Modified atmosphere packaging, Transpiration, Weight loss, Apple Abstract. In the article the modified atmosphere packaging (MAP) of post-harvest apples are developed and evaluated. Firstly, the comparison package box with MAP and without package is developed and applied to make comparison experiments of post-harvest apples during storage of 30 days, 60 days and 90 days. Secondly, the influence of MAP on the transpiration of post-harvest apples is evaluated by comparison experimental studies, the respiration model and the change of water loss for post-harvest apples is analyzed. These results show that, within the initial storage of 20 days the change of water loss of apples with MAP or without package is approximate and almost linear. After 20 days of storage duration, the two cases of water loss have obvious difference, the water loss by transpiration for apples without package still shows linearity and maintain constant transpiration rate, yet the transpiration rate of apples with MAP would gradually decrease. In addition the transpiration of post-harvest apples with MAP can be effectively retarded at high relative humidity, and the post-harvest may maintain better quality and 90 days shelf life at storage condition of constant temperature 5°C and relative humidity 60%.

AbstractFresh-cut lettuce is a very well-known salad for today's routines because it obliges minimal preparation to minimize the loss of health beneficial vitamins, minerals, antioxidants and other phytochemicals. It is a prodigious challenge to serve its consumers fresh. Quality of freshly processed lettuce under high CO2 modified atmosphere packaging (MAP) has been investigated as a realistic alternative technique for its preservation. Storage under high CO2 atmospheric treatments exhibited a significant impact in microbial development, electrolyte leakage, volatile metabolites and sensory quality of fresh-cut iceberg lettuce. This storage condition (MAP 1: 5 kPa O2 and 20 kPa CO2 balanced by N2 at 7 °C for 6 days) inhibited the growth of mesophilic bacteria and yeasts; delayed the enzymatic browning (cut-edges and intact surface) of fresh-cut iceberg lettuce and overall visual quality was also in acceptance limit. The development of off-odors was perceived in high CO2 MAP as a consequence of volatiles (ethanol and acetaldehyde) accumulation which was persisted at an inexcusable level during 6 days of storage periods.

The study of the effect of the modified atmosphere packaging on quality of the bread was done after replacing wheat flour with amaranth flour in replacement of wheat flour for 0, 5, 10 and 15% by weight. The bread was stored for one, three and seven days in the ATM, 100% N2 and 30% CO2. The study proved the 30% CO2 modified atmosphere to be the optimal storage condition. It allowed to preserve volume, water content and contributed at least to increase in hardness of bread, which with the addition of amaranth flour decreased. The colour of bread during storage was characterised by the increase in L* parameter and decrease in a* and b*. For the decreased storage time, the effect was opposite. The replacement by 5% of amaranth flour increased the polyphenol content and did not affect bread quality.

Custard Apple

Custard apple, a tropical fruit, is underutilized because of its poor storability. Researchers have worked on various aspects for improving the storage life of fruits; still its storage life is limited to few days. So to counteract this, an experiment was conducted to study the effect of modified atmosphere packaging using three different kinds of films along with low temperature storage at 8, 12 and 15 °C and observations were recorded at weekly interval. The study indicated an increasing trend in the respiration rate and ethylene production rate as well, and the rate increased with increase in storage temperature and duration. The physiological loss in weight in packed fruits showed a drastic reduction. Titratable acidity increased as storage duration while ascorbic acid shown exact reverse trend. There was significant increase in reducing sugar and total sugar as duration increased but rate was low in 8° C fruits.

Storage Characteristics

In 1987, 1988, and 1989, the behavior of four different table grape varieties including Alden, Concord, Himrod, and Vanessa were studied during storage at 0°C.The first objective of our study was to determine the behavior of table grapes in modified atmosphere packages in terms of general acceptance. After three years of experimenting with these three films we were able to obtain a modified atmosphere of about 3% O2 and 10-15% CO2 at 0°C using a 3 mil thickness LDPE.Our second objective was to use moisture absorbents as a means of reducing the relative humidity inside the void volume of a package by the inclusion of different desiccants in the package to establish a desirable relative humidity.Examining different storage characteristics, our data showed that `Himrod', `Vanessa', and `Concord' grape clusters stored in the presence of KNO3 and KCl had better quality compared to grape clusters stored in the presence of other sorption compounds or controls with no sorbants.

Postharvest Life

The commercial use of modified atmosphere packaging (MAP) technology provides a means to slow the processes of ripening and senescence during storage, transport, and marketing of many fresh fruit and vegetables. The benefits of MAP and controlled atmosphere (CA) technologies for extending postharvest life of many fruit and vegetables have been recognized for many years. Although both technologies have been and continue to be extensively researched, more examples of the impacts of CA on produce quality are available in the literature and many of these reports were used in development of this review. Storage using MAP, similar to the use of CA storage, impacts most aspects of produce quality although the extent to which each quality attribute responds to CA or modified atmosphere (MA) conditions varies among commodities. Impacts of MAP and CA on flavor and aroma are dependent on the composition of the storage atmosphere, avoidance of anaerobic conditions, storage duration, and the use of fresh-cut technologies before storage.

After being caught and filleted, fresh rice field eel fillets were impregnate with chitosan coating solutions, and then stored in modified atmosphere package (MAP) (60%CO2 + 40%N2) at 2 °C for up to 25 days to determine the chemical, biochemical and physical changes. Fillets were left untreated (CN), or were treated with chitosan coating (CC), or combined chitosan coating with MAP (CCM). Total plate count (TPC), trimethylamine (TMA-N), total volatile bases (TVB-N), pH, colour, water loss, colour changes and hardness were monitored periodically. The results indicated that coating and MAP treatments retard the decay of fish compared to untreated samples. CCM more efficiently inhibited the growth of TPC (2-2.6 Log reductions during Astorage) than did CN and CC. CCM treatments predominantly reduced chemical spoilage, reflected in TVB-N, pH, and TMA-N, retarded water loss and maintained colour and hardness.

The effects of vacuum (VP) and 100% N2 modified atmosphere packaging (MAP) on the qualityand shelf-life of sliced pangasius catfish (Pangasianodon hypophthalmus) during refrigerated storage (4°C)were investigated up to 12 days. The values of pH, total volatile base nitrogen (TVB-N) and thiobarbituricacid reactive substance (TBARS) of sliced fish samples during storage under VP and MAP packaging werewithin the limit acceptable for chilled fish. Total viable count (TVC) of pangasius fish, on the other hand,gradually increased from the initial value of 4.32±0.04 to 8.30±0.13 log CFU/g on day 9 for non-sealedpack (control) and 7.64±0.12 and 8.34±0.07 log CFU/g for VP and MAP on day 12. There were nosignificant (p<0.05) differences in TVC values among the three packaging conditions during the storageperiod except on day 9 where significantly (p<0.05) lower TVC values were observed in the VP samplecompared to that of other samples. Based on the bacterial counts of 7 log CFU/g, which is considered as theupper acceptable limit for fresh and frozen fish, the shelf-life was determined as the excess of 6 days forcontrol pack and MAP samples, and excess of 9 days for VP sample. Therefore, VP is a good option toincrease the shelf-life of wet fish, which can be adopted by the superstores to display their products withextended shelf-life.
