“…Chitosan-ascorbic acid coatings inhibited the browning of apple pieces, and browning inhibition was enhanced by increasing the ascorbic acid and chitosan ratio in the solution. These results were also supported by the studies on the beneficial side of chitosan on browning [41][42][43]. In addition, antibrowning agents such as ascorbic acid and citric acid suppress the polyphenol oxidase activity working as reducing agents [44].…”

Using natural antimicrobial substances in edible films becomes crucial to extend the shelf-life of fresh-cut fruits due to the consumers' preferences. In this study chitosan and ascorbic acid based film was used to improve the shelf-life of fresh-cut apples. Fresh-cut apple cubes were dipped in water (control), ascorbic acid (1%) or mixtures of chitosan-ascorbic acid in different ratios (1%:1%, 2%:2% or 1%:5%) for 5 min. After draining, fresh-cut apples were packed in sterile polypropylene jars and stored at 5 • C for 14 days. The treatment with chitosan and ascorbic acid suppressed browning, retained flesh firmness and maintained phenolic compounds throughout the storage period. Moreover, the treatment with chitosan-ascorbic acid significantly retarded the microbial growth during storage. Those findings suggested that the best performance was acquired in 1% chitosan and 5% ascorbic acid coating. That coating could be practical and useful to prolonging the chemical and microbial shelf lives of fresh-cut apples during refrigerated storage. Coatings 2019, 9, 503 2 of 12 packaging [8], chemical treatments [9], thermal treatments [10], edible coatings [11-13] and hurdle technologies [12,14]. Among these methods, edible coatings have been recently gained more interest than others in food preservation. Edible films and coatings are natural polymers which control moisture transfer, gas exchange, respiration and oxidative reaction rates during handling, storage and transportation of the fresh produce [15,16]. Carbohydrates, proteins, gums, lipids or starch-based edible films can be used as a coating material for fresh-cut products.Chitosan is a carbohydrate-based biopolymer. It is an amino polysaccharide composed of randomly distributed β-(1-4)-linked D-glucosamine and N-acetyl-d-glucosamine units [17][18][19]. Chitosan based edible films and coatings have great potential in the preservation of fruit and vegetables [20][21][22]. Chitosan and its derivatives have an ability to inhibit the growth of yeasts, molds and bacteria [23][24][25]. However, the application of chitosan is limited due to its insolubility at neutral pH [26]. To overcome this disadvantage and to improve solubility of chitosan, different acids were used to decrease pH values below pH 6 to improve chitosan solubility [16,21,[27][28][29]. Qi et al. 2011 [30] studied the effect of chitosan, ascorbic acid and calcium chloride on fresh-cut fuji apples. They used citric acid to dissolve chitosan and prepared film solutions by adding calcium chloride and ascorbic acid. They have found out that coatings effectively retarded enzymatic browning during storage at 5 • C for 8 days, and apple slices with chitosan-coating maintained firmness with a little loss during storage. In another study, calcium chloride-chitosan coatings and chitosan-ascorbic acid coatings during storage at room temperature for 10 h were investigated [31]. Calcium treatments (calcium chloride or lactate) are broadly studied in preserving the quality of fresh-cut fruit and vegatables. There ar...

“…El-Garhy et al [ 22 ] demonstrated that the pre-harvest spraying of bean plants with potassium thiosulfate decreased the pod rots caused by Botrytis cinerea and Sclerotinia sclerotiorum . Additionally, chitosan significantly decreased the microbial population on banana fruits during storage [ 61 ]. In the case of 15 days of cold storage, spraying tomato plants six times with chitosan was significantly more effective in reducing black mold infection in tomato fruits inoculated with A. alternata compared to three sprays.…”

The field application of safe chemical inducers plays a vital role in the stimulation of systematic acquired resistance (SAR) of plants. In this study, the efficacy use of three and six field applications with chitosan, lithovit, and K-thiosulfate at 4 g L−1 and salicylic acid at 1.5 g L−1 in improving tomato productivity, quality, and modifying the defense signaling pathways to the Alternaria alternata infection was investigated. Salicylic acid was the most effective in vitro where it completely inhibited the growth of Alternaria alternata. The highest yield quantity was recorded with six applications with Chitosan followed by Salicylic acid; also, they were the most effective treatments in controlling the Alternaria alternata infection in tomato fruits. The maximum increase in chitinase and catalase activity of tomato fruits was observed at five days after inoculation, following treatment with six sprays of salicylic acid followed by chitosan. The transcript levels of seven defense-related genes: ethylene-responsive transcription factor 3 (RAP), xyloglucan endotransglucosylase 2 (XET-2), catalytic hydrolase -2 (ACS-2), proteinase inhibitor II (PINII), phenylalanine ammonia-lyase 5 (PAL5), lipoxygenase D (LOXD), and pathogenesis-related protein 1 (PR1) were upregulated in response to all treatments. The highest expression levels of the seven studied genes were recorded in response to six foliar applications with chitosan. Chitosan followed by salicylic acid was the most effective among the tested elicitors in controlling the black mold rot in tomato fruits. In conclusion, pre-harvest chitosan and salicylic acid in vivo application with six sprays could be recommended as effective safe alternatives to fungicides against black mold disease in tomato fruits.

“…NF technology is very innovative and there are very few reports on their applications to fruit trees. Chitosan (C 6 H 11 O 4 N n ) is a polymer that is found in seafood wastes with many potentials for agricultural application such as increasing crop production and the quality of agricultural products . Chitosan NPs, when prepared by a nano spray dryer, and applied at 10 mg L −1 increased chlorophyll and photosynthesis rate, nutrient absorption, and seedling growth in coffee plants compared to the control .…”

Nanotechnology is currently being widely employed in agriculture and horticulture. The most widely investigated and developed factor related to fruit trees is nanofertilizers (NFs), which play very important roles in increasing vegetative growth, improving reproductive growth and flowering, thereby increasing productivity, product quality and ultimately increasing shelf-life and decreasing fruit waste. These nanomaterials, which are generally sprayed at low concentrations on trees at different time intervals and in frequent sessions, are also considered as growth stimulants. Macro-and micro-scale NFs such as zinc, boron, chitosan, and fertilizer nanocomposites such as ZnFeMnB (zinc, iron, manganese, boron), NPKMg (nitrogen, phosphorus, potassium, magnesium), and calcite have been shown to significantly improve the vegetative and reproductive traits of fruit trees such as pomegranate, strawberry, mango, date, coffee and grape. Knowledge on the effects of NFs on fruit trees and biological reasons for their effects on different traits is incomplete and there is an urgent need for extensive research on these topics.
