Quality Properties

Blackberry fruits are fresh products with wide market possibilities but of very limited shelf life (3–6 days). To develop preservation alternatives, the effect and interaction of a modified atmosphere packaging and an edible coating based on guar gum were determined on the shelf life and quality properties of blackberry cv. Castilla stored at 5 ℃. Three types of packaging were evaluated: (1) perforated polyethylene terephthalate clamshells, (2) sealed polyethylene terephthalate clamshells, and (3) sealed polyethylene terephthalate clamshells with a polylactic acid film on top. In turn, two types of coating were evaluated: coatings of guar gum solutions at (1) 0.3% and (2) 0.4% in water. During storage, an index of deterioration and different quality properties were evaluated. In the polyethylene terephthalate packages with polylactic acid, an equilibrium modified atmosphere packaging was formed. Weight loss was much lower for the sealed polyethylene terephthalate and polyethylene terephthalate + polylactic acid (<2%) compared to fruits in perforated clamshells, with no significant differences between these two types of packaging. It was possible to observe the treatment with an edible coating of 0.3% gum guar and perforated clamshells (guar gum 0.3/N) presented the lowest deterioration rate and preserve the fruit longer time (13 days) although with a high weight loss (23.23%) while the treatment with polyethylene terephthalate and polylactic acid film + edible coating of gum guar (guar gum 03/polylactic acid) kept the samples during 12 days with a lower weight loss (1.75%). This latter combination of equilibrium modified atmosphere packaging with a biodegradable film and the guar gum edible coating can be an interesting treatment from a commercial point of view.

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.

Noni fruit (Morinda citrifolia L.) is a herbal remedy known for its therapeutic and nutritional value. However, it is perishable and subject to rapid postharvest deterioration that shortens its shelf life during storage. Therefore, this study investigated whether hot water dipping (HWD; 60°C, 1 min) and Modified Atmosphere Packaging (MAP; carbon dioxide and nitrogen) could prolong noni's shelf life. The noni physicochemical properties such as colour, firmness, weight loss, total soluble solids, titratable acidity and scopoletin content were monitored during six days of storage at room temperature. During storage, the noni skin colour changed from greenish-yellow to translucent yellow, but HWD storage was stopped on day 2 due to black spots' formation. The reduction of weight loss was significantly lowest in both MAP treatments (1.39–1.74%). Among these, N2-based had a significantly higher scopoletin content (27.12 mg/g) and firmness (0.8 N) compared to CO2-based, suggesting that it was the most effective postharvest treatment to efficiently prolong the shelf life and retained the quality and stability of noni during storage.

The present study studied the effect of chitosan coating with antibrowning agents, including naphthylacetate and cinnamon oil, and modified atmosphere packaging (MAP) on browning of sweet persimmons stored at - 0.3 ~ 0 °C for 3 months. The browning on the surface of sweet persimmons was effectively inhibited by chitosan - based coating and MAP treatment. After 3 months’ storage, samples coated + MAP exerted the lowest browning index(BI), polyphenol oxidase (PPO) activity and malondialdehyde (MDA) content, which indicated that the coated + MAP treatment could offer an excellent inhibitory effect on the browning. Both edible coating and MAP treatment cause changes in respiration rate of sweet persimmons. This research could be valuable for the development of application to edible coating and MAP for improving the shelf - life properties of sweet persimmons.

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 influence of modified atmosphere packaging (MAP) on quality attributes and shelf life performance of ‘Friar’ plums (Prunus salicina) was studied. Plums were stored at 0 °C and 85% relative humidity for a 60-day period in five different box liners (LifeSpan L316, FF-602, FF-504, 2.0% vented area perforated, and Hefty liner) and untreated (control). Flesh firmness, soluble solids concentration, titratable acidity, and pH were unaffected by the box liners. Fruit skin color changes were repressed on plums packed in box liners that modified gas levels and weight loss was reduced by the use of any of the box liners. Plums packed without box liners (bulk-packed) had ≈6% weight loss. High carbon dioxide (CO2) and low oxygen (O2) levels were measured in boxes with MAP box liners (LifeSpan L316, FF-602, and FF-504). Percentage of healthy fruit was unaffected by any of the treatments during the ripening period (shelf life) after 45 days of cold storage. However, after 60 days of cold storage, fruit from the MAP box liners with higher CO2 and lower O2 levels had a higher incidence of chilling injury (CI) symptoms, evident as flesh translucency, gel breakdown, and “off flavor” than fruit from the other treatments. Overall, results indicate that the use of MAP box liners is recommended to improve market life of ‘Friar’ plums up to 45 days cold storage. However, the use of box liners without gas control capability may lead to CI symptoms in fruit cold-stored for longer periods.

Seafood Products

Seafood products are highly perishable, owing to their high water activity, close to neutral pH, and high content of unsaturated lipids and non-protein nitrogenous compounds. Thus, such products require immediate processing and/or packaging to retain their safety and quality. At the same time, consumers prefer fresh, minimally processed seafood products that maintain their initial quality properties. The present article aims to review the literature over the past decade on: (i) innovative, individual packaging technologies applied to extend the shelf life of fish and fishery products, (ii) the most common combinations of the above technologies applied as multiple hurdles to maximize the shelf life of seafood products, and (iii) the respective food packaging legislation. Packaging technologies covered include: Modified atmosphere packaging; vacuum packaging; vacuum skin packaging; active food packaging, including oxygen scavengers; carbon dioxide emitters; moisture regulators; antioxidant and antimicrobial packaging; intelligent packaging, including freshness indicators; time–temperature indicators and leakage indicators; retort pouch processing and edible films; coatings/biodegradable packaging, used individually or in combination for maximum preservation potential.
