background & aims of the study: today, the environment pollution with heavy metals has increased. it is important to study various types of pollutions specially those regarding fruits. the effect of pollutions on food safety for human consumption is a global concern.  this study was conducted for health assessment of heavy metals pollution (cadmium, lead, and arsenic) in citrus marketed in tehr...

Citrus aurantium subsp. bergamia is a member of the Rutaceae. In Turkish folk medicine, Citrus species have several uses such as for their appetizing, diaphoretic, antiseptic, analgesic and anti-inflammatory effects (1). The Bergamot oil (BO) is a roughly pear-shaped citrus fruit. The fruit is produced in Italy, East Africa, Ivory Coast, Argentina, Brazil, Turkey and some other Mediterranean co...

Carotenoids are the main pigments responsible of the colouration of Citrus fruits. The beta-cyclization of lycopene, catalysed by the lycopene beta-cyclases (beta-LCY), seems to be a key regulatory step of the carotenoid pathway. In the present study, two beta-LCYs from orange fruits (Citrus sinensis), named Csbeta-LCY1 and Csbeta-LCY2 have been isolated and the activity of the encoded proteins...

In the present work, the effect of initial pH of methylene blue solution on the kinetics of dye sorption from synthetic aqueous solution by a natural waste material namely: orange peels, was studied. Kinetic data were measured in batch conditions. Methylene blue uptake was time contact and solution initial pH dependent. Maximum dye sorption was found to occur at initial pH 9. Two simplified kin...

Pectinolytic enzymes are related that hydrolyze pectic substances. of great interest in industrial applications for softening fruits, extracting and clarifying juices, olive oil, retting textile fibers, preparing gel, isolating protoplasts. The current work presents acidic extracellular pectinase production using low-cost agro-industrial waste with the indigenously isolated novel strain Aspergi...

The aim of this study was to synthesize chemically activated carbons from different agricultural residues, i.e., pistachio shell (PS), bitter orange peel (OP), and saffron petal (SP), subsequently use them as supports for loading a Ni catalyst. Supercritical water gasification bio-oil applied investigate the catalytic performance resulting catalysts. physicochemical properties carbon (ACs) cata...

Loquat (Eriobotrya japonica Lindl.) can be sorted into red- and white-fleshed cultivars. The flesh of Luoyangqing (LYQ, red-fleshed) appears red-orange because of a high content of carotenoids while the flesh of Baisha (BS, white-fleshed) appears ivory white due to a lack of carotenoid accumulation. The carotenoid content in the peel and flesh of LYQ was approximately 68 μg g(-1) and 13 μg g(-1...
