Flammability code 1: Must be pre-heated before list eight common uses of enzymes in industry can occur. Health code 0: Exposure under fire conditions would offer no hazard beyond that of ordinary combustible material. Reactivity code 0: Normally stable, even under fire exposure conditions, and is not reactive with water. Sucrose is produced naturally in plants, from which table sugar is refined. Sugar mills are located where sugar cane is grown to crush the cane and produce raw sugar which is shipped around the world for refining into pure sucrose.
Some sugar mills also process the raw sugar into pure sucrose. Sugar beet factories are in colder climates where the beet is grown and process the beets directly into refined sugar. The sugar refining process involves washing the raw sugar crystals before dissolving them into a sugar syrup which is filtered and then passed over carbon to remove any residual colour. The by now clear sugar syrup is then concentrated by boiling under vacuum and crystallised as the final purification process to produce crystals of pure sucrose. These crystals are clear, odourless, and have a sweet taste. En masse, the crystals appear white. Saccharose is an obsolete name for sugars in general, especially sucrose. C2 on the fructosyl unit. Fructose itself exists as a mixture of “furanoses”, each of which having α and β isomers, but only one particular isomer links to the glucosyl unit.
What is notable about sucrose is that, unlike most disaccharides, the glycosidic bond is formed between the reducing ends of both glucose and fructose, and not between the reducing end of one and the nonreducing end of the other. This linkage inhibits further bonding to other saccharide units. Commercial samples of sugar are assayed using this parameter. Sucrose does not deteriorate at ambient conditions. Solubility of sucrose in water vs. Sucrose does not melt at high temperatures. This reaction is somewhat simplified though. Likewise, gastric acidity converts sucrose to glucose and fructose during digestion, the bond between them being an acetal bond which can be broken by an acid. Many mammals, birds, insects and bacteria accumulate and feed on the sucrose in plants and for some it is their main food source.
As fruits ripen, their sucrose content usually rise sharply, but some fruits contain almost no sucrose at all. This includes grapes, cherries, blueberries, blackberries, figs, pomegranates, tomatoes, avocados, lemons and limes. Table sugar production in the 19th century. The picture shows workers harvesting cane, loading it on a boat for transport to the plant, while a European overseer watches in the lower right.
The lower image shows a sugar plant with two furnace chimneys. Sugar plants and plantations were harsh, inhumane work. The production of table sugar has a long history. Further, it appears that by about 500 BC, residents of present-day India began making sugar syrup and cooling it in large flat bowls to make raw table sugar crystals that were easier to store and transport. On their return journey, the Greek soldiers carried back some of the “honey-bearing reeds”.
