Strawberry (Fragaria x ananassa Duch.) fruits are highly perishable which lose their marketability within a short period of time, resulting in considerable loss of fruits after harvest. In present study, the packaging materials treatment i.e. polypropylene terephthalate (PET) Punnet and High density polythene (HDPE) crates and calcium compounds (CaCl2 and Ca(No3)2) were examined for the storability and biochemical quality of strawberry (cv. Winter Down) fruits in cold condition (3±1 °C) in comparison to the untreated control fruit in ambient storage for 3, 6 and 8 days storage period. Results revealed that physiological loss in weight (PLW) and fruit decay increased with the advancement of the storage period irrespective of the treatments. Fruits treated with CaCl2 (2%), packed in PET Punnets and stored in cold condition (3±1 °C) showed significantly minimum PLW (6.55, 11.12 and 15 34 %) and fruit decay (7.29, 17.71 and 34.38 %) at 3, 6 and 8 days storage, respectively. Non-treated control fruits at ambient conditions could not maintain their marketability even 3 days of storage and showed relatively high decay losses (25.00, 62.21 and 91.67 % at 3, 6 and 8 days of storage, respectively). Packaging and calcium treatment did not affect the fruit total soluble solids (TSS) and total sugars but was found effective to slow down the decrease of ascorbic acid and acidity contents of the fruit during storage. PET Punnets packaged fruits treated with CaCl2 (2%) under cold conditions retained better shelf-life with better biochemical quality of fruits during storage while untreated control fruits deteriorated rapidly.

Both Cacl2 and Nutrical (a trihydroxyglutarate chelate) were foliarly applied at rates of 1.8 and 5.5 Cacl2/ha/season and 1.5 and 4.5 l/ha/season, respectively. Applications were made starting at shuck split and repeated at 2 week intervals until harvest. Neither calcium treatment had an effect on fruit size and size distribution. Fruit size was directly related to crop load. Calcium chloride application had the most pronounced effect on increasing the red over-color of `Cresthaven' peaches with Nutrical intermediate compared to the control. The high rate of Nutrical increased flesh calcium levels at harvest by 75-100 PPM. Instron Texture Profile Analysis indicated that any calcium treatment significantly increased the hardness of the peach. Nutrical at 4.5 l/ha/season improved hardness 2-fold compared to the controls. The improved hardness was maintained throughout the 6 week storage period.

The study was carried out to minimize the postharvest loses and extend shelf life of mango fruitby maintaining physico-chemical properties. The variety selected for the study was “Amrapali”. Freshly harvested mango was treated with different concentrations (20% and 40%) of neem leaf and banana pulp extract alone or in combination. Untreated mango was considered as control. All treated and untreated mango was kept into paper cartons at room condition. The treated fruits showed significant differences in case of total soluble solids content, titratable acidity, vitamin C, disease incidence, disease severity and shelf life in comparison to control fruits. Among the treatments, T2 (neem leaf extract at 20%) and T5 (neem leaf extract 40% + banana pulp extract 40%) treatments showed longer shelf life (9.92 and 10.25 days, respectively), slower changes in color (score 2.77 and 2.93, respectively) and firmness (score 2.67 and 2.77, respectively); less disease severity (score 2.93 and 3.57, respectively), disease incidence (46.67% and 60.00%) and lower loss in weight (38.04% and 35.17%, respectively) at 9 DAT (Days after treatment). On the other hand, total soluble solid was highest in T3 (neem leaf extract 40%) treated fruitswith18.73% more Brix at 13 DAT in comparison to control and other treatments. The effectiveness of the treatment T5 (neem leaf extract 40% + banana pulp extract 40%) was meaningful which could be recommended for maintenance of postharvest quality of mango stored in ambient conditions.

