Extracts refer to concentrated products obtained by separating, purifying, and concentrating bioactive components from natural raw materials (plants, animals, marine organisms, microorganisms, etc.) via physical or chemical extraction methods. As core raw materials for dietary supplements, they are valued for their high bioactivity, targeted functional properties, and natural origin. Unlike raw material powders, extracts undergo standardized processing to enrich specific active ingredients, ensuring consistent quality and efficacy across batches.
Core technical characteristics: ① Extraction processes – common methods include CO₂ supercritical extraction (solvent-free, suitable for heat-sensitive ingredients like essential oils), water/ethanol co-extraction (cost-effective, retains multi-active components for herbal extracts), low-temperature extraction (prevents bioactivity loss), and maceration (for mild extraction of delicate ingredients). Post-extraction processes (filtration, chromatography, spray drying) further purify and shape the product into powder (most mainstream, 80-400 mesh) or liquid forms; ② Standardization requirements – active components are quantified and verified by HPLC/UV/GC (e.g., EGCG ≥50% in green tea extract, curcumin ≥95% in turmeric extract, silymarin ≥80% in milk thistle extract) to ensure batch consistency; ③ Quality control – strict limits on impurities: heavy metals (Pb/Cd/As) total
