LOUISVILLE, Ky.--(BUSINESS WIRE)--Sep 21, 2023--

It’s hard to resist garlic sometimes, but its pungent smell can often last long on the tongue and what better way to get rid of it than good old yoghurt? Garlic contains a compound called sulfur volatiles that can cause a bad odour after being eaten. Researchers wanted to better understand how yoghurt and its components can eliminate or reduce such strong odours. For the study, researchers from the Department of Food Science and Technology at Ohio State University, Columbus tested the garlic deodourising capabilities of yoghurt and its individual components of water, fat and protein to see how each stood up to the smell. As a result, the team found both fast and protein were effective at trapping garlic odours, leading the scientists to suggest high-protein foods may one day be formulated specifically to fight garlic breath. “High protein is a very hot thing right now – generally, people want to eat more protein,” said senior study author Sheryl Barringer, professor of food science and technology at the university. “An unintended side benefit may be a high-protein formulation that could be advertised as a breath deodorizer in addition to its nutritional claims,” she said. “I was more excited about the protein’s effectiveness because consumer advice to eat a high-fat food is not going to go over well.” In the lab experiment, researchers placed equal amounts of raw garlic in glass bottles and confirmed the smell of the garlic was released in concentrations that would be detected by the human nose. Scientists measured the levels of volatile molecules in gaseous form present before and after each treatment. It was revealed that garlic alone reduced 99 per cent of the major odour-producing raw garlic volatiles. When introduced separately, the fat, water and protein components of yoghurt also had a deodorising effect on raw garlic, but results showed fat and protein performed better than water. Looking at fat’s performance, a higher quantity of butter fat was more effective at deodorisation. The proteins which were studied included different forms of whey, casein and milk proteins, all of which were effective at deodorising garlic. This may be because of their ability to trap the volatile molecules before they are emitted into the air. A casein micelle-whey protein complex performed the best. “We know proteins bind flavour – a lot of times that’s considered a negative, especially if a food with high protein has less flavour. In this case, it could be a positive,” Barringer said. Additional experiments that involved changing the pH of the yoghurt to make it less acidic (4.4 pH to 7 pH) actually appeared to lower the yoghurt’s deodorisation effect on the garlic. However, changing the pH of water did not seem to make any difference on the water’s deodorization effect. “That’s telling me it goes back to those proteins because as you change pH you change the configuration of proteins and their ability to bind. That said we definitely should be looking at these proteins,” Barringer said. “It probably depends on the protein, as well, because different proteins react differently to pH. So that may be an important thing as we look at other proteins for their garlic deodorization effect.” The team also tested the deodorising effect of yoghurt and its components on fried garlic, in the process they found that drying garlic alone can significantly reduce garlic odour. Yoghurt and its individual ingredients neutralised a lower percentage of volatile compounds of fried garlic compared to raw garlic. Study authors think this may be because there were fewer volatiles to trap than were present in the raw cloves. The findings have provided a foundation for future studies on proteins that might help fight the garlic breath. In the meantime, Barringer predicts that Greek yoghurt, with a higher protein profile than the whole milk plain yoghurt used in the study, may be particularly effective at getting rid of garlic breath. Fruit-flavoured yoghurts will probably work, too, she said – and whatever is used, it must quickly follow ingestion of raw garlic. “With apples, we have always said to eat them immediately,” she added. “The same with yoghurt is presumed to be the case – have your garlic and eat the yoghurt right away.” The study was published in the journal Molecules.

Sebastian Vettel was back in the Formula 1 paddock on Thursday as he unveiled a number of “bee hotels” at the Suzuka circuit. The four-time F1 world champion, who retired last year, is the leading voice in the sport on the environment and climate change – and continues to use his platform within the sport even after leaving the grid. Present at his favourite track in Japan, Vettel invited all the drivers and teams to turn two of the track on Thursday, where he has formed a set of specially-created insect hotels. The message behind the project is to spread the word of the importance of biodiversity in our ecosystems. Each team was able to customise and paint their hotel, while the kerb at turn 2 was painted yellow and black. “I want, with this project, to create awareness about the importance and the subject of biodiversity,” Vettel said. “[The bee is] the perfect ambassador for us around this project and idea to highlight the importance of biodiversity, because it stands not just for the bee but for all the other insects, so we see the bee as our ambassador. She will help us stress this very important message. “It’s very exciting and a lot of work and passion went into the project. Hopefully this is just the beginning of an initiative and projects around the world… standing up for biodiversity, which is not just insects, it’s all types of animals. “But it’s more than that as well: it’s all types of plants, all types of organisms, bacteria. And even more than that, we have to celebrate variety, not just in human beings, but also in nature – and we have to protect it.” Lewis Hamilton was full of praise for his former rival for passionately raising awareness for issues close to his heart. “It’s great to see that he’s found his purpose,” Hamilton said. “It’s great to have Seb back this weekend. He sat down and told all the drivers about these plans. “To be honest, in the history of the sport, I don’t know any other driver who’s ever been so outspoken and shown real compassion for the world outside of this little world that we’re living in. It’s really great that he’s utilising his platform. “I always just hope that with the things that he’s doing, for example, that he inspires the other drivers to do something here – maybe in their own lane. “But we all need to come together in this world to have a positive impact; to spread love, to spread compassion, to raise awareness for a lot of the problems – and there’s obviously millions of problems that we need to address – but biodiversity is for sure.” Read More Lewis Hamilton says ‘something’s up’ at Red Bull – if Max Verstappen struggles in Japan Lando Norris calls for ‘harsher penalties’ after Max Verstappen incident George Russell insists 2023 has been his ‘best season ever’ despite Singapore crash

'The Devil Wears Prada' star Anne Hathaway used to feel "badly" about herself in certain outfits.

