“…Most of the species of palm weevil have already been studied. Among the various species, the following had been profiled: African palm weevil R. phoenicis in Cameroon (Fogang Mba et al 2017;Womeni et al 2009Womeni et al , 2012, Nigeria (Adeyeye 2017;Edijala et al 2009;Ekpo and Onigbinde 2005;Elemo et al 2011;Ogbuagu et al 2011;Okunowo et al 2017;Omotoso and Adedire 2007) and Ghana (Atuahene et al 2017;Laar et al 2017); R. palmarum in Côte d'Ivoire (Dué et al 2009;Gbogouri et al 2013) and Nigeria (Adeyeye 2017), and R. ferrugineus in Egypt (Abdel-Moniem et al 2017) and Malaysia (Ali et al 2006). However, based on the review of available scientific literature, no nutritional information can be found for the species R. bilineatus.…”

The sago grub (Rhynchophorus bilineatus) [Montrouzier, Coleoptera, Dryophthoridae] is a local delicacy in the Papua Province in Indonesia. In this study, the nutrient content of the edible insect was measured using chromatographic and spectrometric methods. The results showed that it contains 10.39 g protein and 17.17 g oil/ 100 g fresh weight. The sago grub meets the FAO/ WHO requirements of 40% essential amino acids and a 0.60 ratio between essential to non-essential amino acids. Its limiting amino acid is methionine + cysteine. The major fatty acids found in the sago grub are palmitic (42%), oleic (45%), and linoleic (3%) acids. Although vitamin E is exclusively produced by photosynthetic organisms, a gram of sago grub oil contains 51 μg vitamin E, which is composed mainly of tocopherols (92%). In contrast with palm oil, the sago grub oil contains δ-tocopherol (0.12 μg/g oil), and a significantly high amount of β-tocopherol (3.85 μg/g oil). It is a source of zinc and magnesium and contains safe levels of heavy metals. Based on these nutritional properties, the Indonesian sago grub can be considered as a good source of nutrients, and its propagation and utilization should be encouraged especially in other areas of Indonesia and maybe in neighboring countries where they are also endemic, and where malnutrition is prevalent. The consumption of edible insects should be considered as a component of dietary diversificationa sustainable way of alleviating the nutritional status of the population.

“…Water and ash contents of insect flours were assayed using the method of the Association of the Official Analytical Chemists (AOAC, 1996) and calculated as described previously (Fogang Mba et al, 2017). Protein content was determined by multiplying total nitrogen content with nitrogen to protein conversion factor, previously determined.…”

“…Protein content was determined by multiplying total nitrogen content with nitrogen to protein conversion factor, previously determined. Total lipidswere extracted from the raw thawed, eviscerated and ground insects according to Folch et al (1957) with slight modifications as previously described (Fogang Mba et al, 2017). Water, ash, nitrogen and lipid contents were analysed at least in triplicate.…”

“…Approximately 5 μg of neutral lipid and polar lipid fractions in 10 μL chloroform were analysed by high-performance liquid chromatography (HPLC) with a modular UltiMate 3000 RS system (Dionex, Voisins Le Bretonneux, France) equipped with an UptisphereStrategy column (150 mm × 4.6 mm, 2.2 μm, 100 Å; Interchim, Montluçon, France) and coupled to an evaporative light scattering detector (ELSD) Sedex 85(Sedere S.A., Alfortville, France). Chromatographic conditions, identification and quantification of neutral lipids and phospholipids were described previously (Fogang Mba et al, 2017). Lipid classes were identified bycomparison of their retention times to those of lipid standards and theirconcentrations calculated by the use of calibration curves (range concentrations)obtained witheach standard.…”

Chromatographic conditions for fatty acid separation and their identification were performed as described previously (Fogang Mba et al, 2017. Individual fatty acids were identified by comparison of their retention times with those of standards (FAMEmix; Supelco, SigmaSaint Quentin Fallavier, France).Any loss of the separation capacity of the column was controlled on the chromatograms obtained with the fatty acid standards.…”

The objective of this study was to assess the antioxidant activities of three plant extracts (Moringa oleifera leaves, Xylopia aethiopica fruits, and Allium cepa leaves) and to evaluate their effects on the preservation of fish polyunsaturated fatty acids (PUFAs) during smoking and sun‐drying processes. PUFAs are highly prone to oxidation during fish processing. The plant extracts were analyzed for their polyphenol contents and were evaluated for their total antiradical capacity. The polyphenol components of each plant were characterized. The hydroethanolic and aqueous extracts were added to the fish at concentrations of 3, 6, 9, and 12 g/L and 10, 20, 30, and 40 g/L, respectively. Butylated hydroxytoluene (BHT) was used as a positive control at a concentration of 2 g/L to compare the antioxidant effects of the plant extracts. The treated fish was subjected to smoking or sun drying and the fatty acid composition of the fish lipid extract was assessed. The results showed that the total polyphenolic, flavonoid, and tannin contents varied significantly from one plant extract to the other (p < .05). The radical scavenging and FRAP increased significantly with the concentration of the plant extracts (p < .05). An HPLC analysis of the extracts led to the preliminary identification of four hydroxycinnamic acids in M. oleifera and X. aethiopica, one anthocyanin and one flavone glycoside in M. oleifera, and four flavan‐3‐ols in X. aethiopica. Moreover, eight flavonols were preliminarily identified in the three plants. Compared to the control product, these plant extracts significantly protected fish PUFAs from oxidation (p < .05). The aqueous extract of A. cepa at 40 g/L better preserved omega‐3 in fish during smoking and sun drying than the control product. Incorporating the three plant extracts during smoking and sun‐drying processes can effectively preserve the PUFAs in fish. Therefore, these plants are viable sources of natural antioxidants in the preservation of fish products.
