ABSTRACT: Strawberry is one of the most popular fruits worldwide. Therefore, it is important to maintain its supply and freshness and potency guaranteed from the farms to the point of consumption. Strawberries spoil rapidly and the quality changes with storage delays. However, little is known about the effect of storage methods on the changes of its quality. In this study, two storage methods; Cold Storage (CS) and Modified Atmosphere Packaging (MAP) were investigated to see how it will maintain its quality. Results obtained showed that storage method has an effect on keeping its quality, and it proved that MAP is the acceptable storage method because it kept on strawberry quality, extended storage period, and decreased weight loss, in contrast, showed the highest fruit decay, in compare to the cold stored fruits. And that means; MAP can be useful supplements to provide optimum storage conditions (temperature and relative humidity) and maintain the quality of fresh strawberry fruits after harvest.

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 Individual

Okra possesses a short shelf-life which limits its marketability, thereby, the present study investigates the individual and combined effect of 1-methylcyclopropene (1-MCP) and modified atmosphere packaging (MAP) on the postharvest storage life of okra. The treated/ untreated okra samples were stored at ambient (i.e., 27 °C) and low (i.e., 7 °C) temperatures for eight and 20 days, respectively. Results revealed that the 1-MCP and/or MAP treatment successfully inhibited fruit softening, reduction in mucilage viscosity, and color degradation (hue angle, ∆E, and BI) in the product resulting in a longer period of shelf-life. However, MAP with or without 1-MCP was more effective to reduce weight loss in okra stored at both ambient and cold storage conditions. Additionally, ascorbic acid and total antioxidants were also retained in 1-MCP with MAP during cold storage. The 1-MCP in combination with MAP effectively suppressed respiration rate and ethylene production for four days and eight days at 27 °C and 7 °C temperature conditions, respectively. According to the results, relatively less chilling injury stress also resulted when 1-MCP combined with MAP. The combined treatment of okra pods with 1-MCP and MAP maintained the visual quality of the product in terms of overall acceptability for four days at 20 °C and 20 days at 7 °C.

Alternatives to sulfur dioxide to maintain quality of table grapes, including various combinations of rachis removal, chlorinated wash, hot water treatment, and modified atmosphere packaging, were explored in this study. Grapes were prepared by cutting off the rachis 1 to 2 mm from the fruit or by keeping the clusters intact. After initial preparation, short-stem and cluster grapes were subjected to chlorinated wash and/or hot water (45 °C, 8 min) treatment and packaged in plastic trays sealed with a gas-permeable film. The treated grapes as well as the commercially packed grapes (COM) in their original packages were stored at 5 °C for up to 4 weeks. Hot water treatment resulted in significantly (P < 0.05) higher oxygen retention and lower carbon dioxide accumulation in package headspaces, maintained a firmer texture, higher overall visual quality, lower decay rate, and lower microbial populations than other treatments or COM during the entire storage period. Grapes that were cut from the rachis and treated with hot water and chlorine maintained the highest quality for 4 weeks with the least decay among all treatments. A chlorine prewash treatment significantly (P < 0.05) reduced microbial populations on cluster grapes and maintained better overall quality. Conventional COM grapes developed dark decay and lost turgidity and were of unacceptable quality at 28 days of storage.

This research was carried out to extend the postharvest storage of japanese plum (Prunus salicina Lindl. cv. Tegan Blue), which has a short shelf life limiting its export potential. The effects of 1.0 μL·L−1 1-methylcyclopropene (1-MCP) and modified atmosphere packaging (MAP), alone or in combination, on quality of mature japanese plum fruit during storage (0 ± 1 °C and 90% ± 5% relative humidity) were investigated. The activities of enzymes of ethylene biosynthesis [1-aminocyclopropane-1-carboxylic acid synthase (ACS), 1-aminocyclopropane-1-carboxylic acid oxidase (ACO), and 1-aminocyclopropane-1-carboxylic acid (ACC) content] and those of cell wall-associated enzymes [exo-polygalacturonase (exo-PG), endo-polygalacturonase (endo-PG), pectin esterase (PE), and endo-1,4-β-D-glucanase (EGase)] were also measured. 1-MCP-treated fruit stored in normal atmosphere or in MAP had lower ACC content and inhibited ethylene production with reduced ACS and ACO activities compared with fruit stored in MAP and in normal atmosphere. Similarly, 1-MCP-treated fruit, stored either in normal atmosphere or in MAP, were firmer with reduced exo-PG, endo-PG, PE, and EGase activities compared with fruit stored in MAP and in normal atmosphere. During storage as well as during ripening, fruit stored in MAP exhibited a higher rate of respiration compared with other treatments. MAP exacerbated the effect of 1-MCP in reduction of ethylene production and fruit softening. 1-MCP application in combination with MAP after 5 and 7 weeks of storage delayed the fruit ripening by 10 and 8 days in contrast with control fruit, respectively. During storage, and as well as in ripe fruit, weight loss was reduced in fruit stored in MAP either with or without 1-MCP application. Control fruit and 1-MCP-treated fruit, stored in a normal atmosphere or in MAP, had the same values for the following parameters: chromaticity value L*, C*, and hue angle, titratable acidity, and concentrations of soluble solids, ascorbic acid, and total antioxidants. In conclusion, 1-MCP application in combination with MAP can be used effectively to reduce the ethylene biosynthesis and fruit softening during cold storage and to extend the storage life up to 7 weeks followed by 8 d of ripening without any adverse effects on the quality of ripe fruit.