Lewis Hamilton expects Red Bull to return to their imperious form of 2023 this weekend in Japan - insisting “something’s up” if that doesn’t prove to be the case. Red Bull had won 14 from 14 races prior to last weekend’s Singapore Grand Prix but struggled in the twists and turns of the city-state, with both cars failing to qualify for Q3 and Max Verstappen finishing only fifth in Sunday’s race. However, a return to a more traditional track at Suzuka this weekend is expected to coincide with business as usual for Christian Horner’s team. Max Verstappen cannot secure his third-straight world title in Japan this weekend but is the favourite once again, with seven-time world champion Hamilton expecting Red Bull to be back on top by some margin. “I would think that if they’re [Red Bull] not 30 seconds ahead, like they have done in the past, then something’s up,” Hamilton said. “It was obviously a difficult weekend the last one but their car should be phenomenal here. They’ve been phenomenal all year long, their pace at pretty much every circuit. “It’s going to be great to watch that car in general. Normally, you’d come here and it’s beautiful to watch the laps that they do because the whole team and the drivers are doing an amazing job with the package they have. So it’ll be interesting to see how the weekend goes. “I hope we’ll be closer and I hope they’re not as fast as that 30-second gap they’ve had in the past.” Verstappen secured his second world title in Japan last year after a chaotic, wet race in Japan. The Dutchman, who has a 151-point lead in the drivers’ championship, emphasised he wasn’t overly bothered at his own record-breaking win-streak of 10 coming to an end in Singapore. “I have no emotion,” Verstappen said. “We stopped winning for one race. S*** happens! We won 10 in a row before that. “Of course I would have liked to win there as well. But I also know that there is always going to be a day where you have done that weekend where then you’re not winning or things go wrong. And yeah, unfortunately, it was that weekend. “We just move on and try again.” Read More Lando Norris calls for ‘harsher penalties’ after Max Verstappen incident Ferrari finally find their chief strategist – and it’s Carlos Sainz Mercedes boss Toto Wolff to miss Japanese Grand Prix Lando Norris calls for ‘harsher penalties’ after Max Verstappen incident Rising F1 star Oscar Piastri makes decision on McLaren future Carlos Sainz would be a ‘good fit’ for Audi seat in 2026, says Johnny Herbert

George Russell believes this season has been his best ever in terms of performance as he refused to dwell on his last-lap crash in Singapore. Russell put his Mercedes into the barriers as he chased down Lando Norris and race winner Carlos Sainz on the draining street circuit. The 25-year-old was visibly emotional afterwards following a strong weekend where he qualified second and held the edge over his team-mate Lewis Hamilton but is keen to move on quickly. “In terms of pure performance I feel that this has been my best season ever,” Russell said ahead of the Japanese Grand Prix. “But I reckon there is over 60 points that we have lost this season for a number of different reasons. “I have got an objective this year to secure P2 in the constructors’ championship for the team. It was quite clear this year from the beginning that we were not going to be fighting for a championship and I don’t know if that’s had an impact on my mentality or not. “There is a reason for all mistakes and that is just pushing to the limit and in some instances pushing over the limit to try and achieve what is possible. I think when I look at my championship-winning years in junior formulas I was the driver who kept on getting results, it’s the long game. “I can assure you once we are in a position again to win a championship I will be back to the ways that I know how to win a championship.” Russell has no regrets over pushing to try and claim the victory over the ailing Sainz and Norris. “If I knew it was the last lap and I took it easy and Lewis overtook me I would equally be kicking myself,” Russell added. “We are on to the next one and it is behind us, in life you can let these setbacks dwell on you. You can overthink and let it consume you but ultimately that brings nothing. You have to have that moment when it knocks you down. “Shov (Mercedes’ chief race engineer Andrew Shovlin) called me Sunday evening and said ‘the only reason we were in that position to fight for a win was because of how incredibly you’d driven all weekend’. I'm not going to let a mistake of 2cm cloud my whole weekend George Russell “He said ‘you gave us that feeling of what it is like to fight for victory again so take that away from the weekend’. “I take the positives, really pleased with the overall performance. I’m not going to let a mistake of 2cm cloud my whole weekend.” Norris clipped the barriers just ahead of Russell but survived the impact and the Mercedes driver feels it played a part. “When Lando hit the wall, the thought process is so quick in your brain because I saw him hit the wall and I thought ‘Oh my God he hit the wall’ and then I hit the wall,” Russell added. “Either the distraction of him clipping the wall was a factor or I was following his tracks or it was just a silly mistake but it seems a bit too much of a coincidence.” Mercedes’ strong pace in Singapore may be hard to replicate around the high-speed corners at Suzuka – where Russell believes McLaren are best placed to challenge Red Bull. But Hamilton is excited to return to the Japanese circuit. “I don’t anticipate us having the performance we had in Singapore. We are continuing to try and push the envelope that we have,” Hamilton said. “It (Suzuka) is one of the favourites for all the drivers. It is that historic circuit and an incredible track to drive on. It is one of the greatest layouts that we get to experience in the calendar.” Read More Charity boss speaks out over ‘traumatic’ encounter with royal aide Ukraine war’s heaviest fight rages in east - follow live Lance Stroll to sit out Singapore Grand Prix after huge crash in qualifying ‘You can forget about that’ – Max Verstappen rules out another win in Singapore Lance Stroll crashes into barrier at 110mph in Singapore Grand Prix qualifying
