An Onion Oleoresin Extraction Plant is designed to produce concentrated oleoresin from dried onion, capturing its strong flavor and characteristic aroma in a stable, liquid form. The process starts with cleaning, slicing, and drying fresh onions to reduce moisture content, followed by grinding into a fine powder. This powder is then subjected to solvent extraction—commonly using food-grade solvents like ethanol or hexane—to dissolve the volatile oils and flavor compounds. The extract is concentrated by evaporating the solvent under vacuum, resulting in a thick, yellow-brown oleoresin rich in sulfur-containing compounds like allyl and propyl disulfides, which give onion its pungency. The plant typically includes dryers, pulverizers, extraction vessels, solvent recovery units, evaporators, filtration systems, and packing machines. Onion oleoresin is widely used in the food industry for seasoning soups, sauces, snacks, and meats. The facility must maintain careful control over temperature and solvent handling to preserve flavor and ensure food safety.
