This work was carried out during two successive seasons (2009) and (2010) to examine the response of Florida Prince peach fruits to some pre-harvest treatments i.e. chitosan at 0.5 and 1.0% and CaCl2 at 2 and 4 % as well as their combinations on some fruit quality parameters under cold storage . Fruit weight loss (%), decay (%) and T.S.S.(%) of Florida Prince peach fruits were increased in most...

Calcium is thought to be the most important mineral element determining fruit quality. It seems to be especially important in apples where it has been shown to reduce metabolic disorders. Calcium in adequate amounts helps to maintain apple fruit firmness and decreases the incidence of physiological disorders such as water core, bitter pit and internal breakdown. Postharvest decay may also be re...

3. DECAY PREDICTION. Unfortunately, decay prediction models for stone fruit have not been developed yet. A possible method of disease prediction might consist of prior to commercial harvest placing fruit of more advanced maturity into a plastic bag with wet paper to induce decay development. If decay develops rapidly, this may suggest that some lots of fruit receive additional preharvest fungic...

The marketing of organic citrus fruit has markedly increased during the last few years. However, these fruits are not treated with chemical fungicides and suffer from relatively high rates of decay. In this study, we examined the possible use of a new hot water brushing (HWB) treatment, to disinfect the fruits and reduce decay development during postharvest storage. Preliminary observations hav...

Changes in fruit quality, decay, phenolic and anthocyanin content, and antioxidant capacity of strawberries (Fragaria ananassa Duch. cv. Allstar) stored under air and high oxygen atmospheres at 5 1C were investigated. Freshly harvested strawberries were placed in jars and ventilated continuously with air or with 40, 60, 80, or 100 kPa O2 at 5 1C for up to 14 days. Samples were taken initially, ...

In recent years, safer methods for the control of fruit postharvest pathogens have been investigated and heat treatment could represent an effective and safe approach for managing postharvest decay such as Monilinia rots. In the present study, the effect of hot water treatment (HWT) (60◦C for 30 and 60 s) on brown rot was investigated. More specifically, the influence of HWT was determined in i...

Strawberries (Fragaria×ananassa Duch.) were coated with either 1% or 1.5% chitosan (CS) or chitosan combined with calcium gluconate (CaGlu). Following treatment, strawberries were stored at 10°C and 70±5% RH for one week. The effectiveness of the treatments in extending fruit shelf-life was evaluated by determining fungal decay, respiration rate, quality attributes and overall visual appearance...

The effects of methyl jasmonate (MeJA) on postharvest decay and antioxidant capacity in harvested Chinese bayberry fruit were investigated. Chinese bayberries were treated with 0, 1, 10, 100, or 1000 micromol L(-1) MeJA at 20 degrees C for 6 h and then stored at 0 degrees C for 12 days. MeJA at 10 micromol L(-1) was most effective in reducing fruit decay; quality parameters including pH value, ...

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...
