Currently, several prestigious government university centers under the support of West Asia Steel are using the machines of this company for free in their laboratory environment and are engaged in research. Our goal is to obtain valuable information from the mentioned tests and provide this information for free to manufacturers.

In the research conducted in 2018 by the professors of Bu-Ali Sina University in Hamedan- IRAN on the subject of “estimating the effect of chitosan solution, packaging with nano method and modified atmosphere method on the physical, chemical and mechanical characteristics of button mushroom during its storage” with the semi-automatic device of West Asia Steel Company was used. It brought important achievements in the field of precision implementation of the modified atmosphere method using our devices.

In this research, mushrooms that were impregnated with chitosan solution and mushrooms that were not impregnated were tested in three types of normal packaging, packaging using nano films and packaging with nano films along with the modified atmosphere method. Packages were prepared with certain percentages of gases and nano films (a capsule containing oxygen and carbon dioxide was prepared). The packages were packed in dimensions of 7*15*20 cm using a semi-automatic seal vacuum machine. Oxygen and carbon dioxide were measured every two days for ten days by a gas measuring device.

The use of nano film (due to less access to oxygen and carbon dioxide) along with the modified atmosphere method had a positive effect on the control of the mushroom respiration rate and the physical, chemical and mechanical characteristics of this product and increased the shelf life of the mushroom and preserved its characteristics.

Due to the fact that this research has been published in prestigious journals and has an ISI rating, extreme care must be taken in the conditions of the test and the materials used, and the use of high-quality and high-precision devices should be observed in this research according to the results obtained. It is possible to understand the accuracy of our machines in the implementation of the MAP method.
