Why we smell things differently<\/b><\/h1>\n<\/div>\n<\/td>\n<\/tr>\n

Our genes determine how we smell things<\/div>\n<\/div>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

Scientists believe they may have found out why we all smell and taste things very differently.\u00a0<\/b><\/span><\/span>Our ability to smell and taste is regulated by around 1,000 genes, over half of which are totally inactive.<\/p>\n

However, a study by researchers in Israel has identified at least 50 of these genes, which are switched on in some people and not in others.<\/p>\n

They believe this may explain why some of us adore some smells and tastes while others abhor them.<\/p>\n

Researchers at the Weizmann Institute say their study shows that nearly every human being displays a different pattern of active and inactive odour-detecting receptors.<\/p>\n

These receptors determine how our brain reads flavours in food as well as smells.<\/p>\n\n\n\n

The huge variation occurs because different receptors are switched on in different people and also because their sensitivity also differs.<\/p>\n

The researchers have also found evidence to suggest people from different ethnic groups perceive aromas and flavours differently.<\/p>\n

Industry revolution<\/b><\/p>\n

They suggested their findings could revolutionise the way food, drink and perfume manufactures work.<\/p>\n

At the moment, many companies base a decision on whether or not to make particular products on the reaction of test panels, usually comprising just a few people.<\/p>\n

The researchers suggest these companies might want to rethink this policy in light of their findings.<\/p>\n

But they also believe that these companies could one day test the potential popularity of their products using a computer chip.<\/p>\n

They suggest these chips could be designed so that they replicate the taste and smell preferences of target markets.<\/p>\n

Companies that make foods, perfumes and similar products have already started to keep a close eye on research in this area.<\/p>\n

“Fragrances are more about art than science at the moment,” said Dr Tony Curtis, who teaches on the aroma and fragrances degree course at the University of Plymouth.<\/p>\n

“Everybody is looking for a scientific platform on which they can create fragrances.<\/p>\n

“They would like to shorten the development cycle of products and minimise the risk,” he told BBC News Online.<\/p>\n

“We know how we see and how we hear. People are struggling to understand how we smell.<\/p>\n

“But certainly when we get there it will revolutionise how people construct fragrances and how we evaluate them.”<\/p>\n

The study is published in the journal Nature Genetics.\u00a0<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
