Objective: To detect whether pesticide residues in vegetables and fruits exceed the standard by enzyme inhibition rate method.
After reagent preparation, sample extraction and detection, we can judge the quality of vegetables by the detection inhibition rate of the display screen. 0% & lt； Detection inhibition rate
2. Hang the white block detector
Objective: To check whether merchants use sodium formaldehyde sulfoxylate as food bleach in violation of regulations.
Add the soaking solution of the food sample into the colorimetric tube, and then add the chromogenic solution. By comparing with the color card, the content of sodium bicarbonate in food was determined. When the soaking solution is lavender or purplish red, the product quality is unqualified.
3. Nitrite detector
Usage: Check whether the pickled ingredients and meat are safe and whether the nitrite exceeds the standard.
Start the instrument, set the appropriate temperature, put the reference reagent cuvette and the cuvette containing the sample into the cuvette channel for detection, and the software will display the detection results after the detection.
4. Meat moisture detector
Objective: To quickly detect the moisture content of meat and judge whether it belongs to water-injected meat.
After the relevant settings are completed, just insert the probe electrode into the tested sample and press OK, and the same action will be repeated many times according to the set value. Finally, the instrument will display the measured moisture value.
5. Multifunctional food safety detector
Usage: One machine can perform multiple functions, quickly detect multiple indexes, and is suitable for various food safety detection occasions.
The machine can quickly detect the contents of dozens of toxic and harmful substances and additives such as sulfur dioxide, heavy metal lead and food urea according to relevant national standards, and can be used to detect ingredients such as vegetables, fruits, rice and flour products, aquatic products, meat products and pickles.
