As per a research, which has been taken by researchers at the Duke University Medical Center and Norway's University of Life Science, it has been revealed that it is all in human genes that how they perceive pork smell.
It is said the gene depicts that human will perceive pork smell as ammonia, urine, vanilla or sweat. It is said that people prefer to have pork, if its testicles are removed. Co-author of the study Dr. Hiroaki Matsunami, who is an associate professor of molecular genetics and microbiology at Duke University Medical Center, was of the view that there is reason behind that why humans prefer castrated pork.
The reason is that the compound in pork called androstenone is less detectable at the time when its testicles are removed. In order to reach at the above given result, the study researchers asked 23 people to smell the pork and tell accordingly that whether or not they liked the smell of it.
Blood samples of all the 23 people were taken, said Matsunami. They further affirmed that those, who did not like the smell of pork, were found to be having double copy of a gene known as OR7D4. Those who liked the smell of pork were having one copy of the gene.
It was found that 70% people had double copies of the gene. At some places like North America and Europe, pigs are castrated, so they do not feel the smell of androstenone much. There are places where castration is banned and such practice is prevalent in countries where pigs are thought to be sacred.
"The data raise the possibility that more consumers will dislike male meat as a result of a castration ban", said the study authors.
