The current study underlines biotechnological valorization of the accumulated and the non-efficiently utilized agro-industrial orange peel waste to produce polygalacturonase (PGase), an industrially important enzyme with augmented demands in enzymes markets, from Bacillus licheniformis SHG10. Sequential statistical optimization of PGase production was performed through one variable at a time (O...

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...

The chemical composition, antioxidant and antibacterial activities of essential oil from peel of Citrus unshiu which cultivated in South Korea were investigated. Eight compounds were identified as l-limonene (88.11%), γ-terpinene (4.66%), cyclohexane, 2,4-diisopropenyl-1-methyl-1-vinyl (1.82%), diethyl phthalate (1.02%), β-linalool (0.97%), β-myrcene (0.91%), α-farnesene (0.91%) and o-cymene (0...

Ex situ catalytic pyrolysis of Citrus unshiu (C. unshiu) peel was performed using a tandem μ-reactor-GC/MS consisting of two sequential furnaces. The pyrolyzates of C. unshiu peel, composed mainly of alcohols, ketones and furans produced in the 1st furnace of the reactor, were upgraded to aromatics by the use of catalysts in the 2nd furnace. Compared to wood powder, C. unshiu peel produced larg...

BACKGROUND Citrus junos Tanaka (yuja), a yellow-coloured citrus fruit has traditionally been consumed in Korea, Japan, and China and has been found effective in preventing certain diseases. However, the inhibitory effect of yuja on hepatic lipid accumulation has not been clearly elucidated thus far. METHODS The inhibitory effect of yuja on hepatic lipid accumulation was investigated in both c...

The present paper aims to evaluate antihyperglycemic activity of methanol extract of Citrus limetta fruit peel (MECL) in streptozotocin-induced (STZ; 65 mg/kg b.w.) diabetic rats. Three days after STZ induction, diabetic rats received MECL orally at 200 and 400 mg kg(-1) body weight daily for 15 days. Glibenclamide (0.5 mg kg(-1) p. o.) was used as reference drug. Blood glucose levels were meas...

The volatile and flavonoid compositions of the peel of Citrus medica L. var. Corsican fruits cultivated in Corsica were studied according to the maturity of the citron fruits measured using growing degree-days. Quantitative variation with the stage of development of the fruit was observed using gas chromatography, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrometry...

The essential oil constituents of the peel and leaf of Citrus aurantiumL. (Rutaceae) grown in thenorth of Iran, were analyzed by GC and GC/MS. Fourteen components representing 99.6% ofthe leafoil were identified. The major compounds were linalool (39.4%), linalyl acetate (38.8%)and a-terpineol (7.2%). Twenty constituents consisting 99.4% of the peeloil were identified.The main components were l...

background and objectives: the chemical composition and antimicrobial activity of bitter orange (citrus aurantium) leaf, ripe and unripe peel essential oils, cultivated in southwest of iran, were investigated. materials and methods: the analysis of chemical composition of hydro-distilled essential oils was carried out by gc-ms. the disc diffusion and broth micro-dilution were used to assay the ...
