摘要：Perilla seed oil riched in the ω-3 fatty acid especially α-linolenic acid, is associated with a beneficial role in human health. In the present study, Aqueous Enzymatic Extraction (AEE) of crude oil from Perilla seeds was investigated. The extraction parameters of Perilla seed oil including enzyme type, solid-to-water ratio, pH, temperature, enzyme loading and hydrolysis time were determined by Response Surface Methodology (RSM). The RSM results showed the optimum extraction enzyme for Perilla oil was plant protein hydrolysate complex enzyme. The optimized values of solid-to-water ratio, pH, temperature, enzyme loading, and hydrolysis time for extracting oil from perilla seeds respectively were 1:4, 6, 55 °C, 2% and 4.5 h. Under the conditions, the maximum oil recovery of perilla oil was 88.52%, perilla seed oil extracted by AEE possessed a high extraction yield.
