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.

From music to theology: Stats Unit valuable in research process

Whether it is analysing data on church attendance, climate change in the Northern Cape or injuries among elite female hockey players, the Statistical Consultation Unit at the University of the Free State (UFS) can assist researchers from the planning of research to publication therof.

Many students and researchers think that the time to consult a statistician is after their research data has been collected. According to Prof Robert Schall, head of the unit, the most significant contribution a statistician can make to a research project is often during its planning. Preferably all researchers should consult the unit early in the research process.

Statistical consultation service free for postgraduates

The consultation unit, established in 2014 in the Department of Mathematical Statistics and Actuarial Science, provides support to all UFS researchers. This service is rendered to postgraduate students at no charge.

“The unit can make a contribution throughout the research process, from the planning of the research project, through the analysis of research data, up to the publication of the findings. I have been involved in projects where, for example, a few very simple changes to the design of a questionnaire would have saved the researcher and the statistician a lot of trouble. It will be beneficial for researchers to have their questionnaires and study proposals (where relevant), reviewed by a statistician,” Prof Schall said.

Fascinating research topics deliver fascinating data
The professor assisted in a study for the Department of Soil, Crop and Climate Sciences to determine whether rainfall in the Northern Cape had changed over the past 90 years, potentially indicating climate change.

Other interesting projects he has worked on came from the Department of Exercise and Sport Sciences. “Who will not be fascinated by data sets on aspects of rugby, cricket or even netball? One significant finding was a predictor of injury in elite female hockey players. The PhD student identified a pre-season test which predicted the occurrence of an in-season injury with 100% specificity and 100% sensitivity. The finding was quite surprising, and, if the results can be replicated, obviously would be useful in the prevention of injuries,” he said.

This is, of course, not an exhaustive list of projects the unit has worked on. “Not in my wildest dreams would I have expected to be involved in projects coming from the Faculty of Theology, or from the Odeion School of Music,” Prof Schall said.
