in this study, quality of white button mushrooms (agaricus bisporus) treated by water and citric acid was evaluated during storage at 2 temperatures (room temperature and 4°c). the effect of modified atmosphere packaging (map, by 4±1% co2, 6±1% o2 and the remaining n2) with or without water absorbent (silicagel) was also evaluated. samples were assessed for their organoleptic properties (textur...

There is a demand to utilize modified atmosphere packaging (MAP) for prolonging shelf life of fresh date fruits (Barhi cultivar at Khalal stage of maturity). Barhi fruits are good source of fiber, carbohydrates, minerals and vitamins and have a sweet taste and popular in marketing. Respiration of the produce with proper gas exchange through the packaging films can create a modified atmosphere i...

The sensory, microbiological and physicochemical attributes of fresh meat stored at 5 and 15 degrees C were affected by the combined effect of volatile compounds of oregano essential oil and modified atmosphere packaging conditions (40% CO2/30% N2/30% O2, 100% CO2, 80% CO2/20% air, vacuum pack and air). It was found that the extension of shelf life of meat samples depended on the packaging cond...

Different modified atmosphere conditions with various CO2 concentrations on microbial load (psychrophile, mesophile aerobic and anaerobic bacteria) and physico-chemical properties of barramundi (Lates  calcarifer Bloch) fillets stored at 8°C were compared to determine the best packaging conditions. The gas conditions evaluated were 100% CO2 (M1), 75% CO2/25% N2 (M2), 50% CO2/50% N2 (M3), 25% CO...

Our objective was to assess the effects of lactate enhancement in combination with different packaging systems (vacuum; high-oxygen, 80% O2 + 20% CO2; or 0.4% CO, 30% CO2 + 69.4% N2) on beef Longissimus lumborum and Psoas major steak redness. Subprimals (n = 16) were divided in half and randomly assigned to 1 of 4 injection treatments (non-injected control, water-injected control, 1.25% lactate...

Respiration rate and gas exchange through the package material are the processes involved in creating a modified atmosphere inside a package that will extend shelf life of fresh fruits and vegetables. Thus, modelling respiration rate of the selected produce is crucial to the design of a successful modified atmosphere packaging (MAP) system. In this paper, general aspects of the respiration proc...

In modified atmosphere packaging (MAP) of horticultural produce, prediction of the evolution of gaseous O2 and CO2 concentrations inside packages is important to evaluate package performance and to reduce number of experimental trials needed to select packaging conditions. Mathematical modelling constitutes a useful tool in MAP design. A mathematical model for predicting oxygen (O2), carbon dio...
