Seaweeds are rich sources of bioactive natural products, which have been considered as potential biotic agents. Ulva flexuosa Wulfen is a species of seaweed which is endemic to the Persian Gulf. In this study, the effect of different concentrations of U. flexuosa extract on  the  antioxidant activity of Washington Navel orange (Citrus sinensis L. cv. Washington Navel)...

Pitaya (Hylocereus undatus) is a non-climacteric fruit that reaches its best eating quality when harvested ripe, decreasing thereafter during storage (CHIEN et al., 2007). As a new crop, there have been limited studies focused on extending the postharvest quality of pitaya fruit. The main postharvest problems of pitaya fruit are mechanical injury, chilling injury, decay, and water loss (NERD et...

In the present study, effects of edible coatings using sodium alginate (SA) and sodium alginate in combination with ascorbic acid (AA) on the shelf-life extension of strawberries at 4±1°C was studied. A factorial experiment was performed based on a randomized complete block design with four replications. The treatments included control (distilled water), SA (1%, 2%, 3% w/v), SA in combination w...

Polyphenol oxidase (PPO) plays a key role in the postharvest pericarp browning of litchi fruit, but its underlying mechanism remains unclear. In this study, we cloned the litchi PPO gene (LcPPO, JF926153), and described its expression patterns. The LcPPO cDNA sequence was 2120 bps in length with an open reading frame (ORF) of 1800 bps. The ORF encoded a polypeptide with 599 amino acid residues,...

A novel edible coating based on Aloe vera gel obtained according to SP Patent Filed 200302937 has been used as a means of preservation to maintain the quality and safety of cv. Crimson Seedless table grapes during cold storage and subsequent shelf life. Table grapes have a crucial economic value as a dessert fruit, but once harvested show a reduction of shelf life due to a rapid loss of quality...

'Guiwei' litchi fruit were treated with 5 ga.i. L(-1) apple polyphenols (APP) and then stored at 25°C to investigate the effects on pericarp browning. APP treatment effectively reduced pericarp browning and retarded the loss of red colour. APP-treated fruit exhibited higher levels of anthocyanins and cyanidin-3-rutinoside, which correlated with suppressed anthocyanase activity. APP treatment al...

The fresh produce industry is constantly growing, due to increasing consumer demand. The shelf-life of some fruit, however, is relatively short, limited by microbial contamination or visual, textural and nutritional quality loss. Thus, techniques for reducing undesired microbial contamination, spoilage and decay, as well as maintaining product’s visual, textural and nutritional quality are in h...

Rambutan ( Nephelium lappaceum L.) (Sapinadeae) fruit, a nutritional staple in Hawaii, exhibits desiccation and physiological browning soon after harvest, methods to prolong shelf life may be commercially advantageous. In this study, freshly harvested fruit were treated with pectin coatings or without trans-cinnamaldehyde (TCIN) stored at 10 °C 20 (room temperature) evaluate postharvest quality...

1-Methylcyclopropene (1-MCP), an inhibitor of ethylene perception, has been commercialized as SmartFresh technology for postharvest use on fruits and vegetables around the world. 1-MCP is used widely on apple fruit in North America; its successful commercial uptake has occurred because the technology helps to maintain quality of the fruit, not only during storage, but also through the entire ma...
