Rapid quantitative detection of ochratoxin A in wine - accurate quantification in -8 min

I. Overview of ochratoxin
According to the data, Ochratoxin A is a toxic fungal metabolite with high chemical stability and thermal stability. Ochratoxin is a group of structurally similar toxins produced by fungi such as Penicillium sp., Aspergillus oryzae and Aspergillus niger. It has the highest toxicity, the closest relationship to human health, and the most widespread pollution to crops. Ochratoxin A has strong hepatotoxicity and renal toxicity and is teratogenic, mutagenic and carcinogenic. Ochratoxin A is widely distributed in nature, grain, coffee, tea and other crops and foods, and is one of the major pollutants in the diet of some European countries.
Second, the national residue limit standard for ochratoxin A in wine
From September 17th, China implemented a new standard for ochratoxin A in wine, which extended to the wine field for the first time.
After the implementation of the new standard, the ochratoxin A contained in domestic and imported wines sold in the Chinese market will not exceed 2 μg/kg, which is consistent with EU standards. Given the irreversible damage this kidney can cause to the kidneys and liver, the EU is demanding more stringent regulatory procedures and adopted it 10 years ago.
Third, the limit of ochratoxin A in other countries
At present, there are more than 40 countries in the world that regulate the limits of ochratoxin A in food and its products, fruit wine, dried fruit and infant food. In addition, in the European Union in 2005, wines and wines or grapes used for beverage production were limited to 2.0 μg/kg; in grape juice and other beverages, the juice content was 2.0 μg/kg. The International Organization of Wine and Wine (OIV) sets the limit for OTA in wine to 2 μg/kg.
Ochratoxin A is usually present on the skin of grape fruit infected with fungi. Winemakers can reduce the risk of ochratoxin A contamination during winemaking by limiting the contact of infected fruit skin with wine and strong clarification techniques.
