In the current study, the fatty acids composition of 30 monovarietal apple juices from six cider apple varieties belonging to two categories was analyzed. The different apple juices were obtained from three consecutive harvests (1997, 1998, and 1999). The fatty acids concentration in apple juice together with chemometric techniques such as principal components analysis (PCA), soft independent m...

The human placenta is key to pregnancy outcome, and the elevated oxidative stress present in many complicated pregnancies contributes to placental dysfunction and suboptimal pregnancy outcomes. We tested the hypothesis that pomegranate juice, which is rich in polyphenolic antioxidants, limits placental trophoblast injury in vivo and in vitro. Pregnant women with singleton pregnancies were rando...

The number of documented outbreaks of human infections associated with the consumption of raw fruits, vegetables, and unpasteurized fruit juices has increased in recent years. According to the Centers for Disease Control and Prevention, in the U.S. the number of reported produce-related outbreaks per year doubled between the period 1973-1987 and 1988-1992 (2,24). During both time periods, the e...

Apples ( MALUS sp., Rosaceae) are a rich source of nutrient as well as non-nutrient components and contain high levels of polyphenols and other phytochemicals. Main structural classes of apple constituents include hydroxycinnamic acids, dihydrochalcones, flavonols (quercetin glycosides), catechins and oligomeric procyanidins, as well as triterpenoids in apple peel and anthocyanins in red apples...

Bacteria and molds may spoil and/or contaminate apple juice either by direct microbial action or indirectly by the uptake of metabolites as off-flavours and toxins. Some of these microorganisms and/or metabolites may remain in the food even after extensive procedures. This study aim to identify the presence of molds (including heat resistant species) and Alicyclobacillus spp., during concentrat...

Antioxidants contribute to endogenous photoprotection and are important for the maintenance of skin health. The study was carried out to compare the skin hydration and transepidermal water loss (TEWL) effects of a stable cosmetic preparation containing flavonoids, following two applications a day over a period of tenth week. The skin trans-epidermal water loss and skin hydration effect was meas...

Background Diabetes mellitus type 2 (DM2) is associated with increased oxidative stress and oxidative damage to DNA. An appropriate intake of antioxidants via the diet can improve this disturbed oxidative status [1]. Apples are the most widely consumed fruits in Europe and represent a major source of antioxidants due to their high polyphenol content [2]. Apple pomace as a polyphenol-rich byprod...

Liquid Chromatography coupled to tandem Mass Spectrometry (LC-MS/MS) with an AB SCIEX 4000 Q TRAP system was used for comprehensive fingerprinting of several fruit juices. Metabolomic data processing tools were used for authentication, i.e. classification of juices and adulteration detection. The developed statistical model was able to reliably detect 25% of orange juice adulteration with apple...

Acrylamide concentrations in prune products--baby strained prunes (range = 75-265 µg kg(-1)), baby apple/prune juice (33-61 µg kg(-1)), prune juice (186-916 µg kg(-1)) and prunes (58-332 µg kg(-1))--on the Canadian market were determined. The formation of acrylamide in a simulated plum juice was also investigated under 'drying conditions' in an open vessel at temperatures <100°C for 24 h and un...

Abstract 120 day storage experiment at 4°C, 22°C and 40°C of cloudy apple juice without AA added or juice with 0.006% or 0.024% (w/w) AA added was conducted. The content of polyphenols, 5-(hydroxymethyl)furaldehyde (5-HMF), ascorbic acid, and the color were assessed by HPLC and other analysis techniques. The formation of new particles in juice during storage was studied by electronic scan micro...
