With the improvement of the global economic level, the demand for meat in various countries also increases. At the same time, the demand for meat packaging machines has also increased. Many people want to know about the methods of meat packaging. In this article, we will introduce this point in detail for you.
收缩包装方法
收缩包装方法是先将肉类包装好，然后使用肉类包装机抽出内部空气，再进行封口。然后将包装浸入热水或热气通道中。其目的是利用热能收缩，紧密包裹产品，使薄膜紧贴。最后对袋子进行真空处理。这是一种高效的肉类包装方法。
收缩包装可以采用袋子、袋子、托盘等形式。这些肉类包装袋的优点是产品外观光滑，肉质明显。而且在运输过程中不易破损。这种包装方法最早用于火鸡包装。由于效果良好，逐渐扩展到各种家禽、培根和香肠的包装。近年来，已扩展到鲜肉包装。
包装材料
其包装衬里最好为交联、双向定向的低密度聚乙烯，减少包装、储存和运输过程中的材料破损概率。此方法比改良大气包装和真空包装更简单、成本更低。
改良大气包装方法
Modified atmosphere packaging is a packaging method that completely extracts the air through vacuum operation. And then injects carbon dioxide, oxygen, nitrogen, and other gases into the bag to prevent the reproduction of microorganisms. If you want to pack pork, then you can use carbon dioxide and oxygen. And the oxygen infusion is 80%. This kind of gas packaging can keep the fresh meat in good condition within 7 days at 0~4℃. After 12 days, sensory determinations of activin, volatile base nitrogen, and pH in the packaging were all very low.
这种包装不需要冷冻，只需采取一定的冷却措施。在充气时加入二氧化碳和氧气。如果只使用二氧化碳，12天后，尽管新鲜度未下降，但颜色会变差。这是由于缺氧所致。为了在袋内保持肉的活力颜色，应添加一些氧气。要实现这种包装效果，需要用于肉类的改良大气包装机。
真空包装方法
真空包装方法是将肉装入真空塑料袋中进行包装。我们可以使用肉类真空包装机来实现。由于肉本身的生理功能，氧气会被迅速消耗，同时产生二氧化碳。通过这种方式，可以抑制细菌生长，延长肉的保鲜期，能在1°C下储存至少2个月。
At Taizy Machinery, we have many models of this type of vacuum packing machine for meat. This meat packaging equipment is very attractive to meat sellers and supermarket operators. Because it not only simplifies the process of the slaughterhouse but also greatly reduces the storage space compared with refrigerated white strips. It has the flexibility of turnover in purchasing and selling and can prolong the storage period of meat. This is the main methods of meat packaging.
