Production Process (Enzymatic Conversion):

1. Raw Material Preparation:

• Soy or sunflower lecithin extraction

• Degumming and purification

• Quality testing for phospholipid profile

2. Enzymatic Conversion:

• Phospholipase D enzyme catalysis

• Reaction with L-serine

• pH control: 5.5-6.5

• Temperature: 35-45°C

• Reaction time: 4-8 hours

3. Purification:

• Solvent extraction to remove byproducts

• Column chromatography for enrichment

• Multiple purification steps to achieve target PS content

4. Drying & Standardization:

• Vacuum drying at < 50°C

• Standardization to target PS percentage

• Quality testing and packaging

Key Parameters:

• Enzyme activity: Critical for conversion efficiency

• Serine ratio: Optimized for maximum yield

• Solvent system: Food-grade solvents only

• Yield: 60-80% depending on target purity

Quality Testing Methods:

• PS Content (HPLC-ELSD):

• Column: Silica gel column

• Mobile phase: Chloroform/Methanol/Water with ammonium acetate

• Detector: Evaporative Light Scattering Detector (ELSD)

• Quantification: External standard method

• Phospholipid Profile:

• HPLC analysis for PC, PE, PI, PA content

• Ensures correct phospholipid composition

• Heavy Metals: ICP-MS (Pb ≤ 2.0 ppm, As ≤ 1.0 ppm, Hg ≤ 0.1 ppm, Cd ≤ 0.5 ppm)

• Solvent Residues: GC analysis per USP <467>

• Microbiological: TP ≤ 1,000 CFU/g, Mold/Yeast ≤ 100 CFU/g, Pathogens negative

• Allergen Testing: ELISA for soy/sunflower protein residues

• Non-GMO: PCR testing for GMO markers (sunflower source)

Applications & Dosage:

• Cognitive Support Supplements:

• Adult brain health: 100-300mg PS per day

• Senior cognitive support: 200-400mg per day

• Often combined with Omega-3, Ginkgo, or B-vitamins

• Children's Focus & Attention:

• Age 6-12: 50-100mg per day

• Supports learning and concentration

• Gummy or liquid formulations preferred

• Stress Management Formulas:

• 100-200mg PS per day

• Often combined with Ashwagandha, L-Theanine

• Supports healthy cortisol levels

• Sports Nutrition:

• 200-400mg before/during exercise

• Reduces exercise-induced cortisol

• Supports recovery and reduces muscle soreness

• Functional Foods:

• Brain health beverages: 50-100mg per serving

• Smart snacks: 25-50mg per serving

• Infant formula (DHA + PS synergy): Specialized grades

Formulation Tips:

• PS is lipophilic - best absorbed with meals containing fat

• Softgel capsules provide excellent bioavailability

• Can be emulsified for liquid formulations

• Stable at pH 4.0-8.0

• Avoid high temperatures (>80°C) during processing
