罐头食品,除了一些肉类罐头(比如午餐肉)会添加亚硝酸钠作为防腐剂以外,其他的一般都不会添加多余的防腐剂
罐头是属于密封包装的食品,只要密封的好,内装食物在杀菌过后,细菌进不来,没必要添加防腐剂
除非是一些不正规的小厂房,密封技术不过关,或者杀菌条件不过关,这样的话,就会添加一些防腐剂来保证食品的质量
不过罐头只是方便食品,不能保证提供均衡的营养,所以不宜长期使用。

因为目前已经没有了防腐剂食品,所以请放心,虽然有特殊添加剂具有防腐作用,但是对身体影响不算大。但是还是建议不要经常喝听装或者汤类食品。因为汤类食品保质期短,不新鲜,而且是经过机器的制作,虽然机器经过高温消毒,但是毕竟是液体食物,细菌是靠液体繁殖和传播,所以哪怕有一点点水细菌都可以很快的繁殖,无菌生产并不是说一点细菌都没有,是很少,百分之零点零的比例,世界上那有没有细菌的东西?你说是把,然后细菌会存活在液体上,而且细菌的繁殖速度你也知道,那么这些液体食品经过一个月两个月的保存,那你想想细菌繁殖到什么地步了。还有牛奶也一样,为什么不用易拉罐就是因为易拉罐没有纸盒那么卫生。

还有,易拉化学效果生成其他物质。八宝粥放在里面时间长了你想想会怎么样?易拉罐表面更脏,容易吸附灰尘。适合寄生虫或者飞行虫类生活,比如小蜘蛛也会在易拉罐上织网。罐这些听装食品也很有卫生隐患,易拉罐是金属,对带有酸的物质敏感,并且发生。

不管别的罐装食品如何,但是我可以负责任的告诉你,八宝粥的生产工艺决定了它不需要防腐剂就可以达到24个月的保质期。凡是正规的八宝粥生产厂家,应该都具备这个能力,高温杀菌将近1小时,所有有害菌都被杀死,同时在罐装密封状态下可以保证长久的不变质。
作为曾经的食品研发员,负责任的告诉你,没有防腐剂,也不需要添加防腐剂,密封条件下的高温高压杀菌已经达到商业无菌的效果
明明是肯定会有防腐剂的,不然八宝粥属于食品,他为什么会在非真空的条件下储藏时间那么久。
当然有啊,这是毋庸置疑的,那么便宜不可能没有防腐剂
我觉得除了肉类的罐头食品会添加防腐剂。其他的一般都是不会随意添加防腐剂的。
