The commonly seen box style modified atmosphere packaging video uses modified atmosphere packaging technology. Modified Atmosphere Packaging is commonly referred to as Modified Atmosphere Packaging or Replacement Gas Packaging or Inflatable Packaging in China.
Also known as MAP or CAP abroad. The principle of modified atmosphere packaging is to use gas for preservation. The video screen undergoes a modified atmosphere packaging inspection before leaving the factory to ensure food safety.
Principles of Modified Atmosphere Packaging
The commonly used gases for modified atmosphere packaging include N2, O2, CO2, combined gas O2+N2 or CO2+N2+O2 (i.e. MAP). Modified atmosphere packaging technology can be widely used
Widely used for preserving various types of food, extending food shelf life, and enhancing food value.
The Birth of Modified Atmosphere Preservation Technology
Aaron Brody first developed Modified Atmosphere Packaging (MAP) technology when he worked at Whirlpool in 1950. He said:
Our original intention was to improve the quality of refrigeration equipment in the United States. Previously, we had never applied this technology to domestically produced refrigeration equipment,
But it applies technology to the production and distribution of fresh meat products
After Aaron Brody developed the relevant technology for fresh meat production, in the late 1960s, DickPerdue immediately developed it
Cryovac system for packaging fresh meat products.
The integration of these two innovative technologies has rapidly promoted the meat industry to achieve significant cost and waste reduction goals, enabling the meat industry to contribute to
The rapidly increasing global population effectively and affordably provides fresh and nutritious products.
Aaron Brody said, "When it comes to fresh meat, if we consider the starting point of the industry, we have actually taken into account the typical products of meat."
The shelf life has been extended by five to ten times. Taking meat filling products as an example, we have doubled their shelf life; And fully sliced beef products,
Its current shelf life has been extended by two to three times
The packaging industry has taken solid steps to change the distribution system of fresh red meat products. The first change in this distribution system is to transform livestock
Transfer to the enclosure in the city center and then package in a factory located in downtown Colorado, Iowa, USA, which is close to livestock
The livestock ranch is very close. I know many industry insiders think this approach is bad, but in reality, it is very effective, which makes me
We no longer need to transport the waste products after animal slaughter, which effectively improves our transportation efficiency Aaron Brody continued.
This innovative approach has completely revolutionized the entire meat industry, significantly reducing the amount of meat waste and reducing costs by millions of dollars,
The waste generated during the production process has also decreased by millions of pounds.
Principles of Modified Atmosphere Packaging
Temperature control
The issue we need to worry about is temperature. Without temperature control, everything will become empty talk. When packaging meat products and in the distribution process, we
Special attention needs to be paid to the temperature of the product. Similarly, in retail settings such as supermarkets, the temperature and control of meat products are also very important
The packaging of meat products is completed in a freezing environment of 1.7 ℃~3.3 ℃. The temperature in the logistics distribution environment is -0.5 ℃, while the temperature in the retail environment is easily out of control.
By using refrigeration equipment, enhancing the ability of modified atmosphere preservation inside the packaging, ensuring the correct microbial environment inside the packaging, and minimizing changes in growth rates, all of these measures require
We always ensure that the temperature control of the product is within our control range. An effective and intelligent packaging system requires this prerequisite in particular.
In intelligent packaging systems, environmental changes are prone to occur in the distribution process, which requires operators to pay appropriate attention to. Aaron Brody stated:
The intelligent packaging system can perceive changes in the external environment and make appropriate adjustments based on these changes. For example, when the temperature of the external environment in which the product is located
When it is too high, appropriate adjustments can be made inside the packaging to cool it down. If the oxygen content in the external environment is too high, adjustments will be made inside the packaging to reduce it independently
"Low oxygen content."
Positive and effective packaging can further enhance this function, allowing product packaging to respond quickly to changes in the external environment. Aaron Brody stated:
In smart and active packaging, packaging materials typically contain unique physical or chemical substances that can be captured and measured inside the product packaging
Changes in packaging materials, resulting in an increase or decrease in oxygen content within the packaging, creating a unique internal environment while maintaining a continuous process within the packaging
