摘 要: 从紫苜蓿叶中提取出的食用苜蓿叶蛋白(EALP)含有57.9%蛋白质和12.7%膳食纤维,是一种良好的食用蛋白新资源。EALP的氨基酸配比较合理,营养价值较好,但工艺特性较差。对面粉的添加量超过3%~4%时,会对面团流变学特性、面包焙烤品质与面条烹煮品质造成明显不良影响,因此通常的添加范围不超过3%~4%。当添加量增大时,需同时配合些活性面筋粉之类品质改良剂。 dible alfalfa leaf protein(EALP) extracted from Medicago Sativa contained 57.9%(wb.,etc.) protein and 12.7% dietary fibre,which was a good new resource of human edible protein. EALP was good in amino acid pattern but rather poor in technological properties.Above 3~4% of incorporation level,EALP would take obviously negative effects on dough rheological,bread baking and noodle cooking properties.The proper level incorporated into wheat flour was therefore limited within 3~4%.Some improvers such as vital gluten(VG) was needed when incorporation level increased.
