Is the cost of modified atmosphere lock fresh packaging high

Whether it is fresh food or cooked food, as long as it is exposed to air and left at room temperature for a period of time, it will spoil. Some are moldy and clumped, while others are rotten

Stinky, some decay and become sour, some become sour and sour. In order to ensure that consumers can eat healthy and safe food, the current preservation method is generally vacuum packaging

During the vacuum packaging process, food additives need to be added to achieve good preservation results. Vacuum packaging can also damage food fiber cells, affecting the taste,

In order to improve the quality of freshness preservation, a new packaging method called modified atmosphere packaging has been launched on the market.

The principle of a modified atmosphere packaging machine is to use a mixture of fresh-keeping gases (oxygen, nitrogen, and carbon dioxide mixed according to the characteristics of the food) to preserve the packaging box or packaging

The air inside the bag is replaced to change the external environment of the food inside the tray, thereby inhibiting the growth and reproduction of bacteria (microorganisms) and extending the shelf life of the food

Or shelf life. The composition and proportion of preservation gases vary for different foods. The specific modified atmosphere packaging process is as follows

Pre cooling: Generally, a professional vacuum pre cooler is used to quickly cool high-temperature food to below 10 degrees Celsius. Small scale production can use pre cold storage or low temperature

Alternative implementation of air conditioning and other methods. Reducing the time for bacterial growth, ensuring that the bacterial colonies do not exceed the standard before packaging, and that food does not spoil, are the basic prerequisites for modified atmosphere packaging.

Sales environment: Temperature is one of the most important factors affecting bacterial growth. Modified atmosphere packaged fresh meat must be delivered under cold chain conditions of 0~4oC

Anaerobic bacteria can still reproduce in modified atmosphere packaging under normal temperature conditions.

Packaging materials: Packaging materials not only affect aesthetics, but poor packaging materials can also affect gas permeability, thereby affecting the product's shelf life. They have anti fog properties

Effective cling film is the preferred choice for modified atmosphere packaging of cooked food products.

These three aspects basically determine the cost of modified atmosphere lock fresh packaging, while pre cooling and sales environment are one-time investments, and the cost is determined by the size of the scale, which can be low

Up to a few thousand yuan, it can also be as high as hundreds of thousands. The cost of packaging materials is a reflection of the sales cost of each box, and it is also a cost that businesses care about. Packaging materials are divided into boxes,

Sealing film and gas, taking cooked food as an example:

1. The size of the box is similar to that of Zhouhei duck, and the market price is between 0.35 yuan and 0.45 yuan.

2. The approximate price of sealing film varies from 30 yuan/kg to 55 yuan/kg depending on the material, and the cost of sealing a single box ranges from 0.1 yuan to 0.2 yuan.

3. Gas is relatively the cheapest cost, with a market price of around 80 yuan for a bottle of nitrogen and around 120 yuan for carbon dioxide. A bottle of nitrogen can fill 1000 boxes,

One bottle of carbon dioxide can fill 2500 boxes

According to rough calculations, the packaging cost price of a finished product is about 0.65 yuan, but the overall selling price of modified atmosphere packaging products is relative to the price of vacuum packaging and bulk packaging

The cost of modified atmosphere packaging may be even lower for production enterprises compared to vacuum packaging, as it is slightly higher.
