High-efficiency degreasing method for silkworm pupae

The invention discloses a high-efficiency degreasing method for silkworm pupae, and the high-efficiency degreasing method comprises hydraulic cold pressing, spiral cold pressing and supercritical CO2extraction for high-efficiency degreasing. The beneficial effects are as follows: the production process is simple, the degree of automation is high, and the silkworm pupae can be quickly decolorized,deodorized and degreased. By use of the supercritical CO2 extraction for high-efficiency degreasing, the structure and biological activity of proteins in the silkworm pupae can be maintained, proteinsolubility is improved, unsaturated fatty acids are retained, and nutritional value is high. The obtained silkworm pupae has beautiful milky white color and has no obvious fishy odor, and the high-efficiency degreasing method can be used for extracting the proteins of the silkworm pupae or extracting other active substances. 本发明公开了种蚕蛹的高效脱脂方法，先通过液压冷榨、螺旋冷榨和超临界CO萃取高效脱脂。有益效果为：生产工艺简单，自动化程度高，可快速对蚕蛹进行脱色脱臭和脱脂。采用超临界CO萃取法脱脂，不仅保持了蚕蛹中
