Abstract
Lipid compositions of five species of edible insects: adult bee, bee brood, winged termite, soldier termite and mopane worm were investigated using standard analytical methods. The saturated fatty acids (SFAs): C2:0, C3:0, C4:0 and C5:0 were absent, C6:0, C8:0 and C10:0 had 0.00%, palmitic acid (C16:0) had the highest level of abundance among the SFAs with value range of 16.6-31.9%, C18:1 (cis-9) (26.239.8%) was the most abundant monounsaturated fatty acid (MUFA) whilst C24:1 (cis-15), C18:1 (trans6) and C18:1 (trans-9) were found in trace amounts. The highest abundant polyunsaturated fatty acid (PUFA) was C18:2 (n-6) (11.9-23.0%). Levels of total saturated fatty acid (SFA) (21.7-39.9%) were less than total unsaturated fatty acid (TUFA) (60.2-78.4%). The levels of C18:2 (n-6)/C18:3 (n-3) (448-1480) were much above the recommended 5-10. Lecithin (285-349 mg/100 g) was the most abundant phospholipid followed by phosphatidyl ethanolamine (144-167 mg/100 g). The major sterol was cholesterol with values ranging from 153-269 mg/100 g.
