摘要: 在大豆粉中分别添加0.5%和1.0%的农用尿素,以未添加农用尿素的大豆粉为对照组,通过干法单螺杆膨化机(EXT-155G)加工,检测膨化前后大豆粉样本的三聚氰胺残留含量,并采用SPSS 17.0对其膨化前后独立样本的三聚氰胺残留含量作均数t检验。随机试验结果显示:添加农用尿素的大豆粉膨化前后的三聚氰胺残留量差异极显著(P0.01)。可见,添加尿素的大豆粉在干法膨化工艺过程存有三聚氰胺背景残留增量。

Abstract: The single screw dry extruder(EXT-155G)processing experiments were carried out to investigate the urea's effect on the melamine residue in extruded soybean powder with three level of urea [0%(control group),0.5% and 1.0%] respectively.The melamine residue in the samples of different groups before and after extruded for the mean T test by SPSS 17.0.The randomized trial results showed that the melamine residue in the experiments(supply with urea)before and after extruded has significant difference(P0.01).In summary,it suggested that soybean powder with urea in the dry extrusion process can increase the melamine residue.