Tomato (Lycopersicon esculentum Mill.) fruits, cv. Santa Clara, were harvested at the breaker stage from commercial fields in Brazlândia, Brazil, to investigate the ability of 1-methylcyclopropene (1-MCP) to retard tomato fruit ripening. Fruit without external blemishes were graded for size (diameter = 80±5 mm) and mass (m = 130±10 g), placed inside hermetically sealed boxes, and 1-MCP was applied for 12 hours (T = 22±1°C; RH = 80-85%) at four different concentrations: 0 (control), 250, 500 and 1000 mL.L-1. Fruits were held at ambient conditions (T = 23±2°C; RH 80-85%) for 2 days and then stored inside a cold room (T = 20±1°C; RH = 85-95%). Every 3 days, during a 15-day period, fruits were analyzed for firmness, total soluble solids, titratable acidity, external color, and total carotenoids. Firmness of fruit treated with 1000 mL.L-1 was about 88% higher than control fruits after 17 days. The a*/b* ratio, an indicator of skin color, for fruit treated with 1000 mL.L-1 of 1-MCP was 38% lower than control fruits at the end of the storage period. Treatments with higher concentrations of 1-MCP delayed total carotenoids synthesis and color development. Control fruits stored for 17 days had about 190% more total carotenoids than fruits treated with 1000 mL.L-1 of 1-MCP. Postharvest application of 1-MCP was an efficient method to delay tomato fruit ripening. As 1-MCP concentration increased, ripening was further delayed. Tomatoes treated with 250, 500, and 1000 mL.L-1 of 1-MCP were delayed by 8 to 11, 11 to 13 and 15 to 17 days, respectively.

Aims:  To evaluate the potentiality of bio-extract coatings for achieving extended shelf life with enhance fruit quality attributes in pomegranate under ambient storage condition.  Study Design:  The lab experiment conducted in complete randomized design with three repetitions on Mridula cultivar of pomegranate.     Place and Duration of Study:  The experiment was conducted during September 2016 at department of fruit science, Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana, India. Methodology: Pomegranate freshly harvested fruits were coated with three bio-extracts coatings viz. Aloe vera (50,75 and 100%), ginger (1,2 and 3%) and mints (10,20 and 30%). The coated fruits were stored at ambient room condition in corrugated fiber board boxes for twelve days.  Periodically effects of bio-extract coatings, storage period and their interaction were observed for physiological loss in weight, decay loss, juice content, TSS: acid ratio, ascorbic acid content and anthocyanin content.    Results: Surface coating with Aloe vera extract 100% was found most effective in reducing physiological loss in weight (50% less reduction as compared to untreated control) whereas ginger extract 3% in reducing the decay loss of fruits (9.65%) as compared to untreated control (23.36%). Among various treatments, the coating of pomegranate fruits with Aloe vera extract 100% resulted in lowest total soluble solids to acid ratio (32.17%) and significantly highest content of juice (47.17%), anthocyanin (13.98 mg/100 g) and ascorbic acid (12.82 mg/100 g) of the fruits along with highest organoleptic rating. The quality attributes viz. total soluble solids to acid ratio, anthocyanin of fruits increased with progression of storage period, while juice content and ascorbic acid decreased. Conclusion: Bio-extract coating of Aloe vera (100%) substantially improved the shelf life with retaining better fruit quality attributes under ambient conditions and has the potential to substitute the prevalent chemical coatings for pomegranate.

An active packaging film (APF1) with releasing low concentration sulfur dioxide (SO2) was tested on quality of ‘vitis labruscana kyoho’ table grape. All samples were stored at 5°C and during the storage period the main quality parameters, weight loss, berries shatter, decay, firmness, total soluble solids content (TSS), total acid (TA, using the PH of grape juice instead of the TA ), Vitamin c (Vc) content were monitored and compared with the control sample unpacked in any film. Results demonstrated that APF1 could reduce water loss of table grapes, prevent it from pathogens infection. The results also showed that APF1 could greatly guarantee a long shelf life for grape. After storage 56 days (storage at 0~5°C), the water loss, berry firmness, TA and Vc content in grapes packaged in APF1 were slowly reduced, TSS was slight increased, percentage of shatter and decayed berries of grapes were 22% and 27%, respectively. The percentage of berries decay of grapes packaged in APF1 was reduced to 5% from 21% for control batches on 11th days. All unpackaged table grapes (control batches) were decayed after 28 days. APF1 would help to preserve quality and extend shelf life of table grapes.

Low O2 and high CO2 concentrations can be used effectively to slow respiration and retard decay, but anaerobic and C02-injurious conditions must be avoided. The objective of this research was to: 1) determine the effects of low O2 and very high-C02 on flavor quality and accumulation of fermentation products. Strawberries and blueberries were stored in 2% O2/0% CO2, 20% 02/50% CO2, 2% O2/50% CO2, and 20% 02/0% CO2 for 0, 2, 4, 6, and 8 days at 20C. A taste panel evaluated the berries at the end of each storage period and again after 2 days under ambient conditions. Ethanol was the primary fermentation product that accumulated in response to low O2 and high CO2 concentrations. However, acetaldehyde was produced preferentially in response to elevated C02 levels. The flavor quality of the strawberries and blueberries was only acceptable for 2 days for treatments containing 50% CO2. The most intense off-flavors were detected in the 2% 02/50% CO2 and 20% O2/50% CO2 samples. 50% CO2 was highly effective in preventing decay, but this concentration was too high for acceptable flavor quality for storage periods greater than 2 days.

