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.

Work clouds and rhizomatic learning – Prof Johannes Cronjé teaches through technology in inaugural lecture
2014-09-29

Prof Johannes Cronjé 

Prof Johannes Cronjé has been appointed as visiting professor in the Faculty of Natural and Agricultural Sciences in collaboration with the Centre for Teaching and Learning. The driving force behind his appointment is to develop young and upcoming scholars in the field of online and blended learning at our university.The title of Prof Cronjé’s inaugural lecture, ‘Tablets, Painkillers or Snake Oil – a Remedy for Education?’ suggested a compelling event. Prof Cronjé did not disappoint.

“We live in a world where we carry more information in our pockets than in our entire head,” Prof Cronjé remarked. Interesting fact: an iPhone 4 has 16 million times more processing power than the Apollo 11 – the spacecraft that put the first man on the moon.

If students carry this much processing power in their hands, what should we be teaching students? Prof Cronjé asked. “I believe the answer to that is: we should be teaching them to teach themselves.”

Presenting his inaugural lecture in the same way as he would to his students, Prof Cronjé had the entire audience within minutes vigorously participating in the event.

Prof Cronjé advocates a process called rhizomatic learning. Knowledge, he explained, grows in a similar way to rhizomes’ roots – inseparably connected and seemingly without beginning or end. “Learning is a social aspect: people learn from one another.”

Making use of freely-available online applications, Prof Cronjé demonstrated the power of technology in the classroom. “My objective is to use technology to make people enthusiastic and motivated about the learning process.” Using their smartphones, tablets and laptops, the audience could effortlessly participate through connecting to each other by means of a virtual work cloud. “Knowledge is being created in the room as it happens,” Prof Cronjé explained, “motivating you to participate in this learning experience.”

“There are three things you need for group work to be successful: a mutual goal, individual responsibility and positive interdependence. Then it is real cooperative learning,” Prof Cronjé concluded.
