For over a century, chemists have made flavor molecules to evoke particular tastes. How do they know which compounds create a particular flavor, and how do they make these molecules? cen.acs.org/food/food-sc...

#NationalChemistryWeek #ACS_NCW #SpiceChemistry #chemsky
A three-column infographic, titled “Faking Flavors with Chemistry,” explaining how artificial flavors are formulated and produced.
The first column highlights three early artificial flavors: vanillin (vanilla, 1870s), methyl anthranilate (grape, early 1900s), and diacetyl (butter, 1920s). 
The second column points out that it’s more common for flavors to have several chemical contributors. Chemists determine these using analytical methods. The primary method used is gas chromatography, which separates compounds in a sample according to their boiling points and solubilities. The output tells us how much of each compound is present, and the chromatograph can be connected to a mass spectrometer and a sniff port for further identifying information.
The third column discusses how flavor molecules are made once they’ve been identified. Usually, they’re extracted from plants or made in the lab. However, chemists are turning to biotechnological methods, which allow them to market produced flavor molecules as natural. One method is biosynthesis, in which microbes metabolize simple chemical building blocks to make flavor compounds over multiple reaction steps. Another method is biotransformation, which uses microbes or their isolated enzymes to make flavor compounds from a similar starting substance in simple reactions.

For #NationalChemistryWeek, learn about research on how sunlight transforms dissolved organic matter and sediment plumes in #LakeSuperior, which releases nutrients that may contribute to shoreline blooms.

Dr. Glace-Noire is sitting by a table in his laboratory/garage. On that table there is a propped up whiteboard with the periodic table; there is also a beaker and an Erlenmeyer flask. Dr. Glace-Noire is wearing a button-down lab coat with buttons on the side; he is wearing goggles over his gray, messy hair. The mad scientist speaks in both panels and he is pointing to the board with a stick. Panel 1 —- Fun fact: The letter J does not appear as an element symbol on the periodic table. Panel 2 —- Since there is Uranium and Neptunium, why not name element 119, or beyond after the planet Jupiter when it is synthesized?

There are 6.02 x 10²³ atoms, molecules, or ions in a mole. This number, called Avogadro's number, is a fundamental unit of measure in chemistry. #NationalChemistryWeek

We’re now well into the season of pumpkin spice everything: baked goods, scented candles, and of course, the classic latte. If humans enjoy pumpkin spice so much, what do fungi think of the ubiquitous fall flavor?
