“…For example, De Haan et al [9,10] introduced gas-assisted mechanical expression (GAME) to increase oil-extraction yield and to reduce the effective mechanical pressure applied on the seeds using CO 2 assistance. New research work {e.g., Mhemdi et al [11]} investigated the pre-treatment of sugar beets with PEF to facilitate the expression process.…”

This review presents useful and green techniques of solvent-free extraction used in ancient times, such as extraction of olive oil and citrus essential oil, and innovative techniques, such as pulsed electric field, microwave, instantaneous controlled pressure drop, and extrusion. We discuss the devices, their applications, mechanisms, and parameters influencing sample preparation prior to analysis of natural products.

“…The contribution of this effect increases with increasing solubility of the CO 2 in the oil. Furthermore, the dissolved CO 2 reduces the viscosity of the oil, which could increase the oil yield [32]. CO 2 is easily removed from the cake and oil by depressurization, while some additional oil is removed by entrainment in the gas flow.…”

“…The first advantage of GAME is the increased yield at lower mechanical pressure. Compared with supercritical extraction, the amount of CO 2 that has to be recycled is reduced by two orders of magnitude, from typically 1 kg/kg [32] to 100 kg of CO 2 per kilogram [33] of seeds. Therefore, Figure 1.…”

Biodiesel has gained worldwide popularity as an alternative energy source due to its renewable, non-toxic, biodegradable and non-flammable properties. It also has low emission profiles and is environmentally beneficial. Biodiesel can be used either in pure form or blended with conventional petrodiesel in automobiles without any major engine modifications. Various non-edible and edible oils can be used for the preparation of biodiesel. With no competition with food uses, the use of non-edible oils as alternative source for engine fuel will be important. Among the non-edible oils, such as Pongamia, Argemone and Castor, Jatropha curcas has tremendous potential for biodiesel production. J. curcas, growing mainly in tropical and sub-tropical climates across the developing world, is a multipurpose species with many attributes and considerable potentials. In this article, we review the oil extraction and characterization, the role of different catalysts on transesterification, the current state-of-the-art in biodiesel production, the process control and future potential improvement of biodiesel production from J. curcas.

“…However, these techniques are often associated with major drawbacks restricting their wide application in the food industry. For instance, some of these techniques could adversely affect the sensory properties of the nuts (Zook 1992), their chemical composition (Gaur et al 2007) and their shape and texture (Sriti et al 2011), not to mention that they could be relatively low in efficiency, excessively costly (Venter et al 2006) and sometimes non eco-friendly and polluting to the environment.…”

Color and texture of low-calorie peanuts as affected by a new oil extraction process named “Mechanical Expression Preserving Shape Integrity” (MEPSI)

The current healthy life style pushed to develop and implement a novel efficient defatting process of high quality called BMechanical Expression Preserving Shape Integrityt hat conserved the sensory, color, textural, morphological and acceptability of partially defatted roasted peanuts. In this study, Response Surface Methodology was used to investigate the best extraction parameters (initial water content, pressure and pressing duration) based on the highest Color Consumer Evaluation scores, the best colorimetric parameters (L*, a*, b*, ΔE*) and the most appealing textural attributes (Fracturability, First Fracture Work Done, First Fracture Percentage of Deformation, Rupture Force, Percentage of Deformation at Rupture). Experimental results showed that defatting promotes a lighter and neutral grain color, higher fracturability and rupture force as well as higher deformation strength. Aiming to retain most of the colorimetric and textural properties after defatting and roasting, it was found that peanuts should be hydrated to 7 % d.b. and treated at 4.74 MPa for 14.22 min.
