Residues of Zearalenol in Import and Export Animal-derived Foods
High performance liquid chromatography-mass spectrometry/mass spectrometry
1 Scope
This standard specifies sampling, sample preparation and high performance liquid chromatography-mass spectrometry/mass spectrometry for the determination of zearalenol residues in animal-derived foods.
Test method.
This standard applies to the examination of zearalenol residues in liver, kidney and muscle of animal tissues.
2 Sampling and sample preparation
2.1 Inspection lot
No more than 2,500 pieces for an inspection lot.
Goods in the same inspection lot should have the same characteristics, such as packaging, marking, origin, specifications and grades.
2.2 Number of samples
The number of samples is shown in Table 1.
Table 1 is a unit
Minimum number of samples in batch
1~25 1
26~100 5
101～250 10
251~500 15
501~1000 17
1001～2500 20
2.3 Sampling method
The number of samples according to 2.2 is randomly selected and opened one by one. Take at least one bag from each piece as the original sample. If there is no small in each piece
Packed or small package, but the quality of each package is more than 2kg, you can use a sterilization tool to cut not less than 500g from each piece, after mixing
The original sample was mixed in a clean container. Mix the original sample with a total medium quality of not less than 2kg. After sealing, mark the mark and deliver it in time.
laboratory.
2.4 Sample preparation
Take a representative sample from the mixed original sample, mix well, and divide it to not less than 500g by the quarter method, and divide it into two.
Share. After homogenization, it is placed in a clean container as a sample, sealed and marked.
2.5 Sample storage
The sample was stored frozen at -18 °C.
3 Determination method
3.1 Method summary
After the homogenate tissue sample was hydrolyzed by glucuronidase, the zearalenol was extracted successively with diethyl ether and sodium hydroxide solution. Sodium hydroxide
The solution was neutralized and purified by a C18 solid phase extraction column. The methanol eluent was evaporated and determined for high performance liquid chromatography-mass spectrometry/mass spectrometry.
Standard method of quantification.
