The first step involves cooking the fish material, which helps to coagulate proteins and facilitates the separation of solids from liquids. This sophisticated thermal separation process occurs under a vacuum, which lowers the boiling point of the compounds.
Ensuring Purity and Potency in Fish Oil Production
This step is vital for purifying the oil to pharmaceutical grade, ensuring that the final product is safe for consumption and free from environmental toxins that accumulate in marine ecosystems. These vapors then travel across a condenser where they cool and separate from contaminants like heavy metals, dioxins, and polychlorinated biphenyls (PCBs).
This cake often consists of protein-rich material that is subsequently dried and ground into a fine flour, commonly used as an ingredient in animal feed or aquaculture pellets. While historically derived from large predatory fish like tuna and swordfish, modern production predominantly utilizes smaller, oily fish such as anchovies, sardines, and mackerel.
Ensuring Purity and Potency in Fish Oil Production
Fish oil is celebrated for its high concentration of long-chain omega-3 fatty acids, specifically eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Molecular Distillation: The Critical Purification Step Perhaps the most critical phase in manufacturing how is fish oil made is molecular distillation.
