To correctly determine fat in feed and encapsulated oils, an additional acid hydrolysis might be required. OPSIS LiquidLINE provides a solution for Total Fat determinations.

To determine fat in fish feed is challenging – basic Crude Fat methods might give too low results. Crude fat is the free fat that can be extracted directly from a sample using solvent and that means the bound fat is not measured. In fish feed the bound fat might be a substantial part of the sample. Additional pre-treatment of the sample is necessary to give correct fat determinations.

Acid pre-treatment, i.e. acid hydrolysis, is a separate step necessary when determining the fat content in fish feed samples. The unique OPSIS LiquidLINE HydROC filter together with the HydROC and SoxROC units provides a good solution for this analysis.
