Calmodulin, a ubiquitous calcium sensor, plays an important role in decoding stress-triggered intracellular calcium changes and regulates the functions of numerous target proteins involved in various plant physiological responses. To determine the functions of calmodulin in fleshy fruit, expression studies were performed on a family of six calmodulin genes (SlCaMs) in mature-green stage tomato ...

Table grapes (Vitis vinifera cv. Cardinal) are highly perishable and their quality deteriorates during postharvest storage at low temperature mainly because of sensitivity to fungal decay and senescence of rachis. The application of a 3-day CO2 treatment (20 kPa CO2 + 20 kPa O2 + 60 kPa N2) at 0°C reduced total decay and retained fruit quality in early and late-harvested table grapes during pos...

Individual sealing and tray wrap of orange (Citrus sinensis (L.) Osbeck cv. ‘Valencia’) with heat-shrinkable films of low-density polyethylene (LDPE), high-density polyethylene (HDPE), oriented polypropylene (OPP) and polyvinyl chloride (PVC) were held for a period up to 4 months at 5°C and 85-90% RH. Both methods of film-packaging showed little change in the water relations characteristics, wh...

This study was carried out on the effectiveness of calcium chloride (CaCl2) treatments on the post harvest quality of peach fruits during cold storage at 10oC and 75 ± 5% RH. Different solutions of CaCl2 such as 1% (T1), 2% (T2) and 3% (T3) were prepared and the fruits were dipped for five minutes, while (To) was left with out calcium chloride treatment as control. The fruits were packed in cor...

This concept paper summarizes key “hotspots” for waste generation along the food supply chain and identifies a range of existing solutions/measures that can help producers, retailers and consumers reduce the amount of food that is wasted. The majority of food waste of 71–92 kg/head/year in Western Europe was found to originate from private households (61%), followed by restaurants and canteens ...

mechanical damagesin theprocessof harvestingandpost-harvest are the most important reason in cucurbits losses. it causes the tissue destructionand consequentfruits decay. because of difference in the mechanical strength of flesh and skin of cantaloupe, internal bruising are more usual damages with no visibility. this type of injuriesis hard to predict byanalytical methods. in this study,the mec...

In natural-light labeling of fruits and vegetables, the desired information is etched onto the produce surface using a low-energy carbon dioxide laser beam (10,600 nm). Etched characters are formed by surface depressions in the epidermis that may facilitate entrance of decay and pathogenic organisms. The objective of this study was to determine the effects of natural-light labeling and differen...

The physiological breakdown of citrus fruits variously known as storage spot, pitting, or pox has presented a perplexing problem to growers and shippers ever since the storage and transportation of these fruits was undertaken on an extensive scale. This breakdown manifests itself in various forms of blemishes of the rind, depending on such factors as the inherent condition of the fruit, the tem...
