Postharvest handling and cooling of fresh fruits, vegetables, and flowers for small farms: Quality Maintenance

Fresh fruits, vegetables and flowers must be in excellent condition and have excellent quality if maximum shelf life is desired. The best possible quality of any commodity exists at the moment of harvest. From that point on, quality cannot be improved, only maintained. Remember that shelf life...

Postharvest handling and cooling of fresh fruits, vegetables, and flowers for small farms: Cooling

Field heat should be removed from fresh fruits, vegetables, and flowers as quickly as possible after harvest. Each commodity should be maintained at its lowest safe temperature. Cooling and storage requirements for specific commodities are presented below, in NC Cooperative Extension Service...

Postharvest handling and cooling of fresh fruits, vegetables, and flowers for small farms: Handling

The most important key to quality maintenance of fresh fruits, vegetables, and flowers is careful handling – Tender Loving Care! Symptoms of injuries incurred during harvesting, handling, grading, and packaging usually are not evident until the products reach retail or consumer levels...

Towards Controlled Atmosphere Storage for Honeycrisp Apples

Although Honeycrisp can store well in air, it is generally recognized that loss of acidity can result in decreasing fruit quality over time. Therefore, there has been interest in developing controlled atmosphere (CA) storage regimes to maintain fruit quality for extended periods during storage....

Physical and chemical quality changes of longkong (Aglaia dookkoo Griff.) during passive modified atmospheric storage

Longkong is a tropical and non-climacteric fruit which is highly perishable after harvest. The shelf life extension of longkong by using passive MAP with two different OTR packages and stored at 18ºC, 25ºC and at a 85% of relative humidity was investigated. In this study, physical and...

Evaluation of Current Operating Standards for Chlorine Dioxide in Disinfection of Dump Tank and Flume for Fresh Tomatoes

  Standard postharvest unit operations that rely on copious water contact, such as fruit unloading and washing, approach the criteria for a true critical control point in fresh tomato production. Performance data for approved sanitizers that reflect commercial systems are needed to set...

Variable agronomic practices, cultivar, strain source and initial contamination dose differentially affect survival of Escherichia coli on spinach

  Aims: Greenhouse and field trials were conducted under different agronomic practices and inoculum doses of environmental Escherichia coli and attenuated E. coli O157:H7, to comparatively determine whether these factors influence their survival on leaves and within the rhizosphere. Methods...
