Boar taint is an unpleasant smell that can arise during the heating of pork. Boar taint can occurparticularly in meat of adult male pigs due to changes in the hormonal system when the animal is growing older. This may lead to a concentration and combination of endogenous substances in the body fat that can cause the different smell. Boar taint rarely occurs in female pigs or castrated male pigs. Meat products that are not heated will also not show boar taint.
Research has shown that there are three endogenous substances that can cause boar taint: androstenone, skatole and indole. Androstenone is a substance that is important in the development of the sperm cells in male animals. lawn mower reviews Skatole is produced during the degradation of certain amino acids in the body. Skatole affects both male and female animals. In male pigs incidentally three times more than in female pigs. Castration of male piglets lowers the concentration of Skatole significantly. Ultimately, it is the combination and concentration of androstenone, skatole and indole which cause -the extent of- boar taint.
The detection and prevention of boar taint is particularly complex. It’s not just about finding the concentration of substances but also how consumers perceive the smell and taste of these substances. These are not uniform. Research has shown that 30% of consumers is not sensitive to androstenone. Differences are also found between consumers in different countries.
That in turn can have various causes, such as a cooking method or getting used to a product.In recent years, much research has been conducted to gain insights into consumer preferences. That the level of androstenone, skatole and indole are influencing the smell is for sure. Other conclusions are not possible. Given the complexity of boar taint it must also be added that consumer taste can differ as well.
In the world and also in Europe, the castration of male piglets is regarded as the most common method to prevent boar taint. After castration androstenone and skatole are virtually disappeared.
In recent years much research has been carried out to identify the causes of boar taint and the ways to prevent it.
Using the above mentioned measure, more and more major pork supply chains in Europe have succesfully adapted the practice of producing and marketing entire male pigs.

The five-year Dutch research program ‘stopping the castration of piglets’ was started in 2009. The research results have provided important directions for solutions. The scientists involved have gradually unravelled the consumer response to products from entire male pigs, which is important for the appropriate use of detection methods. We have also identified the factors that determine successful boar management on the farm. Although still some challenges remain to be solved, we are convinced that we are on the right track towards a more sustainable production and marketing of pork products. This report summarizes the knowledge gained up to the present.Further information can be found in the reports of various studies, to which reference is made in the text. We hope that sharing our knowledge with experts throughout the member states of the European Union contributes to the ambition of stopping piglet castration.
