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.

Collaboration between UFS and Mayo Clinic to revolutionise cancer treatment

The UFS made a discovery that may have enormous implications for the treatment of diseases in humans.

Since the discovery, the UFS joined forces with the Mayo Clinic in Rochester, US, in the fight against cancer.

In this collective effort, UFS researchers would be able to assist the Mayo team to:
• see how treatment in cancer patients is progressing,
• target treatments more effectively,
• reduce dosages in order to make treatment gentler on the patient,
• track the effectiveness of the chemotherapy drugs used, and
• gain an accurate view of how the cancer is being eliminated.

Prof Lodewyk Kock, Outstanding Professor at the Department of Microbial, Biochemical and Food Biotechnology, and his team incidentally created a technique to use argon gas particles for the first time on biological material to slice open cells to look inside.

The team that supported Prof Kock includes Dr Chantel Swart, Khumisho Dithebe (PhD student), Prof Hendrik Swart (Department of Physics) and Prof Pieter van Wyk (Centre for Microscopy).

Prof Debabrata Mukhopadhyay from the Mayo Clinic in Rochester, US, got to hear about this breakthrough at the UFS and a collaboration between the two institutions was established.

During a visit to the Bloemfontein Campus, Prof Mukhopadhyay explained novel techniques that make use of gold nanoparticles. These particles attach to chemotherapeutic drugs to selectively target cancer cells – dramatically decreasing the side effects to normal human cells.

For these new drugs (coupled to gold nanoparticles) to be accepted into clinical practice, visual and chemical proof is needed, though. This is where the technique developed by the UFS will play a vital role.

With the technique to look inside cells, the composition, location and metabolism of these drugs can be determined. This will aid in a proof of concept for the application of the nano-drugs. Furthermore, it will enable approval for use of these drugs in clinical trials and eventually could revolutionise cancer treatment as a whole.
