Hydration is an important process in many other applications; one example is the production of Portland cement by the crosslinking of calcium oxides and silicates that is induced by water. Hydration is the process by which desiccants function. CuSO 4 ·5H 2 O is bright blue and has a rather different structure from its colourless anhydrous ...
The following are examples of topics in food physical chemistry that are of interest to both the food industry and food science: Starch, 800x magnified, under polarized light Macaroni is an extruded hollow pasta. Water in foods Local structure in liquid water; Micro-crystallization in ice cream emulsions
Because of the removal of the water molecule from the product, the term of convenience for such a process is "dehydration reaction" (also "condensation reaction" or "dehydration synthesis"). For example, milk sugar (lactose) is a disaccharide made by condensation of one molecule of each of the monosaccharides glucose and galactose, whereas the ...
For example: ethanol, CH 3 −CH 2 −OH, is the product of the hydration reaction of ethene, CH 2 =CH 2, formed by the addition of H to one C and OH to the other C, and so can be considered as the hydrate of ethene. A molecule of water may be eliminated, for example, by the action of sulfuric acid.
The classic example of a dehydration reaction is the Fischer esterification, which involves treating a carboxylic acid with an alcohol to give an ester RCO 2 H + R′OH ⇌ RCO 2 R′ + H 2 O. Often such reactions require the presence of a dehydrating agent, i.e. a substance that reacts with water.
Dietitians share the best hydrating foods to add to your diet—like melons, cucumbers, cabbage, and more. Women need need at least 91 ounces (2.7 L) of water.
With the spread of appertisation, the 19th-century world entered the era of the "food industry", which developed new products such as canned salt meat (for example corned beef). The desire for safer food led to the creation of the US's Pure Food and Drug Act in 1906, followed by the national agencies for health security and the establishment of ...
As we head into the heart of the summer, it is important to always stay well hydrated. In case you are sick of boring old ice water, we have a few new ideas to help you keep the thirst away this ...
