LIMIT OF DETECTION. One furanone diasteriomer (maltols: coffee, butter, chocolate, beer) has a threshold of 0.00001 Ng/L of air. https://lnkd.in/emSBr8y View in LinkedIn

350 IMPORTANT AROMAS. "The results of dilution analyses and of aroma simulation experiments show that only 5% of the more than 7,000 volatile compounds identified in foods contribute to aromas. The main reason for the low number of odorants in the volatile fraction is the marked specificity of the sense of smell." https://lnkd.in/emSBr8y View in LinkedIn

SMELL AND MORE SMELLY. This remarkable review of the chemistry of smells gives you a sense of how sophisticated food science has become, with every subtle scent known to a deep level. https://lnkd.in/emSBr8y View in LinkedIn

SMELL AND MORE SMELLY. What a deep knowledge and library we have for adulterating natural smells by food chemistry. A high percentage of natural oils are adulterated. https://lnkd.in/emSBr8y View in LinkedIn

ALICE IN WONDERLAND. "For example, lemons would smell like oranges and oranges would smell like lemons, because R-limonene (a 15-carbon oil) gives the odor to oranges and S-limonene, its mirror image, gives the odor to lemons." https://lnkd.in/ejqs2rT View in LinkedIn

ALICE IN WONDERLAND. "In Wonderland, spearmint chewing gum, which gets its minty flavor from R-carvone, would taste like caraway seeds, which get their flavor from the mirror-image molecule, S-carvone." https://lnkd.in/ejqs2rT View in LinkedIn

CHIRAL SMELLS. "One of the most important factors affecting both the intensity and the type of odor is the configuration of chiral centers in the molecule." https://lnkd.in/eMTZmZF View in LinkedIn

SMELL AND CHIRALITY. "The two mirror-image forms of a chiral molecule may have very different smells, such as spearmint and the spice caraway, which tastes like cumin." These are carvone enantiomer molecules. https://lnkd.in/eqzkdcz View in LinkedIn

BIOLOGICAL ACTIVITY. "Due to the chirality of receptor molecules, the taste, odor, or drug activity of enantiomers can be very different." https://lnkd.in/eD3BZKr View in LinkedIn

FRAGMENT IN NATURE for the next few weekends will deal with the remarkably ability of plants to sense their environment through their equivalent of the sense of smell. View in LinkedIn
