Today, the most significant challenge encountered by food manufacturers is degradation in the food quality during storage, which is countered by expensive packing, which causes enormous monetary and environmental costs. Edible packaging is a potential alternative for protecting food quality and improving shelf life by delaying microbial growth and providing moisture and gas barrier properties. For the first time, the current article reports the preparation of the new films from Ditriterpenoids and Secomeliacins isolated from Melia azedarach (Dharek) Azadirachta indica plants to protect the quality of fruits. After evaluating these films, their mechanical, specific respirational, coating crystal elongation, elastic, water vapor transmission rate (WVTR), film thickness, and nanoindentation test properties are applied to apple fruit for several storage periods: 0, 3, 6, 9 days. The fruits were evaluated for postharvest quality by screening several essential phytochemical, physiological responses under film coating and storage conditions. It was observed that prepared films were highly active during storage periods. Coated fruits showed improved quality due to the protection of the film, which lowered the transmission rate and enhanced the diffusion rate, followed by an increase in the shelf life. The coating crystals were higher in Film-5 and lower activity in untreated films. It was observed that the application of films through dipping was a simple technique at a laboratory scale, whereas extrusion and spraying were preferred on a commercial scale. The phytochemicals screening of treated fruits during the storage period showed that a maximum of eight important bioactive compounds were present in fruits after the treatment of films. It was resolved that new active films (1–5) were helpful in the effective maintenance of fruit quality and all essential compounds during storage periods. It was concluded that these films could be helpful for fruits growers and the processing industry to maintain fruit quality during the storage period as a new emerging technology.

Our purpose was to determine cultivar and culture system effects on yield and postharvest quality of greenhouse tomato Lycopersicon esculentum. Nine tomato cultivars were sown into rockwool cubes on 2 Feb. 1994. The plants were transplanted into peat bags or nutrient film (NFT) systems on 9 Mar. Harvesting began on 2 May until 26 Sept. for a total of 21 harvest weeks. Fruit yield, rejected or nonmarketable fruit and four fruit quality indicators (fruit texture, color, titrable acidity, and soluble sugars) were measured during the harvest period. In addition, these indicators were further evaluated every 7 days during 28 days of storage at 20C and 90% RH for `Trust' and `Cencara', a long shelf-life cultivar. `Bounty', `Panther', and `Cencara' gave higher yields on rockwool but `Irazu', `Correct', `73-53', and `Medallion' gave better results on NFT. `Trust' produced the best yield for either rockwool or NFT. Culture systems (peat bags or NFT) did not affect fruit quality. `Cencara', which is a long shelf-life cultivar, kept high texture quality until 28 days of storage. However, titrable acidity of `Cencara' was higher and soluble sugars content was lower than that of `Trust'

Selenium (Se) deficiency in humans could be improved by biofortification of food with selenium, 1-Methylcyclopropene (1-MCP) treatment is beneficial for the non-sulfur storage of fresh fruit. This study investigated fruit quality of table grape (Hutai No.8) with foliar Se fertilizer at maturity, and fruit quality changes of table grape during shelf life stages that caused by postharvest 1-MCP treatment in 2016 and 2017. The results showed that foliar Se fertilizer application significantly increased Se content in grape berries at maturity, and the raised rate were 43.09% and 33.24% compared to that of control in 2016 and 2017 respectively, meanwhile it increased the nutritional components in grape berries, including soluble proteins, soluble sugars, Vitamin C, total soluble solids, proanthocyanidin content and so on, and decreased the titratable acidity content. During shelf life stages, 1-MCP application decreased the decay number of grapes, and SE + 1-MCP treatment had the most excellent fruit quality among all treatments in two consecutive vintages. In conclusion, Se fertilizer application could increase Se content in grape berries, also improved the fruit nutritional and health care values at maturity. 1-MCP application could delay the process of ripening and senescence for Se-enriched grape and maintaining the postharvest quality of table grape during shelf life stages, it allows us to market the fruit at a more advanced ripening stage without quality loss.

