Lye made out of wood ashes is also used in the nixtamalization process of hominy corn by the tribes of the Eastern Woodlands in North America. In the United States, food-grade lye must meet the requirements outlined in the Food Chemicals Codex (FCC), [5] as prescribed by the U.S. Food and Drug Administration (FDA). [6]
Oleuropein is a derivative of elenolic acid linked to the orthodiphenol hydroxytyrosol by an ester bond and to a molecule of glucose by a glycosidic bond. [4] When olives are immersed in a lye solution, the alkaline conditions lead to hydrolysis of the ester bond.
Theoretical astronomers use a wide variety of tools which include analytical models (for example, polytropes to approximate the behaviors of a star) and computational numerical simulations. Each has some advantages. Analytical models of a process are generally better for giving insight into the heart of what is going on.
Once harvested, the naturally bitter kalamata olives are soaked in a brining solution and left to ferment in order to increase their sodium and water content, whilst achieving a plumper, tastier ...
Olives are often soaked in sodium hydroxide for softening; pretzels and German lye rolls are glazed with a sodium hydroxide solution before baking to make them crisp. Owing to the difficulty in obtaining food grade sodium hydroxide in small quantities for home use, sodium carbonate is often used in place of sodium hydroxide. [46]
Adam Guy Riess (born December 16, 1969) is an American astrophysicist and Bloomberg Distinguished Professor at Johns Hopkins University and the Space Telescope Science Institute. He is known for his research in using supernovae as cosmological probes.
The team devised a way to measure the surface gravity of distant stars to help determine if the planets in their orbit have life-supporting conditions.
Astrochemistry overlaps with astrophysics and nuclear physics in characterizing the nuclear reactions which occur in stars, as well as the structure of stellar interiors. If a star develops a largely convective envelope, dredge-up events can occur, bringing the products of nuclear burning to the surface.
