Decay on mango (Mangifera indica) fruit mostly derived from a fungal disease which was caused by anthracnose invasion and infestation. The falling quality of mango fruit during postharvest preservation was commonly associated with weight loss, softening, vitamin C degradation and decay. This research evaluated the synergistic effect of methyl cellulose (MC) and carvacrol (Car) in the preparation of the edible coating on the physicochemical and microbial characteristics of mango fruit during 28 days of storage at 18°C. Five groups of coating treatments were prepared as follows: A (4% MC), B (4% MC + 0.5% Car), C (4% MC + 0.75% Car), D (4% MC + 1.0% Car), E (4% MC + 1.25% Car). These coating solutions were set 40°C for mango dipping. Mango fruits were individually dipped in the respected MC-Car solutions for 15 s and left out to air-condition for 30 min to create the coating film. These mango fruits were then kept at 18°C for 28 days. In 7 day-interval, experimental fruits were sampled to estimate weight loss, firmness, ascorbic acid content, decay index. Mango fruit pre-coated by 4% MC + 1.0% Car showed the least weight loss (1.61±0.03 %) and decay index (2.19±0.03 mark) while the highest retention of firmness (47.13±0.23 N) and ascorbic acid (25.60±0.13 mg/100 g) at the end of 28 days of storage. Results showed that incorporation of 1.0% carvacrol into 4% methyl cellulose-based edible coating would extend the shelf-life of mango fruit for 28 days of preservation. The edible coating would be a promising and green alternative with minimal environmental pollution.

Demand for minimally processed fruits have increased due to their nutritional value and an increasing change in consumption habits. Physicochemical, microbiological, structural and sensory changes were determined in minimally processed mangoes (MPM) with chitosan (CH) edible coatings and lemon and orange essential oils (EOL). The MPM was first dipped in citric acid and a texturizing solution and then dipped in CH and lemon or orange EOL coatings. Weight loss, sensory acceptance, total soluble solids, total acidity, ascorbic acid, color changes, firmness and elasticity, and microbiological changes were quantified for 11 days of refrigerated storage. The CH and lemon EOL coating had more acceptance than the other treatments. No differences were found (p>0.05) for weight loss, total acidity, ascorbic acid, firmness or elasticity. There was a high amount of total phenols due to the EOL composition, as well as a high antioxidant capacity in the early days of storage. This characteristic decreased in the final days of the study. There was a decrease in the microbial charge for the lemon EOL treatment, as compared to the other samples. The CH and lemon EOL coating helped to maintain the shelf-life of the MPM for 11 days of storage without affecting the sensory acceptance. The CH and Orange EOL coating did not have an effect on the MPM physicochemical attributes; however, the sensory acceptance was negatively affected with off-flavors conferred to the MPM.

Summary. Water loss and premature ripening during postharvest handling reduce the market quality of mango fruit. Towards investigating the use of moisture barrier liners for mango fruit trays, relationships between in-package relative humidity and weight loss and ripening of ‘Kensington Pride’ fruit were studied. Individual fruit were held at 20°C in sealed plastic containers (small 1.2 L buckets). The lid of each container had a single circular hole. Holes were of various sizes, ranging from 5 to 135 mm diameter. Ripening mature green fruit held at the lowest relative humidity of 57% (135 mm diameter hole) lost weight at a significantly (P£0.05) greater rate (10 mg/g initial FW. day) than fruit at higher relative humidities of 59 (open air), 60 (95 mm diameter hole), 61 (55 mm diameter hole), 71 (35 mm diameter hole), 74 (25 mm diameter hole) and 83% (25 mm diameter hole plus free water). These fruit at higher relative humidities lost weight at rates ranging between 9 and 4 mg/g initial FW. day. Fruit softening and skin colouring rates were similar across all relative humidities. In a second experiment, mango fruit were allowed to ripen in containers with smaller holes, ranging from 5 to 95 mm diameter, in their lids. Fruit at the lowest relative humidity (60%, 95 mm diameter hole) lost weight at a significantly (P≤0.05) greater rate (9 mg/g initial FW. day) than fruit from other treatments. Furthermore, these fruit ripened about 2 days sooner than fruit at higher relative humidities: 85 (25 mm diameter hole), 88 (15 mm diameter hole), 91 (10 mm diameter hole) and 93% (5 mm diameter hole). Fruit at the higher relative humidities lost weight at rates between 6 and 2 mg/g initial FW. day, and ripened in 6 to 12 days. Thus, hole size can be varied in order to control in-package relative humidity and regulate mango fruit weight loss and ripening. Australian Journal of Experimental Agriculture, 1997, 37, 463–7 463

