Sichuan Pepper Numbness Tester

Instrument Introduction

The sichuan pepper numbness tester adopts electrochemical measurement method, which can quickly and conveniently detect the content of natural Sichuan pepper extract in various Sichuan pepper and Sichuan pepper products. It is suitable for rapid detection of dried Sichuan pepper, Sichuan pepper oil, Sichuan pepper powder and other Sichuan pepper and its products.

Instrument Principle

The sichuan pepper numbness tester uses disposable three electrode plates to enrich capsaicin on the surface of the working electrode under the action of potential, and then gains and loses electrons under the working voltage, resulting in oxidation-reduction reactions. At this time, the current signal shows the corresponding oxidation-reduction peak on the display, and the content of Sichuan pepper amide is quantitatively analyzed based on the magnitude of the peak current.

The numbness of Sichuan pepper and Sichuan pepper products is mainly determined by the content of Sichuan pepper amide in Sichuan pepper. Zanthoxylum bungeanum is the main source of numbing taste in food, and it is directly related to the degree of numbing in food. The higher the content of Sichuan peppercorn amide, the greater the degree of numbness, and the corresponding food becomes more numbing.

Zanthoxylum bungeanum is the main component of Sichuan pepper with a numbing taste, containing various amide components such as hydroxyl - α - capsaicin, hydroxyl - β - capsaicin, hydroxyl - γ - capsaicin, and hydroxyl - ε - capsaicin. Among them, hydroxyl - α - capsaicin has the highest content, and the total content of Zanthoxylum bungeanum amide substances can be obtained by measuring hydroxyl - α - capsaicin. The unit of measurement for the content of hydroxyl - α - coumarin is mg/g.

At present, the numbing degree of Sichuan pepper oil is about 1-20mg/g, while the numbing degree of dried Sichuan pepper, fresh Sichuan pepper, and Sichuan pepper powder is about 5-100mg/g.
