Portable spiciness detector

Instrument Introduction

The handheld spiciness detector uses electrochemical measurement method to quickly and conveniently detect the level of natural capsaicin in various peppers and pepper products. It is suitable for rapid detection of natural peppers such as dried peppers, fresh peppers, and pepper powder and their products.

Instrument Principle

The spiciness detector uses a disposable three-electrode sheet. Under the action of potential, capsaicin is enriched on the surface of the working electrode, and then gains and loses electrons under the working voltage, and an oxidation-reduction reaction occurs. At this time, the current signal presents a corresponding oxidation-reduction peak on the display, and the capsaicin content is quantitatively analyzed according to the size of the peak current.

The spiciness of peppers and pepper products is mainly determined by the content of capsaicinoids in peppers. Capsaicinoids are the main source of food spiciness, which has a direct relationship with the spiciness of food. The higher the capsaicin content, the greater the spiciness value, and the corresponding food is spicier.

Capsaicinoids mainly include capsaicin and dihydrocapsaicin. Capsaicin and dihydrocapsaicin account for about 90% of the total amount of capsaicinoids. The total content of capsaicinoids can be obtained by measuring capsaicin and dihydrocapsaicin.

The unit of capsaicinoid content is mg/kg, and the unit of spiciness is Scoville index, expressed in SHU. The spiciness of pure capsaicin is 16 million SHU. The conversion relationship between capsaicin and spiciness is 1mg/kg capsaicin = 16SHU spiciness.

The hottest pepper at present is Carolina Reaper pepper, with a spiciness between 1.5 million and 2.2 million SHU; the spiciness of ordinary dried peppers is generally between 30,000 and 150,000 SHU, most of which are high-spiciness peppers; the spiciness of screw peppers is usually between 5,000 and 20,000 SHU; the spiciness of sweet peppers is almost zero and does not contain capsaicin.
