亚硝酸盐作为国家允许的食品添加剂广泛存在食物中,但其过量会对人体产生严重危害,为减少亚硝酸盐对人体的危害需对其进行深入研究。作者从物理、单一成分与食物提取液3个方面描述亚硝酸盐的清除方法,对亚硝酸盐的清除问题提出进一步的思考,为其清除问题提供新的课题,为百姓健康生活提供科学的应用研究。 Nitrite, as a food additive permitted by the state, is widely present in food. However, excessive amount of nitrite causes serious harm to the human body. Nitrite should be further studied in order to reduce its harm to human body. The author describes the methods of removing nitrite from three aspects of physics, single component and food extract, puts forward further thinking on the removal of nitrite, provides new problems for its removal, and provides scientific application for people’s healthy life. the study.
