Effects of high voltage electric field on storage life and antioxidant capacity of whole pomegranate fruit

The objective of this study was to investigate the effects of high voltage electric field (HVEF) on the antioxidant system in stored pomegranate fruit. The experiments were conducted at cold storage for two months under three selected electric field levels (0, 1.5 and 3 kV/cm). Results showed that non-enzymatic antioxidant contents including phenols and ascorbic acid were better preserved by 1.5 kV/cm treatment than control after 60 days of storage. While the activities of superoxide dismutase (SOD), catalase (CAT), and ascorbate peroxidase (APX) in pomegranate fruit were significantly enhanced with 1.5 kV/cm treatment compared to control, Guaiacol peroxidase (G-POX) levels in the control group increased steadily and were highest at the end of the storage. Although the results obtained from 3 kV/cm treatment were acceptable till the end of the first month, due to oxidative damage of reactive oxygen species (ROS) produced in response to HVEF stress, their results come close to the control group at the end of the second month. These data suggest that the optimum electric field intensity for enhancing antioxidant contents in stored pomegranate fruits was 1.5 kV/cm.

The product Aonla (Emblica officinalis Geartn), the king of arid fruits, popularly known as “Indian gooseberry”, is a small-sized minor subtropical fruit grown widely in North India. India ranks first in the world in aonla area and production volume. It is considered to be a “wonder fruit for health” because of its unique properties. Uses. Aonla fruit is very useful in treating many diseases such as diabetes, cough, asthma, bronchitis, headache, dyspepsia, colic, flatulence, skin diseases, leprosy, jaundice, scurvy, diarrhoea and cancer. Packaging. Different packaging materials such as nylon net, perforated polyethylene bags, ventilated corrugated fibre boxes, gunny bags, wooden crates, etc., can be used for prolonging the storage life of fruit. Storage. Refrigerated storage helps in enhancing the storage life of fruit. Value addition. There are numerous products such as aonla squash, candy, jam, chutney, etc., which are pre- pared from aonla fruit. Inclusion of these products in the diet definitely helps in improving the nutritional value of Indian meals. Discussion. The low cost of the products as well as good sensory, nutritional and shelf life qualities mean that processed aonla products are appropriate for commercialization. In order to obtain a good income from aonla, it must be sold immediately in the market; if not, to make profit, proper storage facilities should be available.

Genome-Wide Identification of the 1-Aminocyclopropane-1-carboxylic Acid Synthase (ACS) Genes and Their Possible Role in Sand Pear (Pyrus pyrifolia) Fruit Ripening

Ethylene production is negatively associated with storage life in sand pear (Pyrus pyrifolia Nakai), particularly at the time of fruit harvest. 1-Aminocyclopropane-1-carboxylic acid synthase (ACS) is the rate-limiting enzyme in ethylene biosynthesis and is considered to be important for fruit storage life. However, the candidate ACS genes and their roles in sand pear remain unclear. The present study identified 13 ACS genes from the sand pear genome. Phylogenetic analysis categorized these ACS genes into four subgroups (type I, type II, type III and putative AAT), and indicated a close relationship between sand pear and Chinese white pear (P. bretschneideri). According to the RNA-seq data and qRT-PCR analysis, PpyACS1, PpyACS2, PpyACS3, PpyACS8, PpyACS9, PpyACS12 and PpyACS13 were differently expressed in climacteric and non-climacteric-type pear fruits, ‘Ninomiyahakuri’ and ‘Eli No.2’, respectively, during fruit ripening. In addition, the expressions of PpyACS2, PpyACS8, PpyACS12 and PpyACS13 were found to be associated with system 1 of ethylene production, while PpyACS1, PpyACS3, and PpyACS9 were found to be associated with system 2, indicating that these ACS genes have different roles in ethylene biosynthesis during fruit development. Overall, our study provides fundamental knowledge on the characteristics of the ACS gene family in sand pear, in addition to their possible roles in fruit ripening.

