Sodium cyclamate, chemically named sodium cyclohexylsulfamate, has the molecular formula C₆H₁₂NNaO₃S·nH₂O (where n = 0 for the anhydrous form with a relative molecular mass of 201.22; n = 2 for the crystalline form with a relative molecular mass of 237.25). It is a representative of cyclamate - type sweeteners. It is a white needle - like, flaky crystal or crystalline powder with a melting point of 265℃. Its water solubility is ≥100g/L (20℃), and it is almost insoluble in ethanol, diethyl ether, benzene, and chloroform.

Characteristics

1. High sweetness: Its sweetness is about 30 - 50 times that of sucrose. A small amount of it is used per unit, enabling products to be sweetened at a relatively low cost.

2. Good stability: It is stable to heat, light, and air. It has a slight bitter taste after heating, and its decomposition temperature is about 280℃. Under normal usage conditions, it does not decompose under heat, acidic, and alkaline conditions, and is not prone to moisture absorption and deterioration. It is stable in the pH range of 2 - 10, making it suitable for a wide variety of products.

3. Sweetness characteristics: Its sweetness appears relatively slowly but lasts for a long time, and its sweetness is relatively pure. It can replace sucrose or be used in combination with sucrose.

4. Low - calorie value: It provides almost no calories and does not participate in metabolism, making it suitable for the sugar - control needs of people with diabetes and obesity.

Application Fields

1. Food industry: It is a commonly used sweetener in the food industry and can be used in frozen beverages (except edible ice), canned fruits, fermented bean curd products, biscuits, compound seasonings, beverage categories (except packaged drinking water), prepared wines, jelly, jams, preserved fruits, pickled vegetables, cooked beans, shelled cooked nuts and seeds, bread, pastries, preserved fruit categories, candied fruit categories, fruit cake categories, etc. It can replace sucrose without changing the product flavor. Moreover, it can enhance the flavor of food and prolong the duration of the taste sensation, especially having a better effect on fruit - flavored products.

2. Daily chemical industry: It is used in products such as cosmetics and toothpaste to adjust the product flavor.

3. Home seasoning: It can be used in home - cooking and other home - seasoning scenarios.

4. Pharmaceutical industry: It is used in the production of sugar - coated tablets, syrups, and other oral medications and oral solutions to improve the taste of medications and enhance patients' medication - taking experience.

5. Others: It can be made into sugar packets for use in hotels, guesthouses, tourism, and other places. It can also be used in feed to improve the palatability of feed
