“…The percentage distribution of the protein bands in the aqueous extracts varied upon flour fraction used and extraction conditions applied. As already described by Bußler et al (2016), the bands observed in the range between 14 and 32 kDa could possibly originate from cuticle proteins with molecular weights predominantly between 14 and 30 kDa (Andersen et al, 1995) or chymotrypsin-like proteinase (24 kDa) (Elpidina et al, 2005), whereas the bands observed ranging from 32 to 95 kDa could possibly originate from enzymes and other proteins, e.g. melanization-inhibiting protein (43 kDa), β-glycosidase (59 kDa), trypsin-like proteinases (59 kDa), and melanization-engaging types of protein (85 kDa) (Cho et al, 1999; Ferreira et al, 2001; Prabhakar et al, 2007; Zhao et al, 2005).…”

Depending on the species, edible insects are highly nutritious and thus represent a noteworthy alternative food and feed source. The current work investigates the protein extractability and techno-functionality of insect flour fractions recovered from Tenebrio molitor and Hermetia illucens. T. molitor and H. illucens flours contained about 20% crude fat and 60% and 36 % crude protein, respectively. Defatting reduced the crude fat content to 2.8% (T. molitor) and 8.8% (H. illucens) and increased the crude protein content to 68% and 47%, respectively. To isolate proteins from the flours, protein solubility was optimized by varying the pH, the ionic strength, and the extraction temperature of the solvent. All products and by-products accumulated in the protein production process were characterized by composition, selected techno-functional properties, protein solubility, composition and structure as well as their microbial load.

“…The protein quality in terms of essential amino acid content satisfies the recommendation for adult`s requirement by the WHO [6]. First, studies on techno-functional properties of TML protein fractions revealed promising protein solubilities between 60 and 100% at alkaline pH depending on the applied pre-treatment, extraction procedure and fractions' composition [14][15][16][17].…”

protein (52.5-58.2%db) and fat (21.4-26.6%db) content. Highest protein recovery of max 72% was determined in the particle size fraction 500-1000 µm. Concluding, these results provide insights into physico-chemical characteristics of mealworms affected by pre-treatment and drying. The potential of dry fractionation techniques for protein enrichment and delivery of a variety of differently composed mealworm fractions was demonstrated and may provide an interesting potential to optimize water and energy consumption during insect fractionation.

“…To date, data on the prevalence and level of contamination of bacteria in raw larvae are few and do not enable a proper estimation of H 0 . Main data came from larvae raised in Belgium [48,50,60,[83][84][85], Italy [66,86,87], Germany [88], and the Netherlands [9,50,51,89].…”

Entomophagy has been part of human diets for a long time in a significant part of the world, but insects are considered to be a novel food everywhere else. It would appear to be a strategic alternative in the future of human diet to face the challenge of ensuring food security for a growing world population, using more environmentally sustainable production systems than those required for the rearing of other animals. Tenebrio molitor, called yellow mealworm, is one of the most interesting insect species in view of mass rearing, and can be processed into a powder that ensures a long shelf life for its use in many potential products. When considering insects as food or feed, it is necessary to guarantee their safety. Therefore, manufacturers must implement a Hazard Analysis Critical Control plan (HACCP), to limit risks for consumers’ health. The aim of this case study was to develop a HACCP plan for Tenebrio molitor larvae powders for food in a risk-based approach to support their implementation in industry. Specific purposes were to identify related significant biological hazards and to assess the efficiency of different manufacturing process steps when used as Critical Control Points. Then, combinations of four different processes with four potential uses of powders by consumers in burger, protein shake, baby porridge, and biscuits were analyzed with regard to their safety.
