摘 要: 从紫苜蓿叶中提取的叶蛋白(EALP)含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的影响,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的品质改良剂。 Edible alfalfa leaf protein (EALP) extraccted from Medicago sativa contains 57 . 9% of protein and 12 . 7 % of dietary fibre, which is a new resource nf edible protein. EALP has proper amino acid proportioning and good nutritive value, but is rather poor in processing properties . Above 3 % -- 4 %of its incorporation level has taken obviously negative effects on dough rheologi- cal properties, bread baking and noodle cooking properties . The proper level incorporated into wheat flour is therefore limited within 3 % - 4 % Some improvers such as vital gluten ( VC) was needed when incorporat ion level increased ,
