Sugar cane

Sugarcane (Saccharum sp. hybrids) is a highly productive C4 grass used as the main source of sugar and more recently to produce ethanol, a renewable transportation fuel.

Cane sugar first achieved dominance on the subcontinent of India more than 2500 years ago, and it was in that country and China that commercial sugar was first produced from sugarcane.

It was not until the early eighteenth century, however, that sugar began to become widely used in western Europe.

 Commercial sugarcane is grown as a source of sugar (sucrose) for human food. By-products from processing sugarcane into sugar such as molasses and bagasse have been mainly used as additives in stockfeed.

Sugar cane is a tropical crop requiring a hot climate. However, it also grows well in a subtropical climate. It has wider adaptability and grows well where the temperature ranges between 20 and 35 °C. It responds well to a long period of sunlight (12 to 14 hours). High humidity (80–85 %) favours rapid cane elongation during the main growth period.

Sucrose is the primary product of plant photosynthesis and, therefore, common in food crops consumed regularly by humans and animals. Sugarcane also contains cyanogenic glucosides. These can be cleaved to produce hydrocyanic acid, a poison that acts by inhibiting cytochrome oxidase, thus preventing transfer of oxygen from the blood to the tissues. It is present in many plants, including sugarcane, where it is not at a dangerous level for humans.

Sugar not only enhances the flavours of food and intensifies its colour, but it also has other properties, e.g. it can be used as a preservative or as a substrate for fermentation, and it is also a source of energy. Consequently, it is a very useful commodity.
