Germacrenes in Citrus Peel Oils

Journal of Essential Oil Research, 2001
Abstract The germacrene composition of various citrus peel oils was investigated. Detection and quantification of the thermally sensitive germacrenes A and C was achieved by employing extremely gentle GC conditions with 100°C maximum in injector and GC-oven. Germacrene A was found in all analyzed citrus oils with values from trace level to 0.46% of the

Purification of Citrus Peel Juice and Molasses

Journal of Agricultural and Food Chemistry, 1999
Citrus peel juice and molasses are extremely bitter and unpalatable byproducts of orange and grapefruit juice production. Major components of interest are soluble sugars, glucose, fructose, and sucrose, which account for 60-70% of the dry solids. Analyses indicate that the remaining components are suspended tissue fragments, proteins, organic acids ...

Volatile Constituents of Wild Citrus Mangshanyegan (Citrus nobilis Lauriro) Peel Oil

Journal of Agricultural and Food Chemistry, 2012
Volatiles of a wild mandarin, Mangshanyegan (Citrus nobilis Lauriro), were characterized by GC-MS, and their aroma active compounds were identified by aroma extract dilution analysis (AEDA) and gas chromatography-olfactometry (GC-O). The volatile profile of Mangshanyegan was compared with those of other four citrus species, Kaopan pummelo (Citrus ...

Products From Citrus Peel

ASME 1956 Citrus Engineering Conference, 1956
Almost four million tons of citrus fruit were used by the Florida processing plants last year. Juice obtained from citrus represents only approximately half of the weight of the fruit. Two million tons of peel, pulp and seeds, accumulated yearly at processing plants, presents a challenge and an opportunity.

Valorization of citrus peel waste

2019
Citrus sinensis commercially known as an orange tree has a high pectin ratio and valuable essential oils. The huge amount of orange peel is generated in industries and they can be used as a raw material for essential oils and pectin. To obtain essential oils from orange peels distillation method is used and collected oil is analyzed to determine its d ...

Ruminal digestion kinetics of citrus peel

Animal Feed Science and Technology, 1997
Abstract Three experiments were conducted to investigate digestion kinetics of citrus peel in the rumen of cows fitted with rumen canulae. In the first experiment silage of orange peel was studied, while in the second experiment fresh peels from two lemon varieties were studied in conjunction with orange peel.

Physical Properties of Fermented Citrus Peel

2008 Providence, Rhode Island, June 29 - July 2, 2008, 2008
Each year, the Florida citrus juice industry produces about 3.5~5.0 million tons of wet peel waste, which are currently dried and sold as cattle feed, often at a loss, to dispose of the waste residual. Profitability would be greatly improved if the peel waste could be used to produce higher value products.

Pyrolysis and catalytic upgrading of Citrus unshiu peel

Bioresource Technology, 2015
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.

Bioactive glycosides in citrus fruit peels

1999
Abstract Since 1980's we have been investigating bioactive compounds in citrus fruit peels. We have successfully isolated seventy-three glycosides including thirty-four new compounds. They were flavonoid glycosides, phenylpropanoid glycosides, terpenoid glycosides, limonoid glycosides, and alkyl glycosides.

Enzymic peeling of Indian grapefruit (Citrus paradisi)

Journal of the Science of Food and Agriculture, 2001
AbstractThe tough nature of grapefruit (Citrus paradisi) peel and its close adherence to the inner fruit sections limit the industrial processing of grapefruit. Two commercial peeling enzymes coded as ‘Brand A’ and ‘Brand B’ were studied for enzymic peeling of Indian grapefruit by vacuum infusion.
