Rotimi Aluko, professor, University of Manitoba
Rotimi Aluko is a professor at the University of Manitoba (UM) in the Department of Food and Human Nutritional Sciences, as well as director of the Richardson Centre for Food Technology and Research. Originally from Nigeria, he completed his undergraduate and master’s degrees in biochemistry there before earning a PhD in food science at the University of Guelph. He moved to Winnipeg in 2001, where he lives with his wife. Their two children are grown; one lives in Winnipeg and the other is in Alberta.
Where did you work before UM?
I’ve been here for 25 years, but before UM I worked as a research scientist with Agriculture and Agri-Food Canada (AAFC) in Saskatoon.
What got you interested in becoming a professor?
From my undergraduate days I was fascinated by my professors, how they taught, carried themselves and were respected in society. I worked as a scientist with AAFC after my PhD, but I was always on the lookout for a professorial position. It had been a longtime goal, so when the opportunity came up, I took it.
Tell us a bit about what you’re working on at UM.
If I’m not teaching, I’m usually giving feedback on various documents. This includes grant applications, student theses and manuscripts, and preparing documents that highlight the centre’s activities.
In one of our current research projects, “Genotype and environment effects on sunflower and new sunflower protein study,” co-funded by Manitoba Crop Alliance (MCA), we are looking at genotype versus environment effects on sunflower seed protein content and quality.
This project has two main objectives. First, we are quantifying chlorogenic acid, the compound that causes sunflower protein to turn greenish during aqueous processing. That colour isn’t always desirable in food products, so we are screening different varieties to identify those with lower levels of chlorogenic acid. We are also screening different growing environments to see if that affects the chlorogenic acid content. If we can identify varieties with low chlorogenic acid, they could be recommended to farmers, assuming all other aspects of the seed are acceptable.
Second, we are looking at protein quality. Proteins are made up of units called amino acids, and the quality of the protein is determined by the amino acids present that the human body cannot synthesize on its own. We are developing a rapid system to measure essential amino acids, which determine protein quality. The goal is to identify sunflower varieties and growing locations that result in higher-quality protein for use in the food industry.
What can you say about the value of farmers providing funding and support to your organization?
It’s invaluable. This research would not be possible without the financial support and collaboration of farmers and MCA. Beyond funding, farmers also provide the seeds to do the work. That level of support allows us to generate results that can be applied back to the industry.
How does that farmer funding and support directly benefit farmers?
The goal of this project is to identify sunflower varieties that produce high-quality protein with a desirable colour for food use. That creates stronger demand from the food industry, especially with growing interest in plant-based products. If successful, this will give Manitoba farmers an advantage by producing seeds that are more valuable in the marketplace and can improve returns.
How do you spend your time outside of work?
I am a history buff. I like to learn about history by relaxing and watching documentaries.
What gets you most excited about your work?
When we get results that meet our objectives and lead to useful outcomes, whether for the food industry or farmers, that’s what excites me. It shows the time and investment in the research is making a real impact.
What are you excited about for the future of agriculture?
I am excited about the growing emphasis on plant-based foods. The cultivation of crops is sustainable, and the current emphasis on using more plant products in our food system is highly encouraging because it points to a more sustainable future for food, agriculture and human nutrition.
What is your favourite food or meal?
As a Nigerian, my favourite food is Jollof rice. It is a specialty rice dish with a unique preparation, and I think it’s traditionally made in Nigeria and Ghana. It’s a wonderful dish with many different versions: spicy or not spicy, with vegetables, meat or fish.
