摘　　要：目的研究儿茶素对面包贮藏品质的影响。方法将儿茶素(质量分数为0%、0.025%、0.05%、0.1%、0.2%、0.4%)添加到面团中,研究不同添加量儿茶素对面包的热性质、比容、感官质量、巯基、氧化稳定性、自由基清除能力、色泽、质构特性的影响。结果随着儿茶素添加量的提高,面包的比容先增大后减小;添加质量分数0.05%儿茶素的面包的比容最大(P<0.05)。在贮藏1~5 d内,面包的巯基含量、过氧化值和硫代巴比妥酸值随着儿茶素添加量的增加逐渐降低,DPPH自由基清除率和ABTS自由基清除率总体上逐渐升高。结论将儿茶素加入面包中起到了抗氧化作用,儿茶素可用于功能型面包的制作。The work aims to study the effect of catechin concentration on the storage quality of bread.The effects of different concentrations of catechin(0%,0.025%,0.05%,0.1%,0.2%,0.4%)on the thermal property,specific volume,sensory quality,sulfhydryl group,oxidation stability,free radical scavenging ability,color and texture of bread were investigated.With the increase of catechin content,the specific volume of bread first increased and then decreased.The specific volume of bread with 0.05%catechin was the largest(P<0.05).During the storage of 1-5 d,the sulfhydryl content,peroxide value and thiobarbiturate value of bread gradually decreased with the addition of catechin,while the DPPH free radical scavenging rate and the ABTS free radical scavenging rate gradually increased.The addition of catechin improved the antioxidant activity of the bread.Catechin can be used in functional breads.
