Oxidative stability of chicken burgers using organic coffee husk extract

Food Chemistry, 2022
The antioxidant capacity of organic coffee husk extract (Coffee arabica L.) added to chicken burgers was evaluated. Two formulations were prepared: with addition of the extract (100 and 200 ppm CAE/kg), in addition to control formulations without the addition of antioxidant, and with the addition of synthetic antioxidant.

Steam explosion pretreatment improved the biomethanization of coffee husks

Bioresource Technology, 2017
This study evaluated the potential of energy generation using a combined heat and power co-generation system (CHP) from biogas produced during the anaerobic digestion of coffee husks (CH) pretreated with steam explosion. Pretreatment conditions assessed were time (1, 5, 15 and 60min) and temperature (120, 180 and 210°C).

Coffee Husk Waste for Fermentation Production of Mosquitocidal Bacteria

Journal of Economic Entomology, 2011
Coffee husk waste (CHW) discarded as bio-organic waste, from coffee industries, is rich in carbohydrates. The current study emphasizes the management of solid waste from agro-industrial residues for the production of biopesticides (Bacillus sphaericus, and B. thuringiensis subsp. israelensis), to control disease transmitting mosquito vectors.

Chemical Nature of Spent Coffee Grounds and Husks

Australian Journal of Chemistry, 2020
Waste coffee husks and spent coffee grounds (SCGs) are produced in large qualities worldwide. Characterisation of these waste streams from Australian commercial outlets in terms of lipid, caffeine, and polyphenol content was undertaken giving values up to 10 % lipids and 23 mg g−1 phenols from SCGs, consistent with reports from other parts of the world.

Coffee Husk Briquettes: A New Renewable Energy Source

Energy Sources, 2003
In the rural region of Segundo Frente, in Cuba, due to the present rate of deforestation, the local authorities have carried out severe restrictions over the fuelwood collection, and it is necessary to introduce other sources of cheap and available fuels.

Coffee Husks Characterization for the Fast Pyrolysis Process

Materials Science Forum, 2017
The lignocellulosic biomass is a renewable alternative for fossil fuels. The extensive cultivation of coffee grounds in Brazil generates a large amount of residues, as coffee husks. The work aimed at performing the coffee husks characterization, investigating the viability for fast pyrolysis application.

Gibberellic Acid Production by Solid-State Fermentation in Coffee Husk

Applied Biochemistry and Biotechnology, 2002
Five strains of Gibberella fujikuroi and one of Fusarium moniliforme were screened for the production of gibberellic acid (GA3) in coffee husk, and based on the results, one strain, G. fujikuroi LPB-06, was selected. The comparative production of GA3 by solid-state fermentation and submerged fermentation indicated better productivity with the former ...

Adsorption of Ni(II) on spent coffee and coffee husk based activated carbon

Journal of Environmental Chemical Engineering, 2018
Abstract Adsorption of Ni(II) on low cost activated carbon (AC) from spent coffee (SAC) and coffee husk (HAC) has been studied. Porous textures of adsorbents were characterized by N2 and CO2 sorption measurements. Batch adsorption experiments were performed as a function of adsorbent dose, Ni(II)-concentration and pH.

Detection of adulterations in processed coffee with cereals and coffee husks using capillary zone electrophoresis

Journal of Separation Science, 2009
AbstractThe proposed method for the identification of adulteration was based on the controlled acid hydrolysis of xylan and starch present in some vegetable adulterants, followed by the analysis of the resulting xylose and glucose, which are the monosaccharides that compose, respectively, the two polysaccharides.

Characterization and bioactivities of coffee husks extract encapsulated with polyvinylpyrrolidone

Food Research International
Coffee processing generates large amounts of residues of which a portion still has bioactive properties due to their richness in phenolic compounds. This study aimed to obtain a coffee husks extract (CHE) and to encapsulate it (ECHE) with polyvinylpyrrolidone using a one-step procedure of solid dispersion. The extraction and encapsulation yields were 9.
