Abstract

The problem of aflatoxin contamination of pistachios is one of the important research issues and one of the national and regional problems of this valuable product and pistachio exporting countries have always used this tactic against Iranian pistachios in order to compete in the international market. Many agricultural products are at risk of aflatoxin contamination and have been allowed in food due to health hazards. So in agriculture, we need controllers or processors of products, which are fast and cheap. The presence of fungi and the feeding of spores causes them to grow and produce more toxins in the product. The purpose of this study was to review the use of a spectroscopic method (surface-enhanced Raman SERS or FTIR) to detect the type and concentration of aflatoxin in pistachios using a simple method and rapid one-step extraction to discover and implement the method for analysis and Analysis is in place. The proposed SERS method can be used as a powerful tool to generate useful power for analysis with great accuracy and convenience to detect aflatoxins in many parts of the sample required for rapid analysis.
