Effect of mechanical press oil extraction processing on quality of linseed oil

Commercial Cold Pressed Flaxseed Oils Quality and Oxidative Stability at the Beginning and the End of Their Shelf Life

“…The acid value for studied flaxseed oils that were sold in New Zealand were in the range of 0.5-2.5 mg KOH/g. In our work oils were characterized by a very low content of peroxides primary oxidation products , forming in the range 0.6-1.0 mEq O 2 /kg 11 demonstrated the impact of the number of pressings on the quality of flaxseed oil. The smallest peroxide value they received for the oil pressed twice, probably due to greater amount of phenolic antioxidants that were extracted with the oil.…”

Hemp and flaxseed oil

“…A single screw expeller operating at a constant shaft speed was utilized to process flaxseeds (Kasote et al, 2013). The oil yield increased from 19.2% to 31.9% as the number of consecutive pressing steps increased (single, double, and triple pressing).…”

Biodiesel production from Sterculia striata oil by ethyl transesterification method

“…The authors obtained 78.6% extraction efficiency when they used the hydraulic system, but they did not provide any information about the extraction time. Kasote et al (2013) evaluated the press extraction of linseeds using a screw pressure machine; they obtained 19.2% yield in a single press process. The authors did not mention the extraction time, but they observed only slightly different yields when they compared double and triple pressed oil.…”
