槽头肉成为央视315主角时，另一个顶流肉食也是祸从天降：淀粉肠塌房成了中文社交媒体热点。
有趣的是，没过几天，淀粉肠似乎要被一些科普大V们拯救了，而这一切的焦点都在
鸡骨泥。
淀粉肠被质疑是因为央广网一篇报道称一些淀粉肠用骨泥制作，在该报道中，记者询问得知骨泥用于做宠物食品，不适合人吃。而这两天，一些科普辟谣文章则称鸡骨泥可以用于食品，“鸡骨泥这类肉糜类产品含有蛋白质、脂肪、矿物质（尤其是钙和磷）”。说得就差鼓励大家都去买点骨泥补补了。
淀粉肠的报道以及随之而来的汹涌舆情确实有不全面（指报道）与过激（指舆情）。例如报道没有明确哪些淀粉肠厂家在用骨泥，给人的印象这似乎是行业普遍现象，这本应有更详尽的证据。至于说骨泥人不能吃，也没有给出相关法规或科学上的依据。这种缺陷报道引发的舆情，自然也变得情绪多于理性。
但宣称骨泥用于食品没问题，还说里面有蛋白质、矿物质，也极为片面。用鸡骨泥做淀粉肠有诸多应该质疑的地方，怎能如此洗地？
其一，报道中提到的骨泥到底是什么，是否属于能用于食品的类型，还真不好说。说骨泥可以用于食用，是基于
机械分离肉，mechanically seperated meat（MSM，也有不同缩写MRM和MDM）。像网上大V说骨泥可食用，参考的也是机械分离肉相关资料。
机械分离肉是指通过高压等技术手段，将家畜家禽等屠宰后剩下的骨架上残余的肉类分离出来，形成的糜状肉类产品。可机械分离肉有明确的规定，例如在美国FDA的标准里，机械分离肉必须是骨固体含量低于1%。报道中的骨泥，出自一位淀粉肠生成厂家工作人员的透露。
这位工作人员说的骨泥可未必是食品加工里符合标准的机械分离肉！
机械分离肉是从骨头上搞出肉来，和骨泥一词很贴合。但作为一种肉类产品，机械分离肉只有符合特定标准才能这么称呼。报道里的骨泥可能和机械分离肉外观类似，不一定就是后者，完全有可能是不符合机械分离肉标准的骨头泥。因此，不能将淀粉肠里用到的骨泥，默认为只是用了机械分离肉而已。
其二，
机械分离肉的钙不是营养物质。网上有专家用这样一张表格描述鸡骨泥营养成分：
老百姓一看，骨泥不仅比猪肉低脂低糖，还比牛奶高蛋白高钙，简直是大补啊。
可机械分离肉里的钙不是营养物质！说骨泥有包括钙、磷在内的矿物质貌似准确，实则误导。
机械分离肉里多出来的钙来源只有一个：骨头。钙含量高说明在把肉从骨头上“剥离”出来时，带入了大量骨头。动物骨头里的钙是溶解度很低的无机盐沉淀，人体根本吸收不了。实际上，机械分离肉的标准是骨含量必须低于一定的值，一个检测方法就是
钙含量要低。
前述提到的FDA标准，成熟家鸡来源的机械分离肉，钙含量不能高于0.235%。而上表里的鸡骨泥，钙含量每千克6.6克，是0.66%，都超标了，倒还真是
骨头泥。
机械分离肉是要将肉取出来，不能把带上骨头说是多了矿物质。这也是为什么贸然将骨泥等同于机械分离肉有问题，因为咱根本不知道厂商用的是否是机械分离肉。
其三，机械分离肉使用有诸多规定，不能因为有用于食品行业就扩展为使用没问题。像前面提到的，机械分离肉本身就有生产标准，必须得是肉，不能真成骨头泥。除此之外，正经机械分离肉也有使用规定，例如按照欧美都规定
机械分离肉必须注明，不能简单说是鸡肉、猪肉等名字。
而为骨泥正名的一些文章描述骨泥时都提到肉糜，老百姓看了还以为因为外观类似，骨泥也能叫肉糜。如果参考欧美的法规，肉糜对应的应该是ground meat，机械分离肉恰恰绝对不被允许叫做ground meat。
国内的机械分离肉标准里出现了肉糜字样：
但同一个文件里也明确说了在食品包装时
必须注明机械分离和畜禽种类，如机械分离鸡肉，机械分离猪肉。可见称肉糜有误导嫌疑。毕竟中国老百姓说到肉糜，想到的大概率会是晋惠帝的何不食肉糜。将机械分离肉或是都不知道是啥标准做出来的骨泥，和肉糜等同，老百姓搞不好还以为这是皇帝吃的高档货了。
顺便说一下，2022年开始执行的《机械分离肉标准》GB/T 40463-2021，起草单位第一位是双汇，动物疫病预防控制中心是排在第二位，11个起草单位里6个是食品行业公司。不禁让人想到那句名言：一流企业做标准；二流企业做品牌；三流企业做产品；四流企业打价格。中国食品行业一流企业看来真不少。
我不太清楚国内所谓淀粉肠如何标注成分，可是成分表里写鸡骨泥已经超出我想象，写机械分离鸡肉、机械分离猪肉等的可能性更是微乎其微。除非央广网的记者或那位透露信息的工作人员都是胡说八道，淀粉肠相关新闻至少透露出一个信息：
有一些淀粉肠的原料标注有问题，不实。
当然，这可能只是极少数淀粉肠厂家，但这仍是值得相关部门注意，公众也有权知晓。连是否是合格的机械分离肉都难以确定的情况下，说什么无毒无害，有蛋白质、钙、磷，这不是瞎扯蛋吗？
实际上机械分离肉用于食用在生产过程中有严格的卫生要求，有些肉还不能用于食用的机械分离肉，比如由于疯牛病的威胁，美国
禁止机械分离牛肉进入食用。鸡和猪也不是每个部位都被允许制作机械分离肉，像鸡头、鸡脖等都不能用。
在用途上，机械分离肉可以用于热狗、肉丸子等，但美国这里牛肉汉堡不允许用机械分离肉。至于有些专家说的用机械分离肉增加风味，用于营养添加，我只能说，我不是专家，只是，无论啥用途，切割肉类做肉糜都没有理由劣于机械分离肉，用后者的唯一原因就是两个字：
便宜。
确实如一些专家说的，机械分离肉可以食用。但消费者绝对有权知道自己买的淀粉肠里到底有没有肉，以及用了什么肉。
例如我最近买的牛肉肠，成分表里清楚写着牛肉：
包装上也明确声明不用边角料（by-product）：
试想，如果我们对骨泥制作淀粉肠的态度是其实也可以吃的纵容，
不细究用的骨泥是否真属于机械分离肉，以及食品标注是否合规，那么万一还是有用料老实的食品企业，它们怎么过日子？长期以往，搞不好我们就真要吃骨头泥做的淀粉肠了。
也正因此，淀粉肠最初的报道虽有瑕疵，但也不该如此为淀粉肠洗地。
