The past twenty years has seen the field of postharvest biocontrol evolve into a sophisticated science with global research programs worldwide, numerous yearly publications, patented technologies, and the development of new commercial products. The use of these products, however, still remains limited. The practical application of postharvest biocontrol has changed from a very classical view of...

Preand postharvest contamination of aflatoxin in maize is a major health deterrent for people in Africa where maize production has increased dramatically. This chapter highlights management options for preand postharvest toxin contamination in maize. Sound crop management practices are an effective way of avoiding, or at least diminishing, infection by Aspergillus jlavus and subsequent aflatoxi...

Ultralow oxygen (ULO) treatments with different oxygen levels, treatment times, and temperatures were studied to determine effects on western ower thrips mortality and postharvest quality of iceberg lettuce. Thrips mortality increased with reduced oxygen level and increased treatment ime and temperature. At 0.003% oxygen, over 99.6% mortality rates of thrips were achieved in three ULO treatment...

We examined the effectiveness of intermittent warming (IW), hot water (HW), salicylic acid (SA), and calcium chloride (CaCl2) on the postharvest life of pomegranate fruit cv. ‘Shishe-Kab’ and extending fruit shelf life during cold storage (3°C). Fruit were subjected to cycles of 1 d at 17 ± 1°C every 6 d of storage at 3°C under IW conditions. Pre-storage treatments were HW (50°C) for 3 min, SA ...

Nitric oxide (NO) is a newly discovered fumigant for postharvest pest control. This paper provides detailed protocols for conducting NO fumigation on fresh products and procedures for residue analysis and product quality evaluation. An airtight fumigation chamber containing fresh fruit and vegetables is first flushed with nitrogen (N2) to establish an ultralow oxygen (ULO) environment followed ...

Pitaya is one of the most important commercial cactus fruit. Pitaya fruits are easy to get injury during postharvest handling and storage. Pre-harvest and postharvest calcium treatments have been used to maintain flesh firmness and extend shelf life of many fruits. The aim of this study was to evaluate the effects of calcium treatments on maintaining pitaya fruit quality during cold storage. Pi...

Since the surfaces of cantaloupes are highly rough or irregular, bacteria can easily attach and become difficult to remove. Appropriate postharvest washing and sanitizing procedures can help control Salmonella and other pathogens on cantaloupe or other melons during postharvest operations. Delmopinol hydrochloride (delmopinol) is a cationic surfactant that is effective for treating and preventi...

the main postharvest problems of persimmon in iran are severe softening and disease incidence on the fruits during storage. therefore, delay in softening and/or control of diseases result in the storage life extension of persimmon fruit. the strategy of induced disease resistance in plants by biotic and abiotic treatments is an attractive method for controlling diseases. salicylic acid (sa) is ...

The antioxidant capacity, total anthocyanins, total phenolics, volatile compounds, and postharvest quality of strawberry fruit were evaluated after treatment with natural antimicrobial compounds and during storage at 7.5 ◦C. Strawberries treated with methyl jasmonate (MJ) in conjunction with ethanol (MJ-ETOH) showed higher antioxidant capacity, total phenolics, and anthocyanins than those treat...

Development of disorders during postharvest ripening and storage of fruit depends on a range of preharvest factors. The most obvious of these is maturity of fruit at harvest. However, a number of other factors may be just as important in ripening-related disorders and in determining how fruit respond to low temperatures or other imposed postharvest conditions. Fruiting position on the tree and ...
