Cherry tomato (Lycopersicon esculentum Mill) fruits are susceptible to contamination by Aspergillus flavus, which may cause the development of fruit rot and significant postharvest losses. Currently there are significant drawbacks for the use of synthetic fungicides to control pathogenic fungi in tomato fruits, and it has increased the interest in exploring new alternatives to control the occur...

Broccoli (Brassica oleracea var. italica) is a vegetable that requires the application of postharvest techniques to extend its marketability. Controlled atmosphere and 1-MCP treatments are most used to extend the shelf life of broccoli and reduce post-harvest deterioration. The aim of this study was to evaluate the visual, physicochemical and functional changes of broccoli head samples stored a...

because of the harmful effects of chemicals on human health and environment, use of these compounds in postharvest technology of agricultural crops is recently restricted and it is necessary to find safe compounds for use in postharvest technology of fruits and vegetables. in this study, effects of salicylic acid and aloe vera gel on quality attributes and postharvest life of table grape(cv. gi...

Starch is one of the most important storage carbohydrates in plants. Kiwifruit typically accumulate large amounts of starch during development. The fruit retain starch until commercial maturity, and its postharvest degradation is essential for consumer acceptance. The activity of genes related to starch degradation has, however, rarely been investigated. Based on the kiwifruit genome sequence a...

Changes in aerobic plate count (APC) and Escherichia coli/coliform count (ECC) of inshell walnuts and walnut kernels were evaluated during commercial harvest and postharvest handling. APC and ECC for inshell walnuts collected from the tree were 6 and 4 log CFU/nut, respectively; counts increased by 1 log during harvest and hulling and decreased by 1 log during drying. Application of up to 200 p...

The efficacy of Bacillus subtilis SM21 on controlling Rhizopus rot caused by Rhizopus stolonifer in postharvest peach fruit and the possible mechanisms were investigated. The results indicated B. subtilis SM21 treatment reduced lesion diameter and disease incidence by 37.2% and 26.7% on the 2nd day of inoculation compared with the control. The in vitro test showed significant inhibitory effect ...

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...

A. R. Collins explained that damage to DNA was the originating event in the process of carcinogenesis. “The damage can be caused by environmental or endogenous (produced within the body) processes, and oxidative damage caused by reactive oxygen molecules released during cellular respiration is thought to make a significant contribution.

The postharvest life of mango is limited by the development of pathogens, especially fungi that cause rot, among which stands out the Lasiodiplodia theobromae. Several control methods have been employed to minimize the damages caused by this fungus, chemical control can leave residues to man and nature; physical control by the use of gamma radiation in combination with modified atmosphere and c...
