Caffeine reduction in coffee pulp through silage
Biotechnology Advances, 1993Silage tests to study reductions of antiphysiological compounds (caffeine and polyphenols) of fresh coffee pulp during the anaerobic fermentation were done. A concrete silo divided in compartments, with a total capacity of 9 tons of fresh material was utilized.

A study on bioethanol production from cashew apple pulp and coffee pulp waste
Biomass and Bioenergy, 2011Abstract Bioethanol production from dry cashew apple pulp and coffee pulp was investigated. The pulp was digested with 2% sulfuric acid and subjected to high pressure (15 psi) cooking at 120 °C for 10 min followed by further 1 and a half hour pressure cooking at 90 °C to solubilize the pulp.

Accelerated coffee pulp composting
Biodegradation, 1997The effect of two abundant, easily available and very low-cost agro-industrial organic residues, i.e., filter cake from the sugar industry and poultry litter, on the composting stabilization time of coffee pulp and on the quality of the produced compost, was evaluated.

Agricultural Wastes, 1980
Abstract Coffee pulp is a by-product of coffee processing representing about 40% by weight of the ripe coffee fruit. In this paper results of coffee pulp pressing experiments are presented and discussed. Pressing trials were carried out with a batch hydraulic press and evaluated by calculation of two parameters, juice yield and extracted solids ...

Biological pretreatment of coffee pulp
Biological Wastes, 1988Abstract The presence of several antiphysiological factors limit the use of coffee pulp in monogastric and ruminant feeding. Among these the characteristics of its lignocellulosic fraction is important. Twenty-six white rot fungi were grown under solid substrate conditions, using previously ensiled and pressed coffee pulp without adding additional ...

Biotechnology Letters, 1981
Coffee pulp, traditionally considered a highly polluting waste, is evaluated for its potential as biogas substrate via anaerobic digestion. The fibrous nature of the material required long retention times.

Analysis of proanthocyanidins in coffee pulp
Journal of the Science of Food and Agriculture, 1994AbstractData are presented for the condensed tannins content of pulp prepared immediately from die cherries of three cultivars of freshly harvested coffee beans, and for the pulp after drying. The data have been interpreted with reference to purified quebracho profisetinidins (3.13–6.17% on a dry basis (db)) and to the E% values of the anthocyanin ...

Coffee Pulp Vermicomposting Treatment
2000The concept of vermicomposting began with the knowledge that certain species of epigeic earthworms, which live in the litter and primarily feed on pure organic matter (Bouche, 1977; Lavelle, 1981, Abdul and Abdul, 1994) grow in and consume organic waste materials, converting them into an earth-like soil-building substance that forms a beneficial ...

Phenols and caffeine in wet-processed coffee beans and coffee pulp
Food Chemistry, 1991Abstract The contents of low molecular mass phenols and caffeine have been analysed in five samples of beans and the associated pulp, derived from two species of coffee and two associated hybrids. The composition of the coffee beans was consistent with previous reports.

Tannins in wet-processed coffee beans and coffee pulp
Food Chemistry, 1991The tannins contents have been investigated in five samples of beans and the associated pulp, derived from two species of coffee and two associated hybrids. Tannins were not found in any bean sample, and in contrast to previous reports, hydrolysable tannins sensu strictu were not detected in pulp.
