Abstract
The use of processed insect proteins for poultry and pig feed has been authorized since August 2021 (Regulation EU, 2021/1372). It has been already authorized for aquaculture since 2017 (Regulation EU, 2017/893). The adoption of this Regulation has boosted the European insect industry. However, there is currently little information regarding the evaluation of the shelf-life of insect-based feeds. The present work analyzed meals of Hermetia illucens that underwent two different treatments. The first treatment involved pre-sterilization at 80 °C for 2 h, and after that the larvae were subjected to treatment at 65 °C. The second treatment consisting in a heat treatment at 65 °C without pre-sterilization. The analysis performed for specific microbiological parameters, such as presence of β-glucuronidase positive Escherichia coli, Enterobacteriaceae, colony count at 30 °C, Salmonella spp., Listeria monocytogenes, Bacillus cereus, Clostridium perfringens, coagulase-positive Staphylococcus, yeasts and moulds, did not reveal any concerns about bacteria counts or pathogen presence.
期刊介绍：
The Journal of Stored Products Research provides an international medium for the publication of both reviews and original results from laboratory and field studies on the preservation and safety of stored products, notably food stocks, covering storage-related problems from the producer through the supply chain to the consumer. Stored products are characterised by having relatively low moisture content and include raw and semi-processed foods, animal feedstuffs, and a range of other durable items, including materials such as clothing or museum artefacts.
