Extração de óleo de café verde utilizando banho ultrassônico / Extraction of green coffee oil using ultrasonic bath

Objective: To evaluate the effect of 10% cream of green coffee oil on skin Wounds in Wistar Rats. Materials and Methods: We used 36 Wistar Rats, randomly divided between 3 groups: Inert Group (I, n = 12), Wounds were cleaned and treated with cream without the active ingredient once a day; Green Coffee (CV, n = 12), Wounds were cleaned and treated with 10% green coffee cream once a day; Dexpanthenol (SD, n = 12), Wounds were cleaned and treated with 5% Dexpanthenol once a day. As lesions had been generated by 8mm drilling, the same have been treated topically every day. On the 3rd , 7th and 14th day after Surgery, four Animals / group were sacrificed, or a Fragment of skin around the Wound was collected and processed histologically. Results: Green coffee cream is a 10% stimulus in the Repair process, such as Wounds without signs of infection, and an increase in the number of mononuclear Cells and fibroblasts (p 0.05), good entanglement of collagen Fibers and less healing time presented to the other studied groups. Conclusion: 10% green coffee oil has Pharmacological potential in the healing of skin Wounds.

In the search for oils of commercial interest that serve as new sources for the generation of cosmetic, pharmaceutical, or nutraceutical products, the green coffee beans oil (Coffea arabica L.) was studied. This research aimed to evaluate the oxidative stability of microencapsulated green coffee oil (Coffea arabica) by spray drying. The green coffee oil emulsions were produced by microfluidization using mesquite gum and octenyl succinic anhydride modified starches (OSA-starch) as wall-material. The particle size, polydispersity, and zeta potential on the microfluidized emulsions were optimized. The results showed that microfluidization had positive effects on the reduction of the emulsion droplets and the zeta potential, developing stable emulsions for both polymers. Then, the optimal microfluidization conditions were used to evaluate the impact of the spray drying conditions on the microencapsulation efficiency, morphology, and oxidation stability of the green coffee oil microcapsules under accelerated storage conditions (32% relative humidity (RH) at 25 °C). The microencapsulation efficiency was approximately 98% for both wall-materials. The morphology of the microcapsules showed spherical shapes and polydisperse sizes, a typical characteristic of spray-dried powders. The oxidative stability of the microcapsules was lower than the bulk green coffee oil (87.39 meq of O2/kg of oil), reaching values of 60.83 meq of O2/kg of oil for mesquite gum and 70.67 meq of O2/kg of oil for OSA-starch. The microcapsules produced have good potential for the development of nutraceutical foods or cosmetic formulations with adequate stability.

The aim of this study was to evaluate the adulticidal effects of green coffee oil (GCO) and roasted coffee oil (RCO) on two species of fruit flies (Tephritidae) include Ceratitis capitata (Wiedemann) and Anastrepha fraterculus (Wiedemann). Adult flies of both species were exposed to GCO and RCO at 2%, 3%, and 4% dilutions in water under Potter spray tower. In general, exposure to GCO and RCO at the three dilutions resulted in higher numbers of dead adults of both species compared to the control populations. The mortalities increased substantially between 60–90 minutes after initial exposure. The 2% GCO dilution reached a maximum of 77.0% corrected mortality of A. fraterculus at 360 minutes. In general, the toxic effect of coffee oils occurred more rapidly in C. capitata than in A. fraterculus. GCO (2% and 3%) and RCO (2%) showed promising results for fruit fly management.