Effect of Postharvest Application of Edible Coatings and Packaging on Acid Lime Fruit var. SunKagati 1 Quality at Ambient Storage Condition

Sunkagati-1 is one of the commonly grown acid limes recommended for terai region of Nepal with main season production from Shrawan to Poush. In recent year, area of acid lime is increasing while no appropriate technology of postharvest is available for it. An experiment was carried out with an objective to assess the influence of edible oil coatings and packaging on storage life of acid lime fruit. Fruits were harvested at physiologically mature stage with smooth and shiny appearance and treated with four edible oils (coconut oil, mustard oil, sesamum oil and castor oil), liquid paraffin 10% wax emulsion and 25 micron low density polyethylene (LDPE) packaging. The study was conducted in completely randomized block design (CRD) with seven treatments and three replications. Fruits were kept at ambient condition (20±1.55 ºC, 65±6.5 % RH) till 24 days and analyzed for various postharvest physical, chemical and physiological parameters after 8th, 16th and 24th days of storage. The result showed that LDPE packaging has significant effect on reduction of physiological loss in weight (1.69 %), spoilage loss (5.17 %), higher vitamin C content (60.11 mg/100g), Titratable acidity (6.71 %) and development of marketable color viz., 100% yellow color. Also, coconut oil showed significantly better postharvest quality retention with reduced physiological loss in weight (10.83 %) and spoilage loss (10.45 %). This study concluded that LDPE packaging and coconut oil coating are the appropriate method to extend the storage life of acid lime in ambient condition of mid hills situation.

Grape Seed and Skin Extracts as Natural Preserving Agents on Strawberry Fruit

Concerning highly restricted application of chemicals in postharvest technology of horticultural crops, it is necessary to introduce the safe methods for preserving food or methods of food preservation. This study aimed to improve quality and prolong storage life of strawberry fruit by application of grape seed and fruit skin extracts and to compare them with calcium chloride as a chemical. In this study, strawberry fruit was individually immersed in the 1% and 2% CaCl2 solutions, seed and skin extracts (1 and 2 mg L-1) and then placed in polyethylene packaging for 24 d at 5±1 °C. Measurements of firmness, titrable acid, pH, weight loss, total antioxidant capacity, total phenolic, anthocyanin, vitamin C, enzymes' activity including catalase, peroxidase, and polyphenol oxidase and decay were carried out at 0, 6, 12, 18, and 24 d of storage. All applied treatments caused a significant effect on measured parameters including weight loss, titratable acidity, decay percentage and firmness, maintenance of anthocyanin and vitamin C contents, total phenolic, and antioxidant capacity. However, grape skin extract and grape seed extract showed the best results. Therefore, it can be concluded that Shiraz dark grape seed and skin extracts have the potential to control the decay incidence, prolong the storage life and preserve of postharvest valuable attributes of strawberry.

Improving Fruit Quality, Bioactive Compounds, and Storage Life of Date Palm (Phoenix dactylifera L., cv. Barhi) Using Natural Elicitors

“Barhi” date fruit is highly appreciated and widely consumed at the Bisr stage (first edible stage) of maturity. However, maintaining its quality for long periods of time after harvest and throughout marketing is a substantial challenge. Therefore, the objective of this study was to investigate the effects of preharvest spray treatments of 1% chitosan (Ch) in conjunction with 3% calcium chloride (Ca) and 2 mM salicylic acid (SA) on “Barhi” fruit’s shelf life, quality, and phytochemical composition at harvest and during cold storage. All treatments significantly delayed the ripening and decay of “Barhi” dates compared to controls. Ch treatment, followed by Ch + SA and Ch + SA + Ca, showed the lowest weight loss. Ch + Ca, Ch + SA + Ca, and Ch + SA treatments showed significantly lower levels of total soluble solids (TSS) compared to the control fruit. Ch + Ca and Ch + Ca + SA treatments showed no decayed fruit after 60 days of cold storage. At the end of storage time, the Ca treatment, followed by Ch + Ca + SA, showed the greatest total phenolic (TPC), flavonoids (TFC), and tannin (TTC) contents. Ch + SA + Ca, Ch + SA, and Ch showed significantly higher antioxidant and antimicrobial activities compared to controls. Based on these findings, these treatments may be recommended to prolong the shelf life of “Barhi” date fruit.