Strawberries are valuable because of their nutritional value, but they are also highly perishable fruits. Fungal decay is the overriding factor that alters the overall quality of fresh strawberries. Because no hygienic treatments to reduce the initial microbial load are feasible, molds develop during postharvest when using conventional packaging. In this study, an antifungal packaging system for strawberries was developed to improve safety and quality. Trans-2-hexenal (HXAL), a natural compound in strawberries, was incorporated into the modified atmosphere packaging (MAP) systems. Zero, 100, and 250 µL of HXAL were included in cellulosic pads and were covered with a polyamide coating to control its release. The pads were placed on the bottom of plastic trays; an amount of250 g of strawberries was added, flow packed in micro-perforated PP bags, and stored at 4 °C for 14 days. Fungal infection was monitored during the storage period, and the optical and textural properties of the strawberries were measured at days 0 and 14. Analysis of the package headspace was conducted to check for the HXAL concentration. HXAL was partially retained in the fruits and was converted into hexyl acetate and 2-hexen-1-ol acetate, but this was only measurably present in the headspace of the active systems. Mold growth was fully inhibited in active packaging although the strawberries were softer and darker than those in the control packages. The active package was not as efficient if the fruits were stored under thermal-abuse conditions (15 and 22 °C).

Green garlic leaves are consumed as fresh and cooked in Turkey and in some part of the world such as Asia, America and Africa. This crop could be considered as a promising export product in Turkey’s exportation volume. For this reason, we investigated how different package materials such as low-density polyethylene (LDPE) and closed polypropylene transparent boxes (CPTB) maintain some quality parameters of green garlic (Allim sativum L.) leaves. For that purpose, garlic leaves were stored at 10 °C and 80±5% relative humidity for 12 days after cutting, pre-cooling and packaging. Weight loss (WL),  soluble solids content (SSC), titratable acidity (TA), chlorophyll content as SPAD reading, visual quality (VQ), color, total phenolic content (TPC) and total antioxidant capacity (TAC) were measured at 3, 6, 9 and 12 days during storage period. Our results indicated that both packaging materials significantly maintained (P ≤ 0.05) WL, TA, chlorophyll content, VQ and TPC compared to controls (unpacked samples). Pearson Correlation tests showed that WL, color (L*, b*), TA and TAC could be used as marker to determine storage life of green garlic leaves. In addition, CPTB package is more effective in maintaining quality of green garlic leaves during cold storage.

Fresh-cut potatoes were treated with an antibrowning solution (l-cysteine-citric acid mixture) and chlorine solutions, and then packaged under a modified atmosphere. The effect of these treatments on the microbiology of the potatoes was evaluated. Dipping the potato strips in sodium hypochlorite solutions (100 and 300 ppm) resulted in higher microbial populations during the storage period, while potatoes treated with the antibrowning solution combined with modified-atmosphere packaging showed only a slight increase. Modified-atmosphere packaging had no significant-effect on the microbial population compared to nonpackaged samples. The predominant organisms were Pseudomonas fluorescens, along with other Pseudomonas species, and Vibrio fluvialis.

The effects of combinations of modified atmosphere packaging (MAP) with potassium permanganate (KMnO4) based ethylene scrubbers on the storage life and fruit quality of nectarine (Prunus persica cv. Bayramiç Beyazı) were investigated. Three different types of ethylene sachets (contained 3, 7 and 10 g KMnO4) were used and placed beside fruits in polypropylene baskets then lined with MAP. Fruits were stored at 0-1°C and 90% relative humidity throughout 40 day. During the cooling storage period, O2 and CO2 percentage in MAP, fruit firmness, total soluble solids, titratable acidity, ascorbic acid, total flavonoid content, total phenolic content, total antioxidant content and chilling injury (CI) were determined at 10 day interval. KMnO4 treated fruits had shown delayed ripening, reduced respiration and retained of higher firmness. As the dose of KMnO4 treatment increased, it was determined more positive effect on fruit quality. 10 g KMnO4 treatment was most effective in the retention of higher biochemical compounds and inhibition of CI symptoms. The results indicate that KMnO4 treatment, as well as MAP application, should be highly recommended for retaining the fruit quality of cold-stored ‘Bayramiç Beyazı’ nectarines and fruits treated with 10 g doses of KMnO4 could be stored for 40 days with good quality.
