摘要	Soxhlet Extraction is a continuous solvent extraction method developed by Franz Soxhlet in 1879 for determining fat and lipid content in foods. Using a specialized glassware apparatus, Soxhlet repeatedly cycles hot solvent through a food sample, extracting lipids with high efficiency. It remains the official standard method for fat determination in numerous food standards and is widely used in food analysis and quality control.	High-Performance Liquid Chromatography (HPLC) is an analytical technique that separates, identifies, and quantifies components in a complex food sample by passing the sample through a pressurized column packed with a stationary phase. Developed by Horváth in the early 1970s, HPLC enables rapid, sensitive measurement of nutrients, contaminants, additives, and bioactive compounds in food products with high precision and accuracy.	Karl Fischer Titration (KFT) is a precise analytical method for determining water content in food and pharmaceutical products. Developed by Karl Fischer in 1935, KFT uses a chemical reaction between water and an iodine-based titrant, allowing quantification of moisture with exceptional accuracy and sensitivity. KFT is the official gold-standard method for water determination in numerous food and pharmaceutical standards worldwide.	Supercritical Fluid Extraction (SFE) is a separation technique that uses a fluid held above its critical temperature and pressure — most commonly carbon dioxide — to selectively dissolve and remove target compounds from a solid or liquid matrix. Widely applied in food science, nutraceutical production, and the flavour and fragrance industry, SFE offers a solvent-efficient, thermally gentle route to recovering oils, antioxidants, pigments, and bioactive compounds without the toxic residues associated with conventional organic solvents.
