Description

Abstract: To increase awareness of the important of aflatoxin problem in peanut, study on seed quality and aflatoxin contamination in imported and local raw peanuts were undertaken to find out the chemical composition and aflatoxin contamination. Survey and collection of imported raw peanuts were undertaken from various parts of Thailand during January to December, 2000. Peanut seed moisture Content, chemical analysis for oil, protein, composition of fatty acid and peroxide value were determined. Aflatoxin contamination was analyzed by ELISA procedure. Consumer test of peanut products were done only in peanut lots of which the aflatoxin contamination was lower than 20 ppb. More than fifty percent of imported and local production peanuts were aflatoxin contamination at the level of higher than 20 ppb. Chemical composition and peroxide value of imported and local production peanuts were not different. Result from the consumer test revealed that the local large-seeded peanut variety KU 50 was more favorable than imported peanuts. Poster.
