BACKGROUND Recent outbreaks of vegetable-associated gastroenteritis suggest that enteric pathogens colonize, multiply and persist in plants for extended periods of time, eventually infecting people. Genetic and physiological pathways, by which enterics colonize plants, are still poorly understood. METHODOLOGY/PRINCIPAL FINDINGS To better understand interactions between Salmonella enterica sv....
sensitivity of tomato fruits to chilling injury limits its storage and marketability. this study investigated the effect of hot water treatment (hwt) on reducing the consequences of chilling injury (ci) with respect to quality attributes of tomatoes during storage. tomatoes were harvested at three ripening stages: mature green, pink, and red; dipped in hot water at 45°c for 15 min; and stored a...
A novel in-package ozonation device was evaluated for its efficacy in inactivating three microorganisms (viz., Listeria innocua, attenuated Salmonella Typhimurium, and Escherichia coli O157:H7) on tomatoes and for its effect on fruit quality. The device produced ozone inside sealed film bags, reaching a concentration of 1,000 ppm within 1 min of activation. The three bacterial cultures were in...
flavor associated with high soluble solids and soluble solids/titrateable acidity ratios. High sugar and high acid contents generally have a favorable effect on taste. Differences between the flavors of varieties and the weaker flavor of greenhouse-grown or artificially ripened tomatoes are explained by the different quantitative proportions of the volatile substances. Of the environmental fact...
INTRODUCTION Tomato is considered a healthy food due to its high content in lycopene and other health-promoting natural compounds. Tomatoes have, undoubtedly, assumed the status of a food with functional properties, considering the epidemiological evidence of reducing the risk of certain types of cancers. OBJECTIVE Samples of tomatoes from Morocco were analyzed for the mineral composition. ...
Current strategies for management of Pratylenchus penetrans in both white potato and tomato consist of the use of fumigant or non-fumigant nematicides or crop rotation. The objective of this study was to determine if double-cropping African marigolds (Tagetes erecta) with potatoes or tomatoes could reduce P. penetrans populations. Plots were 10 m x 3 m arranged in a randomized complete block de...
Salmonella internalization in tomatoes during postharvest handling is a major food safety concern. This study was conducted to determine the effect of immersion time, immersion depth, and temperature differential between bacterial suspension and tomato pulp on the internalization of Salmonella enterica in tomato fruits. The effect of storage temperature and duration on the survival and growth o...
For the past 20 years, the National Foundation for Agricultural Research in Crete and the School of Agricultural Technology of the Technological and Educational Institute of Crete have been involved in a number of research and development activities, related to the production and evaluation of compost derived from a variety of local solid, mainly agricultural organic wastes. Materials such as o...
