Residues of Kekele in import and export meat and meat products
Test method liquid chromatography
1 Scope
This standard stipulates the sampling, sample preparation and liquid chromatographic determination methods for the detection of kekuol residues in meat and meat products for import and export.
This standard applies to the inspection of the residual amount of Kekele in pork and pork ham.
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 one bag from each piece as the original sample, the total amount of the original sample is not less than
2kg. Put it in a clean container, seal it, mark it, and send it to the laboratory in time.
If there is no small package in each piece, or there is a small package but the weight exceeds 2kg, you can use a sterilizer to extract a lot of pieces in the extracted package.
At 100g. After mixing, it was placed in a clean container as a mixture of original samples. The weight of the mixed original sample is not less than 2 kg. After the seal, the mark
Remember to send it to the laboratory in time.
2.4 Sample preparation
1kg was shrunk from the original sample taken, fully mashed and homogenized by a masher, and divided into two parts, which were respectively placed in a clean container as the original
Start sample. Seal and mark the mark. Samples should be protected from contamination or residue levels during sampling and sample preparation operations.
Variety.
2.5 Sample storage
The samples were stored frozen at -18 °C.
3 Determination method
3.1 Method summary
The sample was extracted with acetonitrile, and the extract was filtered, and the sodium sulfate solution was added thereto, followed by extraction with n-hexane. The n-hexane extract is concentrated,
After constant volume measurement, the high performance liquid chromatograph with UV detector was used for the determination by external standard method.
