Influence of Heat Treatments on Carotenoid Content of Cherry Tomatoes
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...
متن کاملAntioxidative activity and carotenoid and tomatine contents in different typologies of fresh consumption tomatoes.
The phytonutrient intake associated with tomato consumption depends also on cultivar and fruit ripening stage. This work associates the antioxidative ability, the level of carotenoids, and the amount of glycoalkaloids to the main carpometric characteristics of four different typologies of tomatoes: "cherry", "cluster", "elongated," and "salad". These typologies have different weights and shapes...
متن کاملEnhancement of carotenoid biosynthesis in transplastomic tomatoes by induced lycopene-to-provitamin A conversion.
Carotenoids are essential pigments of the photosynthetic apparatus and an indispensable component of the human diet. In addition to being potent antioxidants, they also provide the vitamin A precursor beta-carotene. In tomato (Solanum lycopersicum) fruits, carotenoids accumulate in specialized plastids, the chromoplasts. How the carotenoid biosynthetic pathway is regulated and what limits total...
متن کاملCarotenoid absorption in humans consuming tomato sauces obtained from tangerine or high-beta-carotene varieties of tomatoes.
Tomato sauces were produced from unique tomato varieties to study carotenoid absorption in humans. Tangerine tomatoes, high in cis-lycopene, especially prolycopene (7Z,9Z,7'Z,9'Z), and high-beta-carotene tomatoes as an alternative dietary source of beta-carotene were grown and processed. Sauces were served after 2 week washout periods and overnight fasting for breakfast to healthy subjects (n =...
متن کاملInheritance of Carotenoid Differences I N the Tomato Hybrid Yellow
ELLOW varieties of tomatoes have been known since the crop was first Y in t roduced into Europe shortly after the discovery of America, and were probably to be found in Mexico before the conquest (JENKINS 1949). HALSTED et al. (1905) reported on the red x yellow hybrid, establishing the fact that the color difference was due to segregation at a single locus, a conclusion that has been confirmed...
