Sugar an important food also commonly known as sucrose is white crystalline substance, tastes sweet, a carbohydrate and 100% soluble in water. Sugar (Sucrose) is a natural combination of fructose and glucose. It is very stable product.
Sugars are a class of carbohydrates and thus one source of food energy. Carbohydrates can be divided into 3 different groups, namely: sugars; oligosaccharides and polysaccharides. Sugars can be further divided into 3 classes: monosaccharides; disaccharides and polyols.
Sugar is an important source of food energy. During digestion, all food carbohydrates (starches and sugars) break down into single molecule sugars. These sugars are absorbed from the intestine into the blood stream and travel to the cells, where they are used to provide energy for cellular functions. In parts of the world where people suffer from energy malnutrition and are undernourished, sugar is valued as an inexpensive source of energy to support human activities.
Table sugar can be used to make oral rehydration solution (ORS), which can help prevent dehydration in children who have infantile diarrhoea or vomiting in developing countries. The effective use of ORS saves millions of lives around the world each year. Although recipes for ORS vary from country to country, one widely used recipe is made up of 1 litre of water, 8 teaspoons sugar and ½ teaspoon of salt.
