Variability in the content of soluble sugars and cell wall polysaccharides in red‐ripe cherry and high‐pigment tomato cultivars

Abstract

BACKGROUND: Soluble sugars and cell wall polysaccharides are well known for contributing to a range of 'quality' characteristics of fresh vegetables such as flavour, texture and healthy properties. Red-ripe berries of 14 cultivars of cherry tomatoes and four cultivars of high-pigment tomato hybrids, cultivated in the south of Italy, were analysed for their content of these important qualitative parameters.

Morphology, profile and role of chelate-soluble pectin on tomato properties during ripening

“…Compared with the standard monosaccharides (Fig. 1a), there was no fucose (Fuc) detected from the tomato CSP, which was consistent with previous reports (Kirby et al, 2008;Lenucci et al, 2008). Both the Lenucci and Kirby groups reported that only trace of fucose existed in the whole cell walls of tomatoes.…”

“…is a climacteric fruit in which ripening is accompanied by softening and physicochemical changes. The pectin changes during tomato ripening which might be associated with the texture of fruits, one important quality factor of the fruit shelf-life and commercial value (Almeida & Huber, 2008;Lenucci, Leucci, Piro, & Dalessandro, 2008;Zhang et al, 2008). So far, much of the work in the area of tomato ripening has been focused on extending tomato consistency, colour and shelf-life (Martínez-Romero et al, 2009).…”

Hemicellulose fine structure is affected differently during ripening of tomato lines with contrasted texture

“…The results confirm previous observations on tomato cell wall composition and its variation with ripening and genetic background [65][66][67][68][69][70][71][72][73][74][75][76][77][78]. These are known to mainly affect pectin molecular weight, methyl esterification of HG domains and galactan and arabinan side chains of RGI domains.…”

Influence of high lycopene varieties and organic farming on the production and quality of processing tomato

“…In previous studies 'Kalvert' 392 already showed high levels of sugar accumulation. Lenucci et al (2008) reported mean values 393 of fructose plus glucose of 23 g kg -1…”
