Consumption of tomato products has been associated with decreased risk of some cancer types, and the tomato antioxidant, lycopene, is thought to play an important role in the observed health effects. In this study, four carotenoids, trans-lycopene, phytofluene, phytoene, and zeta-carotene, were quantified in tomato products. Samples of raw tomatoes, tomato juice after hot break scalder, and fin...

tomato is one of the most important crops with a yeild of 98. 8 million tons in more than 128,000 hectare of area under cultivation and 3.7 million tons production in iran. with regard to technological advancement ( improvement, development ) and increasing demand of tomato and their products in iran and all over the world, it is necessary to know about affecting factors on production, process ...

Nuclear magnetic resonance (NMR) spectroscopy is used to track factory relevant tomato paste spoilage. It was found that spoilage in tomato paste test samples leads to longer spin lattice relaxation times T1 using a conventional low magnetic field NMR system. The increase in T1 value for contaminated samples over a five day room temperature exposure period prompted the work to be extended to th...

Although tomato paste research has received significant attention, relatively little effort has been addressed to optimization of value-added whole peel and diced tomato processing. Our laboratory has conducted research evaluating tomato attributes which may be indices of peelability and product yield. Eleven tomato varieties were harvested at USDA stage 4 (pink), USDA stage 6 (red) and red plu...

The effect of industrial processing was investigated on the stability of tomato carotenoids, phenolic compounds and ascorbic acid. A deep insight in the processed products allowed the quantification of caffeic acid hexosides, which are far more important contributors than the well-known chlorogenic acid, dicaffeoylquinic acids and quercetin oligosaccharides (new feruloyl, sinapoyl and syringoyl...

Background: Aflatoxin B1 is a secondary toxic metabolite produced by several aspergillus species. This study was conducted to determine the presence of aflatoxin in tomato paste samples. Methods: A total of 30 tomato pastes were analyzed for Aflatoxin B1 contamination via HPLC-FLD. Analyte extraction was done by dispersive liquid-liquid microextraction. Results: The limit of detection (LOD) and...

Background: using root beet powder pigments without extract or using organic solvents, to study the stability of pigments in model foods tomato paste, strawberry jam, juice, and burger, and to perform preliminary studies consumer acceptance of model foods containing them. Objective: The overall aim of this study was to use microencapsulation technique to increase the stability of red beet pigme...
