UNCERTAINTY ASSOCIATED WITH SAMPLING AND EFFECT OF SAMPLING PLAN IN AFLATOXIN ANALYSIS OF DRIED FIGS

摘要

Aflatoxin test procedure is a multi-stage process and generally consists of three steps; sampling, sample preparation and analytical steps. Because of the uncertainty associated with each step, the true aflatoxin concentration of a bulk dried fig lot can't be determined with 100% certainty. The sources of error in the aflatoxin test procedure should be determined so that the errors can be effectively reduced. Studies were developed to measure the variability and distribution among replicated sample aflatoxin test results taken from the same aflatoxin-contaminated lot of dried figs so that a model could be developed to evaluate the risk of misclassifying lots of aflatoxin sampling plan designs for dried figs.
