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.

Renewable energy systems an economical investment for the UFS

Renewable energy systems are said to be very expensive to implement initially, but in the long run they provide high economic returns.

With their decision to install renewable energy, the University of the Free State Department of Facilities Planning has now also adopted this innovative technology. They have chosen less capital-intensive solar power-generating options to generate electricity in various buildings and parking areas on all three UFS campuses.

“As per the UFS Energy Management Policy, all designs incorporate efficient, renewable energy sources varying from LED lights to solar power,” says Anton Calitz, Electrical Engineer in University Estates’ Department of Facilities Management.

South Campus taking the lead in renewable energy usage
In December 2016, a total of 26 solar-driven LED street-light poles were installed at the recently built Legae Residence’s parking area and the perimeter security area on the South Campus. This low-maintenance system improves security after dark and is independent of the national power supply, which is an important advantage during power outages. With no requirements for major earthworks and cable setting, operational costs are reduced.

The recently built infrastructure also takes pride in being the first to have a greywater system installed.  This system will also be installed at three other residences on the Bloemfontein Campus in 2017. Greywater is made up of bath, shower, and bathroom sink water. The water is reused for toilet flushing, as well as for irrigation purposes.

Various UFS electrical operations to depend on solar power
On the Bloemfontein and Qwaqwa Campuses, the computer laboratories as well as the Thakaneng Bridge Student Centre and the projected Afromontane Research Centre will be equipped with freestanding roof solar solutions during 2017. These systems are designed to operate independently of the power grid (Eskom).

The systems only operate during sunlight hours when the PV solar panels are heated by the sun, making them suitable for operations such as ventilation fans, water pumps, and small circulation pumps for solar thermal water-heating systems.