A COMBINED METHOD OF POST-HARVEST HANDLING OF SWEET CHERRY FRUIT VERSUS FRUIT STORABILITY

The objective of the research was to determine an optimum method of postharvest handling of sweet cherry fruits which may contribute to prolonged shelf-life. The following physical factors were examined – storage temperature: 2–4°C, 6–8°C, 18–20°C; postharvest fruit packaging and treatment: Xtend® CH-49 bags + no exposure to UV-C, Xtend® + exposure to UV-C for 120 s or 600 s, no bagging + no exposure to UV-C, no bagging + UV-C for 120 s or 600 s. UV-C irradiation, regardless of the duration and storage conditions, prolonged the storage life of sweet cherry fruit. During the 14-day period of storage, the smallest weight loss as well as the highest number of fruits suitable for consumption were found after exposure to UV-C for 600 s in both Xtend® bags and flat, exposed polyethylene containers. After 28 days, higher amount of fruits suitable for consumption were found after storage at 2–4°C than at 6–8ºC. The most advantageous postharvest treatment method was placing fruits in containers and irradiating them with UV-C for 600 s. However, statistically similar results were obtained also after packing the fruits in Xtend® bags and irradiating them with UV-C for 600 s as well as placing them in containers and irradiation with UV-C for 120 s. In addition, UV-C irradiated fruits for 120 s and 600 s contained significantly more reducing sugars than non-irradiated fruits after 14 days of storage. UV-C irradiated fruits for 600 s also contained the greatest amount of flavonoids. After 28 days of storage, the highest content of flavonoids and phenols was determined in UV-C exposed fruits stored in containers. In addition, it emerged that storing sweet cherry fruit at 2–4°C without bagging contributed to increased total phenolic content compared with fruit stored in Xtend® bags. Packaging cherry fruit in Xtend® bags is the most reasonable when it stored at 6–8°C and at room temperature.

Estimation storage life of blueberry fruits of different taxons

Based on the results of 12-year studies, the taxonomic characteristics of the keeping quality of berries of 27 cultivars end species of blueberries introduced in Belarus are shown. It was found that the storage postharvest of blueberry fruits under conditions of an ordinary gas atmosphere, depending on the taxon, varied from 7 days (swamp blueberry) to 29 days (‘Darrow' blueberry) at a storage temperature of +5 °C. Among the studied blueberry species, the fruits of tall blueberries and varieties obtained on the basis of this taxon retained their commercial qualities for a much longer period of time, compared to berries of other blueberry species. Fruits of late-ripening tall blueberry cultivars lose weight more slowly during storage and, accordingly, have a longer shelf life compared to berries of early-maturing taxa. The fruits of large-fruited blueberry cultivars are stored longer than the berries of small-fruited taxa of this crop. The keeping quality of blueberry berries, regardless of their taxonomic affiliation, was determined mainly by the natural loss of weight and, to a lesser extent, by waste from functional disorders and rot.

Effect of Methyl Jasmonate, Cytokinin, and Lavender Oil on Antioxidant Enzyme System of Apricot Fruit (Prunus armeniaca L.)

Various treatments are carried out in order to extend both the shelf life and storage life of fresh fruit and vegetables after harvest and among them non-toxic for humans, environmentally and economically friendly alternative treatments are gained more importance. In the current study, methyl jasmonate (MeJA), cytokinin, and lavender oil which are eco-friendly and safe for human health were applied on apricot fruit. The treated fruit were stored at 0 °C and 90–95% relative humidity for 25 days and catalase (CAT), superoxide dismutase (SOD), and ascorbate peroxidase (APX) enzyme activities and lipid peroxidation of apricots after treatments were studied. According to the findings obtained from the study, it was observed that 5 ppm cytokinin and 1000 ppm lavender oil treatments of apricot fruit gave better APX and CAT enzyme activity, respectively. In addition, better SOD enzyme activity in fruit was obtained with MeJA + lavender oil treatments. As a result, it can be emphasized that the product quality of apricot fruit is preserved as both the eco-friendly application of MeJA, cytokinin, and lavender oil separately from each other and the treatment of combinations between these compounds activate the enzymatic antioxidant defense systems of apricot fruit after harvest.

Short‐term hypobaric treatment enhances chilling tolerance in peaches

Peach fruit quickly shows symptoms of chilling injury (CI) during shelf life after storage under inadequate temperatures. We found that short-term hypobaric treatment (SHT) was effective in reducing the CI index to maintain the quality of peaches (Prunus persica L. Batsch cv. Yingshuanghong) during shelf life after cold storage. The respiration rate of peaches was inhibited, and the climacteric peak was delayed during storage after being treated at 0.45 atm pressures for 4 hr at 20°C. Meanwhile, SHT fruits maintained higher disaccharide concentrations and lower monosaccharide concentrations. SHT fruits also exhibited higher antioxidant enzyme activity that likely reduced the production of ROS. In addition, SHT suppressed membrane oxidation effectively by inhibiting phospholipase D (PLD) and lipoxygenase (LOX) activity to prevent malondialdehyde (MDA) accumulation. These results indicated that SHT performed effectively to alleviate CI in peaches by modulating respiration and sugars metabolism, oxidative stress, and membrane oxidation. Practical applications Unlike hypobaric storage for long periods of time, short-term hypobaric treatment (SHT) is a short-term application of subatmospheric pressure. This paper suggests that SHT is an effective method to alleviate CI and to maintain quality of peaches after cold storage. This work will help to expand chilling-sensitive fruit storage life to satisfy market and consumer demands.

