【摘要】 谷物制品是人类膳食重要的组成部分,为人体提供所需的能量、蛋白质、B族维生素和矿物质。谷物制品种类繁多,主要包括米制品和面制品。谷物制品的主要成分是淀粉,并且所含的淀粉在加工过程中大多经历了糊化过程,这就导致谷物制品在储藏过程中易发生老化现象。老化后的谷物制品表现为失水干燥、质地硬化、风味丧失,其中馒头、面包易掉渣,面条、米线易断条,严重影响产品的货架期及食用品质。针对谷物制品易老化的问题,本文综述了谷物制品老化机理及影响因素的研究进展,包括淀粉回生、水分迁移与再分布,以及食品成分及环境条件对谷物制品老化的影响。同时对谷物制品老化调控机理进行了总结和分析,也对新型老化调控技术进行了展望。旨在对谷物制品的老化控制提供一定的参考,对我国谷物制品产业的发展提供一定的帮助。更多还原

【Abstract】 Cereal products are the important component of human s dietary,which provide the necessary energy,protein,vitamim B and mineral for people.There are many kinds of cereal products,mainly including rice products and flour products,such as bread,noodles and rice,rice noodles,etc.Starch is the main composition in cereal products,which are gelatinizated in the food processing processes,however,cereal products easily become retrogradated during storage.Cereal products would exhibit some phenomenons,which contained loss of water and dry,texture hardening and loss of flavor.Bread and steamed bread were easily to loss of crumb,and wheat noodles and rice noodles were easily to fracture.The retrogradation has a seriously negative influence on the warranty period and edible quality of cereal products.In view of the problem about cereal products retrogradation,the research progress on retrogradation mechanisms and factors of cereal products are reviewed in this paper,including starch retrogradation,moisture migration and redistribution,and effects of food ingredients and environmental conditions on the retrogradation of cereal products.At the same time,the mechanisms of the cereal products retrogradation controlling were summarized and analyzed,and the new retrogradation controlling technologies were prospected.This paper may provide the references of anti-retrogradation on cereal products,and may be helpful for the development of cereal products industry in China.更多还原
