Due to increased regulations as a result of the 1990 Clean Air Act and potential health risks, the edible-oil extraction industry urgently needs an alternate hydrocarbon solvent to replace hexane. Solvent extraction is an integrated process involving five key unit processes: the solvent extractor, meal desolventiser, meal dryer/cooler, miscella distillation and solvent recovery. 13. The advantages of pure mechanical extraction are lower initial investment costs, higher-value edible oil and meal, and a safer and less complex operation. Coconut is extracted by dry and wet process. The main limitations of this process appear to be: (1) lower efficiency of oil extraction as evident in earlier studies, (2) demulsification requirements to recover oil when emulsions are formed, and (3) treatment of . This procedure is repeated various times until all non-volatiles are removed from the plant material.
The next step is to crack the seeds for size reduction, they are then flattened to form flakes which . Edible oil producers and food processors are seeking fast and non-destructive way to analyze fats and oils for process and quality control purposes. Box 1364, Minneapolis, MN 55440 USA.
