Organically grown products experienced a doubling in percent penetration of organic sales into retail markets during the period from 1997 to 2003; however, there is still a debate over the perceived quality advantage of organically grown fruits and vegetables. In a study focusing on commercial production of processing tomatoes, samples were analyzed from 4 growers with matched organic and conve...

BACKGROUND The effects of industrial tomato paste processing and long-term (12 months) ambient storage on the content and stability of quercetin, kaempferol, ascorbic acid (AA), dehydroascorbic acid (DHAA), β-carotene and lycopene were evaluated in a commercially produced tomato paste. RESULTS The initial thermal treatment (hot break; 93 °C for 5 min) resulted in significant reductions in que...

in a 3×3 latin square design, 9 ok and multipaous lactating holstein cows averaging 76 ± 12 days in milk and 580±48 kg of body weight were assigned to three dietary treatments in 3 periods of 21 days. dietary treatments were 1) the control diet (without dried or ensiled tomato pulp), 2) diet with 8% dried tomato pulp (dm basis) and 3) diet with 8% ensiled tomato pulp silage (dm basis). tomato p...

Tomato is a versatile vegetable that is consumed fresh as well as in the form of processed products. More recently, there has been renewed attention given to the antioxidant content of tomatoes because many epidemiological studies suggested that regular consumption of fruits and vegetables, including tomatoes, can play an important role in preventing cancer and cardiovascular problems. Approxim...

Carotenoids are the main tomato components, especially lycopene. Lycopene is more bioavailable in tomato processed products than in raw tomatos, since formation of lycopene cis-isomers during food processing and storage may increase its biological activity. In the current study, we evaluated the influence of lycopene extracts (5 mg / mL) from different tomato-based food products (paste, sauce, ...

The aim of this research is to fortify cheddar cheese’s nutritional value by adding tomato paste. This study transformed ultra-heat treatment (UHT) milk into cheese through cheddaring. Tomato paste was added at 5 g/L, 10 and 15 g/L during the first curd formation, together with calcium chloride (CaCl 2 ). type rennet (animal microbial) varied 0.25 ml/L milk. Ripening done in one month 4°C. Acco...

The consumption of fruits and vegetables is accepted to be one of the strategies to reduce risk factors for these diseases. The aim of this study was to examine potential relationships between the antioxidant and the antiplatelet activities in green mature and fully ripe (red) tomatoes and of lycopene-rich byproducts of tomato paste processing such as pomace. The total phenol content of tomato ...

Tomato is a globally famous food and contains several phytonutrients including lycopene, β-carotene, anthocyanin, and flavonoids. The increased temperature used to produce tomato juice, ketchup, tomato paste and canned tomato enhances the bioactive composition. We aimed to verify the beneficial effects of processed tomato juice from Kagome Ltd. (KOT) on hypolipidemic action in hamsters with hyp...