Biopolymer-based coatings or films can be used as an alternative to the replacement of conventional packaging, to preserve fresh fruit quality and extend their shelf life. This study aimed to prepare and characterize biopolymeric coating films based on chitosan and carboxymethyl cellulose (CMC). Film coating of biopolymers was further applied on mango fruits, and the efficacy of coating materials in post-harvest shelf life and maintaining quality parameters of mango were then determined. The coating method of the films over mango was prepared using a dipping technique. Fruit weight loss, colors and content of total soluble solids were evaluated to assess fruit quality during 14 days at 25 °C of storage. Results indicated that films formulated with CMC showed significantly higher water solubility and water vapor transmission rate. Notably, coating improved the quality of mango during storage. Between the coating types, CMC was found to be significantly more effective in maintaining fruit fresh weight during the storage period. The fruit treated with CMC lowered the change in color and had higher soluble solids content than that of chitosan coating on the fourteenth day of storage. These results demonstrate that CMC-based coating could be utilized for the extension of the fruit commercialization period.

The ripening pattern of the climacteric type of the pinha (Anona squamosa L.) limits its shelf life at room temperature, in addition, storage at low temperatures develops cold sores on the fruit. Thus, the association of conservation technologies is fundamental to reduce the losses in the post-harvest of this fruit, so it was aimed to evaluate sachets impregnated with potassium permanganate (KMnO4) associated with refrigeration in the control of ripening and preservation of quality. For this, pinhas were harvested at physiological maturity, packed in polystyrene styrofoam trays coated with PVC film with and without the presence of sachets containing 3 g of KMnO4 and stored at 13 ºC for 20 days. Every five days the fruit quality was evaluated as: weight loss, cracking index, firmness, external appearance, starch content, soluble solids, titratable acidity, pH, ratio SS/TA, coloring (Hue, Chroma and Luminosity) and cold damage. The absorption of ethylene by the KMnO4 sachet inside the packages preserved significantly (p<0.05) the physical-chemical quality and the visual appearance of the fruits but did not influence the coloration (chroma and luminosity) and incidence of damage by cold in relation to its control at the end of the storage period. The packing of pinhas containing 3 g of KMnO4 is an alternative to delay ripening, prolong the shelf life without compromising the physical-chemical quality of the fruits.

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.

The present study evaluated the effect of NPK fertilizer (17:17:17) rates (0, 100, 200, 300 and 400 kg ha-1) on the postharvest quality of field and greenhouse grown pepino melons (Solanum muricatum Ait.) stored at room temperature (15-22°C) and at low temperature (7°C). The study was carried out in randomized complete block design with fruits from the field and greenhouse, five NPK fertilizer rates as treatments and the two storage temperatures replicated three times. Data were collected on percentage fruit weight loss (PWL), total soluble solids (TSS), firmness and shelf life. Results indicated that greenhouse and field grown fruits from the control and plants supplied with 100 kg NPK ha-1 had low PWL at both storage temperatures. Field grown fruits from the control stored at room temperature had the highest TSS and were firmer after 28 days of storage. Field grown fruits not supplied with fertilizer and stored at low temperature had a shelf life of 27 and 26 days in trial one and two respectively. Application of 100 kg NPK ha-1 and storage of pepino melon fruits at low temperature can be used to enhance quality and shelf life.

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.

Alstroemeria flowers have shown great importance in the world trade of cut flowers due mainly to its beauty and wide variety of colors. However, the durability of its inflorescences is usually hampered by the rapid yellowing of the leaves, which impairs their decorative quality. Cut flowers require the use of technologies to improve postharvest quality and floral longevity. This research aimed to study the postharvest conservation of inflorescences of Alstroemeria cv. Ajax at different storage temperatures. Floral stems were placed in containers with distilled water and stored at four temperatures (4, 8, 12, and 22ºC) for 12 days. The following analyses were performed: fresh mass variation, respiratory activity, relative water content, soluble and reducing carbohydrate contents, polyphenol-oxidase and peroxidase enzymes, pigments (anthocyanin and carotenoids), and longevity. The experiment was conducted in a completely randomized design, the results were submitted to analysis of variance (ANOVA), and the effect of treatments submitted to F-test. Significant differences were compared using the least significant difference (LSD) at 95% confidence interval (p ≤ 0. 05). The temperatures of 8 and 12ºC were effective in maintaining the postharvest quality of inflorescences during storage period, as they remained turgid due to transpiration reduction caused by low temperatures, and longevity reaching 46 and 22 days, respectively.
