1. EFFECT OF ECOFRIENDLY BIO-BASED SOLVENTS ON OIL EXTRACTION FROM GREEN COFFEE BEAN AND ITS INDUSTRIAL PRESS CAKE
Abstract Oil recovery, retention index, and thermodynamic parameters of green coffee beans (GCB) and its press cake (PC) extraction using bio-based solvents were investigated. The extraction parameters investigated were temperature (35 to 55 °C), type of material (coffee beans and press cake), and type of solvent (ethanol, acetone, and ethyl acetate), at a

2. Improved green coffee oil antioxidant activity for cosmetical purpose by spray drying microencapsulation
AbstractThe oil extracted by cold pressing unroasted coffee beans, known as green coffee oil, has been widely used for cosmetic purposes. The objective of this work was to prepare and characterize microcapsules containing green coffee oil and to verify its antioxidant activity under the effect of light, heat and oxygen. The encapsulating material was arabic

4. Extraction of caffeine, chlorogenic acids and lipids from green coffee beans using supercritical carbon dioxide and co-solvents
The paper reports on experimental data on the extraction of caffeine, coffee oil and chlorogenic acids from green coffee beans using pure supercritical CO2 and supercritical CO2 modified with ethanol (5% w/w) and isopropyl alcohol (5% w/w) at 50 and 60ºC and 15.2 24.8 e 35.2 MPa. In this study extraction kinetics were obtained for all assays i.e. samples we

5. Supercritical CO2 recovery of caffeine from green coffee oil: new experimental solubility data and modeling
The caffeine solubility in supercritical CO2 was studied by assessing the effects of pressure and temperature on the extraction of green coffee oil (GCO). The Peng-Robinson¹ equation of state was used to correlate the solubility of caffeine with a thermodynamic model and two mixing rules were evaluated: the classical mixing rule of van der Waals with two ad

6. Physiologic selectivity of insecticides used in coffee crop on the predators Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) and Cryptolaemus montrouzieri Mulsant, 1853 (Coleoptera: Coccinellidae) / SELETIVIDADE FISIOLÃGICA DE INSETICIDAS UTILIZADOS EM CAFEEIRO SOBRE OS PREDADORES Chrysoperla externa (HAGEN, 1861) (NEUROPTERA: CHRYSOPIDAE) E Cryptolaemus montrouzieri MULSANT, 1853 (COLEOPTERA: COCCINELLIDAE).
For the use of predators for pest control in the coffee crops in association with pesticides it is important that these compounds be selective to these natural enemies The physiologic selectivity of pesticides used in coffee crop on these predators Chrysoperla externa (Hagen 1861) (Neuroptera Chrysopidae) and Cryptolaemus montrouzieri Mulsant 1853 (Coleopter

7. Diseases under organic cultivation of coffee (Coffea arabica L.): epidemiology and alternative control / âDoenÃas em cultivo orgÃnico do cafeeiro (Coffea arabica L.) : epidemiologia e controle alternativoâ
In the years of 2005 and 2006 two trials were installed in eight year old coffee plantations of the cv. Acaià MG-474-19, under organic and conventional crop systems, in Santo AntÃnio do Amparo, Minas Gerais. The progress of rust and brown eye spot diseases of coffee was assessed as a function of the effect of different biofertilizers, between December/2004

9. Supercritical fluid extraction and separation of coffe active principle / Extração e recuperação dos principios ativos do cafe utilizando fluidos supercriticos
Active principles obtained from natural products are widely used as raw materials for a large number of cosmetics, pharmaceutical and food products. The recovery of these compounds by conventional processes is laborious and in many cases may cause irreversible damages. The versatile supercritical solvents technology rises as an alternative to these processes
