How to quickly quantify the vomiting toxin in wheat flour

Flour products

Is an indispensable component of our daily diet

Wheat vomiting toxins frequently appear frequently during summer harvests

Therefore, it is especially important to control the vomiting toxins in wheat products at the source.

Why do you appear frequently in the summer harvest?

What is the vomiting toxin ?

Vomiting toxin, also known as deoxynivalenol (DON),

It is one of the most common mold (toxin) toxins that contaminate food and food.

When people ingest food contaminated with DON

What will happen?

In severe cases, damage to the hematopoietic system causes death! ! !

The experiment proves that

Foods containing toxins can cause human poisoning even when heated at high temperatures.

In 1998, vomiting toxins were classified as Category 3 carcinogens in an evaluation report published by the International Agency for Research on Cancer.

How does vomiting toxins occur?

Toxic strains, temperature, ventilation, humidity, sunshine and other factors are closely related to vomiting toxins. It is widely found in barley, wheat, corn and oats. Because the proportion of grain in the traditional Chinese eating habits is much higher than that in the West, the harm of vomiting toxins is more prominent.

Rapid quantitative detection of vomiting toxins in wheat and flour in Shanghai - -8min rapid quantification

Shanghai Feishen Bio is based on the world's leading fluorescence quantitative POCT technology platform . It is the first in China to introduce a vomiting toxin fluorescence quantitative test strip. This product can quickly and quantitatively detect the residual content of vomiting toxin in wheat and flour at 8 min . The treatment is simple (only 8min), the detection operation is simple, and the fluorescence immunoassay analyzer reading is adopted. The result is accurate and reliable, and can be printed on site. The accuracy is in accordance with the detection result of the HPLC method, and is suitable for various wheat and flour processing enterprises and testing institutions.

Result interpretation and output

The portable jade vomiting toxin detector is used to make the readings more accurate and objective, and avoid artificial misjudgment.

Mycotoxin detector

The test result will be presented on the liquid crystal display of the fluorescence reader. At the same time, the paper test report can be obtained by pressing the print button. In addition, after the WIFI data upload function of the instrument is turned on, the relevant data information will be automatically uploaded to the “Food Safety Traceability Management”. Cloud platform for easy traceability and quality management.
