Pepper numbing degree detector

The pepper numbing degree detector is an instrument used to measure the content of pepper amide (or pepper-numbing flavor), the main component that causes a numbing taste in pepper or pepper products (such as pepper oil). The numbing taste of pepper is caused by the unsaturated fatty acid amide compounds, especially pepper numbing (such as hydroxy-alpha-sanshool) activating specific nerve receptors in the mouth. Applying the numbing degree detector can ensure food quality control, compliance with condiment standards, and the accuracy of scientific research.

This product and method use spectrophotometric detection technology to react chemical reagents with pepper-numbing substances and then determine the content of pepper amide by color change and absorbance, which is used for quantitative analysis of the numbing degree of pepper and its products.

Instrument features

1. It uses a high-resolution (1024*768) dot matrix 7-inch color touch LCD with a friendly and simple operation interface.

2. The instrument supports a cloud storage function, which greatly facilitates the customer's application scenario.

3. The instrument uses a "blazed holographic grating" high-resolution C-T monochromator and a 24-bit high-precision AD chip from the American AD company, making the economical instrument have low stray light (less than 0.1T%), high precision, and high stability (0.002A) that only high-end instruments have.

4. The instrument has a strong storage capacity, which can store 2000 data and 96 working curves, which greatly facilitates customer use.

5. The instrument is equipped with a USB interface, a WIFI module, and a Bluetooth module. Wireless Bluetooth printing can be realized; it can be optionally connected to Yokelab computer software to quickly manage spectral data and facilitate data processing; it can be directly exported through a U disk, and the exported data can be directly opened and edited by EXCEL, which greatly facilitates customer application.

6. Supports fast scanning, fast wavelength movement speed, the fastest can reach 3000nm/min; automatic wavelength setting, automatic light switching setting, after connecting to the computer software, it can realize wavelength scanning, dynamic determination, quantitative determination, nucleic acid determination, wavelength superposition, integral derivative and other advanced functions.
