In recent years, multiple outbreaks of Salmonella infection have been associated with fresh tomatoes. Investigations have indicated that tomato contamination likely occurred early in the farm-to-consumer chain, although tomato consumption occurred mostly in restaurants. Researchers have hypothesized that tomato handling practices in restaurants may contribute to these outbreaks. However, few em...
Tomatoes and tomato products are rich sources of carotenoids-principally lycopene, followed by β-carotene and lutein. The aim of this work was to study the effect of heat treatment on carotenoid content in cherry tomatoes. Raw and canned products were sampled and analysed; furthermore whole, skin and pulp fractions of cherry tomatoes were analysed when raw and home-processed, in order to better...
The quality of fruit targeted for human consumption is affected greatly by the methods used in processing. The objective of this study was to assess a method of treating cantaloupe melons to reduce the wound responses incurred by cutting while maintaining fruit quality. After being treated with an alternating magnetic field (AMF) at the strength of 2mT for 0, 5, 10, 15, 20, or 25 min, Cucumis m...
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...
Presence of phytochrome in two kinds of tomatoes (Lycopersicon esculentum Mill.), the yellow lutescent strain and cherry tomatoes (L. esculentum Mill. var. cerasiformecv. Red Cherry), was established by measuring the absorption difference spectra of the whole fruit after irradiation with red and with far red light. Phytochrome content was determined in yellow lutescent tomatoes and decreased gr...
BACKGROUND During harvest and transportation, processing tomatoes are exposed to elevated temperatures, compression and vibration in the harvester and truck, making them prone to bruising. The objective of this study was to determine how bruising and exposure to high temperatures affect pectin methylesterase (PME) activation and the textural quality of tomato juice. RESULTS Tomatoes were both...
