Abstract

Free asparagine concentration, which is the determining factor for acrylamide-forming potential in cereals, was measured in grain from wheat grown in field trials in the United Kingdom in 2011-2012 and 2012-2013. There were 25 varieties in 2012 and 59 in 2013, with eleven present in both trials. The trials were split-plot, with half of each plot supplied with sulphur and the other half not. The varietal means (mmol per kg) for free asparagine in the sulphur-fed wheat ranged from 1.521 to 2.687 in 2011-2012 and 0.708 to 11.29 in 2012-2013. Eight varieties were identified as having consistently low free asparagine concentration. There was a differential response of varieties to sulphur, and much higher levels of free asparagine in 2012-2013 versus 2011-2012. Given the short commercial lifespan of some wheat varieties, it is concluded that information on free asparagine concentration should be made available when a variety is launched.

摘要

游离天冬酰胺的含量是谷物中形成丙烯酰胺潜力的决定因素，对2011 - 2012年和2012 - 2013年在英国田间试验种植的小麦籽粒进行了测量。2012年有25个品种，2013年有59个品种，两次试验都种植了11个品种。试验采用裂区设计，每个地块的一半施硫，另一半不施硫。施硫小麦中游离天冬酰胺的品种均值（毫摩尔/千克）在2011 - 2012年为1.521至2.687，在2012 - 2013年为0.708至11.29。有8个品种被确定为游离天冬酰胺含量始终较低。各品种对硫的反应存在差异，2012 - 2013年游离天冬酰胺的含量比2011 - 2012年高得多。鉴于一些小麦品种的商业寿命较短，得出的结论是，在一个品种推出时应提供有关游离天冬酰胺含量的信息。
