摘　　要：为探究护色处理对鲜食黄糯玉米真空包装加工效果的影响,以黄糯619鲜食玉米为原料,以色差值△E、黄蓝值b^(*)值和感官评分为指标,通过单因素实验和正交试验,确定鲜食黄糯玉米真空包装加工中的最佳护色条件。结果表明:鲜食黄糯玉米的最佳护色条件:Vc浓度为5 g·L^(-1)(质量浓度)、EDTA-2Na浓度为0.25 g·L^(-1)(质量浓度)、护色时间为30 min,在此条件下真空包装加工后的鲜食黄糯玉米△E值为16.88、b*值为35.91、感官评分为93.1分,加工后的鲜食黄糯玉米籽粒呈金黄色,色泽均一明亮。综上,研究结果能够为鲜食黄糯玉米真空包装加工中的护色处理提供理论依据。In order to explore the influence of color protection treatment on the vacuum packaging processing effect of fresh yellow waxy corn,Huangnuo 619 fresh waxy corn was used as raw material,and color difference value△E,yellow and blue value b^(*)and sensory score were used as indexes,the optimal color protection conditions in vacuum packaging of fresh yellow waxy corn were determined by single factor experiment and orthogonal experiment.The results indicated that the optimal color protection conditions for fresh yellow waxy corn were as follows:the concentration of Vc was 5 g·L^(-1)(mass concentration),the concentration of EDTA-2Na was 0.25 g·L^(-1)(mass concentration),and the color protection time was 30 min.Under these conditions,the△E value,b^(*)value and sensory score of fresh yellow waxy corn after vacuum packaging processing were 16.88,35.91 and 93.1 points,respectively.The processed corn grains were golden yellow,and the color was uniform and bright.The experimental results can provide theoretical basis for color protection in vacuum packaging processing of fresh yellow waxy corn.
