摘　　要：通过检测不同产地及品种花生蛋白质的抗原性,并分析其蛋白质结构特性。结果表明:“豫南阳鲁花8号”的抗原性最高,为2.270,"鲁济南四粒红"的抗原性最低,为0.804;花生蛋白质抗原性与二级结构中β-折叠呈极显著负相关,相关系数为-0.752(P<0.01),与β-转角呈极显著正相关,相关系数为0.750(P<0.01),与α-螺旋和粒径呈显著负相关,相关系数分别为-0.466、-0.482(P<0.05)。The antigenicity and structural characteristics of peanut proteins from different origins and va­rieties were analyzed.The results showed that the highest antigenicity of"Yu-Nanyang Luhua No.8"was 2.270,and the lowest antigenicity of"Lu-Jinan Silihong"was 0.804.The antigenicity of peanut protein was negatively correlated with p-folding in secondary structure with a correlation coefficient of-0.752(P<0.01),positively correlated withβ-tum with a correlation coefficient of 0.750(P<0.01),negatively correlated withα-helix and particle size,and the correlation coefficients were-0.466 and-0.482(P<0.05),respectively.
