Oil portion of Tenebrio molitor (yellow mealworm) and Acheta domesticus (house cricket) were examined and it was investigated how the physicochemical properties of the oils changed with High Hydrostatic Pressure Assisted Extraction (HHP-E) and conventional solvent extraction (CE) with hexane. The effect of HHP-E at 500 MPa and 30 and 40 °C for 15 min on the properties of oils was compared with the CE. Following the extraction of oil, fatty acid composition, peroxide value, crystallization and melting points, total phenolic content and antioxidant activities were determined. Oil yield was found in the range of 22.75–24.22% for mealworm and 16.17–18.09% for cricket with significant amount of Ω-3 and Ω-6 fatty acids. Fatty acid composition of insect oils was significantly affected from HHP-E and extraction temperature (p < 0.05). The difference between crystallization and melting point of mealworm were found to be higher than cricket (p < 0.05). HHP-E insect oil had desirable characteristics to be used as a food ingredient.

高静水压（HHP）处理和温度对从家蝇（A）和黄粉虫（黄粉虫）中提取的昆虫油理化特性的影响

的油部分黄粉虫（黄粉虫）和Acheta domesticus（房）进行了研究，并研究了高静水压辅助萃取（HHP-E）和常规己烷萃取（CE）方法如何改变油的理化性质。与CE对比了HHP-E在500 MPa和30和40°C下15分钟对油的性能的影响。提取油后，测定脂肪酸组成，过氧化物值，结晶和熔点，总酚含量和抗氧化活性。含大量Ω-3和Ω-6脂肪酸的粉虫的and油产量范围为22.75–24.22％，的油品产量范围为16.17–18.09％。昆虫油的脂肪酸组成受到HHP-E和提取温度的显着影响（p <0.05）。发现粉虫的结晶度和熔点之间的差异高于（p <0.05）。HHP-E昆虫油具有用作食品成分的理想特性。
