Article
Blueberries have increased in popularity in recent years due to their nutritional benefits and sensory characteristics. However, to preserve quality and extend shelf-life, they need to be maintained at refrigerated temperatures and high relative humidity, conditions that are not routinely met along the supply chain. Poor temperature management lead...

Strawberries are greatly appreciated for their flavor and health-promoting properties. However, current agricultural and postharvest handling practices may result in decreased fruit quality. The objective of this work was to determine the effect of conventional or reduced fungicide applications on the quality of ‘Florida Radiance’ strawberries expo...
Article
Many studies stress the importance of keeping strawberries at high relative humidity conditions during postharvest storage. However, the effect of deviations occurring across the supply chain on the appearance, acceptability and biochemical properties of strawberries has not been adequately explored or quantified to date using kinetic modelling app...
Article
Strawberries are among the most frequently wasted fruits because of their high perishability and handling requirements. Loss of quality begins at the farm and accumulates throughout the supply chain. There is a lack of information regarding the level of impact of each step along the supply chain on strawberry quality, and on how to prioritize actio...

As a soil amendment, biochar can significantly improve soil quality and crop growth. Few studies, however, have explored biochar effects on crop quality. This study investigated the amendment effects of bamboo biochar pyrolyzed at different temperatures on plant growth and fruit quality of tomato (Solanum lycopersicum L.). Tomato ‘Micro-Tom’ plants...
Article
Using alternative agricultural practices in combination with proper postharvest handling has become a major goal to improve fresh produce quality. Here, two different strawberry (Fragaria × ananassa) genotypes were used as a model to study the impact of repeated, reduced-fungicide or no-fungicide applications on the sensory quality, physicochemical...
Article
Polyphenols of plant origin have received special interest in the last decade because of their potential health benefits. Consequently, many beverages with words ‘antioxidant’ and ‘polyphenols’ have been developed. However, many of the claims are misleading because some beverages so labelled have either no or minimal levels of polyphenols. The obje...

‘Valencia’ orange trees from groves with 90% infection by Candidatus liberibacter asiaticus ( C Las), the presumed pathogen for citrus greening or huanglongbing (HLB) disease, were treated with insecticide ( I) , a nutritional spray ( N ), and insecticide plus nutritional spray ( I + N ). Controls ( C ) were not treated. Fruit were harvested in Mar...
Article
Full-text available
A 3-year study was undertaken to establish the effect of field nutritional sprays, combined with insecticide treatments or not against Asian Citrus psyllid, on the fruit quality of ‘Valencia’ orange trees affected by the greening disease Huanglongbing (HLB). Four replicated plots were harvested, juiced, and pasteurized. Nine to twelve trained panel...
Article
Strawberry breeding programs are constantly engaged in the development of new cultivars with increased performance and improved quality traits. The recent release of Sensation® ‘Florida127’ aims to accomplish these goals, yet its postharvest performance has not been rigorously studied. Therefore, the main objective of this study was to compare the...
Article
Strawberries are one of the most important food crops grown in Florida, with a harvested area of ≈10,000 acres. The University of Florida strawberry breeding program develops cultivars adapted to this region and its particular weather conditions, with a major aim of increasing overall quality. The objective of this study was to compare the fruit of...
Article
Full-text available
Growing environmental awareness in combination with concerns about safer produce has led people to question modern agricultural practices. This is reflected in an increasing demand for organic produce which is perceived as less damaging to the environment and to be healthier than that which is conventionally grown. During the Florida and California...
Article
Full-text available
Shelf life of fresh fruits and vegetables is greatly influenced by environmental conditions. Increasing temperature usually results in accelerated loss of quality and shelf-life reduction, which is not physically visible until too late in the supply chain to adjust logistics to match shelf life. A blackberry study showed that temperatures inside pa...
Article
‘Goldfinger’ bananas (Musa accuminata, FHIA-01) were harvested, held for 14-22 d at five temperatures and a constant relative humidity (RH) or at five RHs and a constant temperature and evaluated for quality attributes. The objectives of this work were to: (1) create quality curves for bananas stored at chilling and non-chilling temperatures; (2) c...
Conference Paper
The citrus disease, Huanglongbing (HLB) has been demonstrated to impart off-flavor to orange fruit and juice. This is more prevalent in fruit that are symptomatic for the disease (small, green and lopsided). Growers in Florida are resorting to foliar nutritional spray programs for management of HLB disease, in lieu of removing symptomatic trees, to...

The optimal ripeness stage for processing and marketing fresh-cut mangoes (Mangifera indica 'Kent') with best quality and maximum shelf life was determined. The initial ripeness stage selection was based on whole fruit firmness because this quality attribute was more reliable in predicting fresh-cut shelf life than flesh color or soluble solids con...

Despite widely advertised health benefits, most Americans do not eat their recommended daily servings of fruits and vegetables. We believe that inconsistent produce quality, particularly flavor, is a key factor contributing to this low consumption. Poor tasting produce is often associated with varieties that lack good flavor potential, immature pro...

Asparagus (cv. Locullus) was stored at 20C for 20 h to simulate time delays and temperature typically encountered during air-shipment operations. After that period, asparagus were immediately forced-air cooled at 1C, or room cooled at 1C or 10C, or stored at 20C to simulate different facility conditions usually available at the airports. The object...

Harvested commodities lose moisture by transpiration, with the rate of loss affected by environmental factors such as temperature (T), relative humidity (RH), and atmospheric pressure (P). Commodities are commonly exposed to high T, low P, and large vapor pressure deficit (VPD) during air shipment, which can increase the transpiration rate and resu...
