  • Nutritional composition of farmed insects [Elektronski vir] : impact of species, developmental stage, and sex
    Vehar, Anja, kemija ...
    In this study, seven insect species, Schistocerca gregaria (desert locust), Locusta migratoria (migratory locust), Tenebrio molitor (yellow mealworm), Acheta domesticus (house cricket), Gryllus ... assimilis (Jamaican field cricket), Alphitobius diaperinus (lesser mealworm) and Blaberus discoidalis (discoid cockroach), differing in sex and developmental stage, were analysed for fatty acid, amino acid, elemental and polyphenolic composition. Results confirm that the studied insects are a good source of fatty (polyunsaturated/saturated fatty acids ratio: <1.3±0.0) and amino acids (total essential amino acids <25.6±1.0 g/100 g dry weight) and elements. Although as many as 59 individual polyphenols were detected at low levels, each species contained 8–34 polyphenols. The total polyphenols content ranged from 7.6–511 mg/kg dry weight, with female desert locust (511 mg/kg dry weight, 19), adult migratory locust (288 mg/kg dry weight, 34) and discoid cockroach, both male (449 mg/kg dry weight, 21) and female (357 mg/kg dry weight, 20) having the largest amount and number of polyphenols. Results showed that species, developmental stage and sex significantly influence the biochemical parameters of the insects. The research findings will contribute to optimising insect rearing, improving the quality of insect biomass as a nutritional source and furthering their integration as food and feed.
