1、不同大豆品种加工北豆腐的适用性研究刘香英，康立宁：田志刚，南喜平，代永刚(吉林省农业科学院农产品加工研究中心长春130033)摘要选用來自黑龙江、吉林.辽宇及内蒙古自治区的31个大豆栽培品种，进行北豆腐加工。对大豆品种原料理化指标.豆腐得率和质构特性指标进行测定、分析，并对不同大豆品种的豆腐加工适用性进行评价。结果表明：不同大豆品种间的蛋口质、脂肪、植酸及大豆球蛋0US和7S含議有着较大差别，引起不同大豆品种制作北豆腐的得率的差别。大豆品种籽粒品质与豆腐品质指标Z间的相关性表明：脂肪含量与蛋白含量.干豆腐得率与保水性、硬度与粘聚性、换度与回复性・硬度与黏附性、表观弹性率与保水性、
2、11S与7S、表观破断应力与保水性、11S与弹性等呈极显著或显著负相关；破度与咀嚼度、弹性与咀嚼度、粘聚性与冋复性、粘聚性与黏附性、卩11嚼度与表观弹性率、冋复性与黏附性、硬度与表观弹性率、蛋白质与干豆腐得率以及植酸与表观弹性率等均呈极显著或显著止相关。就所选取的31个人豆品种而言，黑河49、铁丰37、东农48、辽豆21、合丰43、垦丰17、哈北46和蒙豆16更适合于北豆腐加工。关键词人豆品种；豆腐凝胶；质构特性；相关性AdaptabilityofDifferentSoybeanVarietiestoBei-TofuProcessingLIUXiang-Ying,KANGLi-N