Effect of Packing System, Calcium Chloride and Chlorine on the Storage Life of Strawberry Fruits (Fragaria ananassa cv. Kordistan)

Effect of packing system, calcium chlorite and chlorine was evaluated on storage life of strawberry fruits. Fruits were treated with commercial grade of chlorine (calcium hypochlorite at 0, 25, 50 and 100 ppm and sodium hypochlorite at 0, 25, 50 and 100 ppm with distilled water) for one minute and then treated with different grades of calcium chlorite 0, 0.5, 1 and 1.5 percentage for five minutes, then were divided to two groups; packed and non packed with plastic cover. Then fruits were evaluated for changes in quantity parameters; pH, TA (Titratable acidity), TSS (Total soluble solids), Dry and fresh weight ratio, water content, Anthocyanin, Ascorbic acid, Ca2+, Sugar and pectin. The results showed that the packed fruits treated with calcium chloride (at 0.5 and 1 percentage) and chlorine (at 50 ppm) remained better when compared with non packed fruits. It was found that packing treatment had not a significant effect on pH. It can also deduce that packed treated fruits showed a lower TA, Anthocyanin, calcium, sugar and pectin while TSS, fresh to dry weight ratio, water content and ascorbic acid was higher in packed treated fruits.

Effect of Chitosan–Pullulan Composite Edible Coating Functionalized with Pomegranate Peel Extract on the Shelf Life of Mango (Mangifera indica)

The polysaccharide based composite biomaterial (coating) used in preserving fruits and vegetables during storage is attracting increased attention as it is biodegradable material that prolongs shelf life. In the present investigation, chitosan–pullulan (50:50) composite edible coating was prepared with pomegranate peel extract (0.02 g/mL) as an active antioxidant agent. The effect of treatment with pomegranate peel extract enriched chitosan–pullulan composite edible coating on the shelf life of mango fruits during 18 days of storage period at room (23 °C) and cold (4 °C) temperature was evaluated. Results of the present study demonstrated that the application of chitosan–pullulan composite edible coating significantly (p ≤ 0.05) influences the storage life of mango fruits at both storage temperatures. The chitosan–pullulan composite edible coating reduced the physiological loss in weight (PLW), and maintained total soluble solids (TSS), acidity and pH of coated mango fruits as compared to the control. In addition, fruit sensory quality such as freshness, color, taste and texture were also retained by the treatment. Furthermore, sustained firmness, phenolic content and antioxidant activity confirmed the effectiveness of the pomegranate peel extract enriched chitosan–pullulan composite edible coating on mango fruits. The phenolic, flavonoid and antioxidant activity of coated fruits were retained by pomegranate peel rich edible coating. Therefore, the chitosan–pullulan (50:50) combination with pomegranate peel extract can be used as an alternative preservation method to prolong the shelf life of mango fruits at room and cold storage conditions. However, more in-depth studies are required at farm and transit level without affecting the postharvest quality of mango fruits, providing more revenue for farmers and minimizing postharvest losses.

Synergistic Effect of Preharvest Spray Application of Natural Elicitors on Storage Life and Bioactive Compounds of Date Palm (Phoenix dactylifera L., cv. Khesab)

Despite the immense capabilities of the date palm, maintaining the fruit’s quality, marketability, and shelf life is still a challenge. This study aimed to assess the synergistic effect of a preharvest spray application of a natural elicitor chitosan, (Ch) 1% alone and in combination with salicylic acid (SA) 2 mM and calcium chloride (Ca) 3%; (Ch,SA, Ca,Ch+Ca, Ch+SA, Ch+SA+Ca), on the quality parameters, storage life, and bioactive compounds content of date fruit from ‘Khasab’ cultivar during cold storage for 60 days. The obtained results revealed that all treatments significantly retard senescence/decay of the fruit compared to the control. Ch+SA treated fruit followed by Ch, and Ch+SA+Ca had the lowest weight loss, color change, and the least decay after 60 days of storage. Ch+Ca, SA, Ca treated fruit had significantly lower levels of total soluble solids and highest total phenolic, tannins, and flavonoids contents compared to the control fruit. Antioxidant activities were found in all treatments, with significantly higher effect in Ch+SA+Ca and Ch+SA compared to the control. Our results provide an evidence for a synergistic effect of elicitors combination to extend the shelf life of date fruit during cold storage by preserving its quality and decreasing senescence/decay and recommend it as a promising strategy.

