Food safety means that the planting, breeding, processing, packaging, storage, transportation, sales and consumption of food comply with the national compulsory standards and requirements, have no poisonous and harmful substances that may damage or threaten human health, meet the nutritional requirements and cause no acute, sub-acute or chronic harm to human health. Food safety is also a cross-disciplinary field which is specialized in ensuring food hygiene and food safety, reducing the hidden danger of disease and preventing food poisoning in the process of food processing, storage and sales, so food safety is very important.
Ø On-line foreign matter detection
During food processing, it is easy to be polluted by metal matters such as iron wires, cutter chips and other foreign matters such as ceramics, glass, rubber, etc. X-ray detection system can remove the products with foreign matters on the production line. The stay of food under the X-ray beam is extremely short. The highly developed X-ray detection technology can even meet the harsh requirements of organic food.
BEIJING HAMAMATSU PHOTON TECHNIQUE INC. (BHP) can provide X-ray imaging system products and glass shells, glass tubes for X-ray tubes..
Ø Detection of radioactive substances
Water, agricultural products and deep-processed food contaminated by radionuclides not only have radioactive hazards in the process of production, processing and circulation, but also have unthinkable consequences when being eaten by human beings. Therefore, the monitoring of radionuclide contamination in food products deserves concern.
BHP can provide scintillators, PMTs and scintillation detectors for detecting radioactive substances in food.
Ø ATP rapid detection
Adenosine triphosphate (ATP) exists in all animals and plants, bacteria, yeasts, molds and food residues. ATP is released by destroying the cell wall through ATP release liquid. When ATP binds to luciferin under the action of luciferase, it emits a kind of biological fluorescence, and the amount of fluorescence is proportional to the amount of ATP. The fluorescence is collected, amplified, converted and counted by the photocell. Finally, the relative amount of ATP is displayed by the monitor. So the relative situation of bacteria and food residues at the test site can be known.
HAMAMATSU PHOTON TECHNOLOGY(LANGFANG) CO.,LTD. (BHL) can provide portable ATP rapid tester with high precision and high stability optical signal detector .
Ø Immunochromatographic analysis
Immunochromatographic analysis is to fix a specific antibody to a certain zone of nitrocellulose membrane first. When one end of the dried nitrocellulose is immersed in the sample, the sample will move forward along the membrane due to capillary action. When it moves to the region where the antibody is fixed, the corresponding antigen in the sample is bound specifically to the antibody, and the specific change of the region is detected, so as to realize specific immunoassay. The technology is widely used in the detection of clenbuterol, melamine, drug residues, etc.
BHL can provide gold-labeled/fluorescent quantitative analyzers and instrument customized solutions, faster, portable and lower cost.
