The present work investigates the effect of ripening stage on the chemical composition of essential oil extracted from peel of four citrus: bitter orange (Citrus aurantium), lemon (Citrus limon), orange maltaise (Citrus sinensis), and mandarin (Citrus reticulate) and on their antibacterial activity. Essential oils yields varied during ripening from 0.46 to 2.70%, where mandarin was found to be ...

The aim of present work was to extract pectin from dried orange fruit peels to assess its binding property in tablets using paracetamol as model drug. Initially orange fruit peel powder was subjected to simple water based soxhlet extraction and pectin was isolated using ethyl alcohol as precipitating agent. Thereafter, four batches were formulated using pectin in different proportions. A refere...

Gas chromatography-mass spectrometry (GC-MS) and gas chromatography-olfactometry (GC-O) were used to determine the aromatic composition and aroma active compounds of fruit juice and peel oil of Jinchen sweet orange fruit. Totals of 49 and 32 compounds were identified in fruit juice and peel oil, respectively. GC-O was performed to study the aromatic profile of Jinchen fruit juice and peel oil. ...

Essential oils obtained from certain plants have repellent potency against insects such as mosquitoes. Most repellents on the market synthetic formulation of N, N-diethyl-3-methylbenzamide (DEET) main active ingredient. This study is an attempt to contribute search for effective plant-extracted essential oil, Neem and Orange alternative DEET. The oil Citrus sinensis (sweet orange) peels was ext...

is added to grapefruit pulp the pulp acts as a bland filler and makes an apple pie. If peach is added it makes a peach pie. Citric acid, sugar and peel oil give excellent orange, grapefruit and tangerine jams. A little' peel oil, sunset yellow, No. 6 and sugar makes a good ice cream mix. Add more sugar and you have a good sundae topping. Cake fillings were made from the jams but they gave troub...

Background and study aims  Rectosigmoidoscopy with biopsy has been regarded to be a useful procedure to diagnose gastrointestinal graft-versus-host disease (GVHD). However, little is known about the specific colonoscopic features of gastrointestinal GVHD. In this study, we focused on the 4 unique colonoscopic findings - orange peel appearance, spotty redness, small mucosal sloughing, and diffus...

In this proof of concept study we demonstrate direct utilization of limonene containing waste product orange peel as starting material for a biocatalytic cascade reaction. The product of this cascade is chiral carvolactone, a promising building block for thermoplastic polymers. Four different concepts were applied to augment limonene availability based on either water extraction solely, additio...

Agro-industrial wastes are mainly composed of complex polysaccharides that might serve as nutrients for microbial growth and production of enzymes. The aim of this work was to study polygalacturonase (PG) production by Aspergillus niveus cultured on liquid or solid media supplemented with agro-industrial wastes. Submerged fermentation (SbmF) was tested using Czapeck media supplemented with 28 d...
