Insects on the menu
Beetle juice and bug flour; Drs Ismari van der Merwe and Cariena Bothma are researching the possibility of a high-protein diet consisting of insect ingredients.

You’ve just had a tasty milkshake made from grasshopper juice, now for a light snack. Your choice: Salty cricket cookies or a deep-fried ant delight?

One of these days the above delicatessen may just find its way to your local restaurant menu if Drs Ismari van der Merwe, Cariena Bothma, both lecturers in the Department of Consumer Science, and their enthusiastic team of students have their way. Insects as food are rich in protein, often tasty, and having them on a menu is not as far-fetched as you may think. After all, we know what culinary delights mopani worms – and yes – cooked land snails (enjoyed as escargots) have become over the years.

 

Cricket smackerals

 

When Dr Van der Mewe explains the benefits of her team’s vision for a high-protein diet consisting of insect ingredients (cricket flour as an example), one becomes aware that this could be the solution to a myriad of problems. Insects eat much less than our regular menu items such as cows (beef), sheep (lamb chops) or pigs (pork). Insects as an alternative diet will reduce the negative impact that larger animals have on the environment and greenhouse gases. Insects have faster life cycles and it takes less effort and space to breed and feed them.

“Ugh! Ick! Disgusting,” you might think. But picture the taste lab where volunteers are given regular chocolate cookies made with regular flour, and then asked to compare it with cookies made from cricket flour. Dr van der Merwe assures me that most people will be unable to distinguish between them, often even preferring the cricket smackerals.

 

Heathy alternative

 

Insect breakfast cereals, granola, and snack food is a real and viable solution for the developing world where food is scarce, and hunger is a real issue. But is it healthy? Dr Van der Merwe assures me that during the process of ‘bug to flour’, they are addressing the main concern: micro-organisms that might be detrimental to health. Once the insects or processed insect by-products arrive on your plate, it’s a healthy high-protein alternative that might become the next revolutionary diet.

So, stand aside Atkins, beware Banting, and be gone Gluten-free – there is a new diet on its way to the menu. Brace yourself for beetle juice and bug flour: a diet full of proteins, fat, energy, and essential amino acids.

Dr Elizaveta Kovaleva and Dr Matthew Huber, postdoctoral research fellows in the Department of Geology at the University of the Free State (UFS), attended the European Geosciences Union (EGU) General Assembly in Vienna, Austria in April 2017, where Dr Kovaleva was declared a winner of the EGU photo contest with a photograph entitled “Movement of the ancient sand”.

Submitting the winning photo
Each participant could submit up to three photos to participate in the contest before the conference. From all the photographs 10 were selected and displayed for the entire week at the assembly so participants could vote for their three favourite photos. At the end of the week three winners were selected. The prize winners received a free EGU book of their choice, free registration for next year’s EGU and an option to judge the photo competition next year. The photos will be printed on postcards next year, so all participants can send them wherever they want around the globe.

“The picture was taken in the Zion National Park in the US. Myself and Dr Huber were travelling around the western states, visiting national parks. The person in the picture is Dr Huber,” said Dr Kovaleva.

Dr Kovaleva was also invited to participate - as a recently published author - in a workshop, called: ”Publishing in EGU journals: Solid Earth and Earth Surface Dynamics – Meet the Editors”.

At the assembly, Dr Kovaleva attended sessions on Tectonics and Structural Geology as well as on Geochemistry, Mineralogy, Petrology and Volcanology. These sessions were especially interesting in the scope of her research and are directly related to it. “I am a metamorphic petrologist, and with my PhD, I essentially studied microstructures. At the moment, I am studying the Vredefort impact crater, which has experienced both metamorphism and deformation,” she said.

“The winning photos will be printed on postcards,
so all participants can send them wherever they
want around the globe”.

Building scientific connections
For both researchers, the assembly was an opportunity to meet former colleagues and professors from universities all over the world and shake hands with authors whose papers and work they were familiar with, but had never met in person.

“EGU is a perfect opportunity to build scientific connections and relationships, advertise your research and start new collaborations and projects,” said Dr Kovaleva.

The EGU General Assembly 2017 was a great success, with 4 849 oral, 11 312 poster, and 1 238 PICO presentations. Some 649 unique scientific sessions, together with 88 short courses and 322 side events, created an interesting programme. At the conference 14 496 scientists from 107 countries participated, of whom 53% were under the age of 35. Thirty one were from South Africa.
