Food Toxic Substance Detection
As the material basis for human survival, the quality and safety of food have a great impact on human health and safe reproduction. The safety of food also has a profound impact on the development of contemporary society and the economy. Therefore, it is necessary to test the quality and safety of food to effectively guarantee the quality and safety of food.
Sources of Food Toxicity
- There are many kinds of food poisoning, for example, vegetables and fruits are contaminated by pesticides and the environment, and heavy metals, nitrates, and nitrites are left after maturation.
- Due to the long-term use of a large number of pesticides, the content of nitrates, nitrites, and heavy metals in vegetables and fruits is very serious.
- At the same time, the production of toxic substances in raw materials will ultimately affect the safety of processed foods, in the food processing process, due to heat, moisture and other factors will also make food toxic substances, such as fried foods often produce carcinogenic acrylamide.
- In addition, food in the storage process is also more likely to produce toxic substances, such as aflatoxin in peanuts.
Our Solution
| ID | Project | Detail |
|---|---|---|
| 1 | Acrylamide | Acrylamide is widely distributed in all types of food processing at high temperatures and is widely recognized as a major carcinogenic metabolite. |
| 2 | Mycotoxin | Mycotoxins are a group of toxic secondary metabolites produced by fungi. They are widely contaminated with plant products such as crops, food, and feed. There are more than 300 known species, a significant proportion of which are highly carcinogenic and teratogenic. |
| 3 | Ochratoxin A (OTA) | OTA is a toxin produced by Aspergillus ochraceus and several Penicillium species that cause kidney damage in a variety of poultry and wildlife that consume feed contaminated with it. Dietary intake of high doses of OTA can cause liver damage as well as intestinal gangrene and hemorrhage. |
| 4 | Zearalenone (ZEN) | ZEN is a 2,4-dihydroxybenzoic acid lactone compound produced mainly by Fusarium that is estrogenically active and causes feminization in animals at dietary levels ≤1 mg/kg. Higher doses can interfere with normal fertilization, ovulation, fertilization, fetal development, and neonatal survival. |
| 5 | Deoxynivalenol (DON) | DON is a type of Fusarium toxin that is slowly produced in grain crops, mostly during cold, wet, and harvest seasons. DON is toxic to animals that eat it, and food poisoning leukocyte deficiency can occur after human consumption. |
| 6 | T-2 toxin | T-2 toxin is widely distributed in nature and is the main toxin that commonly contaminates field crops and stock grains. It is harmful to humans and animals. |
Our Platform
Currently, Lifeasible has a variety of methods for the determination of common toxins in food, including TLC, ELISA, UPLC-MS/MS, and others.
TLCPhysiological biochemical techniques as a more important food microbiological detection method, physiological biochemical techniques can show strong applicability in determining the metabolites of the bacteria, but also accurately reflect the status and number of strains of bacteria.
ELISAELISA is based on the principle of antibody-antigen reaction, although it has the characteristics of sensitive, rapid, and specific detection, and the minimum detection amount can theoretically reach 14 g/kg or less, but it is prone to false-positive results and has low precision, and can only be used as a rough screening method.
Ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS)We offer a UPLC-MS/MS method with the easy and accurate operation, high recovery, good precision, and reproducibility.
- The immunomagnetic bead isolation method
- Immunity assay reagent strips
- Immunoemulsion reagent
- Immunoenzymatic technique
- Immunochromatography
Lifeasible has developed a new food toxicant detection technology platform by combining highly active gold nanomaterials (AuNPs) and SERS technology for the detection of toxicants in food.
Cloud calculation-based inspectionWe collect the food inspection and testing big data of each inspection and testing organization gathered in the database, and fully utilize the characteristics of cloud computing platform such as high availability and high virtualization to dynamically schedule and allocate resources to meet the needs of accurate risk analysis and efficient data mining. Thus, we propose a cloud calculation-based risk analysis algorithm for big data of food inspection and testing of toxic and hazardous substances.
