Cashew nuts in natura were crushed and subjected to lipid extraction using pressurized propane. There was variation in the temperature (30–60°C) and percentage of the cosolvent ethanol (0–6 %) using a 2² factorial design with central point in three replicates. The lipid composition was determined and compared to the composition of the ethereal extract obtained by Soxhlet method (SE). The amount of oil extracted ranged from 19.2 to 33.1 %. The extraction performed under the conditions of 8 MPa, 60°C using 6 % ethanol corresponded to 83.7 % of the total lipids. The higher the temperature and percentage of ethanol in the propane, the higher the extraction yield. Thirteen fatty acids were quantified, among them, oleic and linolenic acid were predominant. Tocopherols and sitosterol were higher in the oils obtained using pressurized propane and ethanol. The mathematical model of Sovová was adjusted to the kinetic curves of extraction and represented them satisfactorily.

腰果中NATURA将其压碎并使用加压丙烷进行脂质提取。使用中心点为2²的因子设计，在三个重复中，温度（30–60°C）和助溶剂乙醇的百分比（0–6％）会有变化。测定脂质组成并将其与通过索氏提取法（SE）获得的醚提取物的组成进行比较。提取的油量为19.2％至33.1％。在60℃，8 MPa的条件下，使用6％的乙醇进行萃取，相当于总脂质的83.7％。丙烷中乙醇的温度和百分比越高，萃取收率越高。定量了13种脂肪酸，其中以油酸和亚麻酸为主。使用加压丙烷和乙醇制得的油中生育酚和谷固醇含量较高。
