高粱是一种古老的作物初次被驯化于非洲,并在公元前3000年左右推广到了世界各地。高粱是一种抗旱的谷类作物,生长在其它作物无法生存的半干旱气候条件下,在2002年世界高粱产量达到5450万公吨。美国高粱年产量可达1300～1500万公吨左右,其中30%～50%用于出口,在西方国家中用高粱喂养动物已非常普遍,大约世界高粱产量的40%被用于作为非洲和印度等国家人民的食物。在美国对于患有腹乳糜泻疾病无法适应面筋蛋白的人已经用白色食品级的杂交作物生产出运用于无小麦产品作为食用,不能食用小麦或其它谷类作物比如黑麦,大麦,他们提供了些刺激性小的面粉已成为用于制造无小麦食品的原料。当高粱缺乏面筋时,高粱粉便不能生产有黏性和弹性的生面团,因此蛋奶糊配方被用于制造高粱产品,包括面包威化饼干、面条和比萨饼皮,这些原来都是由面粉制成。研究表明,高粱系生产高质量食物,因此种植高粱将被用于改善提高食物质量,最近一些研究表明由于这种古老作物包括含有二十烷醇(policosanols)的多酚复合物和高粱蜡的高抗氧化水平,可能对健康有独特的益处,对于保护心血管的健康至关重要。尤其在把小麦作为主要食物的西方世界,对于给患有腹乳糜泻疾病的人们提供了健康稳定的主食是一个挑战。因此高粱这种古老的作物作为21世纪?

通过引入天冬酰胺酶和/或甜菊苷到曲奇配方中替代部分糖以抑制其生产过程中丙烯酰胺的生成,分析单独或同时添加这两种配料时曲奇面团的动态流变学特性、硬度和曲奇饼干的烘焙感官特性。结果表明:当单独添加天冬酰胺酶(1000 ASNU)时可降低曲奇样品中天冬酰胺含量(0.045mg/g)的67%,从而抑制95%丙烯酰胺的生成,且不会影响曲奇产品的烘焙特性。而天冬酰胺酶和甜菊苷同时添加时可抑制样品中96%丙烯酰胺的生成。动态流变学结果表明:引入天冬酰胺酶不会影响曲奇面团的流变学性质,而甜菊苷的加入会增加面团的弹性模量G'和黏性模量G〃,这是因为甜菊苷替代面团中糖成分后促进曲奇面团面筋网络的形成。但是,部分糖被取代后会改变曲奇的一些烘焙特性,如:水分含量增加,曲奇饼干颜色变淡,延展率和破碎力降低。感官分析结果表明:感官评定者不能接受45%和60%糖取代量的曲奇,但可以接受15%或30%糖取代量的曲奇。

采用天然抗氧化剂荞麦、孜然和黑种草籽抑制曲奇中丙烯酰胺的生成。研究这3种配料对面粉中丙烯酰胺前体的含量、面粉和曲奇抗氧化的特性、曲奇烘焙特性和丙烯酰胺含量的影响,结果表明:这3种配料组合都可以增加面粉中还原糖和天门冬酰胺的含量,也可以增加面粉和曲奇的抗氧化特性(包括总酚类物质、DPPH自由基清除能力和ABTS+.的抑制能力)。当所添加的天然抗氧化剂含量增加时,曲奇颜色变深,表现为更低的L*,a*和b*值;荞麦和孜然的引入会增加曲奇中的水分含量,而黑种草籽则相反。所有天然抗氧化剂组合都可以增加曲奇的延展率。未添加天然抗氧化剂的曲奇中丙烯酰胺的含量为361.2μg/kg,而单独添加15%荞麦、15%孜然和15%黑种草籽使得曲奇中丙烯酰胺的含量分别降低了20.2%、67.6%和75.9%。感官分析结果表明:富含天然抗氧化剂的曲奇都可以被人们所喜欢。
