Oil yield and compressibility modeling during microscale expression: Criteria for linseed breeding

Abstract

Seven linseed varieties were harvested at seven times before complete maturity. Microscale oilseed expressions were subsequently carried out on it. A pressure of 10 MPa was applied for 1 h under uniaxial stress. The results were characterized in terms of oil, water and mucilage content, harvest date and oil yield. The piston displacement versus time (creep curves) was described by a four-Kelvin-Voigt elements viscoelastic model. Parameters were derived from the model, such as the mechanical properties of seeds (compressibility moduli), showing that the viscoelastic model fits well the experimental data (R 2 < 0.999). The modeling parameters were combined with some biochemical data in order to predict the kinetics of oil extraction.

Oilseeds sorption isoterms, mechanical properties and pressing: Global view of water impact

“…The micropressing was performed at 50°C after ½ hour warm-up of 3.17 g of crushed seeds. Details of the experimental method were described previously (Savoire et al 2008). …”

Development and characterization of flax fiber reinforced biocomposite using flaxseed oil‐based bio‐resin

“…Flaxseed oil is also known as linseed oil in most part of the world . Flaxseed oil has been studied by many researchers for its drying properties for commercial applications such as in oil‐based paints, varnish, putty, and linoleum . Sunflower oil, castor oil, and linseed oil have been investigated for their potential for polyurethane production for paint formulation .…”

Ultrasound‐assisted extraction of oil from hempseed (Cannabis sativaL.): Part 1

“…The oilseed cake is assimilated to a porous medium. 23 In screw pressing, the oiled solid is propelled by the screw and compressed by gradually reducing the volume available to the material. 24 The process is pressure driven and involves the flow of oil through the porous bed.…”
