Embodiment 1

[0014] A method for extracting tussah moth oil, the method comprising the following steps:

[0015] A. Pretreatment of tussah moths: collect the female tussah moths and male tussah moths separately and remove their wings, then take out the eggs in the female tussah moths, mix the remaining parts of the female tussah moths with the collected male tussah moths evenly , dried at 50°C, and then crushed through a 60-mesh sieve to obtain powder;

[0016] B. Crude extraction of tussah moth oil: the powder obtained in step A is extracted with carbon dioxide supercritical extraction to obtain the crude extract of tussah moth oil, and then the crude extract of tussah moth oil is concentrated to 0.3 times the original volume to obtain tussah moth oil Extract the concentrated solution; wherein, the extraction pressure is 18 MPa, the extraction temperature is 47°C, and the extraction time is 5.5h;

[0017] C. Refining of the tussah moth oil crude extract: add the tussah moth oil crude ext...

Abstract

The invention discloses an extraction method of antheraea perny oil. The method comprises the following steps: firstly, male and female antheraea perny is crushed into a powder; then, crude extraction of antheraea perny oil is carried out by supercritical CO2 extraction; and finally, a crude extract is refined to obtain antheraea perny oil. According to the invention, male antheraea perny which are previously thrown away as waste residue and residual female antheraea perny part without ovum are utilized fully and effectively. Thus, economic value in use of antheraea perny is increased, waste is avoided, and the environment will not be polluted.

Description

technical field [0001] The invention belongs to the technical field of extracting effective components from tussah moths, and in particular relates to a method for extracting tussah moth oil. Background technique [0002] Tussah silkworm, belonging to the genus Tussah silkworm of the family Lepidoptera Sagittaridae, was called spring silkworm and oak silkworm in ancient times. It got its name because it likes to eat oak leaves. It can spin silk and make cocoons, and its cocoons can be reeled. It is mainly used for weaving tussah silk. [0003] At present, people mainly utilize the cocoons of tussah silkworms to make silk or utilize the ovum of tussah moths as host eggs for breeding Trichogramma. However, only female tussah moths have eggs, and male tussah moths have no eggs, and are generally thrown away as waste; while eggs in female tussah moths only account for about 30% to 40% of the fresh weight of female tussah moths. After the eggs are taken away, the rest are also t...
