Parameters
柠檬酸(CA),又名枸橼酸,分子式为C₆H₈O₇,是一种重要的有机酸,为无色晶体,无臭,有很强的酸味,易溶于水,是天然防腐剂和食品添加剂。
注意事项
柠檬酸为食用酸类,可增强体内正常代谢,适当的剂量对人体无害。在某些食品中加入柠檬酸后口感好,并可促进食欲,在中国允许果酱、饮料、罐头和糖果中使用柠檬酸。虽然柠檬酸对人体无直接危害,但它可以促进体内钙的排泄和沉积,如长期食用含柠檬酸的食品,有可能导致低钙血症,并且会增加患十二指肠癌的几率。
基于柠檬酸对钙的代谢可产生的影响,经常食用罐头、饮料、果酱、酸味糖果的人们,特别是孩子,要注意补钙,多喝牛奶、鱼头、鱼骨汤、吃些小虾皮等,以免导致血钙不足而影响健康,胃溃疡、胃酸过多、龋齿和糖尿病患者不宜经常食用柠檬酸。柠檬酸不能加在纯奶里, 否则会引起纯奶凝固。乳制品行业常把柠檬酸配成10%左右的溶液加入低浓度的牛奶溶液中,加入时应快速的搅拌。
贮藏条件
应贮藏于气密容器内,置阴凉干燥处保存。
