Research-industry linkages for the promotion of biofortified maize and wheat, highlighted the link between research and industry.

Prof Maryke Labuschagne believes that research through collaboration can be to the benefit of the whole food chain, literally from laboratory to farm to fork. 

She is professor of Plant Sciences at the University of the Free State (UFS) and heads the SARChI Chair: Disease Resistance and Quality in Field Crops.

Prof Labuschagne recently delivered a presentation at a webinar organised by the International Maize and Wheat Improvement Center (CIMMYT) and the United States Agency for International Development (USAID). The focus was on Maize: Technologies, Development and Availability in South Asia. 

Her presentation: Research-industry linkages for the promotion of biofortified maize and wheat, highlighted the link between research and industry, stating that research outcomes should improve the livelihoods and health of people who grow and consume the food. 

Prof Labuschagne believes research by universities and research organisations can be linked to industry, with special reference to the development of biofortified crops. “Biofortification is the process where crop nutritional value is improved through genetic intervention,” she explains.

She states that the same technologies for crop biofortification can be applied throughout the world. 

In her presentation, Prof Labuschagne also reviewed the current technologies used, which include conventional genetic improvement and genetic engineering. Recently, the latter has been increasingly used for crop biofortification.

Enhancing nutritional value of crops

According to Prof Labuschagne, crop biofortification has developed exponentially in the last decade. Crop biofortification has been very successful in terms of improving the iron and zinc content, the provitamin A content, and the amounts of essential amino acids (lysine and tryptophan) in various staple foods.

“What we have learned is that genetic intervention in crop nutritional value is the best long-term solution to sustainably address vitamin and micronutrient deficiencies, especially in poor communities. It is a sustainable, and relatively cheap way to address mineral and vitamin deficiencies in the diets of people,” she says.

UFS research on biofortification

For a number of years now, a team of UFS scientists in the Division of Plant Breeding has been doing research on the biofortification of maize, sweet potatoes, bananas, and cassava. “The research took place in collaboration with a number of partners in Africa, and with funding from organisations such as the Bill and Melinda Gates Foundation.”

“This research has resulted in tangible outcomes, including the availability of seed and planting material of biofortified crops for farmers, who in turn make these crops available to consumers,” says Prof Labuschagne.

The crops not only add to the well-being of consumers, especially children and women, but also contribute to food security.

UFS researchers are producing various flavour and fragrance compounds
2015-05-27

 

The minty-fresh smell after brushing your teeth, the buttery flavour on your popcorn and your vanilla-scented candles - these are mostly flavour and fragrance compounds produced synthetically in a laboratory and the result of many decades of research.

This research, in the end, is what will be important to reproduce these fragrances synthetically for use in the food and cosmetic industries.

Prof Martie Smit, Academic Head of the Department of Microbial, Biochemical and Food Biotechnology at the UFS, and her colleague Dr Dirk Opperman, currently have a team of postgraduate students working on the production of various flavour and fragrance compounds from cheap and abundantly available natural raw materials. 

Prof Smit explains that most of the flavours and fragrances that we smell every day, originally come from natural compounds produced mainly by plants.

“However, because these compounds are often produced in very low concentrations by plants, many of these compounds are today replaced with synthetically-manufactured versions. In recent times, there is an increasing negative view among consumers of such synthetic flavour and fragrance compounds.”

On the other hand, aroma chemicals produced by biotechnological methods, are defined as natural according to European Union and Food and Drug Administration (USA) legal definitions, provided that the raw materials used are of natural origin.  Additionally, the environmental impact and carbon footprint associated with biotech-produced aroma chemicals are often also smaller than those associated with synthetically-produced compounds or those extracted by traditional methods from agricultural sources.

During the last four years, the team investigated processes for rose fragrance, vanilla flavour, mint and spearmint flavours, as well as butter flavour. They are greatly encouraged by the fact that one of these processes is currently being commercialised by a small South African natural aroma chemicals company. Their research is funded by the Department of Science and Technology and the National Research Foundation through the South African Biocatalysis Initiative, the DST-NRF Centre of Excellence in Catalysis and the Technology Innovation Agency, while the UFS has also made a significant investment in this research.
