Silkworm pupae have high monounsaturated and polyunsaturated fatty acid contents and low saturated fat content (Payne et al., 2016). About 70%–80% of the fatty acid content of silkworm pupae is unsaturated, while about 1% is unsaponifiable matter in oil, including campesterol, β‐sitosterol, and cholesterol.
