The average household throws away nearly £500 worth of food every year - with milk top of the list, according to a new study. Researchers found that we typically spend £61 every week on food and drink, but the equivalent of £9 of that will end up in the bin after going out of date. A third of the 2,000 people polled say milk is the most common product they dispose of, followed other dairy products such as yogurt, butter and cheese. Divya Chopra, CEO at Noluma, which commissioned the research, said, “With each Brit throwing away an estimated £500 a year in out-of-date food as a result of inadequate packaging or storage, it is clear the issue has significant financial implications. “This can be reduced through consumer education, protection from indoor light damage, and better packaging." The best-before and use-by date debate The study found that one in five Brits are happy consuming an item which has passed its use-by date, and more than a third are willing to risk a bite on a product past its best-before date. Those polled believe cheese is safe to eat 10 days on from its use-by, and that milk has a grace period of five days beyond the marked date. A pot of yogurt is still deemed good to go six days after its time has come, while Brits believe biscuits, soft drinks and condiments are all safe to consume for a further two weeks. When it comes to correct food storage, three in five think the rightful home of a carton of eggs is in the fridge, while one in seven will opt to store them in the cupboard or on the side. But more than a third prefer their chocolate treats refrigerated, compared to 45 per cent who demand their confectionery at room temperature. When it comes to bread, 42 per cent leave their loaf to its own devices in the cupboard, and one in four keep it on the worktop or side. And three in 10 Brits flirt with disaster by keeping their mayonnaise outside of a refrigerated environment. How to store food Storing food in the wrong place was identified as the reason an item is most likely to go off before its time, followed by exposure to heat and being stored in damaged or open packaging. Although more than two thirds of people were unaware that exposure to a light source can cause certain foods and packaging to deteriorate at a faster rate. And only one in 10 Brits quizzed, via OnePoll, identified light-protected packaging as an effective way to keep products fresh up to their use-by date. Chopra added, “We think Brits should also be made aware of some of the other factors which can lead their favourite foods and beverages to sour before they can be used, such as the surprising impact of indoor light on certain products, including LED, fluorescent and refrigerator lights. “Correct storage and light-protected packaging is important, to prevent foods from going off sooner than we expect. “Certification of light-protection is the only way for consumers to be assured that the produce they are buying is being light-protected by the highest industry standards.”
