| Összefoglaló≠ | 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. |
