This article constitutes the fifth part of a series dedicated to comparative analysis extraction solvents for oilseeds. section evaluates impact various on oil quality, focusing enzymatic activity, acidity, peroxide value, fatty acid profiles, phospholipids, polyphenols, tocopherols, and sterols. For alcohols, such as ethanol, isopropanol, methanol, results indicate an interesting suppression activity due protein denaturation. Alcohols also lead higher tocopherol content lower acidity when solvent recycling employs non-distillation process. Ketones, particularly acetone methyl ethyl ketone, show potential enzyme denaturation exhibit low miscibility with which may Ethyl acetate is recognized potentially enhancing extracting levels antioxidants. Dichloromethane effective in more phospholipids compared hexane. The use 2-methyloxolane (2-MeOx) presents issue formation, leading values extracted oils. Additionally, 2-MeOx extracts amounts but sterol reasons not fully understood. Regarding no study has shown significant effect choice. These highlight complex interactions between components, illustrated by surprising findings free acids alcohols. Despite substantial number studies, presented should be interpreted cautiously, they were obtained under conditions representative industrial operations.

Abstract Grain legumes such as pea, faba bean, lupin and soybean are an important protein source for the production of plant-based foods thus facilitate transition. For many food applications, proteins first isolated using conventional wet methods that resource intensive. Dry fractionation processes therefore developed to a more sustainable This review discusses status dry grain produce protein-rich ingredients how use these dry-enriched could be further enhanced. includes milling separation technologies which briefly described.

Oilseeds extraction of oils requires the use a processing aid : solvent. This seventh article on comparison solvents potentially capable replacing hexane presents multi-criteria analysis, systematically revisiting aspects from previous investigations. The methodology addresses problem’s complexity by aggregating different dimensions representative each criterion, resulting in nuanced ranking approach. comprehensive study examined critical including solvent extractive efficacy, operational safety, explosion risk, toxicity to workers, environmental impact, process modifications, energy consumption, effects products quality, residual toxicity, technology readiness level, and economic feasibility. From technical standpoint, today remains most efficient for oilseed crushers. Dichloromethane may be viable alternative due its non-explosive nature, though concerns are significant. 2-methyloxolane is subject ongoing research development investments, which ultimately establish it as credible solution. Different stakeholders present varied perspectives replacement. For worker isopropanol ethanol preferable options. Environmental advocates favor ethyl acetate because lower requirements during processing. Regarding food both generally regarded acceptable solvents. Public authorities, their part, must balance what desirable with feasible, framework balancing availability, cost global scale.

This study compares various solvents for edible oil extraction, focusing on their energy consumption impacts. The research examines traditional hexane and alternative solvents, using both theoretical calculations experimental data. article presents a thermodynamic analysis of solvent-water separation ChemSep software rectification simulations. Results show significant differences in requirements, with acetone being potentially the most efficient alcohols (ethanol isopropanol) requiring substantially more at desolventization step. Solvent hold-up marc is crucial factor affecting consumption. Experimental data from pilot plant rapeseed cake extraction presented, showing higher retention rates ethanol isopropanol compared to hexane. For other are estimated Hansen solubility parameter δh.

Alternative generally With hypothetical non-distillation scheme heat required +76% ethanol, +32% isopropanol, −21% acetone. It +42% miscella evaporation. Methyl ethyl ketone (MEK) would require +66%, acetate 33% 2-methyloxolane +35% heat. Dichloromethane isohexane little less because low boiling point while cyclohexane requires 5% more. also discusses implications choice desolventizer-toaster-dryer-cooler (DTDC) design operation, highlighting potential challenges high-moisture resulting intensive use direct steam.
