Bio Oil Extraction Method With Improved Oil Recovery Rate By Using Cooling Process

Abstract: The present invention relates to a bio-oil extraction method with an improved oil recovery rate by using a cooling process. The bio-oil extraction method of the present invention, in which a process of cooling a suspension obtained by disrupting cells of a culture solution containing microalgae is further carried out, exhibits a high oil recovery rate, and does not comprise adding other additives to increase an oil recovery rate, thus enabling oil recovery and the use of remaining by-products as feed, whereby sustainable production is possible, and the recovered oil can be effectively used as a feed composition, a food composition, or the like.
