摘　　要：蒸汽压片技术起源于美国,最初应用于反刍动物养殖中。蒸汽压片技术是一种谷物加工方法,谷物经过蒸汽调质、辊式压轧和干燥冷却等过程制成片状谷物,通过加工过程中的各种物理、化学作用,提高谷物中淀粉和其他化学成分的可消化性,增加营养物质与消化道消化液的接触面积,并在一定程度上改变其消化位点,从而增加动物对谷物的消化和吸收率。因此,蒸汽压片技术可以改善谷物的营养价值,提高动物对谷物的利用效率,减少饲料浪费和环境污染。作者综述了蒸汽压片技术的工艺流程、参数和评价指标,以及蒸汽压片处理对谷物营养成分的影响及其在畜禽生产中的应用。Steam-flaked technology originated in the United States,the initial application in ruminant production. Steam-flaked technology is a method of grain processing, which grain has been made into flake after a series of processing such as steam hardening and tempering, roller press rolling and cooling. By a variety of effect of physical and chemical in the process of processing,the digestibility of starch and other chemical composition was improved,the contact area of nutrients and digestive tract digestive juices was increased,and the digestive site was changed to a certain extend. Thus, it could increase the animal digestion and absorption rate of grain. As a consequence, the steam-flaked technology could improve feeding value of grain, increase the efficiency of animals used for grain and induce feed waste and environmental pollution. In the article, the technological process of steam-flaked, the influence of steam-flaked on grain nutrients and its application in livestock and poultry production have been reviewed.
