Value of hydroalcoholic treatment of rapeseed for oil extraction and protein enrichment
This study investigated alternative solvents: ethanol and isopropanol, to replace hexane and enhance the quality and value of oil and meal. Rapeseed oil extraction was carried out using ethanol (92 wt.% or 96 wt.%), isopropanol (84 wt.% or 88 wt.%) or hexane (as reference). Results show that hydroal...

description | This study investigated alternative solvents: ethanol and isopropanol, to replace hexane and enhance the quality and value of oil and meal. Rapeseed oil extraction was carried out using ethanol (92 wt.% or 96 wt.%), isopropanol (84 wt.% or 88 wt.%) or hexane (as reference). Results show that hydroalcoholic extraction increased meal protein content by 13% compared to hexane extraction, but without significant influence of alcohol and water content. However, increasing water content improved glucosinolate extractability. Isopropanol 84 wt.% eliminated most glucosinolates from the seeds, decreasing glucosinolate concentration by 49–73% compared to meals extracted by the other alcohols.
L’étude a porté sur l’expérimentation de solvants alternatifs à l’hexane : éthanol et isopropanol à différents degrés d’alcool, visant à la fois une bonne capacité d’extraction de l’huile et l’amélioration de la qualité du tourteau grâce à l’augmentation de la concentration en protéines et à l’élimination de composants antinutritionnels type glucosinolates. L’extraction du colza a été réalisée par de l’éthanol à 92 % m/m et 96 % m/m d’alcool, de l’isopropanol à 84 % m/m et 88 % m/m d’alcool ou de l’hexane (solvant de référence). L’extraction hydro-alcoolique a augmenté la teneur en protéines du tourteau de 13 % par rapport à l’extraction hexane, mais sans influence significativement de la nature de l’alcool ou de sa teneur en eau. L’augmentation de la teneur en eau du solvant a par contre augmenté l’élimination des glucosinolates. En particulier, l’isopropanol 84 % m/m a été le plus efficace, permettant de diminuer la teneur en glucosinolates du tourteau de 49–73 % par rapport aux autres alcools. |
