Rapid preparation of protein powder from high-moisture tuna liver: New insight into subcritical dimethyl ether

The subcritical dimethyl ether extraction (SDEE) was applied in the preparation of liver protein powder (LPD) in this paper. As expected, the lipids and water in tuna liver were co-removed by SDEE, and LPD with a high protein content could be obtained. Besides that, the maximal protein content (88.51%) of LPD was obtained by optimized extraction conditions (liquid-solid ratio 34 mL/g, time 70 min and stirring speed 945 rpm). Furthermore, the...
