Edible insects have been considering as a rich resource of high-quality protein and lipid content and at the same time a low-cost nutritious resource acquiring the least expenditure during farming, breeding, rearing and harvesting. On the other hand, organic solvent consumptions in industrial areas need to be limited; being flammable by environmental hazards. That is why seeking for alternative non-toxic solvents is highly substantial. In this study ethanol-aqueous extraction method applied at three different levels to find the optimum yield of edible oil extracted of Homoptera Cicadidae Magicicada, a seasonal insect residing underground, which is consuming locally as a whole meal. These levels set using Design of expert software to variables as pH, ethanol-concentration and solvent/sample ratio and the maximum yield extracted respectively at 6, 50 and 5, by the yield of 19.5%, that is comparable to oil extracted by conventional hexane oil extraction method at 27%. Fatty acids profile of recent method and hexane extraction method analyzed using GC-MS method and the physicochemical properties of either alternative method investigated. The results were on the standard ranges. Fatty acid profile of HCM was for the most part consisted of oleic acid, following by palmitic and linoleic acid 66.5, 19.2 and 7.8 respectively in hexane extraction method and 66.3, 17.7 and 9.5 in ethanol aqueous extraction method. The Iodine Value of HCM oil was noticeably high which introduces a medicinal applicatory besides the rich amount of MUFAs and PUFAs essential oils that are well-known for their incredible health benefits.

“…On oil extraction from sunflower collets, ethanol gave a higher yield of extracted material, the content of oil phase was similar to that obtained when n-hexane is used. When ethanol was used, about 70% less crystallizable waxes and about 38% more tocopherols and phospholipids were extracted, this shows the feasibility of using ethanol as an alternative solvent to hexane in extracting oil (Baümler et al, 2016), including RBO (Oliveira et al, 2012;Rodrigues and Oliveira, 2010). Previously, Imsanguan et al (2008) have reported that ethanol was a better solvent for g-oryzanol extraction compared to hexane.…”

“…Some scientific reports on the benefits of RBO for health have led this study to evaluate the optimization of the extraction process of RBO. The direct solvent extraction method, which does not require specific extraction instrumentation, has been most commonly used (Chen and Bergman, 2005), and ethanol has gained attention as a potential solvent for vegetable oils (Rodrigues and Oliveira, 2010). Study on sesame oil revealed that the polar solvent such as ethanol was a good solvent compared to non-polar solvents.…”

Rice bran oil (RBO) extraction with ethanol using maceration method accompanied by stirring has been optimized using response surface methodology (RSM) based on central composite design (CCD). Experiments were conducted to investigate the influence of extraction time, ethanol concentration, and ethanol volume on the oil yield, g-oryzanol, and vitamin E of RBO as the response. The experiment consisted of twenty units including six replicates of the center points. The data were analyzed using Design-Expert 10 software to develop and evaluate models and to plot the response curve as 3D surfaces. The result showed that the maximum of the oil yield, g-oryzanol, and vitamin E of RBO was achieved under the optimum conditions of x 1 = 5.30 h, x 2 = 89.21% and x 3 = 686.66 mL (50 g rice bran), respectively. Maximum of the response under these conditions was 14.47%, 783.65 mg.L À1 , and 127.01 mg.L À1 , respectively. This study has resulted in the development of a model for RBO extraction using ethanol as solvent, it is feasible to be applied to the RBO industry with an efficient process, as well as an implementation of the "green" solvent concept.

Two independent variables (temperature and hydrolysis time) and oil recovery for objective function were used in order to obtain reliable information on these factors involved in the enzymatic hydrolysis processing.…”
