The Increase in Periods of Storage of Semiproducts of Animal Origin by the Action of Low-Temperature Plasma

Abstract

Food can be the cause of food poisoning of the human body. In this regard, it is necessary to pay special attention to its quality. The process of storage of animal origin food may cause changes, affecting the safety of its preservation. To maintain safety storage of food products a variety of techniques is used in the food industry and public catering: low or medium temperature, vacuuming, and preservative processing . However, these methods of influence on food products do not always provide full preservation of quality and microbiological characteristics. Objective: to investigate the effects of low-temperature argon plasma, generated by low-current high-voltage discharges under atmospheric pressure, on the duration of storage of small-piece semproducts of animal origin on the example of river and sea fish and beef. The work was carried out in the laboratories of the Buryat Scientific Center and the East- Siberian State University of Technology and Management. Traditional research methods were used to determine the total microbial number (TMN). Natural small-piece semiproducts from meat and fish were processed by low-temperature argon plasma and underwent a subsequent storage in a cooled state. In 3, 5 and 7 days TMN indicators were determined, which showed a slow growth of microorganisms in the studied objects in comparison with the reference sample during the whole period. And only in 7 days there was an excess of the permissible value of the TMN. The authors believe that the possibility of preliminary processing of semiproducts from fish and meat by low-temperature argon plasma in order to increase the storage time without changing the natural nutritional properties is promising.
