摘要
利用DSE-25型双螺杆挤出机对亚麻籽粕进行挤压膨化质量研究。结果表明,挤压膨化过程中亚麻籽粕的理化性质发生了改变。在高温、高压、高剪切力环境下,蛋白质变性,总膳食纤维部分降解,有毒成分生氰糖苷被消除,氨基酸和可溶性膳食纤维含量增加,游离脂肪和水分含量减少,淀粉发生糊化裂解,组织结构疏松均匀,水溶性指数升高,吸水性指数下降。
The extrusion quality of flaxseed meal was studied with Brabender DSE-25 Twin-Screw Extruder. The results showed that physicochemical characteristics of flaxseed meal were changed during extrusion processing. Under the conditions of high temperature and high pressure and high shear force, proteins were denatured and total dietary fibers were broken down in part, while cyanogenic glucoside as one poisonous matter was removed. Meanwhile, the contents of amino acid and soluble dietary fiber were increased whereas fat and moisture were decreased. The starch was gelatinized and degraded, the texture became loose and homogenous. Meanwhile the water solubility increased and the water absorption level decreased.
