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.

UFS takes the lead in solar heating in the Free State

The University of the Free State (UFS) took a further step in reducing its carbon footprint and its dependency on coal fired electricity with the installation of a solar heating system at one of its residences. The contractor handed the system over to the UFS on Wednesday, 2 June 2010.

The system installed at the Vergeet-my-nie Residence is the first commercial solar water heating project in both Bloemfontein and at the UFS. It is estimated that it will provide in 70% of the residence’s energy needs and save approximately R101 000 per annum in electricity cost. The project was completed at a cost of R2,4 million.

More residences at the UFS will be refurbished with solar systems as the existing heating systems in the rest of the twenty residences are due for replacement.

The energy crisis of 2008, and the challenges and necessity to reduce the use of electricity, sparked the initiative around the installation of solar heating systems at the UFS. The UFS is the second largest energy user in Bloemfontein.

Mr Nico Janse van Rensburg, Manager: Physical Planning at the UFS, says the management of the UFS saw an opportunity in the crisis and pro-actively embarked to become a market leader. Solar heating would not only alleviate the electricity problem of South Africa, but will impact the ever increasing electricity bill of the UFS.

“Protecting the environment and being on the cutting edge of technology are core issues to the UFS,” says Janse van Rensburg. “We are an educational institution and take pride in practicing what we preach.”