Effects of Calcium Treatment on Physical and Biochemical Changes of Cold-Stored Sweet Cherry Fruit

In the present study, sweet cherry fruit (Prunus avium cv. 0900 Ziraat) were dipped into calcium (Ca) gluconate (calcium concentration of 1.5%) and distilled water (as control). The treated fruit were stored at 1 ± 0.5°C and 90% relative humidity for 4 weeks in two different packages. At weekly intervals, weight loss, fruit firmness, colour changes, soluble solids content, titratable acidity, sensory analysis, total phenolic and anthocyanin content of fruit and total chlorophyll content of stem were evaluated. As a result, Ca treatment positively affected sweet cherry fruits by maintaining firmness and decreasing respiration rate of sweet cherry fruit. Moreover, Ca treatment generally delayed the skin browning, and maintained fruit quality. Stem chlorophyll decomposition was retarded with Ca throughout cold the storage. Considering the sensory analysis, storage life of fruit could be prolonged at least up to 1 week by Ca1 (treated Ca-Glu and stored in plastic box with lid) treatment compared to other treatments.

Salicylic acid and oxalic acid in enhancing the quality and extending the shelf life of grape cv. Thompson seedless.

Postharvest life of table grapes is usually shortened by berry softening, berry drop, stem browning, fungal decay. Salicylic acid reduces fruit respiration and ethylene biosynthesis, during storage of fruits. Similarly, application of oxalic acid is a secure and hopeful postharvest handling technology for keeping quality and prolonging storage life of fruit. To study the effect of Salicylic acid and oxalic acid in enhancing the quality and extending the shelf life of grape, the present investigation was conducted. The grape berries were treated with Oxalic acid (OA) (1, 2, 3, 4, and 5 mM) and Salicylic acid (SA) (0.5, 1, 1.5 and 2 mM). The treatments were compared within 16th days at an interval of 4 days. Among the treatments, SA (2 mM) showed superiority in different quality attributing characters like physiological loss in weight (PLW), berry firmness, rachis browning, berry appearance, fungal decay, berry shattering, TSS, ascorbic acid, titratable acidity, total sugars, reducing sugars, TSS: acid ratio, taste, overall acceptability and shelf life. Hence, SA (2 mM) can be used as an effective strategy for maintaining quality of table grapes.

Effects of postharvest ultraviolet-C treatment on shelf-life and quality of bitter gourd fruit during storage

The aim of this experiment was to study the effect of varied UV-C exposure time (20, 30, 40 minutes) on nutraceutical properties, defence-related compounds, and storage life of bitter gourd fruit. Treated fruit was stored in a cold room maintained at 10 °C temperature and 85–95 % relative humidity for 16 days. UV-C treatment for 40 min was found better in improving antioxidant activity by inhibiting DPPH to 57 %, increasing total phenols to 61 %, total carotenoid to 134 % and total chlorophyll to 61.9 % during 16 days of storage period in comparison with control. UV-C treatment for 40 min was unable to maintain ascorbic acid and reduced its level to 15 % as compared to control on 16th day of storage. UV-C 40 min treatment has also shown positive effects in maintaining fruit firmness, reducing weight loss and fruit decay percent. Longer exposure to UV-C seems to enhance the abiotic stress level in bitter gourd fruit and it leads to the formation of defence-related compounds like MDA and proline. These compounds conjoin stored fruit in alleviating stress and maintaining a higher concentration of secondary metabolites. This suggests that the application of UV-C for 40 min can be gainfully utilized for enhancing shelf-life and retaining desirable quality parameters during storage of bitter gourd fruit.

