Acesulfame Potassium, commonly known as AK sugar, is a synthetic fourth-generation sweetener with a sweetness of about 130 times that of sucrose. 

It has the characteristics of good taste, no calorie, and no metabolism, no accumulation in the body, and stable physicochemical properties.

Acesulfame is stable to light and heat, and has a wide range of pH values. It is one of the most stable sweeteners in the world and is widely used in various food products, mainly to give sweetness to food products, but it does not cause violent blood sugar reactions.

Acesulfame was first discovered by Hoechst in Germany in 1967, and was first approved in Britain in 1983, with a sweetness of 200-250 times that of sucrose.

At the end of the 1990s, China formulated the industry standard for its products. With the continuous improvement of the domestic production level of acesulfame, it has been applied more and more widely in food processing and exported in a larger proportion.

Characteristics

Ensure honey has the following characteristics: ① High safety. It is non-toxic, without side effects, and is a grade A food additive. China approved potassium acetylsulfamate as a food additive in 1992, and its scope of use and limit is included in GB2760-1996. ②Superior performance. Potassium acetylsulfonate has good solubility in water, high stability to light, heat, acid, alkali and microorganisms, and does not absorb moisture in the air, so it has strong adaptability. ③Pure taste. Potassium acetylsulfamate has a quick sweetness in the mouth and is naturally refreshing. It is an ideal sweetener for sugar-free food in combination with aspartyl phenylalanine methyl ester, sorbitol, xylitol and so on.

Identification test

Solubility Soluble in water. Very slightly soluble in ethanol. Determined by OT-42 method.

Potassium test (burnt residue of 2g sample) Positive (IT-27).

UV Absorption Dissolve 10 mg of the specimen in 1000 ml of water; the maximum absorption peak of this solution is at 227 ± 2 nm (see GT-29).

Take 0.2 g of the sample and add 2 ml of acetic acid solution (TS-1) and 2 ml of water. add a few drops of 10% sodium hexanitric hypercobaltate solution to this solution and a yellow precipitate should be produced.

Content analysis

Accurately weigh 0.15g of the pre-dried specimen, dissolve it in 50.0ml of glacial acetic acid and titrate potentiometrically with 0.1mol/L perchloric acid; or add two drops of crystalline violet test solution (TS-74), titrate with 0.1mol/L perchloric acid to the blue-green endpoint and maintain it for 30s o Also make a blank test and correct the necessary error. Per mL, 0.1 mol/L perchloric acid is equivalent to 20.12 mg of potassium acetylsulfonate (C4H4NO4SK).

Toxicity

ADI 0 to 15 (FAO/WHO, 2001).

Safe for use in food (FDA, §172.800, 2000).

Limit of use
