[Display omitted] •Microwave as an intensification tool for oil extraction from custard apple seeds by three phase partitioning (TPP).•Process parameters like salt concentration, slurry ratio, t-butanol to slurry ratio, power and time were optimized.•The yield of oil was improved by 1.13-fold in MPTPP than the conventional method.•The process time was reduced by 2.5 times in MPTPP than TPP. The application of microwave was observed to be an emerging intensification tool in the field of extraction. A recent study in extraction revels the rising prospectus of the microwave as an integrated unit operation with Three Phase Partitioning (TPP). This work aims to determine the best mode of microwave application for TPP assisted extraction of oil from custard apple seeds, which has significant industrial potential as a biopesticide. A maximum oil extraction yield of 33.23 (w/w) % was obtained by opting microwave pre-treatment assisted Three Pase partitioning (MPTPP) with 120 W applied power for 60 s as optimized parameters. Parameters affecting TPP, such as salt concentration, aqueous to t-butanol ratio, and slurry to t-butanol ratio, were also optimized as 45% (w/v), 1:2 (v/v) and 1:10 respectively. Also, MPTPP was observed to extract 18.46 (w/w) % of protein along with the maximum oil extraction. In MPTPP, the yield of oil was improved by 1.13-fold than the conventional method, and the process time was reduced by 2.5 times than TPP.
