• Medium Sterilisation: Fermentation medium comprising glucose solution, mineral salts, and micronutrients is sterilised by continuous or batch heat sterilisation before charging into the production fermenter
• Fermentation: Sterilised medium is inoculated with Aspergillus terreus inoculum and incubated under controlled aerobic conditions with regulated temperature, pH, dissolved oxygen, and airflow to maximise itaconic acid titre and volumetric productivity over the fermentation cycle
• Broth Clarification: At the end of fermentation, fungal mycelium is separated from the itaconic acid-containing broth by rotary vacuum filtration or filter press, producing a clarified broth suitable for downstream product recovery
• Decolourisation: Clarified broth is treated with activated carbon to adsorb coloured impurities, pigments, and organic contaminants, followed by carbon filtration to produce a water-white itaconic acid solution
• Evaporation and Concentration: Decolourised broth is concentrated under vacuum in multi-effect evaporators to achieve the supersaturation conditions required for efficient crystallisation of itaconic acid
• Crystallisation: Concentrated itaconic acid solution is cooled in vacuum crystallisers to induce crystallisation, producing a slurry of itaconic acid crystals suspended in mother liquor
• Centrifugation and Washing: Itaconic acid crystals are separated from mother liquor by centrifugation and washed with cold demineralised water to remove residual impurities and achieve the target purity specification
• Drying: Washed itaconic acid wet cake is dried in a spray dryer or fluidised bed dryer to achieve the specified moisture content and free-flowing powder characteristics of the finished product
• Quality Control and Testing: Finished product is tested for assay, moisture, colour, heavy metals, and residual solvent content before release for packaging and dispatch
