Embodiment Construction

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0022] see figure 1 , the present invention provides a technical solution: a method for traceability risk assessment of aflatoxin in oil crops, the main steps of the method are as follows:

[0023] S1: Research on the origin of oil crops: investigate the planting environment of oil crops in the origin of grain and oil crops, and obtain environmental samples of the origin of oil crops;

[0024] S2: Sample pretreatment: Combined with the investigation of the st...

Abstract

The invention discloses a traceability risk assessment method for aflatoxin in oil crops in the technical field of food safety. The method comprises the following main steps of: S1: carrying out original research on grain and oil crops; S2: carrying out sample pretreatment; S3: carrying out sample detection and data acquisition; S4: carrying out data analysis and result output; S5: establishing aflatoxin exposure assessment indicators; S6: establishing an aflatoxin exposure assessment model; and S7: controlling the product storage environment and storage time of plant edible oil. According tothe method, a liquid quality-mass spectrometry technique is used to determine the content of aflatoxin; the sample pretreatment process is simplified, so that the detection efficiency is improved; thecontent of aflatoxin daily ingested by human body is fitted to establish the aflatoxin exposure assessment model; and the content of aflatoxin is controlled from the planting, processing and productstorage links of oil crops, thereby reducing the daily ingestion of the human body and improving the safety of grain and oil crops.

Description

technical field [0001] The invention discloses a traceability risk assessment method for aflatoxins in oil crops, specifically in the technical field of food safety. Background technique [0002] Aflatoxin is a mycotoxin produced by Aspergillus parasitica, Aspergillus flavus and Aspergillus model under suitable humidity and temperature conditions. It is highly pathogenic and carcinogenic to humans and animals. Long-term small-dose intake of humans and animals can cause genetic and chromosomal mutation, embryonic abnormality, gastric cancer and other cancers, and induce primary liver cancer, and a large intake at one time can cause acute poisoning and even death. The toxicity is even much higher than that of organic pesticides, arsenic and cyanide. Among them, AFB1 is the most toxic and is the most toxic carcinogenic mycotoxin currently known. [0003] All countries in the world have established relevant limit standards for aflatoxins in imported agricultural products. Acc...
