Description Saccharin sodium is a type of artificial or nonnutritive sweetener. It is 200 to 700 times sweeter than sucrose but has a bitter aftertaste. Saccharin and its salts do not occur naturally. Saccharin sodium is used in the production of various foods and pharmaceutical products including soft drinks, candy, biscuits, jams, chewing gum, tinned fruit, medicine and toothpaste.
Chemical Properties Saccharin is a crystalline solid with a sweet taste (500 times sweeter than sugar). It is commercially available in three forms : acid saccharin , sodium saccharin , and calcium saccharin . These forms have been variously determined to be 200-800 times sweeter than sucrose , depending on the saccharin concentration. Saccharine sodium salt has no odor, but has an intensly sweet taste. Aqueous solution is neutral or alkaline to litmus, but not alkaline to phenolphthalein. Effloresces in dry air.
Sodium saccharin
Sodium saccharin is widely used in food as a sweetener. There is evidence that sweet taste receptors of animals (pigs and bovines) also respond to saccharin (Hellekant et al., 1994; Moran et al., 2010).
Sodium saccharin is intended to be used in feed, premixtures and water for drinking for piglets (suckling and weaned piglets), pigs for fattening and calves for rearing up to 4 months and for calves for fattening up to 6 months, with levels up to 150 mg/kg of complete feedingstuffs and water for drinking.
Saccharin Saccharin is the oldest artificial sweetener, and was discovered in 1879. The compound is prepared through reacting methyl anthranilate with nitrous acid sulfur dioxide, chlorine, and ammonia. It is about 300 times sweeter than sucrose and is considered to be one of the most important and widely used sweeteners worldwide.
Saccharin is a water-soluble acid with a pKa of 1.8. Its absorption is increased in animal species with lower stomach pH, such as rabbits and humans, relative to other mammals with higher stomach pHs such as rats. Other forms of saccharin that are consumed include: calcium saccharin, potassium saccharin, and acid saccharin. Sodium saccharin is used most often due to its greater palatability.
Saccharin, in addition to being used as a table-top sweetener, is commonly used in soft drinks, baked foods, jams, canned fruit, candy, dessert toppings, and chewing gum. Since saccharin’s sweetening power is not reduced when heated, it is an excellent candidate as an additive in low-calorie and sugar-free products.
Uses Sodium saccharin is the salt most frequently used in formulating soluble forms of this sweetening agent. It can be used in toothpaste, mouthwash, diet soft drinks, syrups, baked goods, ice cream, and other sweet foods and drinks. While it is certainly most famously used in food products, sodium saccharin is also used in the chemical and agricultural industries as an aid in the production of herbicides and pesticides. It is also used as part of a solution used to coat metals, such as gold and nickel.
Major application of Sodium saccharine is the food industry as an additive in different products. It is used as a low calorie sweetener and stabilizer in a variety of food and drinks. In bakeries it is used to sweeten baked goods, breads, cookies and muffins. Due to its rapidly dissolving nature in water, it is used as an artificial sweetener in carbonated beverages and sodas.
Chemical Synthesis Saccharin is chemically synthesised. The manufacturing process described by the applicant uses either phthalic anhydride or methyl anthranilate as starting material. Methyl anthranilate is diazotized to form 2-carbomethoxybenzene-diazonium chloride. Sulfonation followed by oxidation yields 2-carbomethoxybenzenesulfonyl chloride. Amidation of the sulfonylchloride followed by acidification will form insoluble acid saccharin. Subsequent addition of sodium hydroxide produces the soluble saccharin sodium.
