The Research of Impact Factor of Aflatoxins in Oil-Tea Camellia Seed and Oil-Tea Camellia Seed Cake

Abstract

Through sampling from production enterprise, and testing methods design, the risk of aflatoxin contamination of Camellia oleifera seed was explored. It was proved that the chance of aflatoxin contamination is very small, for mainly processing happened in wintry and spring. After 7 days, 14 and 21 days artificial inoculation, the aflatoxin B1 in the cake was 1.7, 3.6 and 9.9 μg/kg, respectively, while the quality in camellia benevolence was 2.6, 1.8 μg/kg and below the detection limit 0.2 μg/kg. The results explained that Camellia oleifera seed can be untainted by aflatoxin in hot and humid climate conditions. The study answered the question whether the Camellia oleifera seed could be contaminated by aflatoxin, which wa an unresolved problem for a long-term. Also the conclusion was a warning for the safety of storage and production of Camellia oleifera seed in high temperature seasons.
