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.

DNA sequencer launched at the UFS
2013-11-25

Dr Gansen Pillay, Deputy Chief Executive Officer of the National Research Foundation, explaining to the scholars what will be expected of them.

The University of the Free State (UFS) can now collect immensely valuable data on drug resistance in HIV/Aids and TB with the new DNA sequencer that was launched recently at the International workshop on HIV/AIDS and TB drug resistance at the Bloemfontein Campus.

The DNA sequencer will allow the Free State province to produce viral and bacterial genetic data to fight the local development of HIV/ Aids and TB drug resistance.

The HIV and TB epidemics have expanded very fast and South Africa now has the largest HIV and TB treatment programme in the world, with over 2 million patients on treatment. However, these successful treatment programmes are now being threatened by the appearance of drug resistance.

The Free State province has been at the forefront of fighting HIV drug resistance in South Africa and has one of the most advanced treatment programmes for the management of resistance strains in the country. In addition, researchers at the University of the Free State are leading partners in the Southern African Treatment and Resistance Network (SATuRN; www.bioafrica.net/saturn), a research network that has trained over 2 000 medical officers in the treatment of drug resistance strains.

The Department of Medical Microbiology and Virology in the Medical School at the UFS has partnered with the provincial department of health, the Medical Research Council (MRC) and the Delegation of the European Union to South Africa to fund a dedicated DNA sequencer machine that will be used to generate HIV and TB drug-resistance results. This new machine will enable cutting-edge research to take place, using the data in the province and, importantly, support patients with resistance strains to have access to advanced genotypic testing techniques.

“HIV drug resistance is a very serious problem in South Africa, and the recent advances in DNA testing technology allow clinicians in the province to access drug resistance testing, which enables them to manage patients appropriately who fail treatment, and use the results to cost-effectively extend and improve patients’ lives,” says Dr Cloete van Vuuren, Specialist in Infectious Diseases at the UFS’s Faculty of Health.

Dr Dominique Goedhals, pathologist from the Department of Medical Microbiology and Virology at the UFS, adds: “We have been looking forward to expanding our work with the clinicians and researchers, using DNA sequencing to shed light on the causes and consequences of drug resistance in urban and rural settings in the province.”
