Chitin and chitosan were extracted from all specimens of Type I and II two-spotted field crickets (Gryllus bimaculatus) following chemical treatment with an acid and alkali. For chitin extraction, 2 N HCl and 1.25 N NaOH solutions were used to achieve demineralization and deproteinization, respectively. For chitosan extraction, 50 % NaOH (w/v) and 50 % NaOH (w/w) solutions were used to achieve deacetylation. Chitosan yielded from adult exoskeletons of G. bimaculatus in Test A of Type I was 1.76 and 8.40 % on a fresh weight (FW) and dry weight (DW) basis, respectively, after treatment with 50 % NaOH (w/v) at 95°C for 3 h. Furthermore, the chitosan yielded in Test D of Type II was 1.79 and 7.06 % on FW and DW basis, respectively, after treatment with 50 % NaOH (w/w) at 105°C for 3 h. The average yield of chitin and chitosan was 2.42 and 1.65 % on a FW basis, and 10.91 and 7.50 % on DW basis, respectively. The deacetylation (%) of chitosan extracted from adult exoskeletons in Tests A, B, C1, C2, D1, and D2 were 81.2 %, 14.5 %, 19.6 %, 90.7 %, 17.1 %, and 95.5 %, respectively. The viscosities of the chitosans extracted from adult exoskeletons in Tests A, C2, and D2 were 32.0, 21.6, and 62.4 cP (centi Poise), respectively. The molecular weight of chitosan from adult exoskeletons of G. bimaculatus was 308.3 kDa. Our results indicate that adult exoskeletons of G. bimaculatus could be used as a source of chitin and chitosan for use as functional additives in industrial animal feeds.

“…The results were in line with the previous study by Kim et al, which reported that the content of USFAs (60.74 ± 0.4 to 63.55 ± 0.56% w/w) was double that of SFAs (29.19 ± 0.79 to 31.88 ± 0.56% w/w) in G. bimaculatus powder from various processing conditions, including lyophilization process, hot-air process at 90 °C for 7 h, roasting process at 160 °C for 40 min, and frying process at 180 °C for 30 sec. 31 However, the results differed from the previous study by Udomsil et al, which reported that the ratio of SFAs: MUFAs: PUFAs was 12.76: 9.85: 1.80 in G. bimaculatus powder from an air-dried process at 60 °C for 48 h. 8 …”

Purpose This study aimed to extract the oil from Gryllus bimaculatus de Geer, evaluate its potential for cosmeceutical applications, and develop nanoemulsions to promote the cosmeceutical capabilities of the oil. Methods G. bimaculatus oil was produced by the cold pressing method. Its fatty acid compositions were assessed by fatty acid methyl ester/gas chromatographic-mass spectrometry. The antioxidant activities of the oil were investigated in terms of radical scavengers, reducing power, and lipid peroxidation inhibition. The whitening effects were investigated through anti-tyrosinase activities, whilst the anti-aging effects were investigated through inhibition against collagenase, elastase, and hyaluronidase. The irritant effects were investigated by the hen’s egg chorio-allantoic membrane test and the cytotoxicity assay in immortalized human epidermal keratinocytes and human foreskin fibroblast cells. The nanoemulsions were developed, characterized, and evaluated for their stability and cosmeceutical properties. Results G. bimaculatus oil, rich in linoleic acid (31.08 ± 0.00%), oleic acid (30.44 ± 0.01%), palmitic acid (24.80 ± 0.01%), and stearic acid (7.61 ± 0.00%), demonstrated promising cosmeceutical properties in terms of antioxidant, anti-tyrosinase, and anti-skin ageing activities. Besides, the oil was safe since it induced no irritation or cytotoxicity. G. bimaculatus oil was successfully developed into nanoemulsions, and F1, composed of 1% w/w G. bimaculatus oil, 1.12% w/w polysorbate 80, 0.88% w/w sorbitan oleate, and 97% w/w DI water, had the smallest internal droplet size (53.8 ± 0.6 nm), the narrowest polydispersity index (0.129 ± 0.010), and a pronounced zeta potential (−28.23 ± 2.32 mV). All cosmeceutical activities of the oil were significantly enhanced after incorporation in the nanoemulsions (p < 0.001), particularly the whitening effects. Conclusion G. bimaculatus oil nanoemulsion was an attractive cosmeceutical formulation with potent whitening effects, along with antioxidant and anti-aging properties. Therefore, nanoemulsion technology was found to be an effective strategy for improving the cosmeceutical properties of G. bimaculatus oil.

“…However, research on these methods as applied to insect materials is currently lacking. The storage of insect products has been studied in more detail; for example, oxidation safety during the storage of rice grasshoppers, brown grasshoppers, crickets, and white spotted flower beetles has been reported (Kim et al 2015a;Kim et al 2016;Son et al 2016), as has the quality of crickets during storage (Kim et al 2016). In addition, the quality characteristics of edible crickets have been reported according to processing conditions (Lee & Kim 2019).…”

In order to broaden the usability of the two-spotted cricket (Gryllus bimaculatus De Geer) as a food ingredient, we investigated the effects of freeze-drying and hot airdrying, as well as the effects of storage at various temperatures (4-40°C), on the quality of cricket powder during short-term storage. We found that the water absorption index values of freeze-dried and hot air-dried powder were 3.6 and 3.0 g/g, respectively, while the pH and color values of the powders were similar for the two drying methods. During storage at various temperatures over 14 days, water absorption and pH remained similar regardless of the drying method and storage temperature. However, freeze-dried powder showed more color change compared to air-dried powder according to their chroma values. In total bacteria and Escherichia coli detection tests, Escherichia coli was not detected under all storage conditions, whereas total bacteria were observed (~4 Log CFU/g) only in freeze-dried powder stored for 14 days at 40°C. Therefore, our results suggest that the quality characteristics of two-spotted cricket powder can be affected by the drying method applied, but these powders can be maintained for 14 days, largely without changes, at storage temperatures up to 40°C.
