Concerns have recently been raised about the presence of metals in apple juices. As such, the concentration of aluminum (Al), arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), manganese (Mn), mercury (Hg), and zinc (Zn) were measured in six commercially available brands of apple juice and three organic brands. The concentrations of total As, Cd, Cr, Cu, Hg, and Zn in all nine a...

Background and Purpose: Patulin is one of the important mycotoxins, produced by a wide range of molds, including Penicillium, Aspergillus, and Bysochlamys. Patulin is mainly found in the rotten parts of fruits and vegetables, such as apples, pears, peach, apricots, and grapes. Currently, the Codex Alimentarius and Food and Drug Administration have recommended a maximum level of 50 μg/L patul...

MATERIAL & METHODS We have analyzed the loss of enamel and dentine after exposure to different non-alcoholic drinks with a simple new method using bovine teeth. 100 enamel and 100 dentine specimens from freshly extracted bovine incisors were randomly attributed to 10 groups (n=10 for enamel and dentine each). Prior to the start of the experiment all specimens were weighed using a precision bala...

Processing and storage of apple juice often triggers quality deterioration regarding nutritional valuable compounds and unfavourable color changes resulting from browning. Fluorescence and near-infrared (NIR) spectroscopy were applied to detect such quality loss in apple juice. Juice samples were produced from Malus x domestica 'Pinova', stored at 20 °C for 4 days or heated at 80 °C for 10 min ...

abstract nanoparticles (nps) are increasingly recognized as their usage in biological applications including nanomedicine and food safety. purpose of this study was study on comparison of antibacterial effect of zno nanoparticles in apple juice at 25 and 4 ° c. the present study investigated the antibacterial activity of zno was tested against listeria monocytogenes, escherichia coli, staphyloc...

The effect of soluble solids on the Zetapotential (ξ) of a cloudy apple juice was investigated. Apple juice was enzymatically treated with pectinolytic enzymes and diafiltred with a polysulphone UF membrane (100 kDa) to eliminate soluble solids. Most soluble solids were removed after 4 equivalent sample volumes (ESV) of washing water. During a second period, from 5 to 23 ESV, diafiltration rate...

Abstrac: This study was carried out to investigate the effect sodium benzoate on apple and apricot blend juice. The samples were; apple juice (T ), apricot juice (T ), 75% apple and 25% apricot juice (T ), 50% apple and 50% 1 2 3 apricot (T ), 25% apple and 75% apricot juice (T ). From (T ) to (T ) above concentrations were repeated with 4 5 6 10 0.01% sodium benzoate as preservative. The sampl...

OBJECTIVE To determine whether infantile colic (IC) is associated with malabsorption of carbohydrates present in fruit juices. METHODS In this double-blind study, parents of 30 healthy infants (5.1 +/- 0.7 months, 7.4 +/- 1.0 kg, 64 +/- 4 cm) were administered a questionnaire to quantitatively assess IC. Thereafter, they were divided into 2 groups, 16 infants with and 14 without IC. Within ea...

food safety is a global concern due to an increasing awareness of consumers concerning exposure of foods to chemicals and contamination with such hazardous biochemicals as dioxins, mycotoxins, pesticides, polycyclic aromatic hydrocarbons, drugs and hormones. patulin is one of the most injurious mycotoxins produced by a variety of molds, particularly aspergillus and penicillium species. based on...

Apple juice samples intended for infants purchased in Navarra (Spain) have been analyzed for PAT occurrence. Two capillary electrophoresis methods, based on a MEKC and a CEC system, and an HPLC method were evaluated for the aforementioned study. The CEC system gave less satisfying separations and several practical problems, so samples have been analyzed by MEKC and HPLC. Both methods have been ...
