abstract: due to the importance of essential oils and their use in various industries, the essential oils of four types of citrus consisting of orange (c. sinesis), tangerine (c. reticulate), sweet lemon (c. limetta) and sour lemon (c. limon) were extracted and subjected to chemical analysis to identify and evaluate the chemical constituents of the oils. the average essential oils of orange, ta...

The peel components of Mandarin, Sour lemon and Sour orange were analyzed. Peel flavorcomponents were extracted using cold-press method and eluted using n-hexane. All compoundswere analyzed using GC-FID and GC-MS. Twenty-seven, Twenty-four and Twenty-nine peelcomponents were identified in Mandarin, Sour lemon and Sour orange respectively. They includealdehydes, alcohols, esters, monoterpenes an...

The characteristic aroma compounds of Citrus natsudaidai Hayata essential oil were evaluated by a combination of instrumental and sensory methods. Sixty compounds were identified and quantified, accounting for 94.08% of the total peel oil constituents. Limonene was the most abundant compound (80.68%), followed by gamma-terpinene (5.30%), myrcene (2.25%) and alpha-pinene (1.30%). Nineteen compou...

The peel of Gac fruit (Momordica cochinchinensis Spreng.) contains high levels of bioactive compounds, especially carotenoids which possess significant antioxidant capacities. However, the peel of Gac is regarded as a waste from the production of carotenoid-rich oil from Gac fruit. In this study, carotenoids of Gac peel were extracted by microwave-assisted extraction (MAE) and ultrasound-assist...

Background: Orange peel essential oils were obtained using supercritical fluid extraction. This method is an important high scaling extraction methods that used for extraction of plant and animal extracts. Methodology: The experimental parameters of SFE such as temperature, pressure, and extraction time and modifier volume were optimized using a central composite design after a 24-1fractional ...

the phenolic compounds of pomegranate (punica granatum l.) peel extracted by two methods (solvent and ultrasound-assisted) with five solvents (acetone, methanol, ethanol, water and ethyl acetate) were compared with supercritical fluid extraction (sfe). the total phenolic compounds were determined according to the folin-ciocalteu reagent using tannic acid as standard. the overall results showed ...

Mango processing produces significant amount of waste (peels and kernels) that can be utilized for the production of value-added ingredients for various food applications. Mango peel and kernel were dried using different techniques, such as freeze drying, hot air, vacuum and infrared. Freeze dried mango waste had higher antioxidant properties than those from other techniques. The ORAC values of...

the effect of different juice extraction treatments on the qualitative properties of lime juice was investigated. samples were selected from jahromi lime variety and lime juice extracted by means of a screw type juice extraction device. the mechanical parameters of the helical juice extractor [screw velocity (270, 360 and 450 rpm), outlet pressure (minimum, medium vs. maximum)] and lime pretrea...

studies had shown that oxygenated compounds are important in food products. it seems that extraction methods had a profound influence on this factor. the goal of the present study is to investigate on flavor components of murcott mandarin obtained using cold-press and hydro distillation. in the last week of january 2012, at least 50 mature fruit were collected from many parts of the same trees....

the effects of mandarin scions on peel components and juice quality parameters were investigated in this study. peel flavor components were extracted by using cold-press and eluted by using n-hexane. then all analyzed by gc-fid and gc-ms. total soluble solids, total acids, ph value, ascorbic acid as well as density and ash were determined in juice obtained from mandarin scions. twenty-seven, tw...
