Our meals provide is turning into more and more fragile because the world offers with international local weather change. In consequence, meals producers are consistently looking for new sources of protein, akin to vegan meat substitutes and meat grown solely from vegetation.
One such various is bugs. Bugs have been consumed for millenia by many cultures indigenous to Africa, Asia, Latin America, and Oceania and provide a wealthy supply of protein that’s simply farmed and consumes far fewer sources to boost.
Producers are experimenting with methods to make insect-based merchandise extra palatable to western tradition, akin to by grinding crickets into flour and incorporating them into conventional meals. However the follow comes with risks for the meals allergy group.
Right here follows analysis from James Cook dinner College warning that meals containing insect-based elements might pose a hazard to folks with crustacean shellfish allergy.
James Cook dinner College researchers say meals derived from crickets and flies may cause allergic reactions in folks with present shellfish allergy – and this isn’t persistently picked up by at the moment accessible testing strategies.
Professor Andreas Lopata and Dr Shay Karnaneedi from JCU’s Australian Institute of Tropical Well being and Drugs mentioned edible insect proteins are more and more manufactured for consumption by folks and pets as a sustainable option to feed the world’s rising inhabitants.
Professor Lopata, staff chief and head of the Molecular Allergy Analysis Laboratory, mentioned bugs are extremely nutritious resulting from their excessive protein content material and consuming them can also be good for the planet, supporting Australia’s round economic system and decarbonisation approaches.
“The difficulty is that bugs are carefully associated to crustaceans akin to prawns, crabs, and lobsters. Crustacean meals allergy impacts as much as 4% of the inhabitants, with these folks at vital threat of affected by an allergic response after consuming insect protein-based meals,” mentioned Professor Lopata.
The staff studied seven cricket and two black soldier fly-based meals merchandise for his or her protein content material and potential to set off allergic reactions. Two business meals allergen take a look at kits had been analysed for his or her potential to safeguard customers.
“We recognized proteins (allergens) in insect-based meals that may trigger allergic reactions in folks with shellfish allergy. However we discovered business crustacean allergen take a look at kits didn’t reliably point out this,” mentioned Dr Karnaneedi.
“It means meals allergen take a look at kits and meals allergen labelling should take into consideration these distinctive allergens in edible bugs, particularly as this may possible be a major supply of meals protein for the rising human inhabitants,” mentioned Dr Karnaneedi.
“And shellfish allergy victims should concentrate on potential dangers posed by insect-based meals.”
The staff additionally used superior mass spectrometry strategies to characterise the proteins, and even that raised challenges.
“Our examine demonstrated that the way you selected to extract the insect proteins impacted the identification of allergens inside totally different insect species,” mentioned Professor Michelle Colgrave of CSIRO and Edith Cowan College.
“Extra analysis to standardise detection is required,” she mentioned.
The JCU staff revealed its examine along with collaborators on the Australian Nationwide Measurement Institute (NMI), Australia’s nationwide science company (CSIRO), Edith Cowan College (ECU), Singapore’s Company for Science, Expertise and Analysis (A*STAR), and Dr Thimo Ruethers from JCU’s Tropical Futures Institute (TFI) in Singapore, the place 16 totally different insect species had been not too long ago authorized for human consumption:

Lopata, The Allergen Profile of Two Edible Insect Species—Acheta domesticus and Hermetia illucens. Molecular Vitamin & Meals Analysis 2024, 2300811.
