AI Technical Summary
Existing technologies lack a suitable detection method for ochratoxin B in substances that are both food and medicine. Furthermore, traditional pretreatment methods are complex, costly, and unsuitable for large-scale sample testing, making it difficult to achieve effective extraction and quantitative analysis of OTB toxins.
The QuEChERS purification ultra-high performance liquid chromatography method is used, which includes sample pretreatment, QuEChERS salting out, and QuEChERS purification steps. Combined with ultra-high performance liquid chromatography-fluorescence detector, a variety of medicinal and edible substances are purified and detected by using a specific ratio of purifying agent.
It achieves highly sensitive detection of ochratoxin B in food and medicine substances, simplifies the pretreatment process, reduces costs, is suitable for large batches of samples, and has detection and quantitation limits lower than national standards, making it widely applicable.
