APPLICATIONS OF DYNAMIC MODIFIED ATMOSPHERE PACKAGING SYSTEMS FOR FRESH RED MEATS: REVIEW³

Abstract

Shelf‐life and quality of fresh red meat can be extended by using modified atmosphere packaging (MAP) coupled with refrigerated storage. MAP with elevated levels of carbon dioxide and reduced levels of oxygen inhibits the growth of various aerobic spoilage bacteria and prolongs color stability of fresh red meat. However, in‐package headspace conditions are dynamic because of permeability of packaging films, microbial growth, pigment oxidation, gas absorption and mobilization in meat, and lipid oxidation. To further extend the shelf‐life and quality of meat, dynamic MAP systems are required to respond to the changes in packaged meat. This review focuses on the changing conditions within the microenvironment of packaged meat. The growth of microorganisms, meat pigment oxidation, and carbon dioxide absorption in MAP fresh red meats are considered. Examples of various dynamic MAP systems currently in use are given, along with the specific requirements of each system regarding meat fabrication, packaging, distribution, and display. Mathematical models, as a tool to understand in‐package micro‐environment modifications over time and how these changes influence meat quality and shelf‐life, are also discussed.

Czynniki kształtujące jakość mięsa drobiu grzebiącego. Praca przeglądowa

“…Podstawowym barwnikiem świeżego mięsa, decydującym o jego charakterystycznej barwie, jest mioglobina, która może występować w trzech formach: jaskrawoczerwonej oksymioglobiny (MbFe(II)O 2 ), ciemnoczerwonej mioglobiny (MbFe(II)) i brunatnej metmioglobiny (MbFe(III)), w zależności od ciśnienia cząstkowego tlenu w atmosferze [Pikul i in. 1988;Zhao, Wells, McMillin 1994;Krala 2001;Faustman 2001]. Mioglobina przy swobodnym dostępie powietrza łatwo łączy się z tlenem cząsteczkowym, przechodząc w utlenowaną oksymioglobinę.…”

A Review on Some Organic Acids Additives as Shelf Life Extenders of Fresh Beef Cuts

“…It undergoes deterioration progressively from slaughter until consumption. The shortened shelf-life is due to microbial growth and/or rancidity development which is strongly influenced by initial beef quality, package parameters and storage conditions [7] . Microbial growth is the most important factor in spoilage of fresh beef and this is followed by colour deterioration.…”

Predictive model for the growth of Yersinia enterocolitica under modified atmospheres

“…Several authors have mentioned that low temperatures have a synergistic effect on CO 2 because of the inverse relationship between CO 2 solubility and temperature (Wolfe 1980;Zhao et al 1994). However, Devlieghere et al (1998) demonstrated that modifications in the temperature range from 4 to 12°C have a minor effect on the solubility of CO 2 .…”
