中文摘要:

        本文研究了不同温度、干燥时间和SAP-玉米比例等条件下,高吸水性树脂(SAP)干燥玉米和控制黄曲霉毒素污染的能力。温度和干燥时间对黄曲霉毒素的形成有显著影响。SAP-玉米比例在1:1到1:5之间时,干燥到最佳含水率13%后玉米均未受或几乎未受黄曲霉毒素污染,然而当比例为1:10到1:20之间时,由于含水率和干燥时间整体较高导致难以较好地控制黄曲霉毒素污染。研究结果表明,温度、SAP变化频率、干燥时间和SAP-玉米比例会影响干燥速率和黄曲霉毒素污染状况。另外,SAP具有良好的谷物干燥能力,是一种可以用于解决黄曲霉毒素污染的、可反复使用的解决方案,尤其是对于发展中国家和资源缺乏的地区而言。


外文摘要:

        The ability of superabsorbent polymers (SAP) in drying maize and controlling aflatoxin contamination was studied under different temperatures, drying times and SAP-to-maize ratios. Temperature and drying time showed significant influence on the aflatoxin formation. SAP-to-maize ratios between 1:1 and 1:5 showed little or no aflatoxin contamination after drying to the optimal moisture content (MC) of 13 %, while for ratios 1:10 and 1:20, aflatoxin contamination was not well controlled due to the overall higher MC and drying time, which made these ratios unsuitable for the drying process. Results clearly show that temperature, frequency of SAP change, drying time and SAP-to-maize ratio influenced the drying rate and aflatoxin contamination. Furthermore, it was shown that SAP had good potential for grain drying and can be used iteratively, which can make this system an optimal solution to reduce aflatoxin contamination in maize, particular for developing countries and resource-lacking areas.
