Pioneering work to eliminate food waste will be showcased at the UK’s most prestigious science exhibition by researchers from the University of Lincoln.
The team from the National Centre for Food Manufacturing (NCFM), at the University’s Holbeach Campus, has been working on innovative ways to help consumers significantly reduce food waste, through food preservation and packaging design.
Led by Dr Wayne Martindale, a specialist in food insight and sustainability, the team will be demonstrating their high-tech methods at theRoyal Society Summer Science Exhibitionfrom 1-7 July.
The researchers have created new ways of dehydrating fruit and vegetables to produce flours that can then be used in bakery and snack products, and developed efficient manufacturing methods using freeze driers to turn would-be waste products into tasty and functional ingredients. For example flours made from cauliflower, beetroot and sweet potatoes can be used in pizza bases and bakery products rather than being thrown away or fed to animals.
Using new technologies like this extends the shelf life of fresh produce and in turn reduces food waste, the group emphasised.
Martindale explained: “By putting the consumer at the centre of any assessment of food waste, our aim is to design waste out of every meal.
“Our food choices are global and our work focusses on reducing the risk of food waste happening during its journey to our plates. Beef from Brazil, avocados from Mexico, lamb from New Zealand, wines from South Africa and green beans from Kenya – our food shopping lists have a distinctly international flavour. Responsible sourcing means we must consider how we manufacture, package and preserve ingredients and foods so that safety, quality andsustainability credentials are met.”
At the Royal Society’s Summer Science Exhibition, the NCFM team will host a demonstration calledFinishing Your Plates, in which they will show howpreserving flavours and manufacturing ingredients that are ready to use means every meal is maximised.
As well as highlighting the importance of not buying too much, of preparing just enough and of storing food so that it lasts and remains safe to eat, theFinishing Your Platesdemonstrationwill show exactly how fruit and vegetables can be preserved. It will put what we enjoy and what we do with food at the centre of the sustainability discussion.
“The consumer is key and understanding how food is prepared can help answer many issues as to why sustainable targets are not reached,” Martindale said. “Cooking skills in the food factory and home kitchen are on our research priority list because they are the most likely sources of reducing food waste.It is not just a carbon or waste-reduction debate, it is about innovations that meetconsumer choices. Our food choices are at the core of getting food sustainability right, so this needs to be centre of the plate in terms of research.”
