Post Harvest Treatment Effects on Crown-Cut Broccoli Shelf Life
The effects of packaging treatments, post harvest cooling delay and storage duration on color, texture, ascorbic acid content, weight loss and glucosinolate retention in crown-cut heads of broccoli were studied. Oxygen and CO2 levels inside shrink wrap packages were also monitored. Shrink wrap …

Effect of post-harvest treatment on ripening and quality of tomato fruit using ozone. Application of different ozone doses as controlled atmosphere storage for delay ripening and maintaining the quality of tomatoes and effect of ozone on antioxidant and sugar compounds at different stages of tomato fruit ripening.
… is to prevent the high loss incurred during harvest, handling and transportation of the crops. The objective of this study was to investigate the overall nutritional implication of controlled storage of tomatoes using ozone on the ripening process and the basic nutritional components of …

Phomopsis castanea infection levels in chestnut from the North and South Islands of New Zealand
… the spread of the disease from nut to nut after harvest and during storage was not significant. The conclusion of this study is that the control of Phomopsis rot will be achieved by a range of measures such as, choice of well adapted cultivars associated with good pollinators, good orchard …

Post-harvest spray treatments to reduce Salmonella contamination on cantaloupe surfaces
… CPC to cantaloupe surfaces may be an alternative post harvest technique to reduce the frequency and level of Salmonella contamination. Cantaloupe (Athena and Hale's Best Jumbo (HBJ) cultivars) rind plugs were inoculated with a broth culture of Salmonella Michigan. After 15 min, plugs were sprayed …

Allyl isothiocyanate reduces Salmonella enterica Michigan and Listeria monocytogenes on the surface of whole cantaloupe (Cucumis melo L.)
… outbreaks linked to whole cantaloupe fruit. No post-harvest intervention to reduce potential contamination on cantaloupe currently exists. The complex surface topography of netted cantaloupes aids bacterial attachment. This research evaluates the use of allyl isothiocyanate (AITC; a natural …

Effect of Standard Post-harvest Interventions of Fresh Vegetables on Bacterial Community Dynamics, Pathogen Survival and Antibiotic Resistance
… before consumption. Raw manure or improperly composted manure applied as soil amendments is an established source of pathogenic bacterial contamination. However, less is known about whether such soil amendments could serve as a source of transmission of antibiotic-resistant bacteria (ARB) or …

Preparation and application of new sorptive polymers applied to wine with a focus on removal of 3-isobutyl-2-methoxypyrazine
… materials have been investigated as a remedial treatment to remove undesirable compounds from wines. In order to decrease the loss of desirable components and improve selectivity, tailor-made sorbents known as molecularly imprinted polymers (MIPs) have also been produced and broadly studied. …
