Aureobasidium pullulans strain Ach1-1 was recently isolated for its biocontrol effectiveness against Penicillium expansum, the causal agent of blue mold on harvested apples. In the present study, strain Ach1-1 was found to be very effective in controlling P. expansum on apple wounds. For in vitro tests, strain Ach1-1 and P. expansum were cocultured in the presence of apple juice (0 - 5%) using ...

BACKGROUND Considerable research has been directed towards the roles of metal ions in nutrition with metal ion toxicity attracting particular attention. The aim of this study is to measure the levels of metal ions found in selected beverages (red wine, stout and apple juice) and to determine their potential detrimental effects via calculation of the Target Hazard Quotients (THQ) for 250 mL dail...

in this study, phenolic compounds of evening primrose leaves (oenothera biennis) were extracted with aceton 70%, ethanol 70% and methanol 70%. total phenolic content of aceton extract was significantly higher than the ethanolic and methanolic extracts. extracts were tested for their antimicrobial activity against lactobacillis plantarum and saccharomyces cerevisiae, using micro broth dilution m...

BACKGROUND Polyphenols are chemical compounds of the secondary plant metabolism. High concentrations can be found in various fruits including apples, berries and grapes. Polyphenols are associated with numerous health beneficial effects including a reduced risk for cardiovascular disease or diabetes. The human body cannot synthesize or store polyphenols and relies on continuous replenishment by...

Using natural antioxidants instead of synthetic additives for food stabilisation is at the forefront of research in food formulation. Matrix interactions and stability studies of the incorporated foods are necessary prior to further processing. In this study, apple peel phenolics were added to a commercial bottled tomato juice. The juice was opened and then stored in the presence of air in the ...

The pectin lyase gene pnl-zj5a from Aspergillus niger ZJ5 was identified and expressed in Pichia pastoris. PNL-ZJ5A was purified by ultrafiltration, anion exchange and gel chromatography. The Km and Vmax values determined using citrus pectin were 0.66 mg ml(-1) and 32.6 μmol min(-1) mg(-1) , respectively. PNL-ZJ5A exhibited optimal activity at 43°C and retained activity over 25-50°C. PNL-ZJ5A w...

This study aimed to evaluate effectiveness of Phosphoryl-Oligosaccharides of Calcium (POs-Ca) added to apple juice on enamel erosion. Five juices were prepared by adding 0%, 0.5%, 1%, 1.5% or 2% POs-Ca to commercial apple juice, and subjected to Visual Analogue Scale (VAS) taste evaluation and pH and calcium/inorganic-phosphates analyses. To evaluate erosion, polished bovine enamel blocks were ...

Apple juice, for its sensory and nutritional qualities, is consumed by people of all ages. Apples are an excellent source of several phenolic compounds and the presence of polyphenols is recognized for their health promoting antioxidant properties. Thermal pasteurization of fruit juices is the conventional method used for their preservation. Therefore, this constitutes the most extensively avai...

PURPOSE The aim of this study was to evaluate the antiproliferative activity in breast cancer cells and the inhibition of tumorigenesis in pre-neoplastic cells of a new apple cultivar with reddish pulp, called the Pelingo apple. METHODS The antiproliferative activity was evaluated in MCF-7 and MDA-MB-231 human breast cancer cells. The inhibition of tumorigenesis was performed in JB6 promotion...

Pectinase (Pectin methyl esterase) produced by Aspergillus niger in solid state fermentation of apple pomace using the optimized conditions was partially purified by (NH4)2SO4 fractionation (20-80% concentration). The purified enzyme was found to be stable up to 60 days. It remained heat stable up to 50oC but completely inactivated at 90oC. The partially purified enzyme showed highest activity ...