Principles and Prospects of Prunus Cultivation in Greenhouse

Throughout history, new strategies and technologies have played a key role in promoting the development of agriculture. New strategies have led to substantial improvements in crop productivity and fruit quality. The cultivation of peach and apricot in controlled greenhouse conditions is one such strategy. The aim of the protected cultivation of these species in greenhouses is to grow fruit trees by modifying the natural environment of the tree, including the harvest duration, which can be extended. This protected cultivation should improve yield, thus increasing the benefit–cost ratio, especially in the case of organic production. Here we review the main factors involved in greenhouse fruit tree cultivation, including the planting systems and substrate, cultivar and rootstock selection, pollination management, orchard management, and environmental management. Greenhouse cultivation makes it possible to control environmental conditions like wind speed, moisture, temperature, mineral nutrients, light intensity, and the atmospheric composition, and thus gives us a better understanding of growth factor requirements, and the means to improve fruit productivity. A protected environment has been shown to be effective in maintaining a relatively high temperature and preventing leaf injury due to environmental factors, resulting in a longer period of photosynthetic activity, which increases the photosynthetic production, and is therefore a suitable alternative strategy for production in cold regions. The main benefits of apricot and peach cultivation in greenhouses are: (1) precocity; (2) high fruit quality, storage life, and market proximity; and (3) good plant health, suitable for organic cultivation. However, the main limiting factors for fruit tree production in greenhouse conditions to take into account are: (1) light scarcity at high latitudes; (2) a lack of cold for bud breaking, flowering, and fruit production; (3) potentially excessive temperatures in warm regions, which reduce the photosynthesis rate; and (4) a reduction of fruit quality, coloring, and aroma compounds in certain warm conditions with light day/night temperature variations.

Biodegradable Cellulose Film Prepared From Banana Pseudo-Stem Using an Ionic Liquid for Mango Preservation.

The excessive use and disposal of plastic packaging materials have drawn increasing concerns from the society because of the detrimental effect on environment and ecosystems. As the most widely used fruit packing material, polyethylene (PE) film is not suitable for long-term preservation of some tropical fruits, such as mangos, due to its inferior gas permeability. Cellulose based film can be made from renewable resources and is biodegradable and environmental-friendly, which makes it a promising alternative to PE as a packaging material. In this study, cellulose film synthesized from delignified banana stem fibers via an ionic liquid 1-Allyl-3-methylimidazolium chloride ([AMIm][Cl]) were evaluated as packing material for mangos preservation. The moisture vapor transmission rate and gas transmission rate of the synthesized cellulose film were 1,969.1 g/(m2⋅24 h) and 10,015.4 ml/(m2⋅24 h), respectively, which are significantly higher than those of commercial PE films. The high permeability is beneficial to the release of ethylene so that contribute to extend fruit ripening period. As a result, cellulose film packaging significantly decreased the disease and color indexes of mangos, while prolonged the storage and shelf life of marketable fruits. In addition, the cellulose film was decomposed in soils in 4 weeks, indicating an excellent biodegradability as compared to the PE plastic film.

Impact of chitosan in combination with potassium sorbate treatment on chilling injury and quality attributes of pomegranate fruit during cold storage.

The impact of chitosan (CH) and potassium sorbate (PS) on quality attributes of pomegranate fruits (cv. Malas e Saveh) was evaluated during 90days of storage at 4°C and 85%-90% relative humidity. The CH as well as the combined treatments (CH+PS) were effective in decreasing the chilling injury (CI) symptoms, electrolyte leakage, and malondialdehyde contents of fruit peel. Furthermore, CH, PS, and CH+PS treatments enhanced the activity of DPPH radical scavenging, and antioxidant enzymes of arils, and preserved the ascorbic acid content at high levels during the storage period. Fruits treated with CH1% + PS10% and CH2% + PS10% exhibited the lowest decay incidence and weight loss. Higher content of arils' phenols, flavonoids, and anthocyanin was observed in treated-fruits as a result of more activity of phenylalanine ammonia-lyase (PAL) and low activity of polyphenol oxidase (PPO). Consequently, CH+PS showed positive effects on the storage life of pomegranate fruits in terms of CI, decay incidence, and also nutritional values. PRACTICAL APPLICATIONS: Enhancement of chilling tolerance of pomegranate fruits during cold storage condition is a crucial issue. Application of CH coating alone or in combination with potassium sorbate could decrease the CI symptoms and preserved peel cell membrane integrity by maintaining electrolyte leakage (EL) and malondialdehyde in lower levels. Also, these treatments prevent weight loss and decay incidence in peel, and increase the activity of phenylpropanoid pathway and antioxidant systems in arils. All in all, usage of CH edible coating (2%) plus PS (10%) illustrated high efficiency in alleviating CI, decay incidence, and preserving nutritional quality of pomegranate fruits.