The effect of applying Ca++ in two forms: infiltration and dipping on mango fruit cv `Haden' was investigated. This effect was evaluated by measuring some quality parameters in the flesh and in the skin of the fruit. It was found that postharvest application of Ca++ extent the storage life of the fruit by a week. This fact, together with the results obtained from the quantification of sugars, ascorbic acid, total soluble solids alcohol. insoluble solids, starch and titrable acidity seem to indicate that the application of Ca++ delays slightly the process associated with ripeness. Furthermore, no significant difference between the two forms of Ca++ applied was found, except for the amount of ascorbic acid and total sugar. Finally, dipping application of Ca++ is easier than infiltration and it is therefore suggested.

Spinach is a widely consumed leafy green vegetable, but it exhibits short storage life due to quick loss in moisture contents during postharvest period. The present study was aimed to evaluate the effect of blanching treatment and different types of packaging on spinach quality under cold storage conditions. Fresh spinach after treatment [T0 = control, T1 = blanching, T2 = modified atmosphere packaging (MAP-1, Xtend®), T3 = MAP-2 (Bio-fresh®) and T4 = perforated polyethylene (PE)] application was stored at 4±1 °C and 90±5 % RH for 20 days. Samples were analyzed at the time of harvest (0 day) and then after 3 days interval during storage. MAP treatments performed well and had a positive effect on spinach by maintaining its freshness and quality. Decay, ion leakage and weight loss were observed lower in spinach packed in MAP-1(Xtend®) followed by MAP-2 (Bio-Fresh®) and perforated PE packaging. MA packaging maintained higher ascorbic acid content, chlorophyll, and total antioxidants of spinach during storage. Nevertheless, spinach packed in perforated PE also displayed better results in maintaining quality as compared to control and blanched samples. The maximum weight loss, poor quality, minimum ascorbic acid content with lower consumer acceptability was recorded in control samples. Overall, MAP-1(Xtend®) could be used as a promising technology to maintain the quality of spinach up to 20 days of cold storage.

Cherry tomatoes are climacteric fruits that have a limited shelf life. Over the years, many methods have been applied to preserve the fruit quality and safety of these fruits. In this study, a novel method of combining mucilage from dragon fruits and UV-C irradiation was carried out. Cherry tomatoes were subjected to UV-C irradiation and edible coating, both as a stand-alone and hurdle treatment. The edible coating was prepared from the mucilage of white dragon fruits. Quality parameters including color, weight loss, total soluble solids, titratable acidity, ascorbic acid, antioxidant analysis (total phenolic content and flavonoid content), and microbial analysis were measured throughout 21 days of storage at 4 °C. Results showed that the hurdle treatment extended shelf life by 21 days, reduced weight loss (0.87 ± 0.05%) and color changes (11.61 ± 0.95 ΔE), and inhibited microbes better than stand-alone treatments. Furthermore, fruits treated with the combination of UV-C and edible coating also contained higher total polyphenol content (0.132 ± 0.003 mg GAE/100 mL), total flavonoid content (13.179 ± 0.002 mg CE/100 mL), and ascorbic acid (1.07 ± 0.06 mg/100 mL). These results show that the combination of UV-C and edible coating as a hurdle treatment could be an innovative method to preserve shelf life and quality of fruits.

In this study, the effect of postharvest salicylic acid (2 mM), oxalic acid (5 mM), putrescine (2 mM) and calcium (4% CaCl2) applications on storage performance of Autumn Giant plum fruit were investigated. After applications, plum fruits were placed in modified atmosphere packaging (MAP) and stored for 40 days at 85-90% relative humidity conditions at 0.5±0.5°C. In order to determine the fruit quality characteristics after treatments, weight loss, soluble solids content, titratable acidity, fruit firmness, ascorbic acid, total flavonoids, total phenolics and total antioxidant content analysis were performed at 10 days’ intervals. According to the results, the effect of applications on weight loss was not significant. The maximum decrease in flesh firmness, titratable acid and ascorbic acid content during storage was determined in control fruits. Although fluctuations in the form of increase or decrease in biochemical compounds were generally observed, decreases occurred according to harvest value at the end of storage period. Considering all measurements and evaluations, it was determined that application of salicylic acid and putrescine had a more positive effect on preservation of fruit quality properties and biochemical content of Autumn Giant plum cultivar during storage than other applications.

