Human body odour sources

Abstract Human body odour is individually specific and several lines of evidence suggest that to some extent it is under genetic control. There are however numerous other sources of variation, commonly labelled as environmental factors, which are the main aim of this paper. These include 1) reproductive status, 2) emotional state, 3) diet and 4) diseases. We primarily focus on axillary and genital odours as they have been proposed to have communicative function. We prelusively conclude that a specific diet and some diseases have major impact on variations in human body odour. 

Okayama, Japan. He reported his new enzyme system in 2002, which he had extracted from a bacterium. This will convert starch to trehalose in high yields, bringing down its cost to 1% of what it had been when it was extracted from natural sources such as yeast. Hayashibara also reported that trehalose suppresses human body odour, especially that given off by old people who produce the somewhat odorous chemicals 2-nonenal and 2-octenal41)in their skin. When they use a 2% solution of trehalose as a body lotion it reduces the emission of these smelly compounds by about 70%. Maybe one day it will find cosmetic uses and no doubt be added to deodorants and body lotions, as the following advert from the future shows ...
