EDIBLE insects could be a solution to avoiding a global food crisis if consumers can overcome barriers such as the “ick factor”, a new study has found.
Insects are an environmentally sustainable food source, with a significantly lower carbon footprint compared to meat production, the report published in the Comprehensive Reviews in Food Science and Food Safety journal revealed.
But attitudes towards eating insects and current farming techniques and technologies need to change if edible insects are to become a common food source, researchers from the University of Leeds and the University of Veracruz, in Mexico, said.
The report found that edible insect cultivation remains rare in Western countries, where eating insects is still considered unusual, while negative perceptions have taken root in some countries where insects have been eaten traditionally, with the younger population associating it with poverty.
The best way of normalising edible insects is to target the preferences of the younger generation, who showed interest in using edible insects in unrecognisable forms, such as in flour or powder used in cookies or energy drinks, the authors said. Serving them between snacks was also effective.
The study, Edible Insects Processing: Traditional and Innovative Technologies, was carried out as worldwide food security faces serious risks, including the rapidly changing climate and an expanding global population.
Dr Guiomar Melgar-Lalanne, study author from the University of Veracruz, added: “The ‘foodies boom’ and the rise of veganism and flexitarians have opened the door to alternative food sources.
“But if edible insects are to become a common food source, current farming techniques and technologies could struggle with the demand and need to be expanded.”
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