Tamarillo [Cyphomandra betacea (Cav.) Sendt., Solanaceae] dark-red-, red-, and yellow-type fruit were sorted into two maturity stages (green and turning); dipped in ethephon at 0, 250, 500, or 750 mg·liter–1; and kept at 18 or 28C. Seven days later, fruit dipped in ethephon at 500 or 750 mg·liter–1 and stored at 28C showed a color score, maturity index, and ascorbic acid content similar to those tree-ripened, thus making it possible for harvesting to be advanced 36 days. Under these conditions, weight loss was always lower than 8.5%, resulting in only slight symptoms of shriveling that did not affect commercial quality. Postharvest ripening reduces the risk of crop failure, increases earliness, and concentrates harvesting. Chemical name used: (2-chloroethyl)phosphonic acid (ethephon).

Five mangos cultivars (Mangifera indica L., `Palmer', `Keitt', `Spring Field', `Kent', and `Anderson') were harvested at the preclimacteric stage. Fruits were selected for study that were uniform and free of visual defects and stored for 18 days at 10 °C, 90% to 95 % RH. Fruits were evaluated every 3 days for pulp and peel color, total soluble solids, titratable acidity, ascorbic acid content, and total and reducing sugars. Pulp and peel color parameters (lightness, hue, and chroma) were significantly different among cultivars. The soluble solids content, ascorbic acid, and starch content changed significantly during storage and were significantly different among cultivars. Total and reducing sugars content did not change significantly after 10 days of storage. Results of this study indicated that these five mango cultivars have good storage potential.

Peach (Prunus persica L.) fruits exhibit limited postharvest shelf and storage life due to rapid softening. Therefore, in the present study effect of cold storage was investigated on postharvest chilling injury (CI) and fruit quality during ripening following cold storage on five peach cultivars including ‘Peach Select No. 3’ (PS-3), ‘Florida Gold’ (FG) and ‘Florida King’ (FK) as early season maturing, and ‘Indian Blood’ (IB) and ‘Maria Delezia’ (MD) as late season maturing cultivars. Peach fruits harvested at commercial maturity were ripened at ambient conditions following cold storage for 0, 10 and 20 days at 0±1 °C with 80±5% RH. Data regarding peach fruit quality parameters and incidence of CI were recorded at fully ripe eating soft stage. Results indicated that apart from the cultivars, fruit weight loss, levels of soluble solid content (SSC) and sugars increased as the storage period was progressed. However, fruit firmness, titratable acidity (TA), and ascorbic acid content significantly reduced during cold storage. Among early season maturing peach cultivars, fruits of ‘FG’ and among late season maturing peach cultivars, fruits of ‘MD’ showed better postharvest shelf life and fruit quality during ripening following cold storage. The highest SSC and SSC: TA ratio were observed in ‘FG’ peach fruits; however, these fruits exhibited 50% and 75% CI after 10 and 20 days of cold storage, respectively. During first 10 days of cold storage, ‘PS-3’ peach fruits showed better taste with higher fruit firmness and ascorbic acid content, however, later on the highest level of CI was observed in these fruits. Among all the tested peach cultivars, the ‘IB’ peach fruits showed higher fruit firmness, lower weight loss, as well as acceptable biochemical fruit quality (SSC, SSC; TA, ascorbic acid content, total sugars) during 20 days of cold storage without showing any symptoms of CI.

Physiology and quality of CaCl2 treated or nontreated `Elite' zucchini squash slices were monitored during storage in air, low O2 (0.25, 0.5 and 1%) or high CO2 (3, 6, and 10%) atmosphere at 10C. O2 consumption and CO2 production were reduced under low O2 and high CO2 atmospheres and the reduction was greater with low O2. C2H4 production was reduced with low O2 and initially with high CO2. After day 2 or 4, C2H4 production under high CO2 increased with the increase being greater at the lower CO2 level. The amount and severity of injury/decay were less under low O2 and high CO2 than air atmosphere. Slices stored under 0.25% O2 atmosphere had less weight loss and injury/decay and greater shear force and ascorbic acid content than those held in air atmosphere. Microbial count, pH, and color were affected by the low O2 only on the last day. CaCl2 had no additive effect.
