Regarding the distribution of vitamin A in the bodies of fish, there are two types of accumulation: one accumulates most of the vitamin A in the liver, and sometimes in the pyloric caeca also, but very little in the flesh; while the other type accumulates several times more vitamin in the flesh than in the liver. To the former type belong most species of commer cial fish, e. g. sharks, tuna, sk...

The health-promoting effects of phenolic compounds depend on their bioaccessibility from the food matrix and their consequent bioavailability. We carried out a randomized crossover pilot clinical trial to evaluate the matrix effect (raw flesh and juice) of 'Ataulfo' mango on the bioavailability of its phenolic compounds. Twelve healthy male subjects consumed a dose of mango flesh or juice. Bloo...

Phloem unloading plays a pivotal role in photoassimilate partitioning and the accumulation of sugars in sink organs, e.g. fruit. Here, we investigated the pathway of sucrose unloading in kiwifruit (Actinidia deliciasa cv. Qinmei) using a combination of electron microscopy, transport of the phloem-mobile symplastic tracer carboxyfluorescein and enzyme activity and gene expression assays. Our str...

Since the mid-1980s, concern has grown that invasive group A Streptococci (GAS) has been increasing in incidence and severity. Invasive infections caused by group A Streptococcus or Streptococcus pyogenes include sepsis, arthritis, pneumonia, meningitis, necrotizing fasciitis (NF) and streptococcal toxic shock syndrome (STSS). GAS also causes noninvasive suppurative disease as pharyngitis and o...

In this study Vitaton (an organic supplement which contains fermentative β-carotene) and synthetic astaxanthin (CAROPHYLL® Pink) were evaluated as pro-growth factors in Rainbow trout diet. An 8 week feeding trial was conducted to determine the effects of Vitaton versus astaxanthin on rearing factors, survival rate and visual flesh color of Rainbow trout (Oncorhnchynchus mykiss) with initial wei...

In terms of the quality of minimally processed fruit, flesh browning is fundamentally important in the development of an aesthetically unpleasant appearance, with consequent off-flavours. The development of browning depends on the enzymatic action of the polyphenol oxidase (PPO). In the 'Golden Delicious' apple genome ten PPO genes were initially identified and located on three main chromosomes...

The changes in endopolygalacturonase (endo-PG) levels and endo-PG expression in nonmelting flesh (NMF) and melting flesh (MF) peach fruits (Prunus persica) during softening were studied. The endo-PG gene was analysed to identify polymorphisms exploitable for early marker-assisted selection (MAS) of flesh texture. The role of endo-PG in softening was assessed by western and northern blotting and...

Peach flesh color (white or yellow) is among the most popular commercial criteria for peach classification, and has implications for consumer acceptance and fruit nutritional quality. Despite the increasing interest in improving cultivars of both flesh types, little is known about the genetic basis for the carotenoid content diversity in peach. Here we describe the association between genotypes...

Apple (Malus×domestica Borkh) is among the main sources of phenolic compounds in the human diet. The genetic basis of the quantitative variations of these potentially beneficial phenolic compounds was investigated. A segregating F₁ population was used to map metabolite quantitative trait loci (mQTLs). Untargeted metabolic profiling of peel and flesh tissues of ripe fruits was performed using li...

During the 1995 season, large (-275g), medium (175g) and small (125g) ’O’Henry’ peaches were stored in either air, 5% CO, + 2% 0, or 17% CO, + 6% 0, at 38°F (3.3”C). Large ‘O’Henry’ peaches benefited more from the 17% CO, + 6% 0, than from either the 5% CO, + 2% 0, or the air storage treatment. During the 1996 season, large, medium and small ‘Elegant Lady’ and ’O’Henry’ peaches were stored in a...
