Loquat fruits (Eriobotrya japonica Lindl cv. `Algerie') were stored in modified atmosphere packaging (MAP), using five types of microperforated polypropylene (PP) films during 2, 4, and 6 weeks at 2 °C and for a subsequent period of 4 days at 20 °C shelf life (SL) out of the bags. Loquat fruits stored without packaging and in normal air served as control. The atmosphere composition at the steady state depended on the film permeability, ranging from 1.2 to 8.5 kPa for CO2 and from 19.5 to 13 kPa for O2 as film permeability decreased. Weight loss was drastically reduced by MAP conditions. Softening, color evolution, and decreases in sugars and organic acids were delayed, these effects also being evident after the SL period. Scores for visual aspect and facility of peeling were also higher for loquat stored in MAP than for controls. Taking into account results form all quality parameters, the most suitable atmosphere for loquat storage was found to be around 2—4 and 16—18 kPa for CO2 and O2, respectively, reached in the PA-80 and PA-60 films. In addition, the storage period for optimum loquat quality maintenance was established as 2 weeks of cold storage plus SL for control fruits, while under MAP conditions, storage periods could be extended up to 6 weeks plus SL, especially using PA-80 and PA-60 films.

Cornelian cherries were stored in two types of polymeric films (low density polyethylene and polypropylene) and three gas combinations 5%O2 + 20%CO2 + 75%N2, 60%O2 + 20%CO2 + 20%N2 and Air) at 1 °C and 90-95% relative humidity for 35 days. Unpackaged cornelian cherries were used as a control. Samples were taken initially and at intervals of 7-days during storage, when quality parameters were measured. Results showed that modified atmosphere packaging (MAP) allowed the stored fruits to retain their weight and visual quality throughout the experiment, regardless of the gas combinations used, while by the end of the storage period the unpackaged fruit lost over 30% of their weight and consequently visual quality. Overall, packaging in 60%O2 + 20%CO2 polypropylene (PP) and air low density polyethylene (LDPE) could retard soluble solid contents, titratable acidity, ascorbic acid, anthocyanin index decrease and pH increase during the storage time. Additionally, such packaging could lead to better surface color preservation than that of fruits kept in open containers. Furthermore, packaging in air low density polyethylene and 60%O2 + 20%CO2 low density polyethylene could delay total phenolics accumulation and increase peroxidase activity to levels higher than those in the control. During the maintenance period, no symptoms of decay were observed.

The effects of combined aminoethoxyvinylglycine (AVG) and modified atmosphere packaging (MAP) treatments on quality attributes of ‘0900 Ziraat’ sweet cherry fruit during the cold storage and shelf life were investigated in this study. Significantly lower weight loss and decay ratios were observed in all treatments throughout the cold storage period as compared to the control. A similar case was also observed referring to the shelf life. MAP treatments were found to be more effective in retarding the weight loss and decay ratio. Higher hue angle values were measured from AVG-treated fruit at harvest. Similarly, hue angle of AVG and MAP-treated fruit were also higher than for the control in all periods of cold storage and on the 7th and 21st day of shelf life. AVG-treated fruit had higher firmness values than the control at harvest. However, higher firmness values were measured from MAP-treated fruit during the cold storage and shelf life. At the end of cold storage, lower SSC and higher titratable acidity values were observed in AVG and MAP-treated fruit than in the control. AVG + MAP treatments yielded significantly higher vitamin C, total phenolics and antioxidant activity values than the control. Contrarily, the control fruit had significantly higher total monomeric anthocyanin than the other treatments. Based on current findings, it was concluded that combined AVG + MAP treatments could be used as a beneficial tool to maintain the quality of sweet cherry fruit throughout the cold storage and shelf life.

The effects of passive- and active-modified atmosphere packaging (passive- and active-MAP) were investigated on the physio-chemical and quality attributes of fresh in-hull pistachios stored at 4 ± 1 °C and 90 ± 5% R.H. Fresh pistachios were packaged under each of the following gas combinations: active-MAP1 (AMA1) (5% O2 + 5% CO2), AMA2 (5% O2 + 25% CO2), AMA3 (5% O2 + 45% CO2), AMA4 (2.5% O2 + 5% CO2), AMA5 (2.5% O2 + 25% CO2), and AMA6 (2.5% O2 + 45% CO2), all balanced with N2, as well as passive-MAP (PMA) with ambient air (21% O2 + 0.03% CO2 + 78% N2). Changes in quality parameters were evaluated after 0, 15, 30 and 45 days of storage. Results demonstrated that AMA6 and PMA had significantly lower (7.96 Log CFU g−1) and higher (9.81 Log CFU g−1) aerobic mesophilic bacteria counts than the other treatments. However, the AMA6 treatment decreased, kernel chlorophyll and carotenoid content, hull antioxidant capacity, and anthocyanin content. The PMA treatment produced a significant weight loss, 0.18%, relative to the other treatments. The active-MAP treatments were more effective than the passive-MAP in decreasing weight loss, microbial counts, kernel total chlorophyll (Kernel TCL), and kernel carotenoid content (Kernel CAC). The postharvest quality of fresh in-hull pistachios was maintained best by the AMA3 (5% O2 + 45% CO2 + 50% N2) treatment.

