The Ascendant Packaging

Modified atmosphere packaging, namely gas replacement packaging, also known as MAP packaging (ie Modified atmosphere packing), its preservation gas is generally composed of carbon dioxide, nitrogen, oxygen and a small amount of special gas, because it can effectively extend the product shelf life, to ensure product Freshness, and thus has entered the European and American food market since the 1980s, the development trend has been very good, the annual growth rate of 25%.

Since the technology was used by Chinese food companies in the early 90s of last century, it has now received widespread attention from companies in the industry. The reporter interviewed a number of those who are using or planning to use this technology for the advantages of this technology and its development in the country. Business.

This article thanked the managers of Beijing Yishidaxin Food Co., Ltd., Beijing Quanjude Company, Shandong Dezhou Shengji Group Co., Ltd., and the relevant person in charge of Shuanghui Group for their strong support.

What are the advantages of modified atmosphere packaging?

According to the related personnel of Beijing Quanjude Company, compared with ordinary vacuum packaging, modified atmosphere packaging can really play a role in keeping freshness. The person in charge said that for fresh meat, ordinary vacuum packaging causes lavender meat because of the lack of oxygen in the package, and it is often mistaken for consumers to believe that it is not fresh and affects sales. The modified oxygen environment can effectively maintain the red oxygenated myoglobin in fresh meat, making the product more fresh, avoiding changes in the color of raw meat caused by lack of oxygen in vacuum packaging, product extrusion and shrinkage of packaging appearance. problem.

Mr. Yu of Beijing Yishidaxin Food Co., Ltd., which has been using modified atmosphere packaging for all products for a long shelf life, said that modified atmosphere packaging can extend the shelf life of products. The use of modified atmosphere packaging products can be kept at room temperature (20-25 °C) for 18 days, in the case of 0--5 °C can be up to 60 to 90 days, while the ordinary vacuum packaging shelf life of only about 30 days (0 to 5°C).

It can guarantee the original flavor of the product compared to other forms of packaging, the advantage of modified atmosphere packaging is more obvious. The vacuum packaging generally undergoes a high-temperature sterilization process, which easily affects the taste of the product, and the modified atmosphere packaging does not need to go through the above-mentioned process, thereby effectively guaranteeing the authenticity of the food.

Beautiful appearance Shuanghui Group, Beijing Quanjude, Beijing Yishi Daxin relevant person in charge also said that the appearance of modified atmosphere packaging is very beautiful, not like the vacuum packaging as the product is extruded, and the appearance of shrinkage phenomenon.
Which companies are suitable for using modified atmosphere packaging

According to Mr. Yu of Beijing Yishi Daxin, due to the high cost of vacuum packaging equipment and fresh air, the following companies are more suitable to use this equipment:

1, the old company

For the time-honored and gold-labeled companies that pay attention to maintaining the traditional flavor, focusing on product quality and brand image, the modified packaging is undoubtedly the best choice.

2. Enterprises with certain economic strength will need stronger economic strength to support long-term production due to the increase in gas cost of modified atmosphere packaging. For enterprises focusing on product diversification and brand, the products with modified atmosphere packaging have high freshness preservation. , long shelf life, does not destroy the nutritional composition of products, natural, health and other characteristics, is undoubtedly the biggest selling point of high-end products. And as an emerging technology, modified atmosphere packaging can help companies improve their image.

Modified atmosphere packaging calls for appropriate testing equipment

Beijing Jingqi Shenfangyuan Technology Co., Ltd. has used modified atmosphere packaging technology in some products, but related personnel said that this technology development is not yet mature, especially domestic equipment. The company uses an ordinary imported equipment. After a certain period of time, air leakage has occurred. However, the corresponding domestic air-conditioning testing equipment technology is still immature, and it is impossible to pick up the air leakage packaging, thereby causing the product to deteriorate. In addition, the responsible person also said that the relatively high cost of fresh air required for modified atmosphere packaging is one of the factors that hinder the promotion of this product in China.
