Effects of Storage Conditions on Aflatoxin Contamination of Platycladi Seed and Detoxification Methods
摘要
Abstract
Objective:In order to understand the effects of different storage conditions on aflatoxin contamination of platycladi seed and the detoxification effect of different washing methods,provide references for developing reasonable storage conditions and detoxification techniques for platycladi seed. Methods:The contents of aflatoxins on 10 batches of platycladi seed were detected by HPLC.The storage experiment of platycladi seed was designed for two temperatures and two packages, and the content of aflatoxin B1(AFB1)and aflatoxin B1+B2+G1+G2(AFs)were analyzed after storage.Platycladi seed were washed by ethanol or water to remove the contaminated aflatoxin. Results:Aflatoxins were found on 9 batches of platycladi seed,of which 5 batches exceeded the maximum level permitted by 2015 Chinese pharmacopoeia.In storage experiment, AFB1 and AFs contaminated on platycladi seed were increased with time at 10 ℃ and 25 ℃.After 2 months of storage,AFB1 was increased up to 8.3 times than pre-storage,while AFs was increased up to 7.8 times.Compared with plastic bags package, aflatoxin contaminations on platycladi seed were not decreased obviously in vacuum package.The removal rates of AFB1 and AFs on platycladi seed were over 90% after ethanol washing,while they were over 87% when washed by water. Conclusion:The storage period of platycladi seed in plastic bag and vacuum package should not exceed 1 month at 10 ℃ and 25 ℃.Water washing and ethanol washing could partially remove aflatoxins from platycladi seed.关键词
