Singer, writer, and motivational speaker, Melissa de Aveiro, says: “One can only rise from the ashes when the fire starts again, and the beauty of it all is that the ashes is stuck to your clothes. As you move on, you build off it as it falls from your clothes.”

She said: “When the fire starts in you, nothing is going to stop it.”

This she said at the Division of Organisational Development and Employee Well-being’s Rising from the Ashes event held at the Centenary Complex on the Bloemfontein Campus. Melissa’s story is about never giving up and “never backing down – even when people throw you with rocks, use the rocks to build a new road”.

Melissa said: “Many people unfortunately do not rise from the ashes because there is no support from friends, people. You can never do it alone as the journey through the ashes is lonely.”

Melissa believes to get through the ashes, one has to go back and “remind yourself of when it was good in your life, remind yourself about the positive things – even though things might not be great now”.

Known as the 'Weskus Dutchess', and growing up in Vredendal, Western Cape, Melissa’s tough life, sexual abuse, drug abuse, homelessness, and the death of her son never stopped her from dreaming. All the setbacks planted in her a “passion for a guitar and people, a birth of a new season, a desire to change the world”.

To rise from the ashes, Melissa said, “You need to go back to the place where you were hurting, confront the demons, the people that abused you, maybe forgive them and remove the chains you are tied with.”

Susan van Jaarsveld, Senior Director: Human Resources at the University of the Free State, believes that hosting wellness events is a way for the UFS to show that “employees are the most valuable asset of the university and need to be looked after”.

Susan said: “Staff need to know that it is okay not to be okay. However, the UFS has systems to look after your well-being. People need to know that they are not alone, they can make use of the Department of Human Resources’ Careways Employee Wellness Programme.”

Susan believes it was important to host the event, as “staff need face-to-face interaction for their well-being, it helps people to know they are not alone”.

Melissa, the author of the book Weskus Wonderwerk, believes in being unstoppable. She said: “To rise from the trenches, always think positive about yourself, you must exist. You cannot give up; your worth cannot be determined by an individual.”

From wheat protein to perfect pizza

Barend Wentzel, an alumnus of the University of the Free State’s Department of Plant Sciences, is passionate about plant breeding. 

He literally eats and lives wheat proteins. In 1989 he initiated a breeding programme on arum lilies. “This breeding programme is at an advanced stage,” he said. Besides reading, playing the piano and accordion, Barend, due to the nature of his research at the Agricultural Research Council, also experiments with different types of ciabatta recipes made from sour dough. “I usually make my own pizza on Saturday evenings,” he said.

He is working at the Agricultural Research Council – Small Grain (ARC-SG) at the Wheat Quality Laboratory where he established a Cereal Chemistry Laboratory.

Complexity of flour quality

He explains that the focus of his research is on wheat protein composition. “The research conducted for my PhD study explains the complexity of flour quality to a certain extent, and it further emphasises the influence of the environment and genetic composition on selected baking characteristics. 

“Wheat protein can be divided into different types of protein fractions. These protein fractions contribute differently to dough properties and baking quality and the expression is affected by different components in the environment, including locality, rainfall and temperature. 

“Protein content alone does, however, not explain the variation in baking quality parameters, such as mixing time, dough strength and extensibility, and loaf volume.

“Several methods can be applied to quantify the different protein fractions. I am using high-performance liquid-chromatography (HPLC). The procedure entails the separation of a wheat protein extract through a column with chromatographic packing material. The injected sample is pumped through the column (known as the stationary phase) with a solvent (known as the mobile phase). The specific procedure, size-exclusion high-performance liquid-chromatography (SE-HPLC), is also used by the university’s Department of Plant Breeding, as well as in several international Cereal Chemistry Laboratories,” said Barend.

Dough strength and to loaf volume
“One of the highlights from the study was the positive contribution of the albumin and globulin protein fractions to dough strength and to loaf volume. The findings were wheat cultivar specific and the growing environment influenced the expression. The contribution of these protein fractions was much larger than previously reported for South African wheat cultivars,” said Barend. 
“Previous reports indicated that these protein fractions had a non-specific contribution to the gluten network during dough formation. The findings from this PhD justify further research on albumins and globulin proteins.” 

The Cereal Chemistry Laboratory at ARC-SG is involved in postgraduate student training under Barend’s guidance. He serves as co-promoter for several MSc and PhD students. He is also a collaborator on an international project with the International Maize and Wheat Improvement Centre (CIMMYT) in Mexico. Barend is furthermore working on improving wheat quality for processing and health purposes as a member of the expert working group of the International Wheat Initiative.