AbstractIn this study, ‘Rabbab’ pomegranates (Punica granatum L.) were subjected before storage to single-layered wax coating (SLW), double-layered wax coating (DLW), individual-seal film packaging (ISP), tray wrap film packaging (TWP), and combined treatments of SLW + ISP or SLW + TWP. Treated fruits were then stored at ambient temperature (15–20 °C; 45–50% relative humidity – RH) or in cold conditions (5 °C ± 0.5; 85% RH) for 18 weeks. TWP, ISP, DLW, and SLW extended the shelf life of pomegranates for 18, 18, 12, and 11 weeks at cold (5 °C) condition, and also for 6, 5, 3, and 3 weeks at ambient condition, respectively, whereas the shelf life of control fruits were 10 and 2 weeks at cold and ambient conditions, respectively. After 18 weeks of storage, the weight loss in ISP and TWP fruits was 0.6 and 0.4% at cold condition and 12.4 and 5.4% at ambient condition, respectively. In general, film packaging maintained vitamin C, total titratable acidity, and sensory analysis scores for color, freshness, juiciness, and taste of pomegranates more effectively than wax coating and control. However, the combination of SLW and ISP or TWP did not improve the efficiency of pomegranates packaged as either ISP or TWP.

`Redcort Cortland' and `Redmax' and `Summerland McIntosh' apples (Malus ×domestica Borkh.) were treated with 900 nL·L-1 of 1-methylcyclopropene (1-MCP) for 24 hours at 20 °C before storage and were kept at 3 °C in either a controlled atmosphere (CA) of 2 kPa O2 and <2.5 kPa CO2 or in an air (RA) environment for up to 9 months. After 4.5 months, half of the fruit were treated with a second 900 nL·L-1 1-MCP application in air at 3 °C for 24 hours and then returned to RA or CA storage. At harvest and following removal at 3, 6, and 9 months and a 7-day shelf life at 20 °C, fruit firmness, titratable acidity (TA) and soluble solids content (SSC) were measured, while internal ethylene concentrations (IEC) in the apple core were quantified after 1 day at 20 °C. Upon storage removal and following a 21-day shelf life at 20 °C, disorder incidence was evaluated. 1-MCP-treated apples, particularly those held in CA-storage, were more firm and had lower IEC than untreated fruit. Higher TA levels were maintained with 1-MCP in all three strains from both storages, while SSC was not affected. Following the 6- and/or 9-month removals, 1-MCP suppressed superficial scald development in all strains and reduced core browning and senescent breakdown in RA-stored `Redmax' and `Summerland' and senescent breakdown in RA-stored `Redcort'. 1-MCP generally maintained the quality of `Cortland' and `McIntosh' fruit held in CA and RA environments (particularly the former) to a higher degree than untreated apples over the 9-month storage period. A second midstorage application of 1-MCP at 3 °C did not improve poststorage fruit quality above a single, prestorage treatment.

Mangoes of the Irwin, Edward, Palmer, and Keitt varieties were evaluated as to their quality for nectar. The pulp yields were 75.07, 76.85, 73.23, and 78.95%; and the soluble solids were 16.0, 21.2, 20.5 and 21.5° Brix, respectively. The quality of the canned nectars stored for as long as 12 months under ambient conditions was acceptable. Compared to the nectars of the other three varieties the variety of Keitt nectar was inferior in quality during the first three months and at the end of the study. During intermediate periods nectars from the Palmer and the Edward cultivars were superior.

The quality of three dragon fruit clones (Hylocereus spp.) was determined after x-ray irradiation for disinfestation of quarantine pests. Fruit were treated with irradiation doses of 0, 200, 400, 600, or 800 Gy and stored for 12 days at 10 °C. Irradiation did not affect soluble solids content, titratable acidity, or fructose concentrations. Glucose, sucrose, and total sugar concentrations decreased linearly as dose increased. Minimal softening occurred in the outer flesh layers for fruit treated with 400 or 600 Gy irradiation. Surface color, peel injury, and bract appearance differed among the three clones with irradiation stress, but in all cases, visible changes were minor. Fruit decay was absent or minimal, and disease ratings were not affected by irradiation. Irradiation treatment of dragon fruit at doses 800 Gy or less would ensure visual and compositional quality while providing quarantine security.
