Prof Arno Hugo recently participated in a session on food with integrity during a webinar by the Integra Trust, where he presented a lecture focusing on the importance of food traceability and the information communicated to the consumer.

In the complete process between farm and fork, consumers are looking for someone to hold accountable if their animal welfare, product quality, and product safety expectations are not met.

On World Sustainable Gastronomy Day earlier this month (18 June 2020), Prof Arno Hugo from the Department of Microbial, Biochemical and Food Biotechnology’s Food Science division at the University of the Free State (UFS) participated in a webinar by the Integra Trust, titled Heal the Land, Heal the People.

The Integra Trust was established to advance climate-smart sustainable and regenerative agriculture. It values the production, distribution, and utilisation of food with integrity in order to heal the land and the people.

Integra Trust strives to promote agriculture that has a limited footprint on the environment.

Prof Hugo’s lecture during the session on food with integrity, focused on the importance of the traceability of food and the information communicated to the consumer. 

Physical and emotional connectedness to farm and the producer
According to him, modern consumers want to know where their food comes from and want to be physically and emotionally connected to the farm and the producer. In the case of meat, for example, they want to know if the meat they buy is ethically produced and whether the animal was treated in a humane manner during the slaughter process. They also want a guarantee that the food they buy is free of harmful substances.

Prof Hugo states: “The consumer’s need for origin-based food is now playing out in a variety of ways, as food processors and retailers are labelling their products according to the origin of the product. One way of achieving this, is through a good traceability system.”

In his presentation, he focused on traceability from a meat industry perspective.

“Thus, in a good traceability system, a product on the store shelf can easily be traced back to the farmer and the farm where the food was originally produced. In modern traceability systems, it is even possible for the consumer to take the product in the store to a scanner that can read the ‘barcode’ and then showing a photo of the farmer and the name and location of the farm where it was produced,” explains Prof Hugo.

Food traceability important from food safety point of view
“Despite the consumer’s emotional need to connect with the farm and the producer, food traceability is also extremely important from a food security and food safety point of view,” he adds.

Although in its simplest form, it is a comprehensive process of keeping record of suppliers and customers in order to allow reconstruction of the product chain in case of need, it is doable. “In Europe, some 25 million cattle per year are now slaughtered with full traceability. The challenge of providing a secure form of identity through this process, is therefore a formidable one. This is achieved with the use of modern technologies such as Blockchain and DNA technology,” explains Prof Hugo. 

Joining him in the session on food with integrity were, among others, Errieda du Toit, chef, food writer, and culinary commentator (talking about perceptions in terms of difference between fast food and story food, asking if it is driven by social media) and Christiaan Campbell, chef and food consultant (talking about achieving synergy and communication between producer and consumer via the food value chain). Steven Barnard of Farmer Kidz presented a session focused on the younger generation, focusing on why it is important to connect children with food production.

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.
