【摘要】 为避免误食亚硝酸盐引起的食物中毒事件的发生,对食品用亚硝酸盐进行染色以警示。首先选择用于亚硝酸盐染色的色素,并对染色后的亚硝酸盐(以下简称染色盐)在日光直射、自然光照射、避光保存时的稳定性进行实验,按照尽量少用色素的原则确定亚硝酸盐染色时的色素添加比例;以最佳色素比例进行温度、pH值、食盐等因素对染色盐稳定性的影响实验。结果表明:以红曲色素对亚硝酸盐染色,在避光保存(色素比例1:10000)或自然放置(色素比例5:10000)的情况下,染色盐的颜色基本不受上述因素的影响。更多还原

【Abstract】 In order to avoid food poisoning for eating nitrite by mistake,Monascus pigment staining was used to provide a warning method for nitrite in food.Monascus pigments and sodium nitrite were homogeneously blended in three different ratios(1:10000,5:10000 and 10:10000,m/m),and the effects of direct sunlight,illumination light(in a place free from direct sunlight),darkness,temperature,pH and sodium chloride on the stability of the resulting staining products.The staining product with 1:10000 Monascus pigments/sodium nitrite ratio presented the best stability in the dark,and the storage condition for stabilizing the staining product with 5:10000 Monascus pigments/sodium nitrite ratio(m/m) best was free from direct sunlight.更多还原
