  • How does Mae promote the release of oil from silkworm pupae?
  • Oil by MAE exhibits superior physicochemical properties and antioxidant activities. SEM shows that MAE promotes the release of oil by breaking down the cell structure. Microwave-assisted extraction (MAE) of oil from silkworm pupae was firstly performed in the present research.‌
  • Is microwave technique effective for silkworm pupal oil extraction?
  • Scanning electron microscopy revealed that microwave technique efficiently promoted the release of oil by breaking down the cell structure of silkworm pupae. Therefore, MAE can be an effective method for the silkworm pupal oil extraction. 1. Introduction Silkworms are well known as an efficient large-scale producer of silk thread.‌
  • How to extract silkworm pupal oil?
  • So far the extraction of silkworm pupal oil is mainly performed by traditional methods, including mechanical pressing extraction, organic solvent extraction, aqueous enzymatic extraction and supercritical fluid extraction developed lately (Jia et al., 2014, Kotake-Nara et al., 2002, Wei et al., 2009, Zhu, 2012 ).‌
  • Does silkworm pupal oil have antioxidant activity?
  • Antioxidant activity evaluation The antioxidant activity of silkworm pupal oil was assessed using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging assay and β-carotene bleaching test. The DPPH free radical scavenging activity of oil was examined adopting the methods reported by Zhang et al. (2010).‌
  • Does silkworm pupal oil contain oleic acid?
  • Kotake-Nara et al. (2002) reported higher oleic acid (18:1) contents in Japan silkworm pupae. The results from Shanker et al. (2006) showed different proportions of fatty acids present in silkworm pupal oil from India. This may be due to different species origin, season and geographical regions. Table 3.‌
  • Does microwave treatment increase TP in silkworm pupae?
  • The increase of TP in MAE (relative to those in SE) may be attributed to the microwave treatment. The rupture of silkworm pupae cell by microwave treatment may be beneficial to the release of greater amounts of phenolics into oils in short time (Desai, Parikh, & Parikh, 2010).
