Abstrakt: Insects have potential to become food ingredients, but it is necessary to improve the sensory properties of insects to help them to be better accepted by the population. The purpose of this study was to produce and characterize house fly larval meal (FLM) converted to a micro-encapsulated powder to improve appearance and other organoleptic characteristics. FLM showed high protein (54%) and lipid (22%) content, with a microbiological activity compatible for food purposes. Moreover, the high content of essentials amino acids (lysine, cysteine and leucine) and unsaturated fatty acids (oleic, linoleic and palmitoleic) make FLM a valuable nutritional source. Spray drying was selected to encapsulate FLM (0.5-2% w/v) using maltodextrin (20% w/v) and alginate (0.5% w/v). Encapsulation improved the appearance of FLM, creating a white-beige, monodispersed micro-powder (9 µm in size). Micro-powder with 2% FLM is considered a good source of protein (5.1%). Microencapsulation also dramatically reduced the volatile emissions of FLM. In conclusion, novel FLM micro-powders were developed using a simple and scalable encapsulation technique. The micro-powder with 2% FLM is a good source of protein, has a pleasant appearance similar to vegetable meals and has improved odor compared to typical insect meals. Thus, insect-based food ingredients in micro-powders could become more accepted by the general population.
