The homogeneity of analytical samples and the stability of pesticides during the sample processing of oranges and tomatoes were evaluated. The mean concentrations of 14C-labeled chlorpyrifos in analytical portions (subsamples) after processing show that homogeneity is dependent on sample type as well as the processing procedure. The homogeneity of analytical samples of tomatoes processed cryoge...

Rotten Spouses, Family Transfers and Public Goods We show that once interfamily exchanges are considered, Becker’s rotten kids mechanism has some remarkable implications that have gone hitherto unnoticed. Specifically, we establish that Cornes and Silva’s (1999) result of efficiency in the contribution game amongst siblings extends to a setting where the contributors (spouses) belong to differe...

Food processing by-products are commonly used as feed ingredients for livestock. Wet tomato pulp is byproduct containing tomato seeds and skin residues and obtained during processing of tomatoes for paste, juice, ketchup etc. Tomato production in Turkey was around 10 million tons and approximately 3 million tons tomatoes were used for processing of tomatoes in 2010 [48]. During production of to...

Shelf life is one of the most important traits for the tomato (Solanum lycopersicum) industry. Two key factors, post-harvest over-ripening and susceptibility to post-harvest pathogen infection, determine tomato shelf life. Anthocyanins accumulate in the skin of Aft/Aft atv/atv tomatoes, the result of introgressing alleles affecting anthocyanin biosynthesis in fruit from two wild relatives of to...

The effect of organic and conventional agricultural systems on the physicochemical parameters, bioactive compounds content, and sensorial attributes of tomatoes ("Redondo" cultivar) was studied. The influence on phytochemicals distribution among peel, pulp and seeds was also accessed. Organic tomatoes were richer in lycopene (+20%), vitamin C (+30%), total phenolics (+24%) and flavonoids (+21%)...

A multi-spectral fluorescence imaging technique was used to detect defective cherry tomatoes. The fluorescence excitation and emission matrix was used to measure for defects, sound surface and stem areas to determine the optimal fluorescence excitation and emission wavelengths for discrimination. Two-way ANOVA revealed the optimal excitation wavelength for detecting defect areas was 410 nm. Pri...

With the aim of estimating the growth of tomatoes during the agricultural season, we propose to segment tomatoes in images acquired in open field, and to derive their size from the segmentation results obtained in pairs of images acquired each day. To cope with difficult conditions such as occlusion, poor contrast and movement of tomatoes and leaves, we propose to base the segmentation of an im...

T o m a t o products, including ketchup, tomato juice, and pizza sauce, are the richest sources of lycopene in the U.S. diet, accounting for greater than 80 percent of the total lycopene intake of Americans. In addition to tomatoes (Lycopersicon esculentum) and tomato-based products, lycopene is also found in watermelon, papaya, pink grapefruit, and pink guava. Lycopene from both processed and ...

Five different serotypes of Salmonella enterica were implicated in a large outbreak linked to fresh Roma tomatoes served at gas station deli counters in Pennsylvania and nearby states during July 2004: S. enterica serotypes Javiana, Anatum, Thompson, Typhimurium, and Muenchen. One of these serotypes, Anatum, was isolated from both tomatoes and patients. Pulsed-field gel electrophoresis (PFGE) p...

Recently, it started gaining more medicinal value because of the antioxidant property because of ascorbic acid and lycopene content (Anon., 2000). Hence tomatoes are called as poor man’s apple (Rick, 1969). Tomatoes offer significant nutritional advantages, including providing a significant source of dietary lycopene, β-carotene, carotenoids, vitamin C, potassium, fiber, color, flavor and antio...