The present article investigates the effect of sodium lactate on microbiological, physico-chemical and sensory characteristics of lightly salted Pacific herring ( Clupea pallasii ) and Baltic herring ( Clupea harengus membras ) during refrigerated storage 5 ± 0.3°C. There have been analyzed different processing methods of lightly salted samples of Pacific and Baltic herring: control (without sodium lactate), and experiment (3% sodium lactate), both in vacuum packaging and modified atmosphere packaging (MAP - 40% CO2/60% N2). For vacuum and MAP there were used bags with low oxygen permeability (3 cm3/m2/day). It was found that 3% sodium lactate keeps firmness of the texture of salted fish muscle and reduces the release of water into the package during storage. Adding 3% sodium lactate reduces the value of the water activity in lightly salted Pacific and Baltic herring by 0.01-0,012 units. The lowest pH (0.02 units) was registered in samples without sodium lactate packed in MAP. Organoleptic signs of spoilage in fish without sodium lactate appeared much earlier, and using 3% sodium lactate both in vacuum and in MAP helped protect and improve organoleptic characteristics of the product during storage. Total biological semination of experimental samples packed in MAP kept at the very low level during the whole storage period, i.e. combined effect of using 3% sodium lactate and MAP inhibited microbial growth. This combination allows to reduce twice the rate of accumulation nitrogen in terminal amino-groups and to increase 1.5-2 times storage life of lightly salted Pacific and Baltic herring, compared to their storage life in vacuum packaging without sodium lactate. The results obtained allow us to recommend using sodium lactate in production of lightly salted fish in oxygen-free packaging, especially in modified atmosphere packaging (40% CO2/60% N2).

Abstract Background Barberry has long been used as an herbal remedy since ancient times which is found throughout temperate and subtropical regions of the world. Given the short harvesting season and limited shelf life of the barberry, we evaluated the possibility of using modified atmosphere packaging and oxygen-scavenger sachets to increase its storage period. For this purpose, the physicochemical characterization (antioxidant activity, anthocyanin, phenolic compounds, and ascorbic acid content, acidity, firmness, color, and decay incident) of fresh barberry samples packaged within different atmospheres was investigated over 4 weeks of storage at 4 and 25 °C. The barberries were packaged with low-density polyethylene/polyester (LDPE/PET) films under natural atmosphere (C), N2 gas (N), vacuum (V), or in the presence of an oxygen scavenger (OS). Results The results revealed that with increased storage period, the O2 and CO2 levels inside the packages decreased and increased, respectively. The antioxidant activity and amounts of anthocyanin, phenolic compounds, and ascorbic acid all decreased with increasing storage period. Among the studied atmospheres, the OS and, subsequently, V packages were most capable of maintaining the quality of fresh barberries, with the decay incidence being approximately 30 times lower inside these packages relative to the control. Increasing the storage temperature accelerated the intensity of chemical changes and decay across all samples. Conclusion The barberries inside the OS packages stored at 4 °C (and even at 25 °C) still had good sensory properties in terms of chemical properties, texture, and color after 4 weeks. Fortunately, it seems that this packaging technology makes the exportation and delayed consumption of the fresh barberry possible by maintaining its quality.

The experiment was conducted to evaluate the effect of packaging materials on the quality and shelf life of green chili (Capsicum annuum) using passive modification of modified atmosphere packaging system. The modified atmosphere was created by making perforation in the polypropylene packets. Green chili pre-treated with chlorine water and then packaging in 0.3% perforated polypropylene packet resulted substantial reduction of weight loss and rotting/shriveling. These treatment combinations also considerably retained vitamin C, ß-carotene, moisture content, etc. Under this condition the retention of quality and shelf life of green chili could be extended up to 10 days at ambient condition as compared to non-treated and without packaging.

This study investigated the isolated effect of modified atmosphere packaging (MAP; 50% CO2 and 50% N2) and ultraviolet radiation (UV; 0.30 J/cm2) as well as their combined (MAP/UV) effect on reduction of Salmonella typhimurium and Escherichia coli O157:H7, biogenic amines (BA), and on shelf life of tilapia fillets stored at 4 ± 1 °C for 10 days. UV samples had the highest reduction of S. typhimurium (1.13 log colony forming units/g; CFU/g) and E. coli O157:H7 (0.70 log CFU/g). MAP and MAP/UV reduced the growth of S. typhimurium in 0.50 log CFU/g and did not affect the growth of E. coli O157:H7. UV, MAP, and MAP/UV increased lag phase and/or generation time of all evaluated bacterial groups, decreased pH values, ammonia formation, texture changes, and, in general, the BA formation throughout storage period, and, therefore, UV, MAP, and MAP/UV extended the shelf life for two, three, and at least five days, respectively. MAP/UV, MAP, and UV decreased redness, MAP/UV and MAP increased yellowness and lipid oxidation, while UV did not affect it. MAP/UV demonstrated promising results for shelf life extension; however, different gas ratios in combination with other ultraviolet radiation type C (UV-C) doses should be investigated to reach the highest microbiological safety and maintenance of the overall quality of tilapia fillets.

Abstract Objectives The study was conducted to prolong the shelf life of freshly harvested pomegranate fruits and to find out its physiochemical properties during storage. Materials and Methods Pomegranate fruits of variety ‘Bhagawa’ were stored in 200, 300 gauge high-density polyethylene (HDPE) package, and silicone membrane modified atmospheric storage system at ambient conditions and 10°C. Gas composition inside the package, texture, color, and overall quality parameters were evaluated at these two storage temperatures. The physico-chemical properties such as total soluble solids, titratable acidity, ascorbic acid content, total, reducing, and non-reducing sugars, and physiological loss in weight (PLW) were also determined. Results In ambient storage, the shelf life of pomegranate fruit was 10 days, whereas in modified atmosphere packaging (200 gauge HDPE, 300 gauge HDPE, and silicone membrane system), the shelf life of pomegranate fruits was extended up to 60, 60, 25 days at ambient and 96, 96, 65 days at 10°C temperature, respectively. Conclusions Among the 200, 300 gauge HDPE package, and silicone membrane system treatments T1, T5, and T8, respectively, were found better with respect to all the sensory and quality parameters studied.
