Abstract

The invention discloses a paralytic shellfish poisoning (PSP) standard sample and a preparation method and an application thereof. Positive shellfish raw materials of PSP are initially frozen and dried after being acidized and homogenized to obtain a crude sample, and then the crude sample is frozen and dried once again after being ground and sieved to obtain the product in the invention with good uniformity and stability. The standard sample can be used for capability assurance activities of PSP test items in labs, for PSP qualitative and quantitative detection and for verification of a detection method, correction of a tester and quality control and examination of test results. The invention has low raw material cost and simple preparation method, and the obtained standard sample is a material standard sample, is even and stable and easy for storage, and is beneficial for effective monitoring on shellfish poisoning.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and relates to a shellfish toxin standard sample and its preparation method and application, in particular to a paralytic shellfish toxin standard sample and its preparation method and application. Background technique

[0002] In recent years, shellfish toxins have become an important public health problem. Many countries have controlled the limits of shellfish toxins in food. WHO has also issued a draft on the prevention of shellfish toxins and the protection of public health. my country is a major producer and exporter of shellfish in the marine economy, with an annual output of about 11 million tons of shellfish, accounting for 70% of the world's total. In the past 10 years, due to industrial pollution and other reasons, red tides have occurred frequently in my country's coastal waters, which has seriously affected the development of marine aquaculture and export trade. Since the incident of she...
