Zusammenfassung:Edible insects represent a viable option to address the current need for nutritious, safe, and eco-friendly foods. People native to the Amazon region have a long-standing tradition of consuming edible insects that are relatively unknown elsewhere. This research aimed to characterize the chemical, nutritional, and microbiological composition of the edible larva of the palm weevil Rhynchophorus palmarum L. (chontacuro) from the Amazonian lowlands of Ecuador. The larvae proved to be rich in lipids (∼50 %), proteins (∼20 %), fiber (∼6 %), and oleic acid, one of their predominant fatty acids along with palmitic acid. The larvae are also rich in vitamins (B6, B9, A, and E) and are a source of β-carotene, calcium, potassium, magnesium, and phosphorus. No evidence of toxic elements (metals) or pathogenic microorganisms was observed. In general, chontacuro larvae proved to be a safe and nutritious food, managing to fully or partially cover several of the Dietary Reference Intakes for several nutrients. [Display omitted] •Chontacuro larvae are rich in lipids, proteins, and fiber.•Chontacuro larvae are an important source of oleic acid.•The larvae are rich in vitamins B6, B9, A, and E and are a source of β-carotene.•The larvae are a source of calcium, potassium, magnesium, phosphorus, and sulfur.•The larvae do not appear to be a source of toxic elements or pathogenic microorganisms.
