Cardiovascular Health
• Lipid Profile: Reduces blood triglycerides and improves the Omega-3 index.
• Endothelial Function: Supports arterial elasticity and helps regulate blood pressure.
3.Eye Health
• Retinal Function: Vital for the regeneration of rhodopsin (visual pigment). Protects against age-related macular degeneration (AMD).
Applications
• Infant Formula & Baby Food:
○ Algal Oil: The preferred source for infant milk to match the DHA profile of breast milk (clean flavor).
○ Micro-encapsulated Powder: For dry blending into follow-on formula and cereals.
• Dietary Supplements:
○ Prenatal Vitamins: Essential for fetal brain development.
○ Vegan Softgels: 40% Algal DHA oil for plant-based Omega-3 claims.
• Animal Nutrition (Feed Grade):
○ Enrichment: Adding Schizochytrium powder to cow/chicken feed naturally increases the DHA content in milk and eggs ("Omega-3 Eggs").
Flow Chart
1.Fermentation: Heterotrophic cultivation of Schizochytrium sp. in closed stainless steel tanks.
2.Harvesting: Separation of algal biomass.
3.Drying: Spray drying the biomass (for Feed Grade Powder).
4.Extraction (for Oil): Mechanical disruption and solvent-free extraction.
5.Winterization & Refining: Removing saturated fats and impurities to ensure clarity at low temperatures.
6.Deodorization: Molecular distillation to remove off-notes.
7.Standardization: Adding antioxidants (Tocopherols/Ascorbyl Palmitate).
8.Packaging: Nitrogen-flushed drums (Oil) or Aluminum Bags (Powder).

Method of Analysis of Lactoferrin
Gas Chromatography (GC) is utilized for fatty acid profiling (AOAC 996.06).
• Trans-esterification: Conversion of triglycerides to methyl esters (FAMEs).
• Column: Capillary column (e.g., DB-23) specifically designed for separating cis/trans isomers of polyunsaturated fatty acids.
• Quantification: Comparison against a certified C22:6 standard.
Reference Chromatogram of Lactoferrin Reference Substance
(Image Placeholder: GC Chromatogram of Algal DHA)
The chromatogram demonstrates a high purity profile where the DHA peak dominates. In Algal oil, EPA levels are typically very low, distinguishing it from Fish Oil (which usually contains both EPA and DHA).
Stability and Safety
Stability Studies
• Oxidation Risk: High unsaturation makes DHA prone to oxidation (rancidity).
• Our Solution: We use advanced Flash Distillation and add mixed Tocopherols (Vitamin E) immediately after refining.
• Shelf Life:
○ Oil: 12-24 months at <15°C (Refrigeration recommended).
○ Powder: 24 months in original package.
• Test Data: Samples stored at 4°C showed Peroxide Value < 5.0 meq/kg after 18 months.
Safety & Handling (MSDS Summary)
• Classification: GRAS (Generally Recognized As Safe).
• Storage: Store in tight, light-resistant containers. Flush with Nitrogen after opening.
• Handling: Clean up spills immediately.

FAQ
Why choose Algal DHA over Fish DHA?
• Sustainability: Algae is grown in tanks, not harvested from the ocean. No impact on marine ecosystems. • Purity: Naturally free from ocean pollutants (mercury, dioxins). • Dietary: Suitable for Vegetarians and Vegans. • Taste: Cleaner, less "fishy" flavor profile.
Can I use DHA Powder in tablets?
Yes. Our DHA Powder (10% or 20%) uses micro-encapsulation technology (starch or casein shell) that withstands compression pressure, preventing oil leakage in tablets.
What is the recommended dosage?
Global recommendations typically suggest 250mg of EPA+DHA per day for healthy adults, and 200-300mg of DHA specifically for pregnant/lactating women.
