Technical Specifications

Fermentation & Production Process:

  • Raw Material: Premium non-glutinous rice (Oryza sativa)

  • Fungal Strain: Monascus purpureus (proprietary high-yield strain)

  • Fermentation Process:

    1. Rice washing and soaking (4-6 hours)

    2. Steaming at 121°C for 30 minutes

    3. Cooling to 30-35°C

    4. Inoculation with Monascus purpureus spores (0.5-1.0%)

    5. Solid-state fermentation at 28-32°C, 80-90% humidity

    6. Fermentation duration: 14-21 days

    7. Drying at 50-60°C to moisture < 10%

    8. Grinding and standardization to target Monacolin K content

  • Key Control Points:

    • Temperature control: Critical for Monacolin K production (optimal 28-32°C)

    • Humidity: 80-90% for optimal mycelial growth

    • Citrinin control: Proprietary strain selection + pH control (<100 ppb)

    • Monacolin K optimization: 0.2% - 5% (customizable)

  • Quality Enhancement:

    • Strain improvement through adaptive evolution

    • Co-cultivation techniques for enhanced bioactive profile

    • Low-temperature drying to preserve heat-sensitive compounds

Quality Testing Methods:

  • Monacolin K Quantification (HPLC-UV):

    • Column: C18 (250mm × 4.6mm, 5μm)

    • Mobile phase: Acetonitrile / 0.1% phosphoric acid (55:45)

    • Detection wavelength: 238nm

    • Flow rate: 1.0 mL/min

    • Column temperature: 30°C

    • Retention time: ~8 minutes

    • Quantification: External standard with Monacolin K reference standard

  • Citrinin Testing (Critical Safety Parameter):

    • Method: HPLC with fluorescence detection (FLD)

    • Excitation: 330nm, Emission: 500nm

    • LOD: < 10 ppb, LOQ: < 50 ppb

    • Acceptance: < 100 ppb (meets EU/US safety standards)

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

  • Aflatoxins: HPLC-FLD or ELISA (B1, B2, G1, G2 < 10 ppb total)

  • Microbiological: TP ≤ 10,000 CFU/g, Mold/Yeast ≤ 500 CFU/g, Pathogens negative

  • Identity Testing: Microscopic examination + DNA barcoding (optional)

Applications & Dosage:

  • Cardiovascular Supplements:

    • Cholesterol support capsules: 600-1200mg per serving (providing 2.5-10mg Monacolin K)

    • Combination formulas: With CoQ10 (100mg), Omega-3, or plant sterols

    • Extended-release tablets: 1200mg once daily

  • Functional Foods:

    • Fortified rice products: 1-5% red yeast rice powder

    • Health wines (traditional Asian formulations): 5-10% extract

    • Vinegar supplements: 2-5% extract

  • Traditional Medicine:

    • TCM formulations for "blood invigoration"

    • Combination with hawthorn, garlic, or ginkgo

Important Considerations:

  • Monacolin K is chemically identical to lovastatin - avoid combining with prescription statins

  • Recommended daily Monacolin K intake: 3-10mg (based on clinical studies)

  • Best taken with evening meal (cholesterol synthesis peaks at night)

  • CoQ10 supplementation recommended for long-term use (Monacolin K may deplete CoQ10)

  • Not recommended for pregnant/nursing women or individuals with liver conditions
