The clever reason oranges are always sold in red mesh bags

You may have wondered why this fruit is typically sold in a very specific way.
A food expert has revealed why a popular fruit always seems to be sold in a specific type of packaging. It might seem strange but selling oranges in a red mesh bag actually makes them more appealing to shoppers.
In a video uploaded to social media platform TikTok, food technology expert and author Miguel A. Lurueña revealed what it is about this packaging that makes us more likely to buy the fruit. Speaking to his thousands of followers, he said: "Have you noticed that oranges are always sold in red mesh bags? It's no coincidence."
‌
As reported by Spanish news site El Confidencial, the aim is to enhance the natural colour of the food and make it more attractive to the consumer's eyes. This aesthetic decision actually directly plays with our visual perception.
‌
According to Lurueña, who is from Spain, it is a supermarket trick based on a phenomenon known as the Munker illusion, named after German researcher Franz Carl Munker in the 1970s. This optical illusion causes the colour we perceive of an object to be altered by the colours surrounding it.
In his video, Lurueña shows a visual example. In an image created by himself, the same fruit appears to have more intense shades when crossed by red lines. "The fruit in the middle seems much more orange than the other two due to the red lines passing over it,' he said.
'However, the colour of all three fruits is exactly the same," commented the expert. The Munker illusion means that the colour of an object can appear different depending on the background colour or surrounding elements.
In the case of food, this visual manipulation can be used to make fruits and vegetables appear fresher and riper than they really are. Red is able to intensify warm tones like orange and yellow, resulting in a more appetising appearance.
This technique is not only applied to selling oranges. The former university lecturer also shared that it used with other fresh products such as lemons, peppers, avocados, onions, and purple garlic.
The goal is always to enhance the natural colour of the food and make it more attractive to shoppers.
Lurueña added: "So don't trust your senses. Read labels carefully and try to buy fruits and vegetables in bulk to avoid surprises.'

Scots river 'has second-highest levels of fertility-harming chemical ever found'

Joint research by York University and Scots environmental charity Fidra raised alarm on contamination of 'forever chemical' TFA in rivers. A Scots river has been found to have the second highest concentration of a toxic chemical thought to harm human fertility ever found in the world. Joint research by York University and environmental charity Fidra has raised the alarm on levels of TFA (trifluoroacetic acid) in ­ Glasgow's River Kelvin. ‌ The 'forever chemical' takes more than 1000 years to break down in the environment and German government scientists recently pushed for the EU to classify it as toxic to ­reproduction amid growing fears. ‌ TFA was found in 31 of 32 UK rivers surveyed by researchers, however the highest concentration of 78,464ng (nanograms) per litre was found in the Kelvin – the second highest recorded globally. Sally Johnston, chair of Friends of the River Kelvin, said: 'We need answers on what is causing it and who is accountable. 'It's good to get evidence because then we can action things from there. But the researchers don't even know what the source of this is and it's multifarious. 'We are an urban river. Close to roads, it has been an industrialised river in the past, it's a river that's in recovery. There were 55 working mills on the Kelvin at one point, so it could be a historical issue. But as a little group, we don't have the capacity to do chemical analysis.' Johnston said it had been a 'frantic' week for volunteers after the findings, with dog walkers asking if the Kelvin is still safe for them and their pets. ‌ But she stressed: "We've still got a beautiful river here with amazing wildlife. It's a good thing that people become more aware of things like forever chemicals.' "We blindly consume and then we start to ask questions when they become meaningful to us. "So if this raises a bit of awareness and we can ask questions and get the right information, it's ultimately about becoming more knowledgeable and then being able to act on that." ‌ TFA, which may also harm unborn babies, has been found in drinking water, wine and food, blood and breast milk. Only the record 140,000ng per litre found in the Neckar River in Germany in 2016 is worse. Join the Daily Record WhatsApp community!

Alistair Boxall of York University said: 'It is likely levels in drinking water will be similar to those we found in some of the rivers. While there are methods to remove TFA from drinking water, these are very expensive and likely impractical. ‌ 'We urgently need to stop ­chemicals like TFA at source so they don't get into our environment.' Hannah Evans of Fidra said: 'We're asking the UK Government to turn off the tap of these ­persistent forever chemicals.' Germany's Federal Office for Chemicals last month said TFA 'may cause harm to the unborn child' and 'may impair fertility'. Environment watchdog Sepa said: 'We are considering the contents of this report and will be engaging with the researchers to better understand their findings.'

Alexandra Palace is hosting a massive sleepover soundtracked by Max Richter

London's arts institutions love a good sleepover. You can already get 40 winks at the Natural History Museum' Dino Snores nights, the Science Museum's Astronights and the British Museum's sleepovers, and now another beloved London arts venue is hosting a truly special, limited-edition overnight experience this September in collaboration with British-German composer Max Richter in celebration of the tenth anniversary of his opus, SLEEP. Comprising 204 individual tracks, SLEEP is an epic, 8 hour and 30 minute-long lullaby created for listeners to fall asleep to, and has previously been performed live at overnight events in a bunch of iconic global settings, including Sydney Opera House, the Philharmonie de Paris and The Great Wall of China. The events – and the mammoth task of preparing for such lengthy performances – were also captured in a documentary of the same name, directed by Richter's creative partner Yulia Mahr. And now it's the turn of Alexandra Palace to host more of his truly special all-nighters. The north London music venue will be hosting two performances of SLEEP this September, marking the first time the piece has been performed in London since 2017. The concerts will start at 10pm and finish at around 6am as the sun rises, and audiences will be provided with beds and bedding, as well as being served a light breakfast at the end of the night. Fancy bunkering down in the Grade II-listed Great Hall for the night? Tickets for the event are on sale now via the Alexandra Palace website, with prices starting at £249.75 (steep for a concert, yes, but not unreasonable for a one-night stay in one of London's fancier hotels, which is how we prefer to think of the experience!)
