### Fatty Acid Profile  
The fatty acid (FA) profile of SGP is shown in Table 1, expressed as % of total FA and g FA per 100 g DW SGP. Among the saturated fatty acids (SFA) found in SGP, the most abundant were palmitic acid (16:0) (42.5% of total FA), followed by myristic acid (14:0) (2.39% of total FA), and stearic acid (18:0) (1.30% of total FA). A similar palmitic acid content (42.45% of total FA) has been reported for _R. bilineatus_ (sago grub) [8]. A lower palmitic acid content has been reported in large nymphs of _Blaberus cranifer_ (30.9% of total FA) [17], _T. molitor_ (19.0% of total FA) [18], and large Huhu grubs (23.0% of total FA) [14]. [PERSON], et al. [19] reported that the diet of sago grubs can have a substantial effect on the fatty acid composition. While the myristic acid content of _T. molitor_ larvae fat (5.0% of total FA) [18] is reported to be higher than that of SGP (2.39% of total FA), that of _R. bilineatus_ (0.81% of total FA) [8] and large nymph (_Blaberus craniffer_) (1.7% of total FA) [17] are lower than SGP (Table 1). Steric acid, the third most abundant SFA in SGP, was found to be at a level 10 times higher than lauric acid. This amount of stearic acid in sago grubs is lower than that found in wild-harvested Huhu grubs [14]. The WHO (World Health Organization) has recommended reduced consumption of SFA due to their association with increased incidence of heart disease and elevated low-density lipoprotein-cholesterol (LDL-C) [20]. A potential health benefit of consuming SGP was assumed due to the low levels of lauric acid and myristic acid (0.90 and 2.39% of total FA, respectively, see Table 1), which are reported to promote hypercholesterolemia when present at high levels [20]. Palmitoleic acid (16:1 _cu_7) (12.1% of total FA) and oleic acid (18:1 _cu_9) (39.0% of total FA) were the most prominent monounsaturated fatty acids (MUFA) available in SGP (Table 1). The total MUFA was higher (51.2% of total FA) than the SFA and PUFA content of SGP (Table 1), and was higher than that reported for _R. bilineatus_ (47.6% of total FA) [8], _R. ferrugineus_ (36.53% of total FA) [19], _Blaberus craniffer_ (50.9% of total FA) [17], and _Apis mellifera_ pupae (48.9% of total FA) [21]. However, the MUFA in SGP was lower than in Huhu grubs (71.5%of total FA) [14]. The FA content of the palm trunk eaten by sago grubs contains 46.8% oleic acid, and ingestion of this material likely contributes to the reported profile [8]. The MUFA content is primarily composed of _cis_-oleic acid and _cis_-palmitoleic acid. Oleic acid is commonly found in edible insect material and is reported to help reduce blood pressure and the development of immune, inflammatory, and cardiovascular diseases on consumption by humans [22]. In contrast to SGP (Table 1), _R. bilineatus_ contained eicosenoic acid (20:1) and low levels of palmitoleic acid [8]. These findings could be due to species effects and differences in the analytical method or pre-processing treatment prior to the export of the samples used in our study. In the present study, SGP was found to have low levels of polyunsaturated fatty acid (PUFA) (1.49 % of total FA), compared with _R. bilineatus_ (4.57 % of total FA). SGP (Table 1) contained linoleic acid (18:2 cuo-6) (1.02% of total FA), which is one of the main components of PUFA in edible insects and has been shown to confer anti-inflammatory properties on consumption [23]. SGP contained higher levels of MUFA (51.2% of total FA) than SFA (47.3% of total FA) and PUFA (1.49% of total FA). A similar trend was observed by [PERSON] and [PERSON] [7] for _R. phoneicis_ (MUFA, 43.4; SFA, 38.9; PUFA, 17.7% of total FA). However, SGP was found to contain high levels of SFA and MUFA and low levels of PUFA compared to the larvae of _R. phoneicis_ and _R. palmarus_ from Nigeria, with SFA ranging from 29-31% of total FA, MUFA from 37-40% of total FA and PUFA ranging from 29-34% of total FA [7; 24]. Usually, insects contain higher unsaturated fatty acid (UFA) than SFA [25].
