Abstract:
Objective To investigate the extracting technology of the Northeast tussah pupa oil and analyze the composition of the oil. Methods The Northeast tussah pupa were crushed and dried at 60℃. The oil was extracted from the Northeast tussah pupa powder with super critical fluid extraction technology-CO2 (SFE-CO2) at the extracting temperature as 45 ℃,pressure as 50 MPa and operating time as 6 hours according to the results of homogeneous design. The composition of the oil was detected by gas chromatography (GC).Results The extracting rate of the oil from the Northeast tussah pupa powder was 17.93% (w/w)and the percent of compositions of the oil were C15:0 fatty acid 37.03%,hexadecanoic acid 5.63%,C17:0 fatty acid 32.81%,octadecanoic acid 1.79%,leic acid 3.75%,octadecadienoic acid 11.98% and α-1inoleic acid 7.00%. Conclusion The technology of SFE-CO2 can be used in extraction of Northeast tussah pupa with High extraction efficiency.
