Food formaldehyde hazards, food safety detector to detect
The harm of food formaldehyde is mainly manifested in the following aspects:
Irritation of the eyes, nose and throat, causing symptoms such as tearing and coughing.
It has an anesthetic effect on the central nervous system and can cause symptoms such as dizziness and drowsiness.
It has a strong irritating effect on the mucous membranes and can cause acute edema.
It has carcinogenic effects, formaldehyde can cause nasopharyngeal carcinoma and leukemia.
In order to ensure food safety, a food safety detector can be used to detect formaldehyde content in food. The food safety detector adopts high-precision imported sensors, which can instantaneously detect the existence of oxygen, combustible gas and toxic gases, and can choose diffusion or pumping type for sampling according to needs, and sound and light alarm prompts. The detection principle is that under specific conditions, formaldehyde is condensed with AHMT (4-amino-3-azine-5-mercapto-1,2,4-triammoheta), and then oxidized to form a purple-red compound, whose color is proportional to the formaldehyde content, and the concentration of formaldehyde in the sample to be measured is automatically calculated and printed by measuring the absorbance of the compound.
Therefore, the use of food safety detectors can effectively detect the formaldehyde content in food and ensure food safety.
