Sweetener standard is a part of the reference substances used in food analysis, which is mainly used to analyze the type and content of sweeteners in food. As reference materials, the sweetener standards have high purity and can be either a single ingredient or a mixture. In the field of sweetener analysis, sweetener standards can be used in both quantitative and qualitative analysis, especially in quantitative analysis.
Generally, sweetener standards are used in liquid state to make standard curves, which is necessary in quantitative analysis. Commonly used sweetener standards include dulcoside A, isosteviol, rebaudioside B, cesulfame potassium, sucralose, aspartame, stevioside, sodium cyclamate and others.
Sweetener standards are widely used in many analytical methods including high performance liquid chromatography (HPLC), high performance liquid chromatography-mass spectrometry (HPLC-MS), gas chromatography (GC), gas chromatography-mass spectrometry (GC-MS) and others.
High performance liquid chromatography (HPLC): Sweetener standards are required in HPLC to quantitatively analyze the content of sweeteners in food. For example, based on sweetener standards, the content of sweeteners such as aspartame, sodium cyclamate, saccharin sodium, aspartame and stevia glycosides in liquor can be determined by high HPLC, which has the advantages of high selectivity, fast analysis speed and high accuracy.
High performance liquid chromatography-mass spectrometry (HPLC-MS): Sweetener standards are needed in HPLC-MS. The internal standard method can be used to detect aspartame in wine, which has the characteristics of low detection limit and high accuracy.
Others: Apart from the above two fields, sweetener standards also have important applications in other fields. For example, with sweetener standards, GC and GC-MS can be used for qualitative and quantitative analysis of sodium cyclamate in foods. In addition, standard substances can also be used in square-wave voltammetry to test the content of sweeteners in beverages.
